What are Hypermature Cataracts?
Hypermature cataracts represent one of the most advanced and potentially sight-threatening stages of cataract development. When a cataract is left untreated for a prolonged period, it can progress beyond the mature stage to become a hypermature cataract. At this stage, the lens undergoes significant structural changes that can lead to serious complications, including permanent vision loss. At Vasan Eye Care, our experienced ophthalmologists specialise in the surgical management of hypermature cataracts, using advanced techniques to restore vision safely and effectively.
Understanding Hypermature Cataracts
Hypermature cataracts are cataracts that have progressed beyond the mature stage, where the entire lens has already become opaque. In a hypermature cataract, the lens proteins begin to break down, liquefy, or shrink, leading to further structural deterioration of the lens. This advanced stage of cataract development poses unique challenges for both the patient and the surgeon.
When we talk about the natural progression of cataracts, it is helpful to understand the stages. A cataract begins as an immature cataract, where only part of the lens is clouded. It then progresses to a mature cataract, where the entire lens becomes opaque and white. If a mature cataract is not treated, it advances to become a hypermature cataract. At this stage, the lens cortex may liquefy, the capsule may wrinkle, and the overall structure of the lens becomes compromised.
Think of the lens as a grape. In an immature cataract, parts of the grape have started to lose their freshness. In a mature cataract, the grape has become uniformly cloudy but firm. In hypermature cataracts, the grape has become overripe — it may turn to mush inside, shrivel up, or develop hard, calcified patches. This is why hypermature cataracts are sometimes referred to as an overripe cataract — the lens has gone well past the point where surgery should ideally have been performed.
Hypermature cataracts are particularly common in India and other developing countries, where access to timely eye care can be limited, and patients may delay surgery due to fear, financial constraints, or outdated cultural beliefs that a cataract must “ripen” before it is removed. A hypermature cataract can take one of several forms. In some cases, the cortex liquefies and the dense nucleus sinks to the bottom of the capsular bag, a condition known as a morgagnian cataract. In other cases, the lens may shrink and become calcified. Both presentations of hypermature cataracts demand careful surgical planning.
The term white cataract is often used to describe both mature and hypermature cataracts, as the lens appears entirely white or opaque. However, it is important to distinguish between a simple white cataract and a true hypermature cataract, because the surgical risks and complications differ significantly.

What are the Symptoms of Hypermature Cataracts?
Hypermature cataracts symptoms are typically severe, as the condition represents the most advanced stage of cataract development. Patients with hypermature cataracts often present with profound visual impairment that significantly affects their ability to carry out daily activities.
Hypermature Cataracts Symptoms to Watch For
Symptom | Description |
Severe vision loss | Near-complete or complete loss of useful vision in the affected eye |
White pupil (leukocoria) | The pupil appears white instead of black due to the totally opaque lens |
Perception of light only | In advanced cases, the patient may only be able to perceive light and its direction |
Pain or discomfort | Some hypermature cataracts can cause secondary glaucoma, leading to eye pain and headache |
Redness of the eye | Inflammation caused by leaking lens proteins (phacolytic glaucoma) can cause redness |
Swelling of the eye | The eye may appear swollen due to increased intraocular pressure or inflammation |
Watering of the eye | Excessive tearing may occur as a response to irritation or inflammation |
Inability to recognise faces | Patients with hypermature cataracts often cannot recognise people even at close range |
Difficulty navigating surroundings | Profound vision loss makes it challenging to move about safely |
Loss of colour perception | The ability to distinguish colours is severely diminished |
Hypermature cataracts symptoms develop gradually as the cataract progresses from the mature to the hypermature stage. However, some complications such as phacolytic glaucoma or lens-induced uveitis can cause a sudden worsening of symptoms, including acute pain and redness. If you notice any sudden change in your eye condition, it is important to seek immediate medical attention.
It is worth noting that hypermature cataracts symptoms may be present in one eye or both eyes. When hypermature cataracts affect both eyes, the patient may become functionally blind, unable to perform even basic self-care tasks without assistance.
When Should You See a Doctor?
Please visit an eye specialist urgently if:
• Your vision in one or both eyes has reduced to perception of light or hand movements only
• The pupil of the affected eye appears white, milky, or visibly different
• You have been living with a long-standing cataract and have noticed sudden worsening
• You are experiencing new eye pain, redness, or headache along with vision loss
• You notice swelling of the eye or excessive watering
• You can no longer recognise familiar faces, even at close range
• You are unable to move about safely due to poor vision
• You are a carer of an elderly relative whose vision has been declining and who has been reluctant to seek surgery
• You are over 60 and have not had a cataract evaluation for several years
Hypermature cataracts should not be left untreated. The sooner hypermature cataracts treatment begins, the lower the risk of complications such as lens-induced glaucoma or permanent optic nerve damage.
What are the Types of Hypermature Cataracts?
Understanding the different types of hypermature cataracts is essential for proper diagnosis and surgical planning. Hypermature cataracts can be broadly classified based on the structural changes that occur within the lens.
The Main Types of Hypermature Cataracts
- Morgagnian Cataract A morgagnian cataract is the most recognised type of hypermature cataract. In this form, the lens cortex undergoes complete liquefaction, turning into a milky fluid. The dense, hard nucleus is no longer supported by the cortex and sinks to the bottom of the capsular bag under the force of gravity. This creates a characteristic appearance where the upper part of the lens appears clear or semi-transparent (due to the liquefied cortex), while the brown or dark nucleus sits at the bottom. A morgagnian cataract presents unique surgical challenges — the liquefied cortex means that the capsular bag is under pressure, and opening the anterior capsule (capsulotomy or capsulorhexis) must be done with extreme care. The morgagnian cataract is named after the Italian anatomist Giovanni Battista Morgagni, who first described this condition.
- Sclerotic (Shrunken) Hypermature Cataract In this type of hypermature cataract, instead of liquefying, the lens cortex gradually loses water and the entire lens shrinks in size. The lens becomes dense, calcified, and extremely hard. The capsule appears wrinkled and may develop calcium deposits on its surface. A sclerotic hypermature cataract is technically demanding to operate upon because the extremely hard nucleus is resistant to fragmentation by standard phacoemulsification. In such cases, the surgeon may need to use higher energy levels or opt for a manual surgical technique.
- Hypermature Cataract with Capsular Calcification In some cases of hypermature cataracts, calcium deposits accumulate on the lens capsule, giving it a white, chalky appearance. This calcification can make it difficult to create a smooth, round capsulotomy during surgery. The capsule in these hypermature cataracts may also become brittle and prone to tearing.
Relationship Between White Cataract and Hypermature Cataracts
A white cataract is a broad term that refers to any cataract where the lens appears completely white. Both mature cataracts and hypermature cataracts can present as a white cataract. However, the distinction is important because hypermature cataracts carry a much higher risk of surgical complications. When a patient presents with a white cataract, the ophthalmologist must carefully assess whether it is a mature or hypermature stage before planning surgery.
Morgagnian Cataract as a Subset of Hypermature Cataracts
It is important to understand that every morgagnian cataract is a type of hypermature cataract, but not every hypermature cataract is a morgagnian cataract. The morgagnian cataract specifically refers to the variant where cortical liquefaction and nuclear descent have occurred. Other forms of hypermature cataracts, such as the sclerotic type, involve different pathological changes.
What Causes Hypermature Cataracts?
Hypermature cataracts develop when a cataract is allowed to progress without timely treatment. Understanding the causes of hypermature cataracts helps in prevention and early intervention. The causes can be divided into direct causes and contributing factors.
Primary Causes of Hypermature Cataracts
Delayed or Neglected Cataract Treatment: This is the single most common cause of hypermature cataracts. When a mature cataract is not surgically removed in a timely manner, it continues to degenerate and becomes hypermature. In India, delayed treatment remains a leading cause of hypermature cataracts due to barriers in accessing eye care services, particularly in rural and semi-urban areas.
Advanced Age: Age-related cataracts are the most common type of cataract worldwide. In elderly patients who do not seek treatment, the cataract naturally progresses through all stages, eventually reaching the hypermature stage. Hypermature cataracts are therefore more frequently seen in very elderly individuals.
Lack of Awareness: Many patients, particularly in underserved communities, are not aware that cataracts can and should be treated surgically. This lack of awareness contributes significantly to the development of hypermature cataracts.
Risk Factors for Hypermature Cataracts
Risk Factor | How It Contributes to Hypermature Cataracts |
Poor access to eye care | Patients in remote areas may not have access to surgical facilities, allowing cataracts to progress to the hypermature stage |
Fear of surgery | Some patients avoid cataract surgery due to fear, allowing the cataract to become hypermature |
Financial constraints | The cost of surgery and travel may prevent timely treatment, leading to hypermature cataracts |
Diabetes mellitus | Diabetes accelerates cataract formation and may hasten progression to hypermature cataracts |
Chronic steroid use | Long-term use of corticosteroids promotes cataract development and can contribute to rapid progression |
Eye trauma | A traumatic cataract may progress rapidly to the hypermature stage if not treated |
Ultraviolet radiation exposure | Prolonged sun exposure without eye protection accelerates lens changes over time |
Smoking | Smoking is a well-established risk factor for cataract development and progression |
Family history | A genetic predisposition to cataract formation may increase the likelihood of developing hypermature cataracts if treatment is delayed |
Why Hypermature Cataracts Are Still Common in India
Despite advances in eye care and the availability of subsidised cataract surgery programmes, hypermature cataracts continue to be a common presentation in Indian eye hospitals. The causes are multifactorial: limited access to eye care in rural areas, lack of awareness about surgical options, cultural beliefs that cataracts must “ripen” before surgery, and financial barriers all contribute to the delayed presentation of hypermature cataracts.
At Vasan Eye Care, we actively work to address these barriers through community outreach programmes, affordable surgical options, and patient education initiatives aimed at reducing the burden of hypermature cataracts across the country.
How Do Doctors Diagnose Hypermature Cataracts?
Diagnosing hypermature cataracts requires a comprehensive eye examination. Because hypermature cataracts can cause complications that affect other parts of the eye, the evaluation must be thorough.
Clinical Examination for Hypermature Cataracts
- Visual Acuity Test Patients with hypermature cataracts typically have very poor visual acuity. In many cases, vision is reduced to perception of light only, or the ability to count fingers at very close range. This is the first step in assessing the severity of hypermature cataracts.
- Slit Lamp Biomicroscopy The slit lamp examination reveals the characteristic features of hypermature cataracts. In a morgagnian cataract, the slit lamp shows a milky white liquefied cortex with a dense brown nucleus lying at the bottom of the capsular bag. In a sclerotic hypermature cataract, the lens appears shrunken with a wrinkled capsule. Calcium deposits on the capsule may also be visible.
- Intraocular Pressure Measurement Measuring the eye pressure is critical in cases of hypermature cataracts because these cataracts can cause secondary glaucoma. Phacolytic glaucoma, caused by leakage of high molecular weight proteins through the intact but permeable capsule of a hypermature cataract, is a known complication. Elevated intraocular pressure requires immediate management.
- Dilated Eye Examination While the dense opacity of hypermature cataracts often prevents a clear view of the retina, the doctor will attempt to examine the posterior segment to the extent possible.
- B-Scan Ultrasonography Because the dense opacity of hypermature cataracts prevents direct visualisation of the retina, B-scan ultrasound is essential to assess the health of the retina and vitreous before planning surgery. This investigation helps rule out retinal detachment, vitreous haemorrhage, or intraocular tumours behind the opaque lens.
- A-Scan Biometry This test measures the length of the eye and the curvature of the cornea to calculate the power of the intraocular lens (IOL) that will be implanted during surgery. Accurate biometry is particularly important in cases of hypermature cataracts, as the altered lens can affect the measurements.
- Optical Biometry or IOL Master A non-contact method of measuring eye dimensions for IOL power calculation. In some hypermature cataracts, the dense opacity may prevent optical biometry from working, in which case ultrasound-based methods are used.
- Anterior Segment Optical Coherence Tomography (AS-OCT) This imaging technique can provide detailed information about the anterior chamber depth, lens thickness, and capsular integrity in cases of hypermature cataracts.
- Specular Microscopy This test evaluates the health of the corneal endothelial cells. In patients with long-standing hypermature cataracts, the corneal endothelium may be compromised, which affects surgical planning and prognosis.
Differential Diagnosis
When a patient presents with a white cataract, the ophthalmologist must determine whether it is a mature cataract, a hypermature cataract, a morgagnian cataract, or an intumescent cataract (a swollen lens). Each of these conditions requires a different surgical approach, making accurate diagnosis of hypermature cataracts essential.
What Does Hypermature Cataracts Treatment Look Like?
Hypermature cataracts treatment is primarily surgical. Unlike early-stage cataracts where observation may be appropriate, hypermature cataracts require prompt surgical intervention to prevent further complications and restore vision. The hypermature cataracts treatment approach depends on the type and severity of the cataract, as well as the presence of any complications. In many cases, hypermature cataracts treatment is a step-by-step process rather than a single intervention.
Hypermature Cataracts Treatment Options
- Pre-operative Management Before surgery for hypermature cataracts, any existing complications must be addressed. If phacolytic glaucoma is present, the intraocular pressure must be brought under control using medications such as timolol, brimonidine, acetazolamide, or mannitol. Anti-inflammatory eye drops may be prescribed to reduce any lens-induced inflammation. A thorough pre-operative assessment, including B-scan ultrasonography, is essential to ensure the retina is healthy before proceeding with surgery.
- Phacoemulsification Surgery Phacoemulsification is the preferred surgical technique for most cataracts, including some cases of hypermature cataracts. In this procedure, a small incision (2.2 to 2.8 mm) is made in the cornea, and an ultrasonic probe is used to break up the cataract into small fragments that are then aspirated from the eye. An artificial intraocular lens is then implanted. However, performing phacoemulsification on hypermature cataracts presents several challenges. In a morgagnian cataract, the liquefied cortex creates pressure within the capsular bag, making the capsulotomy particularly risky. The extremely hard nucleus in some hypermature cataracts requires higher phacoemulsification energy, which can damage the corneal endothelium. Special techniques used include careful capsulorhexis with trypan blue dye staining, slow decompression with a needle puncture to allow the milky cortex to drain, and high-viscosity ophthalmic viscoelastic devices (OVDs) to maintain the anterior chamber depth and protect the corneal endothelium.
- Manual Small Incision Cataract Surgery (MSICS) For hypermature cataracts with an extremely hard nucleus, manual small incision cataract surgery (MSICS) may be a more suitable option than phacoemulsification. In MSICS, a slightly larger incision (6 to 7 mm) is made, and the entire nucleus is delivered out of the eye in one piece, without the need for ultrasonic fragmentation. MSICS is particularly useful for hypermature cataracts when the nucleus is too hard for safe phacoemulsification, when the corneal endothelium is already compromised, when the capsule is weak or partially damaged, or in a morgagnian cataract with a very large, dense nucleus. MSICS remains one of the most effective and cost-efficient surgical options for managing hypermature cataracts, especially in high-volume eye care centres across India.
- Extracapsular Cataract Extraction (ECCE) In certain complex cases of hypermature cataracts, particularly when the capsule is extensively damaged or there are other complicating factors, a conventional extracapsular cataract extraction may be performed. This involves a larger incision through which the nucleus is expressed and the cortex is aspirated. While ECCE has largely been replaced by phacoemulsification and MSICS, it remains a valuable technique in the surgical management of complicated hypermature cataracts.
- Femtosecond Laser-Assisted Cataract Surgery Advanced femtosecond laser technology can assist in the surgical management of hypermature cataracts. The laser can create precise incisions and assist with the capsulotomy. However, the dense opacity of many hypermature cataracts can limit the ability of the laser imaging system to visualise the lens structures, which may restrict the use of this technology in some cases.
- Post-Operative Care and Recovery After surgery for hypermature cataracts, post-operative care is especially important due to the higher risk of complications associated with advanced cataracts. Medications include antibiotic eye drops, anti-inflammatory drops (steroid and non-steroidal), and sometimes pressure-lowering drops. Follow-up visits are typically scheduled at one day, one week, one month, and three months after surgery. Patients with long-standing hypermature cataracts may need time to adjust to their restored vision, and in some cases the visual outcome may be limited if the retina or optic nerve has been affected by prolonged cataract-related complications. A final spectacle prescription is usually given four to six weeks after surgery, once the eye has fully healed and the refraction has stabilised.
Understanding Morgagnian Cataract in Detail
A morgagnian cataract is a specific and well-known subtype of hypermature cataracts that deserves special attention due to its unique pathology and surgical challenges. In a morgagnian cataract, the cortex of the lens has completely liquefied, creating a milky white fluid inside the capsular bag. The hard, dense nucleus, no longer supported by the surrounding cortex, sinks to the bottom of the bag due to gravity.
The diagnosis of a morgagnian cataract is typically made on slit lamp examination, where the characteristic appearance of a white, fluid-filled capsular bag with a dependent nucleus is visible. In some cases, the nucleus can be seen moving when the patient changes head position, a phenomenon that is virtually pathognomonic of a morgagnian cataract.
Surgical removal of a morgagnian cataract requires meticulous technique. The surgeon must first carefully decompress the capsular bag by releasing the liquefied cortex in a controlled manner. Trypan blue dye is invaluable in these cases, as it stains the capsule and makes it visible against the white cortex. The capsulorhexis must be completed before the nucleus can be addressed. Because the nucleus in a morgagnian cataract is typically very hard, techniques such as mechanical chopping or conversion to MSICS may be necessary.
Despite the challenges, the surgical outcomes for morgagnian cataract are generally favourable when performed by experienced surgeons. Patients with a morgagnian cataract who undergo timely surgery often achieve significant improvement in their vision.
The Difference Between White Cataract, Mature Cataract, and Hypermature Cataracts
Many patients and even some healthcare professionals use the terms white cataract, mature cataract, and hypermature cataract interchangeably. However, these terms describe different stages and conditions, and understanding the differences is clinically important.
White Cataract: A descriptive term that refers to the appearance of a lens that has become completely opaque and white. It is not a specific stage but rather a visual characteristic that can be seen in both mature and hypermature cataracts.
Mature Cataract: One where the entire lens has become opaque, but the lens structure is still largely intact. The cortex is still solid (not liquefied), the capsule is not wrinkled, and the nucleus has not sunk. While vision is severely affected, the surgical risks are lower compared to hypermature cataracts.
Hypermature Cataracts: Represent a more advanced stage where the lens has begun to degenerate beyond simple opacification. The cortex may have liquefied (as in a morgagnian cataract), the lens may have shrunk, calcium may have deposited on the capsule, or the lens proteins may be leaking through the capsule. These changes make hypermature cataracts more dangerous and more challenging to treat surgically.
Distinguishing between a mature cataract and hypermature cataracts is essential because the surgical approach, risks, and post-operative expectations differ considerably.
Overripe Cataract: Why Timely Surgery Matters
The term overripe cataract is a layperson’s expression for a hypermature cataract. Just as a fruit that has gone past its prime becomes soft, mushy, and deteriorated, an overripe cataract is one where the lens has gone well beyond the point at which it should have been removed.
The concept of an overripe cataract highlights the importance of timely surgical intervention. In the past, patients were often advised to wait until their cataract was “ripe” (mature) before undergoing surgery, because older surgical techniques required a firm, mature lens for extraction. This outdated advice has unfortunately persisted in some communities, leading patients to delay surgery far too long. The result is often an overripe cataract that is much more difficult and risky to operate upon.
Modern cataract surgery, particularly phacoemulsification, can be performed safely at almost any stage of cataract development. In fact, operating on an earlier-stage cataract is generally safer and yields better outcomes than waiting for it to become an overripe cataract or a hypermature cataract. At Vasan Eye Care, we strongly encourage patients to undergo cataract surgery at an appropriate time, well before the cataract becomes overripe, to ensure the safest procedure and the best visual outcome.
If you or a family member has been diagnosed with a cataract but has been delaying surgery, please do not wait until it becomes an overripe cataract. Schedule a consultation at your nearest Vasan Eye Care centre to discuss the right timing for your surgery.
Preventing Hypermature Cataracts Through Early Intervention
While cataracts themselves cannot always be prevented, the progression to hypermature cataracts is almost entirely preventable through timely medical intervention. The development of hypermature cataracts is a direct consequence of delayed treatment, and with awareness and access to care, this advanced stage can be avoided. Steps to prevent hypermature cataracts include:
• Regular eye examinations — adults above the age of 40 should have a comprehensive eye examination at least once every two years; those with diabetes or a family history of cataracts should be examined annually
• Early cataract detection — when a cataract is detected early, it can be monitored and surgery can be planned at the optimal time, long before it progresses
• Timely surgical intervention — do not wait for a cataract to “ripen” or become mature before considering surgery; modern techniques allow safe removal at any stage
• Community awareness — educating family members, particularly elderly relatives in rural areas, about the availability and safety of cataract surgery
• Utilising available healthcare services — government-sponsored programmes, charitable organisations, and affordable private eye care centres such as Vasan Eye Care offer cataract surgery at accessible costs
By taking these steps, the burden of hypermature cataracts can be significantly reduced, preventing unnecessary blindness and improving the quality of life for millions of people across India.

Frequently Asked Questions (FAQs)
Yes, hypermature cataracts can be treated, and surgery is the definitive treatment. While hypermature cataracts are more complex to manage than earlier-stage cataracts, modern surgical techniques such as phacoemulsification and manual small incision cataract surgery allow ophthalmologists to safely remove even the most advanced hypermature cataracts. At Vasan Eye Care, our surgeons have extensive experience in treating hypermature cataracts. The key is to seek treatment as soon as possible, because the longer hypermature cataracts are left untreated, the greater the risk of complications. Even in cases where hypermature cataracts have caused secondary glaucoma or inflammation, these complications can be managed before proceeding with definitive surgical hypermature cataracts treatment.
The three main types of cataract surgery used for treating hypermature cataracts and other forms of cataracts are: Phacoemulsification (the most commonly performed type of cataract surgery worldwide, using ultrasonic energy to emulsify and aspirate the cataract through a very small incision of 2.2 to 2.8 mm); Manual Small Incision Cataract Surgery (MSICS), involving a slightly larger incision (6 to 7 mm) with the nucleus removed whole, especially useful for very hard hypermature cataracts and widely practised in India; and Extracapsular Cataract Extraction (ECCE), the oldest modern technique involving a larger incision through which the cataract nucleus is expressed — while less commonly used today, it remains relevant for certain complicated cases. All three types of surgery involve the implantation of an artificial intraocular lens to replace the removed natural lens.
Yes, a hypermature cataract can cause blindness if left untreated. In fact, hypermature cataracts are one of the leading causes of preventable blindness in developing countries, including India. The blindness caused by hypermature cataracts can be of two types: direct visual loss, where the dense opacity blocks almost all light from reaching the retina; and complication-related blindness, where secondary complications such as phacolytic glaucoma, phacoantigenic uveitis, or lens-particle glaucoma can permanently damage the optic nerve and retina, leading to irreversible blindness even after the hypermature cataract is removed. This is why timely treatment of hypermature cataracts is so critical.
Hypermature cataracts can lead to several serious complications if not treated promptly. Phacolytic glaucoma occurs when high molecular weight lens proteins leak through the intact but permeable capsule of a hypermature cataract, clogging the trabecular meshwork. Phacoantigenic (lens-induced) uveitis occurs when the immune system reacts to leaking lens proteins, causing inflammation inside the eye. Lens subluxation or dislocation may occur as the zonular fibres weaken. Capsular rupture may happen spontaneously or during surgery. Corneal decompensation can result from prolonged exposure to inflammatory mediators, leading to corneal swelling and opacity. Retinal damage may occur where hypermature cataracts cause long-standing elevated eye pressure or chronic inflammation.
The time it takes for a cataract to progress to the hypermature stage varies greatly from person to person. In general, an age-related cataract may take several years to progress from the early stages to the hypermature stage. However, in patients with diabetes, trauma-related cataracts, or cataracts associated with chronic steroid use, the progression to hypermature cataracts can be significantly faster. There is no fixed timeline, which is why regular monitoring is important once a cataract has been diagnosed.
Surgery for hypermature cataracts does carry a higher risk of complications compared to surgery for early or moderate cataracts. The challenges include a difficult capsulorhexis, a very hard nucleus, weakened zonules, and compromised corneal endothelium. However, in the hands of an experienced ophthalmologist using modern techniques and equipment, surgery for hypermature cataracts can be performed safely with good outcomes. At Vasan Eye Care, our surgeons are well trained in managing the complexities of hypermature cataracts surgery, ensuring the best possible results for every patient.
The visual outcome after surgery for hypermature cataracts depends on the overall health of the eye, particularly the condition of the retina and optic nerve. If no significant damage has occurred to these structures, patients can expect a substantial improvement in vision after surgery. However, if hypermature cataracts have caused long-standing glaucoma, chronic inflammation, or retinal damage, the visual recovery may be limited. This underscores the importance of seeking early treatment and not allowing cataracts to progress to the hypermature stage.
