What is Presbyopic and Phakic IOL Surgery?
Presbyopic and Phakic IOL Surgery involves implanting specialized intraocular lenses to correct vision problems without removing the natural lens in some cases. Presbyopic IOLs help restore near and distance vision affected by aging, while Phakic IOLs correct refractive errors like high myopia or hyperopia.
Presbyopic and Phakic IOLs in India
Two different problems, two different lens solutions, one underlying idea: you can put an engineered lens inside the eye to solve a vision problem that glasses and contact lenses have been struggling to handle well.
Presbyopic IOLs are for patients, usually over 40, who have lost near vision to the stiffening of the natural lens that comes with age. These lenses are implanted at the time of cataract surgery (or, in some cases, as a clear lens exchange before a cataract forms) to restore clear vision at multiple distances.
Phakic IOLs are different. They go into the eye while the natural lens stays where it is. They are typically recommended for younger patients with high myopia, high hyperopia, or significant astigmatism who are not good candidates for laser vision correction, either because the prescription is too high or because the cornea is too thin.
At Vasan Eye Care, both categories are performed using established microsurgical techniques and high-precision diagnostic platforms. The goal is a stable, long-term refractive outcome that reduces dependence on spectacles and contact lenses across several distances, while keeping the cornea and retina safe.
India has seen steady adoption of premium intraocular lenses over the past decade. The drivers are structural: an ageing population, wider access to refractive evaluation, and slowly improving insurance coverage for lens-based procedures. Presbyopic IOLs, including multifocal, trifocal, and extended-depth-of-focus (EDOF) designs, are now routine offerings in tertiary eye care centres across metros and Tier-2 cities.
Phakic IOLs, particularly the Implantable Collamer Lens (ICL), have also become a widely accepted option for patients with high refractive errors who want to avoid corneal laser surgery. For anyone with a thin cornea or a prescription beyond the reliable range of LASIK, ICL has quietly transformed what is possible.
Indian ophthalmology guidelines rightly insist on detailed pre-operative screening: corneal topography, endothelial cell count, anterior chamber depth assessment, axial length measurement, and macular evaluation. Vasan Eye Care follows these evidence-based protocols and tailors lens selection to each patient’s visual needs, occupation, and ocular anatomy. Get the workup wrong and the lens choice will be wrong, no matter how good the surgery.
Types of Presbyopic and Phakic IOLs Available in India
Different lenses serve different needs and anatomies. The table below summarises the main categories.
| Lens Type | Category | Intended Correction | Key Feature |
|---|---|---|---|
| Multifocal IOL | Presbyopic | Near, intermediate, distance | Splits light across multiple focal points |
| Trifocal IOL | Presbyopic | Near, intermediate, distance | Dedicated intermediate focus for screen and dashboard work |
| EDOF IOL | Presbyopic | Intermediate and distance | Elongated focal range; fewer halos than older multifocals |
| Toric Presbyopic IOL | Presbyopic | Presbyopia with astigmatism | Corrects astigmatism alongside presbyopia |
| Implantable Collamer Lens (ICL) | Phakic | High myopia, hyperopia, astigmatism | Sits behind the iris, in front of the natural lens; reversible |
| Iris-Fixated Phakic IOL | Phakic | Moderate to high refractive errors | Anchored to the iris; used when posterior chamber anatomy is unsuitable |
| Angle-Supported Phakic IOL | Phakic | Selected refractive errors | Used less often today due to concerns about endothelial impact |
Presbyopic & Phakic IOL – How the Procedure Works?
Presbyopic IOL implantation follows the same pathway as modern cataract surgery. The natural lens is removed using phacoemulsification through a small corneal incision (around 2.2 to 2.8 mm), and the chosen presbyopic IOL is inserted. The lens unfolds inside the capsular bag and is centred to provide optimised focus at multiple distances. The surgery itself takes 15 to 25 minutes per eye.
Phakic IOL implantation is fundamentally different. The patient’s own crystalline lens stays in place. The phakic lens, most commonly an ICL, is folded and introduced through a small corneal incision, then positioned behind the iris and in front of the natural lens. Because no tissue is removed, accommodation is preserved in younger patients. This matters: a 28-year-old who gets an ICL still focuses at near the way a 28-year-old should. That is not true of a clear lens exchange with a standard IOL.
Both procedures are performed under topical anaesthesia as day-care surgery.
When Is Presbyopic or Phakic IOL Surgery Necessary?
Patients are considered for these procedures when spectacles or contact lenses are no longer meeting their visual or lifestyle needs. Common triggers include:
- Needing to hold reading material at arm’s length
- Difficulty shifting focus between near and far
- Progressive dependence on reading glasses after 40
- High refractive errors that rule out LASIK or SMILE
- Thin corneas that make corneal laser surgery risky
- Dry eye disease that limits laser options
- Genuine dissatisfaction with contact lens wear, including intolerance, recurrent infections, or occupational impracticality
A detailed refractive and anatomical evaluation decides whether a presbyopic or phakic IOL is the right fit, or whether a different approach (LASIK, SMILE, or nothing at all) serves the patient better.
Presbyopic or Phakic IOL – Step-by-Step Procedure
- Comprehensive pre-operative workup: biometry, topography, endothelial assessment, anterior chamber depth, axial length, and macular imaging.
- Lens selection: power and model chosen based on measurements and visual goals.
- On the day of surgery: dilating and numbing drops instilled, eye draped in a sterile field.
- Small corneal incision created. For presbyopic IOLs, the natural lens is removed via phacoemulsification. For phakic IOLs, the natural lens stays in place.
- The chosen IOL is injected through the incision using a pre-loaded cartridge and positioned appropriately within the eye.
- Incision sealed, usually without sutures. Antibiotic and anti-inflammatory drops started.
- Patient reviewed the next day, at one week, and at regular intervals after that.
How Much Does Presbyopic and Phakic IOL Surgery Cost in India?
Cost depends on the lens type and brand, the technology platform used for measurement and implantation, the hospital category, and the city. Indicative ranges below.
| Procedure | Indicative Cost per Eye (INR) | Typical Inclusions |
|---|---|---|
| Multifocal IOL | 60,000 to 1,20,000 | Surgery, standard lens, post-op medications, first review |
| Trifocal IOL | 90,000 to 1,60,000 | Surgery, trifocal lens, follow-ups |
| EDOF IOL | 85,000 to 1,50,000 | Surgery, EDOF lens, follow-ups |
| Toric Presbyopic IOL | 1,00,000 to 1,80,000 | Surgery, toric presbyopic lens, astigmatic marking |
| Implantable Collamer Lens (ICL) | 80,000 to 1,50,000 | Surgery, ICL lens, pre-op YAG iridotomy if required |
| Iris-Fixated Phakic IOL | 90,000 to 1,60,000 | Surgery, lens, post-op care |
Final costs are confirmed after pre-operative evaluation, as lens power availability and additional investigations can shift the total.
Post-Surgery Care and Recovery
What to Expect After Surgery
Most patients see improved vision within 24 to 48 hours. Full neural adaptation to multifocal or EDOF lenses can take a few weeks to a few months. Mild grittiness, watering, and light sensitivity are normal in the first week. With phakic IOLs, vision often stabilises within a few days, because the natural lens is untouched and there is no capsular healing. Halos or glare around lights at night are common in the early weeks and usually fade with time.
Post-Operative Care Tips
- Use prescribed eye drops exactly on schedule.
- Do not rub or press on the eye.
- Keep direct water off the face for the first two weeks.
- Avoid swimming, contact sports, and dusty environments for at least four weeks.
- Protective sunglasses are helpful outdoors, given India’s strong sunlight.
- Resume driving only after your surgeon confirms adequate visual recovery, especially for night driving.
- Attend follow-ups at day 1, week 1, month 1, and month 3 to monitor intraocular pressure, lens position, and healing.

Frequently Asked Questions
Patients over 40 with presbyopia or cataract, healthy retinas, and realistic expectations about spectacle independence. The macula, corneal shape, pupil size, and tear film all need to cooperate. Screen all of these before committing to a lens. A great lens in the wrong eye produces an unhappy patient.
Yes. Unlike laser vision correction, phakic IOLs such as the ICL can be removed or exchanged if the refraction changes significantly or if complications arise. That reversibility is a quiet but genuine advantage, especially for younger patients whose eyes still have decades ahead of them.
Many patients achieve good spectacle independence for most daily tasks. Some still reach for reading glasses for very fine print or extended near work in dim light. “Zero glasses ever” is an overpromise; “far less glasses than before” is the realistic promise.
Each eye typically takes around 15 to 25 minutes. The total hospital visit is usually two to three hours, including preparation and post-operative observation.
Topical anaesthetic drops are used. Most patients report pressure or mild awareness rather than pain during surgery.
Same-day bilateral surgery is possible in selected cases but is usually staged by a few days to a week. Staging lets the surgeon assess the first eye’s response before committing to the second. In India, this cautious approach is standard practice.
LASIK reshapes the cornea using a laser. ICL places a lens inside the eye without altering corneal tissue. ICL is often preferred for thin corneas or very high refractive errors, where LASIK would either thin the cornea dangerously or leave too much residual error.
Presbyopic and phakic IOLs are designed to last a lifetime. Routine replacement is not expected unless complications arise.
Yes. If a cataract develops in later years, the phakic IOL can be removed and standard cataract surgery performed with a monofocal or premium IOL placed in the capsular bag. Having a phakic IOL does not close the door on future cataract surgery; it just adds an extra step.
Desk-based work can usually resume within three to five days. Jobs involving dust, physical exertion, or outdoor work may need one to two weeks off.
