What is Vitreo-Retinal Surgery?
Vitreo-Retinal Surgery is a specialized procedure used to treat diseases affecting the vitreous (gel inside the eye) and the retina. It is performed to manage conditions like retinal detachment, macular holes, and diabetic retinopathy to preserve or restore vision.
Vitreo-Retinal Surgery in India
The back of the eye is not a simple place to work. The retina is tissue-paper thin. The vitreous gel that fills the cavity in front of it has to be removed carefully, because it is attached to the retina in ways that can pull the retina apart if you are clumsy. The working space is a few millimetres across. Instruments go in through ports smaller than a grain of rice.
Vitreo-retinal surgery is the sub-specialty that handles this territory. It covers the surgical and medical management of conditions affecting the vitreous gel and the retina at the back of the eye. A vitreo-retinal surgeon treats retinal detachment, vitreous haemorrhage, diabetic retinopathy complications, macular hole, epiretinal membrane, age-related macular degeneration, retinal vein occlusion, ocular trauma, and intraocular tumours.
At Vasan Eye Care, vitreo-retinal services are led by fellowship-trained specialists equipped with modern diagnostic and surgical platforms: optical coherence tomography (OCT), ultra-wide-field imaging, fluorescein and indocyanine green angiography, and small-gauge vitrectomy systems. The goal is to preserve or restore as much vision as possible through timely, evidence-based intervention. Timely is the word that matters most. Retinal emergencies do not reward patience.
The demand for vitreo-retinal care in India has expanded sharply in recent decades. The reasons are not mysterious: a growing diabetic population, an ageing demographic, and a high prevalence of myopia. Public health estimates suggest that diabetic retinopathy alone affects millions of Indians, while age-related macular degeneration and retinal detachment add further to the national burden of visual impairment.
Indian vitreo-retinal surgeons follow protocols set by the Vitreo-Retinal Society of India and international bodies such as the American Academy of Ophthalmology. Comprehensive diagnostic workup precedes every surgical decision, and the shift toward small-gauge (23-, 25-, and 27-gauge) vitrectomy over the past two decades has been quietly transformative: procedures are less invasive, healing is faster, and post-operative discomfort is significantly reduced compared with the older, larger-gauge systems.

Vitreo-Retinal Surgery: How the Procedure Works?
The workhorse of most vitreo-retinal surgery is pars plana vitrectomy. Three small ports are placed through the pars plana, a safe zone of the eye wall sitting behind the lens and in front of the retina. That spot is chosen because it avoids both critical structures.
Through these ports, the surgeon introduces a cutter to remove the vitreous, a light pipe to illuminate the field, and an infusion cannula to keep the eye pressurised. Additional tools (forceps, scissors, laser probes, silicone oil or gas injection cannulas) are introduced as the case requires. Depending on the pathology, the surgeon may peel retinal membranes, drain subretinal fluid, apply endolaser, or fill the vitreous cavity with gas or silicone oil to support retinal healing.
External procedures like scleral buckling involve placing a silicone band around the outside of the eye to support retinal reattachment from the outside in. Many complex cases combine both approaches.
When Is Vitreo-Retinal Surgery Necessary? Signs to Watch For
Seek vitreo-retinal evaluation when visual symptoms suggest a retinal or vitreous problem:
- A sudden shower of floaters
- Flashes of light in the peripheral vision
- A dark curtain moving across the field of view
- Distortion of straight lines
- Reduced central vision
- Sudden loss of vision
Patients with diabetes, high myopia, prior ocular surgery, trauma history, or a family history of retinal disease should undergo regular dilated retinal examinations, symptomatic or not. Surgical intervention is considered for structural retinal disease that cannot be adequately managed with medication or laser alone. Not every retinal condition needs surgery; picking the ones that do is what the subspecialty is for.
Vitreo-Retinal Surgery: Step-by-Step Procedure
- Evaluation with dilated fundus examination and imaging: OCT, fundus photography, ultra-wide-field imaging, angiography where indicated.
- Pre-operative counselling covering diagnosis, surgical plan, expected outcomes, and risks.
- On the day of surgery: anaesthesia (local or general) administered, eye prepared.
- Three small ports placed through the pars plana.
- Planned procedure performed, which may include vitrectomy, membrane peeling, retinal reattachment, laser, and tamponade.
- Ports closed and medications administered.
- Patient observed and discharged once stable.
- Specific head positioning explained when gas or oil tamponade has been used, and a follow-up schedule set.
How Much Does Vitreo-Retinal Surgery Cost in India?
Cost varies substantially with procedure type, tamponade, and hospital category.
| Procedure | Indicative Cost (INR) | Typical Inclusions |
|---|---|---|
| Pars Plana Vitrectomy (basic) | 60,000 to 1,20,000 | Surgery, consumables, follow-ups |
| Vitrectomy with Gas | 65,000 to 1,30,000 | Surgery, gas, post-op care |
| Vitrectomy with Silicone Oil | 80,000 to 1,50,000 | Surgery, silicone oil, subsequent removal |
| Scleral Buckling | 45,000 to 90,000 | Buckle placement and follow-ups |
| Pneumatic Retinopexy | 20,000 to 45,000 | Procedure and post-op care |
| Intravitreal Injection | 8,000 to 45,000 per injection | Drug, procedure, follow-up |
| Complex Trauma Surgery | 80,000 to 1,80,000 | Combined procedures, inpatient care |
Final pricing is confirmed after diagnostic assessment.
Post-Surgery Care and Recovery
What to Expect After Vitreo-Retinal Surgery?
The operated eye is usually patched for a day and reassessed the following morning. Vision is commonly blurred for days to weeks after vitrectomy, particularly when gas tamponade has been used. Mild ache, redness, and grittiness in the initial recovery are normal. Vision improves as healing progresses, and the final outcome depends heavily on the underlying condition and how long it was present before surgery. An eye brought in within 24 hours of a fresh macula-on detachment recovers very differently from an eye brought in two weeks after the same event.
Post-Operative Care Tips
- Follow positioning instructions strictly when gas or oil tamponade has been used. Positioning is part of the treatment, not a suggestion.
- Use prescribed drops on schedule.
- Avoid heavy lifting, straining, and vigorous exercise for three to four weeks.
- Do not fly while gas remains in the eye. Altitude-related expansion can cause dangerous IOP spikes.
- Avoid swimming and dusty environments for four to six weeks.
- Attend follow-ups to monitor intraocular pressure, retinal status, and healing. Medications may need adjusting.

Frequently Asked Questions
Retina specialists manage medical retinal conditions using drops, injections, and laser. Vitreo-retinal surgeons additionally perform surgical procedures such as vitrectomy and scleral buckling. In a busy clinic, the same doctor often wears both hats, but the distinction matters when a surgical referral is being made.
The surgery itself is performed under local or general anaesthesia and is not painful. Mild discomfort in the first few days of recovery is normal and is managed with simple analgesia.
Initial healing takes one to two weeks. Visual recovery varies from a few weeks to several months, depending on the underlying condition and any tamponade used.
Visual outcomes depend on the pre-operative state of the retina and macula. Early intervention generally produces better results. An eye with a macula-on detachment treated promptly can return to near-normal vision. One with chronic macular involvement will not.
When a gas bubble is used, face-down positioning keeps the bubble resting against the treated area so it can do its work. Skip the positioning and the tamponade does not deliver the pressure where you need it.
No, not while intraocular gas is still present. Gas expands at altitude and can cause a dangerous IOP spike. Once the gas has fully absorbed, confirmed by the surgeon, flying is safe again.
Typically day one, one week, one month, and then at intervals decided by the surgeon based on the condition. Some retinal conditions need lifelong periodic review, particularly in eyes with proliferative vitreoretinopathy or chronic diabetic retinopathy.
Retinal detachment (especially when the macula is still attached), vitreous haemorrhage, and ocular trauma typically need prompt referral, ideally within 24 to 48 hours. Waiting a weekend to see if symptoms settle is a bad bet with retinal problems.
Regular retinal evaluation picks up diabetic retinopathy and macular oedema early, when they are still treatable with laser or injections. Left alone, the same conditions can progress to tractional retinal detachment and severe vision loss that becomes much harder to reverse. Early care is cheaper, simpler, and far more effective.
Desk-based work can generally resume in one to two weeks. Heavy physical jobs may require four to six weeks off, as advised by the surgeon.
