Quick Overview

This surgery removes the gel-like vitreous inside the eye. It treats problems like retinal detachment, a macular hole, or vitreous haemorrhage. It’s done under local or general anaesthesia through tiny incisions, and most people go home the same day. Recovery time and positioning requirements depend on the condition being treated, the surgical procedure performed, and whether a gas bubble or silicone oil is used as an internal tamponade. 

• This surgery treats retinal detachment, macular holes, vitreous haemorrhage, and several other retinal conditions.
• Modern small-gauge techniques, including 23-, 25-, and 27-gauge vitrectomy, use smaller instruments and incisions that can often be left sutureless. 
• Some patients need face-down or other specific positioning after surgery, particularly when a gas bubble is used for macular hole or retinal detachment repair. The duration depends on the condition and surgical findings. 
• Cataract development is a common complication after vitrectomy, particularly in people over 50 who still have their natural lens.

If your ophthalmologist has recommended eye surgery, booking a retina specialist consultation is a good first step. Although the procedure may sound intimidating, modern vitrectomy is a well-established vitreoretinal surgery. It’s one of the most common retinal surgeries performed today. Depending on the underlying condition, vitrectomy can help preserve vision, repair structural damage, or prevent further vision loss. 

Vitrectomy is used for several vitreoretinal conditions, including retinal detachment, vitreous haemorrhage, macular holes, epiretinal membranes and other disorders affecting the retina or vitreous. In simple terms, the surgeon removes the vitreous gel filling the eye. The surgeon may replace the removed vitreous with balanced salt solution, air, gas, or silicone oil, depending on the condition being treated and the surgeon’s technique. 

This guide covers why the surgery is done and what happens on the day. It also walks through recovery week by week, the risks involved, and realistic costs in India.

What Is a Vitrectomy and Why Is It Done?

It’s surgery to remove the vitreous, the clear gel filling the back of the eye. Surgeons perform it either to reach the retina directly or to clear vitreous that’s clouded with blood or scar tissue. The procedure lets the surgeon access the retina and treat conditions such as retinal detachment, macular holes, scar tissue, or vitreous haemorrhage. Removing the vitreous can also relieve abnormal traction and create the surgical access needed to treat retinal and vitreous disorders. 

What is the meaning of vitrectomy, and why is the vitreous gel removed?

In standard pars plana vitrectomy, surgeons insert instruments through small openings in the pars plana, a region of the eye located behind the lens. The pars plana provides access to the vitreous cavity while allowing the surgeon to work away from the central retina and natural lens.

Removing the vitreous gel gives the surgeon a clear working space. It also relieves traction that can pull on or detach the retina. Relieving this traction can be an important part of treating conditions such as retinal detachment, macular hole and vitreomacular disorders. 

Which conditions need pars plana vitrectomy or vitreoretinal surgery?

Vitrectomy is commonly used to repair certain retinal detachments, particularly when the retinal condition or other surgical factors make vitrectomy appropriate. It may also be needed when membranes, scar tissue, vitreous traction or other changes prevent the retina from being treated adequately with less invasive approaches. 

It is also used to treat vitreous haemorrhage, which can occur with conditions such as proliferative diabetic retinopathy, retinal tears or other retinal disorders. Other reasons include a macular hole, an epiretinal membrane, or a dislocated lens fragment. Each indication changes how the surgery is planned and how long recovery takes.

What Happens During the Vitrectomy Procedure?

The procedure is performed in a controlled surgical setting, with the type of anaesthesia chosen based on the patient, procedure, and surgeon’s assessment. General anaesthesia may be used in children and in selected patients or procedures where local anaesthesia with sedation is not suitable. 

What anaesthesia is used, and what are the 23G, 25G and 27G microincision techniques?

Local anaesthesia numbs the eye and surrounding area, often with light sedation to help you relax throughout. Modern surgery uses microincision techniques such as 23-gauge, 25-gauge, or 27-gauge instruments.

A higher gauge number indicates a smaller instrument and usually a smaller surgical incision. Many small-gauge vitrectomy incisions can be left without sutures, depending on the case and surgical technique. Small-gauge techniques may reduce surgical trauma and can be associated with less postoperative discomfort and inflammation in some patients. Your surgeon will choose the gauge based on your specific anatomy and the complexity of the repair.

Why is the eye filled with gas, silicone oil or saline afterwards?

After the retinal problem has been treated, the surgeon may use air, a gas bubble or silicone oil to provide internal tamponade and support the retina while it heals. Gas bubbles are common for retinal detachment and macular hole repair, and the body absorbs them gradually over several weeks.

The choice of gas affects how long the process takes, from about two weeks to over a month. Silicone oil is often used in selected complex retinal cases and may require a separate removal procedure once the retina is stable. In other cases, the vitreous cavity may be left filled with a balanced salt solution or natural intraocular fluid when a long-lasting internal tamponade is not required.

What Is Vitrectomy Recovery Like, Week by Week?

Recovery varies by indication and by which tamponade was used. Still, a few patterns are common across most cases, regardless of why the surgery was needed.

What happens in the first 48 hours, and what will your vision look like?

Your eye will likely be patched or shielded at first, with some grittiness and mild discomfort. Your surgeon will prescribe postoperative eye drops, which may include anti-inflammatory or antibiotic medication depending on the procedure and your individual needs. If a gas bubble was used, vision may look hazy or bubble-obstructed, clearing gradually as the bubble shrinks. Blurred vision is common during early recovery, especially with a gas bubble, but report sudden or worsening vision loss to your surgeon promptly. 

How long does face-down posturing after vitrectomy last, and how do you manage it at home?

Specific head positioning may help keep the gas bubble against the treated area and may be recommended after macular hole or retinal detachment surgery. The duration can range from several days to longer periods, depending on the condition, type of surgery and surgeon’s instructions. Special pillows and face-down chairs make the position far more manageable at home.

When can you return to work, drive, travel and exercise?

Many people return to light, desk-based work within one to two weeks. Early activity levels affect healing, so follow your post-surgery care instructions closely.

Wait to drive until your vision and any gas bubbles have cleared enough, as confirmed by your surgeon. If a gas bubble is present, air travel and significant altitude changes are prohibited until the bubble has completely disappeared. Avoid strenuous activity for as long as your surgeon recommends. Swimming is usually off-limits too, until your surgeon clears you. The timing for returning to normal activities varies and should be based on your surgeon’s assessment and the type of surgery performed.

What Are the Side Effects, Risks and Complications of Vitrectomy?

This surgery is generally safe, but like any eye procedure, it carries some risks worth understanding beforehand. Seek prompt assessment if symptoms suggest a postoperative complication. 

Why can cataracts develop after vitrectomy? 

Vitrectomy is associated with an increased risk of cataract formation or progression, particularly in older adults who still have their natural lens. Timing varies from person to person and may depend on age, lens status, and other factors. If a significant cataract is already present or progression is a concern, the surgeon may discuss whether to perform cataract surgery at the same time. 

What are the risks of raised eye pressure, infection and retinal re-detachment?

Raised eye pressure can occur temporarily after surgery and is usually managed with eye drops. Infection, called endophthalmitis, is rare but serious, and needs urgent treatment if it happens.

Retinal re-detachment is also possible, particularly in complex cases. The risk of retinal complications varies with the underlying condition, retinal anatomy, previous surgery and other patient-specific factors. That’s why follow-up visits matter, even once your vision feels back to normal.

How Much Does Vitrectomy Surgery Cost in India?

Costs vary widely across India, depending on the hospital, the surgeon’s experience, and your specific case. Thinking in tiers helps more than chasing one fixed number. Follow-up visits and any additional procedures typically sit outside the initial quote too.

What changes the price, including tamponade choice and lens implants?

The choice of gas or silicone oil can affect the overall treatment cost, particularly if silicone oil removal or additional procedures are required later. Combining this surgery with cataract treatment and a lens implant also adds to the overall cost. When cataract surgery is clinically appropriate, combining it with vitrectomy may avoid the need for a separate cataract operation later. 

Because pricing depends so heavily on individual factors, costs vary by centre and case. For billing and insurance guidance, confirm exact pricing at your consultation.

Why is silicone oil removal a planned second surgery?

Silicone oil is often removed once the retina has stabilised, although in selected cases it may be left in the eye for longer or indefinitely. Once the retina has healed and stabilised, usually after a few months, it’s removed. Silicone oil removal is a separate procedure, and its complexity depends on the retina’s condition and any additional treatment required. Leaving the oil in longer than necessary raises the risk of complications like persistently raised eye pressure.

Conclusion: Deciding on Vitrectomy Surgery With Confidence

Vitrectomy is a well-established vitreoretinal procedure used to treat several conditions that can threaten vision. Vitrectomy surgery for a macular hole, retinal detachment, or vitreous haemorrhage each follows a different path. The goal stays the same throughout: protecting your vision.

The right approach, tamponade choice, and recovery plan depend entirely on what’s being treated. If your retina specialist has recommended this surgery, ask about your specific indication. Expected recovery and realistic outcomes are worth discussing too, before you decide.

Frequently Asked Questions

How successful is vitrectomy surgery?

Success depends heavily on what’s being treated. Published surgical outcome studies commonly report macular hole closure in roughly 90% or more of cases. Single-surgery retinal reattachment is in the 85 to 90% range, and higher with a second procedure if needed.

Vitreous haemorrhage clears in most patients, though visual recovery also depends on any underlying retinal damage from the original cause. Your surgeon can give you figures specific to your own diagnosis and eye history.

Can you fly after vitrectomy if you have a gas bubble?

No. Flying, or even travelling to high altitude, is unsafe while a gas bubble sits in your eye. The gas expands at lower pressure, which can dangerously spike eye pressure. Your surgeon will confirm once the bubble has fully resorbed and flying is safe again.

Is vitrectomy surgery painful?

Not during the procedure itself, thanks to anaesthesia. Afterwards, most people report mild grittiness or soreness rather than sharp pain. This is usually manageable with prescribed drops and settles within a few days.

Will your vision be fully restored after vitrectomy?

Not always. The surgery treats the structural problem, but your final vision also depends on any pre-existing damage. Many patients see significant improvement, though full restoration isn’t guaranteed in every case. Your retina specialist can give you a realistic sense of what to expect based on your specific diagnosis.
