What Is Vitrectomy?
The vitreous is the gel-like substance filling the space between your lens and retina. A vitrectomy removes this gel and replaces it with saline, a gas bubble, or silicone oil — giving the surgeon clear access to repair issues like retinal detachment, macular holes and intraocular bleeding.
Symptoms that may need vitrectomy
Conditions It Treats
Retinal Detachment
The retina separates from the back of the eye, potentially causing permanent vision loss if untreated.
Macular Hole
A small break in the macula causing blurred or distorted central vision.
Vitreous Haemorrhage
Bleeding into the vitreous gel, often related to diabetic retinopathy or trauma.
Epiretinal Membrane
Scar tissue on the retina's surface causing vision distortion.
Advanced Diabetic Eye Disease
Fragile blood vessels that can bleed or pull on the retina.
Severe Infection or Trauma
Conditions like endophthalmitis requiring removal of damaged tissue.
The Procedure, Step by Step
- 1
Tiny Incisions
Openings usually less than a millimetre in size are made in the sclera.
- 2
Vitreous Removal
Specialised instruments remove the clouded or blood-filled vitreous gel.
- 3
Retinal Repair
Tears are sealed with laser or cryotherapy, or scar tissue is carefully peeled away.
- 4
Vitreous Replacement
The space is filled with saline, a gas bubble, or silicone oil depending on your case.
- 5
Closure
The small incisions typically close naturally without stitches.
Concerned about a retinal condition?
Early assessment makes a real difference to your treatment options and outcome.
Recovery
Mild discomfort, redness and blurred vision are normal in the first few days, managed with prescribed antibiotic and steroid drops. If your eye was filled with a gas bubble, you may need to keep your head positioned face-down for days to weeks, and avoid flying until it's fully dissolved. Silicone oil stays longer and often needs a separate removal procedure later. Vision improvement can take several weeks to months, depending on how the retina heals.
Success Rates
85–90%
Single-surgery success for retinal detachment
90%+
Closure success for macular holes
80–90%

Some patients may not regain full clarity, particularly if retinal damage was severe before surgery — but modern microsurgical techniques have made vitrectomy safer and more effective than ever.
Conclusion
Vitrectomy is a sight-saving operation for serious retinal conditions, with high success rates and a well-understood recovery process. If you've been told you need one, understanding what to expect at each stage makes the experience far less daunting.
Frequently Asked Questions
No — surgery is typically performed on one eye at a time to reduce complication risk and allow proper monitoring. The second eye, if needed, is usually scheduled weeks later.
