Vitrectomy: Microsurgery to Save and Restore Vision
Vitrectomy is one of the most versatile procedures in ophthalmology — used to treat everything from retinal detachment to diabetic bleeding. Here's what it involves.
What Is a Vitrectomy?
Vitrectomy is a microsurgical procedure that removes the vitreous — the clear, gel-like substance filling the middle of the eye — to give the surgeon direct access to the retina. It's one of the most common procedures used to treat serious retinal and vitreous conditions.
Conditions Treated With Vitrectomy
- Retinal detachment, especially complex or recurrent cases
- Vitreous hemorrhage (bleeding into the eye), often from diabetic retinopathy
- Macular hole or epiretinal membrane
- Severe eye infections or trauma involving the back of the eye
- Dislocated intraocular lens after cataract surgery

How the Procedure Works
- Tiny incisions (often less than 1mm) are made in the white of the eye.
- Micro-instruments remove the vitreous gel and any blood, scar tissue, or debris.
- The retina is repaired as needed — flattened, tears sealed with laser, or membranes peeled away.
- The eye is refilled with a saline solution, gas bubble, or silicone oil to help the retina heal in place.
Recovery
Vitrectomy is usually done as an outpatient or short-stay procedure under local anesthesia. If a gas bubble is used, specific head positioning may be needed for several days, and flying is restricted until it resolves — your surgeon will give exact instructions based on your case. Full visual recovery can take weeks to a few months.
Risks and Outlook
As with any intraocular surgery, risks include infection, bleeding, elevated eye pressure, and cataract formation over time (very common after vitrectomy in older patients). Despite these risks, vitrectomy has an excellent track record for stabilizing and often significantly improving vision in conditions that would otherwise lead to blindness.
