Vitrectomy
A vitrectomy is a type of eye surgery performed to remove the vitreous humor, the clear, gel-like substance that fills the inside of the eye. This procedure is done to treat a variety of retinal and vitreous disorders, often to improve vision or prevent further vision loss.
Why is Vitrectomy Performed
Vitrectomy may be recommended for:
- Retinal detachment
- Macular hole
- Epiretinal membrane (macular pucker)
- Vitreous haemorrhage (bleeding into the vitreous)
- Infections (endophthalmitis)
- Severe eye trauma
- Complications of diabetic retinopathy, such as proliferative changes
- Removal of floaters (rarely, if they severely affect vision)
What to expect on the day of Surgery
- Anaesthesia: Local (numbing the eye) or general anaesthesia may be used.
- Incisions: Tiny incisions (usually less than 1 mm) are made in the white part of the eye (sclera).
- Removal: A small instrument is inserted to remove the vitreous gel.
- Treatment of underlying issue: The surgeon may repair the retina, remove scar tissue, seal tears, or apply laser treatment.
- Replacement fluid: The vitreous may be replaced with:
- Saline solution
- Gas bubble (e.g., SF6 or C3F8)
- Silicone oil (for long-term support)
Recovery Time
- Initial recovery: A few days to 2 weeks.
- Full recovery: Several weeks to months depending on the procedure.
