Frequently Asked Questions
The procedure itself is performed under anaesthesia, so the patient does not feel pain. Post-operative discomfort is managed with medication.
Full visual recovery and stabilisation can take up to a year or more, although initial healing occurs within weeks.
Penetrating Keratoplasty (PK) is a full-thickness cornea transplant. Descemet's Stripping Endothelial Keratoplasty (DSEK) is a partial transplant replacing only the back layers, leading to faster recovery.
Yes, if a graft fails, a repeat keratoplasty (or regraft) can be performed, though it may carry a higher risk of rejection.
