# What is keratoprosthesis?

A keratoprosthesis is an artificial corneal device implanted to restore vision when standard corneal transplantation has failed or is unlikely to succeed. It replaces the central cornea with a clear optical cylinder supported by a surrounding carrier.

## Indications

Severe ocular surface disease, multiple graft failures, chemical burns, or certain congenital conditions may lead to consideration of keratoprosthesis. Careful selection is vital because surgery and aftercare are demanding.

- Devices typically combine a clear optical core with a donor corneal or synthetic skirt
- Some designs require lifelong bandage contact lens wear
- Risk of complications such as glaucoma, retinal detachment, or infection is significant
- Patients need intensive, long‑term follow‑up in specialised centres

## Visual Outcomes

Keratoprostheses can provide dramatic visual improvement in otherwise blind eyes, but vision can fluctuate and complications may limit longevity. Lifelong commitment to care is essential.

- Topical antibiotics and other drops are usually required indefinitely
- Regular imaging monitors optic, retina, and optic nerve status
- Failure may necessitate device revision or removal
- Multidisciplinary support helps manage associated glaucoma and surface problems
