If I am not suitable for PTK then is there an alternative?

There are a couple of alternatives to PTK. These are a cornea transplant and manual scraping.

A cornea transplant is where the surgeon replaces the damaged part of the cornea (in the centre) with a clear, healthy cornea. This new cornea is obtained from a local eye bank. This procedure may be required to restore normal, focusing power to your eyes.

Cornea transplants are often referred to as PK – ‘Penetrating Keratoplasty’.

Manual or cornea scraping is the process in which the surgeon removes or scrapes away the damaged or diseased part of the cornea. For example, if a patient has a corneal ulcer.
