If your surgeon does not consider you a suitable candidate for PTK, then you do have other options. One of these options is a cornea transplant, and the other is manual scraping.

A cornea transplant involves your surgeon removing the damaged part of your cornea and replacing it with a healthy cornea. It is sometimes referred to as a penetrating keratoplasty or PK. This cornea is human and is taken from an eye bank close to the clinic. The transplant is frequently done so your eye can regain the ability to focus efficiently.

Manual scraping (or cornea scraping) is a procedure encompassing your surgeon physically scraping away the section of a cornea that has been subjected to damage or disease. An example when manual scraping may be employed is if you have a corneal ulcer.
