You might want to know what an eye looks like before and after corneal transplantation for keratoconus. Keratoconus is a hereditary condition where the cornea gets thinner and steeper. This results in high astigmatism and blurred vision. If you have keratoconus, you have probably heard that you may need a corneal transplant at some time in your life. There are treatments such as corneal collagen cross linking that can help to avoid corneal transplant but sometimes the thinning and steepening is too advanced for this to work. Anterior lamellar keratoplasty (ALK or DALK) which is a partial thickness transplant can be a much better option than a full thickness transplant (PKP). These photos show what the cornea looks like before and after corneal transplant (ALK) for keratoconus. The vision and ability to fit a contact lens is much better after ALK.
