It is great that you are thinking about the long-term results of your laser vision correction. As you may already know, collagen cross-linking activates the collagen fibres within the cornea to cross-link and thus resulting in a stronger cornea. By strengthening the cornea after laser vision correction, it is hoped that the longevity of your laser results can be extended and at the same time, minimising the need of enhancement surgery in future.
Whilst cornea thickness does play an important part during a laser suitability evaluation, it is also important to note that it is not the only factor a surgeon will consider when recommending the need for collagen cross-linking. The surgeon will also look at other factors including the shape of the cornea and make the recommendation should he/she feels that there is some weakness in the cornea that may increase the probability of any degree from returning.
