Keratoconus is a very frustrating disease with visual disability often requiring a corneal transplant when vision degrades to where glasses or contacts don’t work well. CTAK corneal tissue addition provides a great option for those patients with quick recovery, improved vision without the long recovery or risk of a corneal transplant. We’ve been very happy with the results.

It’s pretty quick and easy! Overall I think CTAK is a fantastic procedure for patients with keratoconus that markedly improves uncorrected and best corrected vision without need for a more invasive PK or DALK
