The annual American Society of Cataract and Refractive Surgery (ASCRS) meeting took place in April. It was preceded by the World Cornea Congress, as it is approximately every 4 years. This is a packed, 2-day meeting, specifically focused on the cornea.
What really struck me was that the emphasis has shifted very strongly toward surgery, both in terms of surgical techniques and complications, much more than in the past.
We now have many different types of keratoplasty, and many of those involve new techniques as well as instrumentation. At the same time, it raises new questions about how to still obtain the best possible results.
One of the more interesting developments is that we have moved away from full-thickness transplant to retention of Descemet membrane and endothelium. But we are now also seeing rejection at the stromal levels, particularly with keratocytes. We will need more study about how to control that problem so that we can obtain the same benefits we have had in the past. So there is much more to come on that.
We are going to have some very interesting years ahead as we explore these different techniques available to us and learn how to maximize the benefits to our patients.
