January 2013 plasty is indeed the future, or just a fad. Society. None of the doctors have financial interests related to their lectures. The thinner the better? Standing on the shoulders of giants In the evolution of keratoplasty, there has been a rapid transition from PK to endothelial keratoplasty (EK), said Edward J. Holland, M.D., Cincinnati. EK has achieved broader acceptance by having had its early disadvantages of an increased rate of primary donor failure and endothelial cell loss mostly addressed, but current disadvantages include visual outcomes that are still not on par with cataract surgery, and endothelial cell loss remains higher than would be ideal. In other words, said Dr. Holland, EK is "doing better, but not as well as we would like." The procedure continues to evolve, and one direction the procedure is headed toward is using thinner tissues. There used to be a bias toward thicker tissue that was easier to manage, but surgeons have since found that thinner tissue results in better visual acuity. What's more, the development of donor insertion devices such as the Busin Glide (Moria, Antony, France) and Tan EndoGlide (Angiotech, Vancouver, B.C.) have made thin tissues more manageable. The next trend, said Dr. Holland, is Descemet's membrane EK (DMEK), which eliminates stroma from donor tissue to create the thinnest donor tissue possible. However, donor preparation is even more difficult, there is an increase in endothelial cell loss, and there is the risk of rebubbling. In the future, he said, new methods for donor preparation need to be developed, and prospective studies need to compare DMEK with thin EK to establish the true value of the procedure. EW MEETING REPORTER "Expanding the Realm of the Possible," Richard L. Abbott, M.D., Mill Valley, Calif., delivered a lecture on "Corneal transplantation: The quest for perfection through innovation." Innovation, said Dr. Abbott, is "to make a change in something Celebrating the meeting's theme of established," distinguished from invention in that it hinges upon a knowledge of prior methods and technology.
