Cornea Surgery<br />
Corneal transplant surgeons at the <strong>Cole</strong> <strong>Eye</strong> <strong>Institute</strong> perform state-of-the-art transplants for<br />
numerous conditions that distort or cloud this normally transparent tissue. The traditional<br />
full-thickness procedure, known as penetrating keratoplasty (PK), makes up the bulk of<br />
grafts that are performed in our institution. From January 2006 through September 2007,<br />
137 PKs were performed, with 95.6 percent of these grafts remaining clear at three<br />
months.<br />
<strong>Cole</strong> <strong>Eye</strong> corneal transplant surgeons have also embarked on cutting-edge lamellar<br />
corneal transplant procedures in which only the portion of the cornea that is diseased is<br />
replaced. Using a procedure called descemet stripping automated endothelial keratoplasty<br />
(DSAEK), surgeons may now selectively transplant the endothelium for conditions such<br />
as pseudophakic bullous keratopathy and Fuchs endothelial dystrophy. Recipients of this<br />
procedure are provided faster visual recovery and more stable and predictable refractive<br />
outcomes than with traditional PK. During the above-mentioned period, 45 DSAEKs were<br />
performed, with 100 percent of the grafts remaining clear at three months.<br />
Corneal surgeons are also transplanting just the anterior portion of the cornea for conditions<br />
such as keratoconus and corneal scarring. This procedure, deep anterior lamellar<br />
keratoplasty (DALK), affords the advantage of allowing patients to retain their own healthy<br />
endothelium, avoiding the risk of endothelial rejection and other potential complications<br />
associated with PK. Over the past two years, 23 DALKs were performed, with 100 percent<br />
of the grafts remaining clear at three months.<br />
