Indications for penetrating keratoplasty and associated procedures, 1996-2000

Cosar, C Banu; Sridhar, M S; Cohen, Elisabeth J; Held, Evan L; Alvim, Paulo de Tarso S; Rapuano, Christopher J; Raber, Irving M; Laibson, Peter R
PURPOSE: To identify current indications and trends in indications for penetrating keratoplasty and associated procedures. METHODS: Retrospective chart review of all patients who underwent penetrating keratoplasty at Wills Eye Hospital from January 1, 1996 to December 31, 2000. RESULTS: A total of 1,529 corneal transplants were performed during this 5-year period. The leading indications for penetrating keratoplasty were pseudophakic bullous keratopathy (PBK) in 416 (27.2%) cases, followed by regraft in 276 (18.1%), keratoconus in 236 (15.4%), and Fuchs endothelial dystrophy in 233 (15.2%) cases. Of the 416 PBK cases, 271 (65.1%) were associated with posterior chamber intraocular lenses (PC IOLs), 141 (33.9%) with anterior chamber intraocular lenses (AC IOLs), and four (1%) with iris-fixated lenses. Of these 141 AC IOLs, 107 (75.9%) were closed-loop and 34 (24.1%) were open-loop. Of the 416 PBK cases, in 281 (67.5%) cases, the IOL was not exchanged; in 127 (30.5%) cases, the IOL was exchanged; in six (1.5%) cases, the IOL was repositioned; and in two (0.5%) cases, the IOL was removed at the time of surgery. Of the 271 PC IOLs, 248 (91.5%) were not exchanged and 19 (7.1%) were exchanged. Of the 141 AC IOLs, 33 (23.4%) were not exchanged and 104 (73.7%) were exchanged (p = 0.001). CONCLUSIONS: Pseudophakic bullous keratopathy remains the leading indication for corneal transplantation at our institution followed by regraft. The percentage of PBK cases associated with PC IOLs has increased significantly, whereas the percentage associated with AC IOLs has decreased. The frequency of regraft has also increased significantly

Binocular vision recovery in bilateral keratoplasty

Sampaio, R; Held, E; Cohen, E J; Grewal, S; Rapuano, C J; Smith, A F; Laibson, P R
PURPOSE: To determine the benefit of bilateral penetrating keratoplasty with regard to binocular vision. METHODS: We compared patients who underwent corneal transplantation bilaterally with patients who had successful corneal transplantation in one eye and corneal disease in the other eye. Specifically, changes in fusion, stereopsis, and binocular vision function were analyzed. A questionnaire regarding performance of daily tasks was given. RESULTS: Patients with bilateral keratoplasty performed better in all the analyzed functions. Fusion was achieved by 81.25% in the unilateral group versus 100% in the bilateral group (p = 0.15). Stereopsis was present more in the bilateral group (100% vs. 62.5%, p = 0.008) and the quantity of stereopsis was significantly better in the bilateral group (121 seconds of arc vs. 1,284 seconds of arc, p = 0.014). 88.8% of the patients subjectively improved in daily activities after second eye surgery. CONCLUSION: There are objective and subjective improvements after bilateral penetrating keratoplasty
