Objective: The main advantage of posterior lamellar keratoplasty (PLK) is that the technique induces little postoperative astigmatism and minimizes suture-related complications. The current retrospective report describes early results concerning satisfaction of patients who underwent Descemet’s stripping and automated endothelial keratoplasty (DSAEK) between July und December 2006 at the University Eye Hospital Erlangen.
Methods: 10 eyes of 10 patients (5 w, mean age 74 year; 5 m, mean age 70 years) in whom a DSAEK was performed for Fuchs endothelial dystrophy (n=9) or PEX-keratopathy (n=1) were evaluated. Data within this report were utilized from a postoperative evaluation period between 12 days and 5 month. Patient satisfaction was evaluated based on a questionnaire.
Results: In 2 eyes, the posterior donor disk did not attach to the recipient posterior stroma, so in one case the operation was repeated and in the other case a penetrating keratoplasty was performed in a secondary procedure. One patient developed an Urrets-Zavalia syndrome. Mean postoperative thickness of the posterior lamellar disc was 204 µm and thickness of the recipient posterior stroma was 591 µm. Mean preoperative astigmatism was 1,2±0,5 D changing to 1,8±0,8 D postoperative (based on corneal topography). Using a scale from 1 (poor) to 10 (highly satisfied) mean grading was 6 (min. 3, max. 10). Focusing only on successful operations mean grading increased to 8 (min. 4, max. 10).
Conclusions: PLK was largely accepted by patients who underwent this procedure. After successful operation an increase in visual acuity was observed already within the short observation period accompanied only by a small postoperative shift in refractive astigmatism.
