Popis: Purpose: Long-term quality of vision after Descemet stripping endothelial keratoplasty (DSEK) was evaluated and correlated with corneal characteristics and subjective complaints. Methods: Thirty-four eyes were examined; patients had a single visit 6 to 64 months after DSEK for Fuchs dystrophy. Best-corrected distance acuity (BCDA) and straylight were analyzed. To better evaluate long-term postoperative BCDA changes, longitudinal data were used from earlier visits. Corneal thickness was measured with the Visante anterior segment optical coherence tomography. Interface, stromal, and endothelial haze were semiquantitatively graded using the slit lamp. Vision-related quality of life was evaluated with the 39-item National Eye Institute Visual Function Questionnaire and a straylight questionnaire. Correlation analysis comparing corneal characteristics with visual quality was performed. Results: Mean postoperative time was 1027 +/- 453 days. Mean BCDA at this time was 0.33 +/- 0.19 logarithm of the minimal angle of resolution. BCDA remained stable with long-term postoperative follow-up. Straylight averaged 1.47 perpendicular to 0.19, on average 0.12 log units higher than normal for age-related pseudophakic eyes (P
