Abstract

Purpose: : To determine if the final corneal thickness after endothelial keratoplasty such as DLEK or DSEK is correlated in any way to visual performance.

Methods: : 155 consecutive eyes without macula disease underwent DLEK surgery and had pachymetry recorded at 6 months post–op. The eyes were grouped according to visual acuity, and pachymetry was correlated between groups. Group I (20/20, 20/25, or 20/30) n=38, Group II (20/40 or 20/50) n=79, Group III (20/60, 20/70, or 20/80) n=30, and Group IV (20/100 or worse) n=8.

Results: : The average, standard deviation and range of pachymetry for each group are as follows: Group I: 0.571±0.08 (0.408 to 0.784), Group II: 0.598±0.08 (0.437 to 0.816), Group III: 0.605±0.099 (0.454 to 0.945), Group IV: 0.607±0.12 (0.410 to 0.781) There was no significant correlation between vision and corneal thickness. (P>0.05) There was no statistical difference in pachymetry between all 4 groups. (P=0.323).

Conclusions: : The variance in corneal thickness in DLEK does not seem to influence visual results. The intentionally thickened cornea after DSEK may be optically acceptable.
