Our main outcome measures were best-corrected visual acuity (BCVA) and contrast sensitivity over 24 months follow-up.Results Median age was 67 (60–73) years with 55% women (n=70) and majority Chinese (74%, n=94) in our Asian population. There were no significant differences between demographics between the FED (48%, 61 eyes) and BK (52%, 67 eyes) groups. Forward multivariate linear regression adjusted for age, gender, donor graft thickness and diagnosis (FED vs BK) revealed that preoperative visual acuity was the most significant factor associated with visual acuity at 1 year (B=0.032, p=0.03, R2=0.122). Visual recovery was longer in eyes with BK, with a significantly better visual acuity in the FED group at 12 months (mean logarithm of the minimum angle of resolution BCVA BK: 0.27±0.1 vs FED: 0.22±0.9; p=0.001), but not significant at 24 months (p=0.154). Contrast sensitivity significantly improved more in the first 6 months in the FED when compared with the BK group (at 3.0, 6.0 and 12.0 cycles per degree, p<0.01).Conclusions Our study suggests that while there was significant improvement in contrast sensitivity and visual acuity after DSAEK, poor preoperative visual acuity was associated with an inferior visual outcome and the time to recovery was longer in eyes with BK.
