Abstract

Purpose : To identify if and how preoperative visual acuity predicts visual acuity outcomes after DMEK.

Methods : 1000 consecutive patients having undergone pseudophacic DMEK or Triple-DMEK from the prospective Cologne DMEK database were analyzed for correlations between pre- and postoperative visual acuity values at 1, 3, 6, and 12 months after transplantation. Analysis was done using Latex textprocessing combined with R statistical analysis (www.r-project.org).

Results : There is a significant correlation between pre- and postoperative visual acuity (VA) after (Triple)-DMEK. Preoperative VA below 20/80 leads to delayed and reduced final visual acuity results after 12 months, whereas VA between 20/80 and 20/40 just take longer to reach good final VA values, which are reached faster for preoperative VA values above 20/40. There is only a mild predictive value of preoperative corneal thickness on postoperative VA. There is no significant differences for preoperative VA values above 20/40. The chance to reached postoperative VA above 20/25 is 40% for preoperative VA of 20/200, 50% for preoperative VA of 20/60 and > 60% for preoperative VA of 20/40.

Conclusions : DMEK results in very good final postoperative visual acuity results even in eyes with bad preoperative vision due to corneal pathology. However, below preoperative acuity values of 20/80 recovery is significantly poorer and delayed. This suggests to operate early enough to achieve good final visual acuity results. Preoperative visual acuity seems to be a good predictor for final outcome.
