Cataract formation following corneal transplantation in eyes with Fuchs' endothelial dystrophy.

In a retrospective analysis, 78 eyes in 58 patients that underwent corneal transplantation for Fuchs' endothelial dystrophy were examined for the presence of cataracts. Follow-up ranged from 1 to 17 years, with an average of 6.62 years. Thirty-four (44.1%) of the eyes developed cataracts sufficient enough to require surgical removal. The mean time from transplant to cataract formation averaged 4.9 years. The average age at the time of transplant surgery in the eyes that did not develop cataracts was 55.6, and in those that developed cataracts, 60.3 (p = 0.049). Thirteen percent of the transplants lost transparency following cataract extraction. The incidence of postkeratoplasty cataract increased at age 50 and occurred in 75% of eyes grafted in patients 60 years of age or older.
