Sequential transplant-cataract surgery yielded better refractive accuracy than simultaneous surgery

Sequential penetrating keratoplasty and phacoemulsification provided better refractive accuracy than the two surgeries performed simultaneously, a study found.

Ken Hayashi, MD, and Hideyuki Hayashi, MD, compared outcomes in 23 eyes of 23 patients undergoing sequential penetrating keratoplasty and phacoemulsification to outcomes in 39 eyes of 39 patients undergoing simultaneous procedures.

At a minimum 3 months' follow-up, patients in the simultaneous surgery group had significantly higher mean refractive errors compared to those in the sequential surgery group. Regular and irregular astigmatism did not significantly differ between groups, and both groups had similar endothelial cell loss.

At 12 months, 70% of sequential surgery patients and 39% of simultaneous surgery patients were within 2 D of intended refraction (P = .03).

The study is published in the October issue of Cornea.
