ANKARA, Turkey — Corneal topography after scleral buckling demonstrated transient changes that produced both myopia and corneal astigmatism, according to a study.
Researchers here prospectively studied 21 eyes of 21 patients with retinal detachment who underwent scleral buckling surgery. Corneal topography was measured before surgery and at 1 week and 1 and 6 months postoperatively.
A statistically significant central corneal steepening was noted 1 week after surgery. Total and irregular astigmatic components both revealed a significant but transient increase in the first postop month. The topographic changes persisted for as long as 6 months but returned to preoperative values afterward.
The study is published in Cornea.
