Study of corneal topographic patterns with single continuous suturing techniques in penetrating keratoplasty

Abstract

Purpose. To study the corneal topographic patterns following three different types of single continuous suturing techniques in penetrating keratoplasty. Methods. One hundred forty-eight maps obtained from 40 patients who underwent penetrating keratoplasty with single continuous suturing were retrospectively analyzed at a tertiary eye care center. The videokeratograph maps were obtained on the Eye Sys System 2000 at 1, 3, and 6 months after surgery. Suture adjustment was done for cases with astigmatism greater than 3 diopters, and maps were also obtained after suture adjustment. The maps were classified according to the corneal profile and the astigmatic pattern seen in the topographic maps. ..
