Outcome of penetrating keratoplasty in patients with bilateral corneal blindness

Abstract

Purpose: To evaluate the outcome of penetrating keratoplasty in patients with bilateral corneal blindness. Methods: Bilaterally blind patients who had undergone optical penetrating keratoplasty (PK) were evaluated on optical and refractive parameters and presence of complications if any. The results at 3 months, 6 months, and 1 year were compared with age-matched and indication-matched unilaterally blind controls. Results: The most common indication for surgery in both the groups was the presence of a corneoiridic scar. Best corrected visual acuity of ≥6/18 was seen in five (16.66%) patients in the study group and in 11 (36.66%) patients in the control group (P = 0.14). In all, 15 (50%) graf..
