Visual Outcomes after Penetrating Keratoplasty

A chart review of the hospital records of all patients who underwent penetrating keratoplasty at Maharaj Nakorn Chiang Mai Hospital between January 1996 – December 1999 was retrospectively performed. Out of total 45 corneal transplants, the best-corrected visual acuity of 6/6 to 6/12 was achieved in 8.9% (4 of 45), 6/18 to 6/36 in 22.2% (10 of 45), 6/60 to 1/60 in 44.5% (20 of 45). One (2.2%) patient could not be evaluated for visual acuity.
