Laser in situ keratomileusis outcomes following radial keratotomy, astigmatic keratotomy, photorefractive keratectomy, and penetrating keratoplasty

“…1,2 The Prospective Evaluation of Radial Keratotomy study 3 reports that 25% to 30% of patients who were treated with RK were hyperopic 10 years after treatment and as many as 43% of post-RK patients had a hyperopic shift of 1.00 diopter (D) or more.…”

Treatment of Low, Moderate, and High Myopia With the 193-nm Excimer Laser*

“…In a more recent study that more accurately reflects the way radial keratotomy is performed today, at the last postoperative visit 20/25 or better uncorrected visual acuity was achieved in 86% of patients (23). Thirty-three percent of these patients required enhancement procedures to attain these results.…”
