Implication

Prospective study reveals superior visual and refractive outcomes for low-to-moderate versus high myopia after photorefractive keratectomy, suggesting high myopia may require multistep treatment.

Key Points

To evaluate the 1-year visual and refractive outcomes of single-step excimer laser photorefractive keratectomy across mild, moderate, and high myopia.
Prospective evaluation of 202 consecutive myopic eyes followed for over 1 year after undergoing 193-nm excimer laser photorefractive keratectomy.
Eyes were stratified into Group I (135 eyes, myopia < -7.00 D) and Group II (67 eyes, myopia -7.25 D to -13.50 D) using a single-step ablation program set to a maximum correction of -6.00 D.
Uncorrected visual acuity of 20/25 or better occurred in 89.6% of eyes in Group I versus 47.8% of eyes in Group II at 1 year.
Achieved refractive correction remained within ±1.00 D of target in 91.4% of Group I eyes compared with 51.7% of Group II eyes, with a mean manifest refraction reduction of 6.84 D in Group II.
Best spectacle-corrected visual acuity was equal to or better than baseline in 93.8% of all eyes, and corneal haze cleared in most eyes by 1 year.
