PURPOSE: To compare @entity2790 ( @entity2790 ) with peripheral corneal relaxing incisions (PCRIs) for @entity940 correction in @entity1 undergoing @entity231 surgery. METHODS: 54 @entity1 (54 eyes) with more than 0.75 diopter (D) of preexisting corneal @entity940 were classified as group A (0.75-1.50D) or group B (1.75-2.50D). The @entity1 were randomized to undergo @entity2790 or PCRIs in the steep axis with @entity737 . LogMAR uncorrected visual acuity (LogMAR UCVA), LogMAR best corrected visual acuity (LogMAR BCVA), @entity2246 ( @entity2246 ), surgery induced refraction correction ( SIRC ), and correction rates (CR) were measured 1 month and 6 months postoperatively. RESULTS: At 6 months postoperatively, all 54 eyes had LogMAR BCVA  <= 0.2. @entity1 who underwent PCRIs and @entity2790 with LogMAR BCVA  <= 0.1 showed no significant differences in group A (P = 1.00) or in group B (P = 0.59). Group A showed no significant differences in LogMAR UCVA (P = 0.70),  @entity2246  (P = 0.13),  SIRC  (P = 0.71), and CR (P = 0.56) in @entity1 underwent PCRIs and @entity2790 . However, group B showed significant differences in LogMAR UCVA (P < 0.01),  @entity2246  (P < 0.01)),  SIRC  (P < 0.01), and CR (P < 0.01). The LogMAR UCVA and  @entity2246  between 1 and 6 months showed no significant differences in @entity1 in group A. However, in group B, they are significant differences. CONCLUSION: The efficacy and stability of @entity2790 and PCRIs were equal in low @entity940 @entity1 . @entity2790 achieved an enhanced effect over PCRIs in higher @entity940 @entity1 . PCRIs had the more refractive regression than @entity2790 in 6 months.
