Background:Retreatments are sometimes necessary to correct residual or induced refractive errors following refractive surgery.Many different combinations of primary treatment methods and retreatment techniques have been studied,however,few studies have investigated wavefront-optimized(WFO)technology for retreatment following primary refractive surgery.This study aimed to report the outcomes of WFO photorefractive keratectomy(PRK)retreatments of refractive error following previous laser refractive surgery with PRK,laser in situ keratomileusis(LASIK),or laser-assisted subepithelial keratectomy(LASEK).Methods:We reviewed records of patients who underwent WFO PRK retreatments using the Allegretto Wave Eye-Q 400 Hz Excimer Laser System(Alcon Surgical)between January 2008 and April 2011 at Walter Reed Army Medical Center and Madigan Army Medical Center.Outcomes were recorded in terms of uncorrected distance visual acuity(UDVA),manifest refraction spherical equivalent(MRSE),corrected distance visual acuity(CDVA),and complications at 1 month(M),3 M,and 6 M post-op.Results:Seventy-eight patients(120 eyes)underwent WFO PRK retreatment during the study period.Primary surgery was surface ablation in 87 eyes(78 PRK,9 LASEK)and LASIK in 33 eyes.The mean spherical equivalent before retreatment was−0.79±0.94 D(−3.00 to 1.88 D).UDVA was≥20/20 in 69 eyes(60.0%)at 1 M,54 eyes(71.1%)at 3 M,and 27 eyes(73.0%)at 6 M follow-up.MRSE was within±0.50 D of emmetropia in 78 eyes(67.8%)at 1 M,59 eyes(77.6%)at 3 M,and 25 eyes(67.6%)at 6 M follow-up.CDVA was maintained within±1 line of pre-op in 113 of 115 eyes(98.3%)at 1 M,74 of 76 eyes(97.4%)at 3 M,and 37 eyes(100%)at 6 M follow-up.Conclusion:Although follow-up was limited beyond 3 M,WFO PRK retreatments in patients with residual refractive error may be a safe and effective procedure.Further studies are necessary to determine the long-term safety and stability of outcomes. 展开更多
