PURPOSE: To compare the clinical outcomes, mainly including contrast sensitivity and high-order aberrations (HOAs), between wavefront-optimized (WFO) and corneal wavefront-guided (CWFG) transepithelial photorefractive keratectomy (transPRK) for preoperative HOAs >0.35 μm.
SETTING: Qingdao Eye Hospital of Shandong First Medical University, Qingdao, Shandong, China.
DESIGN: Prospective randomized controlled study.
METHODS: 71 patients with preoperative total ocular and corneal aberrations >0.35 μm who underwent transPRK for the treatment of myopia and myopic astigmatism were randomly divided into the aberration optimization mode group (WFO group; 36 eyes) and the corneal wavefront-guided mode group (CWFG group; 35 eyes). Preoperative and postoperative visual outcome, refraction, contrast sensitivity, and HOAs were compared.
RESULTS: 71 patients (71 eyes) who underwent transPRK were selected. The CWFG group had significantly lower total HOAs and coma values in the corneal aberration compared with the WFO group at 3 ( P = .009; P < .001) and 6 months postoperatively ( P = .006; P < .001). In addition, the CWFG group had significantly lower total HOAs and coma values in the whole-eye aberration compared with the WFO group at 3 ( P = .044; P = .004) and 6 months postoperatively ( P = .026; P = .001). The CWFG group had significantly better improvement in contrast sensitivity than the WFO group at spatial frequencies of 3 cycles per degree (cpd), 6 cpd, 12 cpd, and 18 cpd ( P = .005, P = .007, P = .001, and P < .001, respectively).
CONCLUSIONS: CWFG transPRK is associated with better visual and refractive outcomes and less HOAs than WFO transPRK in eyes with preoperative aberrations >0.35 μm.
