机译：AIM:To evaluate postoperative pain,uncorrected visual acuity(UCVA),and cornea haze value after transepithelial photorefractive keratectomy(T-PRK) performed with aspherical ablation profile using SCHWIND ESIRIS excimer laser.· METHODS:Retrospective case series.Fifty-nine eyes(32 patients) with myopia associated with or without astigmatism underwent phototherapeutic keratectomy(PTK) followed by photorefractive keratectomy(PRK) which performed by Optimized Refractive Keratecomy(ORK)-CAM software based on aspherical ablation profile using SCHWIND ESIRIS excimer laser.Postoperative pain scale was measured on a questionnaire through five levels.Haze was graded by five grades,and UCVA,manifest refraction spherical equivalent(MRSE) were analyzed.· RESULTS:Mean pain level was(1.37±0.613)(range:1 to 3),the mean time picking out the soft contact lens was(6.22±1.73) days,at 3 months,UCVA was 1.0 for 40 eyes(67.8%),0.5 for all eyes(100.0%).The UCVA was significantly less than the preoperative best spectacle corrected visual acuity(BSCVA)(t =-2.84,P =0.006),haze value was(0.27±0.25),no patients had a haze grade up to 2.Mean MRSE was(0.76±0.96) diopter(D) by 3 months.· CONCLUSION:The outcomes from this study show that using the SCHWIND ESIRIS aspherical ablation profile for transepithelial PRK has a good visual result.The primary advantage is related to a spherical ablation profile,automatically considers the ablation volume of the stroma and the accurate and smooth removal of the epithelium with PTK.Additional studies are needed to determine long-term outcomes.
