目的探讨运用以角膜地形图角膜波前像差引导的最优个性化角膜屈光矫正程序(OptimizedRefractiveKeratectomyORK)治疗各种角膜屈光性手术后,包括放射状角膜切开术(RadialKeratotomyRK)、准分子激光屈光性角膜切削术(PhotorefractioKeratectomyPRK)及准分子激光原位角膜磨镶术(LaserinsituKeratomileusisLASIK)后屈光过矫、欠矫或回退的疗效。方法运用角膜地形图角膜波前像差引导ORK程序及小光斑高速飞点激光扫描系统对38例(57只眼)多种角膜屈光手术后屈光回退、欠矫、过矫等患者行再次激光手术。术后随访6-18个月,观察视力及屈光状态。结果38例57眼手术顺利,全部术眼术后裸眼视力≥0.6,即57眼(100%);≥1.049眼(85.96%);57眼屈光度均少于±1.0D,无严重并发症。结论角膜地形图角膜波前像差引导(ORK)程序矫治RK、PRK、LASIK术后的屈光回退安全有效,但需深入研究和严格掌握适应症。
Objective To investigate the optimal corneal refractive index-guided optimal personalized corneal refractive correction (Corneal Topography Keratosis) after corneal refractive surgery, including radial keratotomy (Radial KeratotomyRK), excimer laser flexion Photorefractive keratectomy (PRK) and excimer laser in situ keratomileusis (KeratomileusisLASIK) after refractive overcorrection, undercorrection or regression of the curative effect. Methods 38 patients (57 eyes) with multiple corneal refractive corneal refractive surgery, undercorrection and overcorrection were performed with corneal topography and corneal wavefront guided ORK program and small spot high-speed flying laser scanning system Laser surgery again. After 6-18 months of follow-up, visual acuity and refractive status were observed. Results 38 cases (57 eyes) were operated successfully. The visual acuity of uncorrected visual acuity was ≥0.6, that is 57 eyes (100%), ≥1.049 eyes (85.96%). The refractive power of 57 eyes was less than ± 1.0D. No serious complication occurred. Conclusion corneal topography Keratosis wavefront guided correction (ORK) program correction of RK, PRK, LASIK refractive regression safe and effective, but in-depth study and strict indications.
