摘要：目的：介绍我们使用ReLEx（（R））flex（ReLEx）治疗中高度近视的初步临床经验。我们比较了ReLEx与飞秒激光原位角膜磨镶术（FS-LASIK）的疗效、安全性和角膜高阶像差。方法：ReLEx的前瞻性研究与FS-LASIK的回顾性研究相比较。ReLEx是一种新的角膜屈光手术，通过飞秒激光切割基质层并手动取出。40例患者双眼均接受ReLEx治疗。回顾性确定了41例FS-LASIK患者的可比组。结果：ReLEx组术前视力平均为-7.50 ± 1.16D，FS-LASIK组术前视力平均为-7.32 ± 1.09D。对于所有眼睛，两组的平均矫正远视力保持不变。对于以正视眼为目标屈光度的眼睛，41%的ReLEx和61%的FS-LASIK眼睛的裸眼远视力为logMAR
Abstract.Purpose: To present our initial clinical experience with ReLEx((R)) flex (ReLEx) for moderate to high myopia. We compare efficacy, safety and corneal higher-order aberrations after ReLEx with femtosecond laser in situ keratomileusis (FS-LASIK).Methods: Prospective study of ReLEx compared with a retrospective study of FS-LASIK. ReLEx is a new keratorefractive procedure, where a stromal lenticule is cut by a femtosecond laser and manually extracted. Forty patients were treated with ReLEx on both eyes. A comparable group of 41 FS-LASIK patients were retrospectively identified. Visual acuity, spherical equivalent (SE) and corneal tomography were measured before and 3 months after surgery.Results: Preoperative SE averaged -7.50 +/- 1.16 D (ReLEx) and -7.32 +/- 1.09 D (FS-LASIK). For all eyes, mean corrected distance visual acuity remained unchanged in both groups. For eyes with emmetropia as target refraction, 41% of ReLEx and 61% of FS-LASIK eyes had an uncorrected distance visual acuity of logMAR
