目的 评价准分子激光角膜切削术 (PRK)后屈光回退再行准分子激光原位角膜磨镶术 (LASIK)的疗效。方法 对PRK术后≥ 1年 ,屈光回退但屈光度稳定的患者 9例 ( 15眼 ) ,行LASIK再次手术矫正 ,随访观察半年。结果 术中 2眼角膜瓣游离 ,但无其它严重并发症。 13眼术后 6月达到术前最佳矫正视力。屈光度 -1 0 0± 0 5 8D ,比第一次手术后平均降低 -4 2 5D。结论 PRK术后屈光回退行LASIK再手术是一种安全可行的方法 ,术后视力恢复快 ,屈光稳定。
Objective To evaluate the effect of laser in situ keratomileusis (LASIK) after refractive laser photorefractive keratectomy (PRK). Methods Nine patients (15 eyes) with PRR ≥1 years after refractive surgery and with stable refractive power were retrospectively treated with LASIK and followed up for six months. Results 2 cases of intraoperative corneal flap free, but no other serious complications. 13 eyes reached the best corrected visual acuity before surgery in June. Diopter -100 ± 0 5 8D, lower than the average after the first surgery -425D. Conclusion PRK postoperative refractive retroversion LASIK re-operation is a safe and feasible method, postoperative recovery of visual acuity, refractive stability.
