To assess the efficacy and safety of laser in situ keratomileusis (LASIK) for correction of myopic refractive errors in eyes which have previously undergone retinal detachment surgery.
In a prospective, non-comparative case series, 10 eyes of nine patients who had a myopic refractive error and had previously undergone retinal detachment surgery underwent LASIK surgery according to the standard surgical protocol. The surgery could be completed in eight eyes and in two eyes it was aborted intraoperatively. The parameters evaluated included the uncorrected visual acuity, best corrected visual acuity, refraction, detailed fundus evaluation with indirect ophthalmoscope, slit lamp biomicroscopy, and corneal pachymetry. Any intraoperative or postoperative complications were recorded. Follow up visits were scheduled at day 1, 1 week, 1 month, 3 months, and 6 months after LASIK.
Eight eyes underwent successful LASIK surgery. The mean spherical equivalent before surgery was -5.436 (SD 1.6) dioptres (D), which was reduced to +0.42 (0.65) D, -0.07 (1.32) D, -0.06 (1.39) D, and -0.06 (0.65) at 1 week, 1 month, 3 months, and 6 months respectively after LASIK. The uncorrected visual acuity improved in all the eyes and the best corrected visual acuity improved or remained same in all the eyes. There was no retinal complication after LASIK.
LASIK may be used to correct refractive errors in eyes that have undergone retinal detachment surgery. However, scarred conjunctiva in such cases may prevent generation of optimal suction for the microkeratome.
评估准分子原位角膜磨镶术(LASIK)矫正既往接受过视网膜脱离手术的眼睛近视屈光不正的疗效和安全性。
在一项前瞻性、非对照病例系列研究中,9例患有近视屈光不正且既往接受过视网膜脱离手术的患者的10只眼睛按照标准手术方案接受了LASIK手术。8只眼睛的手术得以完成,2只眼睛在术中中止。评估的参数包括裸眼视力、最佳矫正视力、验光、使用间接检眼镜进行详细的眼底评估、裂隙灯生物显微镜检查和角膜测厚。记录任何术中或术后并发症。在LASIK术后第1天、1周、1个月、3个月和6个月安排随访。
8只眼睛成功接受了LASIK手术。术前平均等效球镜度为-5.436(标准差1.6)屈光度(D),在LASIK术后1周、1个月、3个月和6个月分别降至+0.42(0.65)D、-0.07(1.32)D、-0.06(1.39)D和-0.06(0.65)D。所有眼睛的裸眼视力均有提高,所有眼睛的最佳矫正视力均有提高或保持不变。LASIK术后未出现视网膜并发症。
LASIK可用于矫正既往接受过视网膜脱离手术的眼睛的屈光不正。然而,此类病例中结膜瘢痕可能会妨碍微型角膜刀产生最佳负压。
