目的：评价固体激光光学角膜切削术治疗高度近视的疗效。方法：应用Ｌｉｇｈｔ ＢｌａｄｅＴＭⅡ固体激光手术系统进行光学角膜切削术治疗高度近视－６．１２～－１６．００Ｄ１０６ 例１８０ 眼，随访１２ ～２４ 月，回顾性评价疗效和并发症。结果：１８０ 眼术前平均球镜屈光度－８．１９±０ ．５３Ｄ，术后１ 年－ ０．４７ ±０．４２Ｄ。术前平均角膜屈光力４３ ．２４ ±０ ．２６Ｄ，术后３９ ．８９ ±０ ．５０Ｄ。在１２ 个月时，试矫和实矫屈光度相差０ ．５０Ｄ内５８ ．９５ ％ ，１ ．００Ｄ内９３．３３％ ，２．００Ｄ内９８ ．３３％ 。术后１ 年裸视力１ ．０ 占５７．２２％ ，裸视力０ ．５ 占９５％ ，最好矫正视力达到术前水平８０％ ，超过１ 行６ ．６７ ％ ，超过２ 行３．３３％ ，下降１ 行８．８９％ ，下降２ 行１．１１ ％ 。术后角膜Ⅰ级ｈａｚｅ１ ，３，６，１２ 月分别是５２ ．２２ ％ ，４２ ．７８ ％ ，４５ ％ ，４５ ．５６ ％ ，Ⅱ级ｈａｚｅ 分别是１９ ．４４ ％ 、１５ ％ 、１２ ．７８ ％ 、８ ．３３ ％ ，Ⅲ级ｈａｚｅ１ 眼０ ．５６％ 。１０ 眼屈光回退６～１７ 月再手术。４ 眼激素性眼压升高，用药后恢复。结论：固体激光治疗高度近视安全有效，
Objective: To evaluate the efficacy of solid laser optical keratotomy in the treatment of high myopia. Methods: The light blade TM Ⅱ solid laser surgery system was used to treat 180 cases of high myopia (-6.12 ~ -16.00D106 cases), followed up for 12-24 months. The curative effect and complication were retrospectively evaluated. Results: 180 preoperative average spherical refraction -8.19 ± 0. 53D, 1 year after surgery - 0.47 ± 0.42D. Preoperative average corneal refractive power 43. 24 ± 0. 26D, postoperative 39. 89 ± 0. 50D. At 12 months, there was a difference of 0 between trial and actual refraction. Within 95%, 1. 93.33% within 00D, 98 within 2.00D. 33%. 1 year postoperative visual acuity 1. 0 accounted for 57.22%, naked vision 0. 5 accounted for 95%, the best corrected visual acuity reached preoperative level of 80%, more than 1 line 6. 67%, 3.33% over 2 lines, down 8.89% from 1 line, down 1.11% from 2 lines. Postoperative corneal grade I haze1,3,6,12 were 52. 22%, 42. 78%, 45%, 45. 56%, level II haze respectively 19. 44%, 15%, 12. 78%, 8. 33%, grade haze1 eye 0. 56%. 10 eyes refraction 6 to 17 months and then surgery. 4 eye hormonal intraocular pressure increased after treatment. Conclusion: Solid laser treatment of high myopia is safe and effective,
