准分子激光原位角膜磨镶术治疗中度远视的临床观察

LASIK for moderate hyperopia

目的观察准分子激光原位角膜磨镶术(excimer laser in situ keratomileusis,LASIK)治疗中度远视的安全性及有效性。方法对8例(16只眼)中度远视患者行LASIK。术前远视度数为+3.50～+6.00D,平均为(+5.18±1.00)D。术后随访观察12个月以上。结果术中无严重并发症,术后最佳矫正视力与术前相比,未见视力下降超过1行以上者。术后3个月时,屈光度基本稳定;术后1年时,平均远视度数为(+1.52±1.23)D,屈光度在0～+1.00D者占68.7%(11/16);平均裸眼远视力为0.65±0.23,其中≥0.5者15只眼(93.7%)。结论LASIK对于中度远视治疗具有良好的安全性及有效性,但疗效不及近视。

Objective To evaluate safety and efficacy of excimer laser in situ keratomileusis （LASIK） for moderate hyperopia. Methods LASIK was performed on 16 eyes of 8 patients using the Schwind Esiris excimer laser. The range of preoperative spherical equivalent was ＋3.50 - ＋6.00 D, and the average was （＋5.18＋ 1.00） D. All the cases were followed up for 12 months or longer. Results There was no serious complication during the operation. No eye lost more than 1 line of the best corrected visual acurity alter surgery. At 12 months, the mean postoperative spherical equivalent was （＋1.52±1.23）D. 68.7% of eyes reached 0 to ＋1.00 diopter. 93.7% of eyes achieved an uncorrected far vision of ≥0.5. Conclusion The LASIK is a safe and effective technique for the treatment of moderate hyperopia. But its effect is not better than that of myopia.
