准分子激光原位角膜磨镶术治疗远视眼

Treating hyperopia with laser in situ keratomileusis

目的 :评价LASIK治疗远视眼的有效性、可预测性和安全性。方法 :用LASIK治疗 54只远视眼 ,屈光度 +1 0 0～ +6 0 0D ,术后平均随访一年。对裸眼和矫正视力、屈光稳定性和并发症等进行了分析。结果 :至术后一年时 ,平均残余屈光度为 +0 2 9± 0 78D ,屈光度在± 0 5D和± 1 0D以内者分别占 61 1 % ( 33只眼 )和 83 3% ( 45只眼 )。裸眼视力达到 0 5以上者占 92 6% ( 50只眼 ) ,1 0以上者 63 0 % ( 34只眼 )。 1只眼 ( 1 9% )最佳矫正视力下降 2行 ,2只眼 ( 3 7% )增加 2行。 2只眼 ( 3 7% )有眩光。结论 :LASIK可用于治疗 +1 0 0～ +6 0 0D的远视眼且具有较好的预测性和安全性。

HT5”SS][WT5”BZ][ST5”BZ]Objective:To evaluate the effectiveness,predictability and safety of LASIK in treating hyperopia.Methods:54 eyes of 35 patients with hyperopia ranging from +1 00 D to +6 00 D were treated with LASIK.The average follow up was one year.Data on uncorrected and best corrected visual acuity,stability of refraction,and complications were analyzed.Results:At one year postoperatively,the average residual refraction was +0 29±0 78 D.The number of eyes between ±0 5 D and ±1 0 D were 33 eyes (61 1%) and 45 eyes (83 3%) respectively.The number of eyes of uncorrected visual acuity of 0 5 and 1 0 were 50 eyes (92 6%) and 34 eyes (63 0%) respectively.One eye (1 9%) lost 2 lines of the best corrected visual acuity and two eyes(3 7%) increased 2 lines or more.Two eyes(3 7%) had halos.Conclusions:LASIK can be used to treat +1 0 D to +6 0 D hyperopia with good predictability and safety.Some modification of the surgical algorithms and laser nomogram is helpful to improve the predictability and stability of surgery.
