The purpose of this clinical study was to evaluate refraction, best visual acuity and anterior chamber flare after implantation of a Worst Iris Claw Lens to correct high myopia.
From September 1996 to February 1999 the implantation of a Worst Iris Claw lens was performed on 44 highly myopic phakic eyes of 28 patients. Data after 6 weeks and 6 months follow-up were assessed.
The mean preoperative spherical equivalent was--17.35 +/- 3.57 dpt and 6 months after implantation 79% of the eyes were within +/- 1.0 dpt of target refraction. The mean best corrected visual acuity increased from 0.43 preoperatively to 0.65 postoperatively and 6 months after the treatment there was no flare (< 10 photons/ms) in 21% and a mild anterior chamber flare (10-80 photons/ms) in 76% of the treated eyes. The median laser flare was 20 p/ms.
In conclusion, implantation of a Worst Iris Claw lens has proved to be a precise method to correct high myopia. No or mild anterior chamber flare and a good visual acuity were measured in most eyes 6 weeks and 6 months after surgery. Longer follow-up periods are needed to assess the long-term safety and efficiency.
本临床研究旨在评估植入 Worst 虹膜爪形人工晶状体矫正高度近视后的屈光状态、最佳视力和前房闪光情况。
1996年9月至1999年2月，对28例患者的44只高度近视有晶状体眼实施了 Worst 虹膜爪形人工晶状体植入术。评估了术后6周和6个月的随访数据。
术前平均等效球镜度为-17.35±3.57屈光度，植入后6个月，79%的术眼屈光度数在目标屈光度±1.0屈光度范围内。最佳矫正视力平均从术前的0.43提高到术后的0.65，治疗后6个月，21%的术眼无前房闪光（<10光子/毫秒），76%的术眼前房有轻度闪光（10-80光子/毫秒）。激光闪光中位数为20光子/毫秒。
总之，植入 Worst 虹膜爪形人工晶状体已被证明是矫正高度近视的一种精确方法。术后6周和6个月时，大多数术眼无前房闪光或仅有轻度闪光，且视力良好。需要更长的随访期来评估长期安全性和有效性。
