Phakic anterior chamber lenses is one of the modalities used to correct high myopia. We report the initial results of our prospective study on the Worst myopia claw intraocular lens (IOL) that is fixated to the anterior iris.
We studied 35 eyes in 18 patients with a preoperative myopia ranging from -6.00 to -28.00 diopters (D). The follow up ranged from 6 months (n = 15) to 12 months (n = 20).
In 26 (74.3%) eyes, the postoperative spherical equivalent refractive error was within 1.00 D of emmetropia. The mean refraction was stable between 1 to 2 months and 12 months. The mean spectacle-corrected visual acuity improved from 20/50 to 20/40. The straylight measurements did not show a significant increase postoperatively (p = .64). The mean endothelial cell loss was 5.6% (range, +6.3% to -22.6%) at 6 months, and 8.9% (range, +0.77% to -23.5%) at 12 months. We did not encounter major complications.
Implanting a Worst myopia claw IOL in high myopic eyes resulted in a stable, reasonably accurate refractive outcome. This group of patients will be followed longer because of concern over ocular complications with this technique.
有晶状体眼前房人工晶状体是用于矫正高度近视的方法之一。我们报告了关于固定于虹膜前部的最差近视爪状人工晶状体（IOL）的前瞻性研究的初步结果。
我们研究了18例患者的35只眼，术前近视度数范围为-6.00至-28.00屈光度（D）。随访时间从6个月（n = 15）至12个月（n = 20）。
26只眼（74.3%）术后等效球镜屈光不正度数在正视眼的±1.00 D范围内。平均屈光度数在1至2个月与12个月之间保持稳定。平均矫正视力从20/50提高到20/40。术后杂散光测量结果显示无显著增加（p = 0.64）。6个月时平均内皮细胞损失率为5.6%（范围为+6.3%至-22.6%），12个月时为8.9%（范围为+0.77%至-23.5%）。我们未遇到严重并发症。
在高度近视眼中植入最差近视爪状IOL可获得稳定且相当准确的屈光结果。由于担心该技术会引发眼部并发症，这组患者将接受更长时间的随访。
