To examine postoperative positional stability of myopic phakic intraocular lenses (IOLs).
Prospective, nonrandomized clinical study.
The study included 46 eyes which received an anterior chamber angle-supported (Bausch & Lomb NuVita; 10 eyes), anterior chamber iris-fixated (Ophtec Artisan; 20 eyes) or ciliary sulcus-implanted phakic IOL (Staar ICL; 16 eyes). The distance between the phakic IOL and the crystalline lens and the cornea as well as rotation around the optical axis was evaluated using Scheimpflug photography at 1, 3 to 6, and 12 months postsurgery.
The anterior chamber phakic IOLs showed no significant movement in anteroposterior direction. The posterior chamber phakic IOL showed a significant movement toward the crystalline lens between postoperative months 3 and 12. The median amount of rotation around the optical axis between the 3- and the 12-month evaluation was 1.9 degrees (range = 0.0-33.5 degrees) for the NuVita, 0.6 degrees (range = 0.0-3.5 degrees) for the Artisan, and 0.9 degrees (range = 0.2-2.3 degrees) for the ICL. Four NuVita IOLs rotated more than 10 degrees.
The angle-supported anterior chamber phakic IOLs showed a generally stable position regarding distance to cornea and natural lens, but rotation was observed in four IOLs. The iris-fixated phakic IOL showed the highest overall stability. The posterior chamber phakic IOL was stable in terms of rotation but had a tendency to decrease in distance toward the crystalline lens. Intraocular lenses implanted in phakic eyes followed for 12 months demonstrate stable IOL position overall.
研究近视有晶状体眼人工晶状体（IOL）术后的位置稳定性。
前瞻性、非随机临床研究。
该研究纳入了46只接受前房角支撑型（博士伦NuVita；10只眼）、前房虹膜固定型（Ophtec Artisan；20只眼）或睫状沟植入型有晶状体眼IOL（STAAR ICL；16只眼）的眼睛。在术后1个月、3至6个月以及12个月时，使用Scheimpflug摄影评估有晶状体眼IOL与晶状体及角膜之间的距离以及围绕光轴的旋转情况。
前房有晶状体眼IOL在前后方向上无明显移动。后房有晶状体眼IOL在术后3至12个月期间向晶状体有明显移动。在3个月和12个月评估之间，NuVita围绕光轴旋转的中位数为1.9度（范围=0.0 - 33.5度），Artisan为0.6度（范围=0.0 - 3.5度），ICL为0.9度（范围=0.2 - 2.3度）。4只NuVita IOL旋转超过10度。
角支撑型前房有晶状体眼IOL在与角膜和自然晶状体的距离方面位置总体稳定，但有4只IOL出现了旋转。虹膜固定型有晶状体眼IOL总体稳定性最高。后房有晶状体眼IOL在旋转方面稳定，但与晶状体的距离有减小趋势。随访12个月的有晶状体眼植入的IOL总体显示位置稳定。
