To compare the outcomes of anterior chamber and retropupillary implantation of iris-claw Artisan intraocular lenses (IOL).
Prospective, randomized, single-blinded study.
Forty eyes of forty aphakic patients were enrolled. Patients were randomized into two groups. Each group includes twenty patients. Group 1 received anterior chamber Artisan IOL implantation. Group 2 received retropupillary Artisan IOL implantation. Preoperative and postoperative corrected distance visual acuity (CDVA), intraocular pressure (IOP), and all complications were noted and compared at 6 months follow-up.
Each two groups obtained a significant improvement in CDVA (P < 0.05). Four patients in Group 1 and five patients in Group 2 had significant but nonpermanent increase at IOP values. There were one and two pupillary irregularity in Group 1 and Group 2, respectively. In one patient, a shallow and inferior located retinal detachment were encountered in anterior chamber group.
The results were not significantly different between the two fixation techniques for iris-claw lens. The surgery procedure is dependent to surgeon experience and eye's conditions.
比较虹膜爪型Artisan人工晶状体（IOL）前房植入和瞳孔后植入的效果。
前瞻性、随机、单盲研究。
纳入40例无晶状体患者的40只眼。患者被随机分为两组。每组包括20例患者。第1组接受前房Artisan IOL植入。第2组接受瞳孔后Artisan IOL植入。记录术前和术后矫正远视力（CDVA）、眼压（IOP），并在6个月随访时比较所有并发症。
两组的CDVA均有显著改善（P < 0.05）。第1组4例患者和第2组5例患者的IOP值有显著但非永久性升高。第1组和第2组分别有1例和2例瞳孔不规则。在前房组的1例患者中，出现了浅且位于下方的视网膜脱离。
两种虹膜爪型晶状体固定技术的结果无显著差异。手术操作取决于外科医生的经验和眼部情况。
