目的：评价单片式Acrysof人工晶体在白内障超声乳化植入术中术后的表现。方法：在2002年3月至11月期间，196眼白内障行超声乳化及AcrySof　SA60AT单片式人工晶体植入，评价其可折叠性、可控性、植入的难易度、人工晶体的居中性、术中术后并发症、术后视力、后发障等。结果：在所有病例中，人工晶体容易折叠，可控性好，通过小切口可以顺利植入，袢角展开缓慢，对囊袋不产生损伤，人工晶体居中性好，术后视力恢复好，最佳矫正视力≥0.5，无一例发生后发障。结论：单片式AcrySof人工晶体具有良好的生物相容性，袢的柔韧性和张力，及在囊袋内的稳定性。

The preliminary report of single-piece AcrySof IOL implantation
ABSTRACT
PURPOSE: To evaluate the intraoperative and postoperative performance of the single-piece AcrySof SA60AT intraocular lens (IOL) in a series of patients after cataract surgery and IOL implantation. METHODS: In this prospective study, 196 cases who had phacoemulsification and implantation of a single-piece AcrySof SA60AT lens from March to Nov. 2002 were evaluated. Assessed were control of IOL folding, ease of IOL implantation, IOL centration, intraoperative and postoperative complications, visual acuity, and anterior(ACO) and posterior (PCO) capsule opacification. RESULTS: In all cases, the IOL was easily folded, inserted, and unfolded. It remained well centered in the capsular bag, and there were no intraoperative or postoperative complications. The best corrected visual acuity after surgery was 0.5 or better in all patients. CONCLUSIONS: Initial results indicate that the single-piece AcrySof SA60AT IOL has good biocompatibility, haptic flexibility and resistance, and stability in the capsular bag.
Key words: single-piece AcrySof IOL, phacoemulsification, IOL implantation.
