目的：为了检查白内障手术后植入的硅橡胶和丙烯酸人工晶状体（IOL）的前后透镜囊何时完全与光学部对置，并确定不同IOL材料是否影响囊接触完成的时间。设计：随机对照临床试验。参与者：根据植入的IOL类型（硅胶或丙烯酸），使用随机数字表将计划接受白内障手术的70例患者的70只眼随机分配至两组。每组32例患者完成了随访。干预：所有的眼睛进行了超声乳化手术，植入硅或丙烯酸人工晶状体。所有IOL均准确置入囊袋中。主要结果测量：在术后3、5、7、9、11、14、21和28天，使用Scheimpflug视频摄影系统评价前、后透镜囊与IOL光学表面的接触。确定每个囊与IOL光学部完全对合的术后日期。结果：所有患者的前囊与人工晶状体光学部接触的时间均在同一天或早于后囊。在前囊（术后6.2天vs 3.6天; P < 0.0001）和后囊膜（术后11.1天vs 7.4天; P = 0.0339）中，观察到硅凝胶IOL的IOL完全贴壁明显早于丙烯酸IOL。平均前房深度没有显着变化，观察与硅凝胶IOL，而有显着的前移后植入的丙烯酸ILO.Conclusions：囊接触的IOL光学完成后约8天内白内障手术后，硅凝胶IOL和丙烯酸IOL 11天。硅凝胶IOL与前囊和后囊膜的完全贴壁明显早于丙烯酸IOL。(C)2002年，美国眼科学会。
Objective: To examine when the anterior and posterior lens capsule completely become apposed to optics of silicone and acrylic intraocular lenses (IOLs) implanted after cataract surgery and to determine whether the different IOL materials influence the timing of completion of capsular contact.Design: Randomized controlled clinical trial.Participants: Seventy eyes of 70 patients who were scheduled to undergo cataract surgery were randomly assigned to two groups using random number tables based on the type of IOL implanted: silicone or acrylic. Thirty-two patients in each group completed the follow-up.Intervention: All eyes underwent phacoemulsification surgery with implantation of either a silicone or acrylic IOL. All IOLs were accurately placed into the capsular bag.Main Outcome Measures: Contact of the anterior and posterior lens capsule with the IOL optic surface was evaluated using the Scheimpflug videophotography system at 3, 5, 7, 9, 11, 14, 21, and 28 days after surgery. The postoperative day at which each capsule was completely apposed to the IOL optic was determined. In addition, anterior chamber depth was also measured.Results: The anterior capsule was in contact with the IOL optic on the same day or earlier than the posterior capsule in all patients. Complete apposition of the IOL was observed significantly earlier with silicone IOLs than with acrylic IOLs with both the anterior capsule (6.2 versus 3.6 postoperative days; P < 0.0001) and the posterior capsule (11.1 versus 7.4 postoperative days; P = 0.0339). No significant change in mean anterior chamber depth was observed with the silicone IOL, whereas there was significant anterior shift after implantation of the acrylic IOL.Conclusions: Capsular contact with the IOL optic is completed within approximately 8 days after cataract surgery with silicone IOLs and 11 days with acrylic IOLs. Complete apposition to both the anterior and posterior capsule was significantly earlier with silicone IOLs than with acrylic IOLs. (C) 2002 by the American Academy of Ophthalmology.
