作者最近在一组包括正常和青光眼的患者中观察到白内障囊外摘出术和硬性Galand盘状人工晶体植入后随访一年的后囊混浊发生率为22%,而在一组104眼植入Sinskey型J袢人工晶体随访2年的后囊混浊率仅17%。植入Galand盘状人工晶体术后平均11个月,有13%的病例需做YAG囊切开,而植入Sins-key型J袢人工晶体后平均21个月,需作YAG囊切开的只有10%。作者曾推测盘状晶体表面与囊壁接触面大,向囊四周伸展较多,可能会抑制囊袋上皮细胞的增殖与迁移,而事实与作者的估计相反。在本研究中,作者评估了一组植入硬性Galand盘状人工晶体的裂隙灯表现和视力结果。对象和方法:本组为1984年3月至1988年3月间由同一医生做的20例白内障囊外摘出术
The authors recently observed a posterior capsular opacification rate of 22% at one year of follow-up in a group of patients with normal and glaucoma including extracapsular cataract extraction and hard Galand discoidal intraocular lens implantation, while in a group of 104 eyes implanted Sinskey J 袢 intraocular lens follow-up 2 years of posterior capsule opacification rate of only 17%. Implantation of Galand intraocular lens after an average of 11 months, 13% of cases need YAG capsulotomy, and implantation of Sins-key J 袢 intraocular lens after an average of 21 months, to be YAG capsulotomy Only 10%. The authors have speculated that the surface of the disc-shaped crystal and the contact surface of the capsule large, extending around the capsule more likely to inhibit the proliferation and migration of the bladder epithelial cells, and the fact that contrary to the author’s estimate. In this study, the authors evaluated the slit lamp performance and visual acuity of a group of implants implanted with rigid Galand intraocular lenses. Subjects and Methods: This group was performed by the same doctor between March 1984 and March 1988, 20 cases of extracapsular cataract extraction
