白内障超声乳化吸除与囊外摘除人工晶体植入术后前房角对比观察

目的：对比观察巩膜隧道切口白内障超声乳化吸除折叠式人工晶体植入术和常规白内障囊外摘除人工晶体植入术后前房角对比情况。方法：采用Ｇｏｌｄｍａｎｎ房角镜分别观察３６眼巩膜隧道切口白内障超声乳化吸除折叠式人工晶体植入术和常规白内障囊外摘除人工晶体植入术后切口的变化、周边虹膜改变、晶体袢固定等情况。结果：白内障超声乳化吸除折叠式人工晶体植入术组及常规白内障囊外摘除人工晶体植入术组术后切口后弹力层脱离分别为

Observation of Anterior Chamber Angle after Phacoemulsification and Extra Capsule Cataract Extraction and Intraocular Lens Implantation

OBJECTIVE: To observe and compare the difference of anterior chamber angle after Phacoemulsification and Intraocular Lens Implantation (Phaco & IOL) through a tunnel incision and Extra Capsule Cataract Extraction and Intraocular Lens Implantation (ECCE & IOL). METHODS: The changes of internal incision, the peripheral iris and the fixation of lens intracapsular of 36 eyes were individually observed after the operation. RESULTS: Desemet's membrane detachments occurred in three eyes (8.35%) in the group of Phaco & IOL and four eyes (11.1%) in the group of ECCE & IOL. The difference was not significant. (P > 0.05) Peripheral anterior synechiae occured in three eyes (8.35%) of Phaco & IOL group and in 17 eyes (47.27%) of ECCE & IOL group. The difference was significant (P < 0.05). Intracapsular lens account for 31 eyes (86.1%) of Phaco & IOL group and ten eyes (22.5%) in ECCE & IOL group. The difference was statistically significant. (P < 0.05) CONCLUSION: Phaco & IOL can decrease the incidence of peripheral iris anterior synechiae and increase the chance of intracapsular placement of IOL.
