Changes of Anterior Chamber Angle and Intraocular Pressure after Implantation of Intraocular Lens through Small Incision in a Non-phacoemulsification Way
摘要
Abstract
Objective To explore the correlation between the anterior chamber angle and intraocular pressure after the implantation of intraocular lens ( iol) through small incision in a non - phacoemulsification way. Methods Totally 110 senile cataract patients admitted to our hospital in 2010 underwent implantation of iol with superficial anaesthesia through small incision. Among whom we chose 101 senile cataract patients ( 104 eyes ) as the research subjects whose operation process was smooth and the posterior capsulars remained complete and iol successfully being implanted into capsular bag. Relevant parameters of anterior chamber including anterior open distance at 500μm ( AOD500 ), trabeculum - tunica coerulea included angle ( TIA ), anterior chamber depth ( ACD ) were measured by ultrasonic biomicroscope ( UBM ) preoperatively. Intraocular pressures were measured by Goldmann ophthalmotonometer. All these parameters were re - measured by the same technician 2 weeks, 1 month, and 3 months postoperatively. Morphouses of the anterior chambers were recorded preoperatively and re - recorded 1 month postopera-tively through microgonioscope. Results Compared with the normal eyes, the intraocular pressure showed significant difference in these diseased eyes before surgery ( P < 0. 05 ). ACD, AOD 500, TIA, and intraocular pressure before surgery were also significantly different from thoese 2 weeks, 1 month, and 3 months after surgery ( P < 0. 05 ). In addition, AOD 500 and TIA had a negative correlation with intraocular pressure. Conclusion Small incision of non - phacoemulsification and intraocular lens ( iol) implantation might result in an enlargement of ACD and width of anterior chamber and a significant decrease of intraocular pressure. AOD500 and TIA are important factors that influence the intraocular pressure in the elderly.关键词
