| Abstract |
|
To evaluate the effect of capsular tension ring on prevention of capsular opening reduction induced by CCC in Phacoemulsification with silicone intraocular lens implantation, we prospectively studied 60 patients (60 eyes)who were operated from Sept, 1997 to Jun, 1998 at our hospital.All patients had standardized Phacoemulsification, continuous curvilinear capsulorhexis, and intraocular lens implantation performed by the same surgeon.Patients were randomized into two groups based on capsular tension ring insertion.We compared uncorrected visual acuity (UCVA), spherical equivalent (SE), astigmatism and the data obtained by the Anterior Eye Segment Analysis System (EAS-1000), anterior chamber depth, IOL tilting, decenteration, and anterior capsule opening area at 1 week and 1, 3, 6 months after surgery.Two groups showed a similar pattern of change of UCVA, SE and astigmatism. There are no statistical significances in comparison of anterior chamber depth and IOL decenteration in two groups, but IOL tilting of group II is greater than that of group I at 6 months after surgery.The mean anterior capsular opening area at 1, 3, 6 months postoperatively was smaller than that of 1 week in two groups, but no statistical significances were observed in group II (1, 3, 6 months, P = or > .05).The mean percentage reduction of group I was significantly smaller than that of group II at 3 and 6 months (P<.05)after surgery.Capsular tension ring might prevent a contraction of capsular opening and might enhance the stability of IOL. |
