The Study To Prevent The Posterior Capsule Opacification After The Posterior Capsule Polishing And Completely Viscoelastics Sucking

Purpose: The aim of this study is to test that wethear cataract phacoemulsification andlens implantation intraoperative, posterior capsular polishing and completelyviscoelastics sucking can prevent posterior capsular opacification (PCO). This maybeprovide important infromation to clinical surgical techniques.Methods: The patients of this study were selected from January2011to December2011in our hospital. The subjects of the study were inciluded173cases of senile cataractsurgery patients (243eyes)，85male patients (124eyes) and88female patients (119eyes). All patients underwent preoperative visual acuity was light perception to0.4. Theage of the patients range from50to79years, the average age was67.97±6.71years.The patients were randomly divided into three groups. Group A (control group)was treated with conventional phacoemulsification technique, no capsular polishing, nosucking viscoelastics behind the IOL. Group B (polished group) was treated capsularpolishing after conventional phacoemulsification technology and sucking viscoelasticsbehind the IOL. Group C (polishing group+sucking viscoelastics behind the IOL) wastreated with conventional phacoemulsification technology and intraoperative capsularpolishing, completely sucking viscoelastics behind the IOL group. The patients of threegroups were followed up with visual acuity and posterior capsule opacification for one year. Statistical analysis was used to compare these data.Results: There was no significantly difference between three groups after one week,one month, and three months concerning best-corrected visual acuity groups vision.After12months,24eyes (41.96%) of group A,14eyes (16.88%) of group B,3eye ofgroup C (3.80%) occur posterior capsule opacification. After six months of surgery,5eyes of group C occur posterior capsule opacification. However,2patients werealleviate at one year after surgery. As to PCO grading, there were significant differencesbetween group A and group B (P <0.017), group A and group C, the difference wassignificant ((P <0.001) at six months after surgery. However, B group and C group hadno significant differences at that time (P=0.094). At12months after surgery, thesignificant differences were found in the group A and B group (P <0.017), group A andgroup C (P<0.001), group B and group C (P <0.017).Conclusions: After cataract phacoemulsification, doing posterior capsular polishing andcompletely viscoelastics sucking can effectively reduce the incidence of capsularopacification.
