Clinical analysis of the treatment of 202 patients with senile cataract in Linxi Hospital

Objective To observe the efficacy of small incision non-phacoemulsification extraction of cataract for the senile cataract. Methods Two hundred and two eyes of 156 cases with senile cataract in our hospital between January 2011 and December 2011 were randomly divided into two groups. Seventy-eight cases (105 eyes) in group A underwent the small incision manual cataract extraction, and 78 cases (97 eyes) in group B received phacoemulsification surgery. The visual acuity, corneal astigmatism and the complication 1, 7 and 30 days after surgery were compared between two groups. Results The vision of patients in group A 1 day after surgery was better than that of patients in group B (χ2=4.150, P=0.042), and the difference was statistically significant. However, the difference in vision of patients between 7 and 30 days after surgery was not statistically significant. The postoperative corneal astigmatism of patients in group A was significantly higher than that of patients in group B (t=2.345, P=0.02), and between 7 and 30 days after the operation the difference was not statistically significant (t=0.676, 0.214, P=0.510, 0.816). The difference in complications between two groups had no statistical significance. Conclusion Small incision non-phacoemulsification for senile cataract is effective, simple, easy to learn and cheap. It is recommended to perform in primary hospitals.
