AIM: To compare the effect of different phacoemulsification incision on postoperative corneal astigmatism for cataract patients.

METHODS: The cataract patients were selected in our hospital. The patients were divided into control group(corneal limbus opposite curved scleral tunnel incision group)and observation group(above the top of cornea or temporal transparent corneal incision group)randomly. At 1wk; 1 and 3mo after surgery, the change of corneal astigmatism and vision of the patients in two groups were compared and analyzed.

RESULTS:Compared with control group, 1wk; 1 and 3mo after surgery, the average corneal astigmatism and surgically induced corneal astigmatism of the patients in observation group were decreased significantly. The visual acuity and corrected visual acuity were increased significantly. There was statistically significant(P<0.05). Compared with control group, the time for the operation of the patients in observation group was shorted significantly, there were statistically significant(P<0.05).

CONCLUSION: Center distance and small incision corneal phacoemulsification can reduce postoperative astigmatism and improve postoperative visual acuity for cataract patients. It provides guarantee for further strengthen the clinical treated effect for cataract patients.
