AIM: To study the effects of different position of clear corneal incision of cataract surgery on visual function and quality of life.

METHODS: In this study, 126 cases(126 eyes)in our hospital from April 2013 to April 2014 were selected, who were accepted the transparent corneal incision phacoemulsification and intraocular lens implantation in treatment of senile cataract patients. With digital method were divided into observation group and control group with 63 cases in each group, included the observation group selected the maximum refractive power of the cornea radial axial transparent angle incision, and the control group in the temporal clear corneal incision, compared the two groups of patients with postoperative visual function(VF)and quality of life(QOL), and made statistics of uncorrected visual acuity.

RESULTS: In the observation group, postoperative visual function and the scores of quality of life were 80.3±5.63 and 80.9±0.79, was significantly higher than the control group(74.9±5.24)and(76.5±0.76). And the postoperative uncorrected visual acuity of patients in the observation group was less than that of the control group, while ≤1.0 of patients than that in the control group. There was statistically significantdifference(P<0.05).

CONCLUSION: Transparent cornea in cataract surgery to choose the largest cornea diopter longitude as incision can effectively improve the therapeutic effect, especially on the visual function of patients and to improve the quality of life.
