Abstract 【Objective】 To compare the changes of optical quality in patients underwent cataract surgery with different orientations of clear corneal incision by dual channel optical quality analysis system(OQAS).【Methods】Sixty-four patients with age-related cataract in our hospital from January to May 2016 were divided into two groups according to the location of the transparent corneal incision;the Group A was treated with clear corneal incision located at the temporal side of the eyes, while the Group B was treated with a clear corneal incision at the top of the cornea, which was located around 12 clock.The objective scattering index ( OSI) values and OQAS values ( OV100%、OV20% and OV9% ) of the two groups were compared. 【Results】 (1)The uncorrected visual acuity and corrected visual acuity of all patients were increased gradually from 1d to 1 week after operation, and the visual acuity and corrected visual acuity of the Group A were higher than those of the Group B at the same time point after operation , the difference was significant (P<0.05); (2) The OSI values of the two groups of patients were higher than those before operation at 1d and 1 week after operation, and there was statistical significance in each time point(P＜0.05). The OSI value of the Group A was significantly lower than that of the Group B at 1 D and 1 week after operation, with statistical significance (P<0.05);The OV9% values of the two groups of patients at each time point were higher than those before the operation at 1d, 1 week,1 month and 3 months, all of which had statistical significant(P<0.05) .The OV9% values of the Group A at each time point were significantly lower than those in the Group B, the difference was statistically significant (P<0.05). 【Conclusion】 The application of clear corneal incision located at the temporal side of the eye in cataract surgery may acquires less intraocular scattering than that of clear corneal incision at the top of the cornea with a faster vision recovery and better optical quality.Yet,the long-term effect needs to be further studied.
