Abstract: Objective To investigate the impact of scleral tunnel incision and clear corneal incision phacoemulsification on tear film of patients with cataract. Methods Totally 86 patients with cataract who received phacoemulsification during February 2014-October 2015 were set enrolled and were divided into two groups according to the different operative insicion, 43 cases in each group. For experimental group, clear corneal incision was used. For control group, scleral tunnel incision was used., The effects of two kinds of phacoemulsification incision on the functions of tear film in each patient were observed 1, 7, 15 and 30 days after operation. Results The break-up time(BUT)in experimental group were obviously shortened compared with operation before, and experimental group were obviously shorter than those in the control group 1, 7 and 15 days after operation, 30 days after the operation, BUT of both groups were obviously longer compared with operation before, the differences were statistically significant(all P<0.05). The secretion levels in both groups were significantly improved compared with operation before, and the secretion level in experimental group were obviously higher than those of control group 1, 7, 15 and 30 days after operation, the differences were statistically significant(all P<0.05). Conclusion Impact on tear film after clear corneal incision phacoemulsification is significantly lower compared with scleral tunnel incision phacoemulsification. Therefore, clear corneal incision is more worthy of clinical pervasive application.
