AIM: To investigate therapeutic effect of lateral temporal corneal incision phacoemulsification combined with intraocular lens(IOL)on cataract and its effect on intraocular pressure(IOP)and tear film.

METHODS: The clinical data of patients with cataract who received treatment in our hospital from March 2014 to December 2015 were retrospectively analyzed. According to the location of the incision, they were divided into temporal corneal incision group and upper corneal incision group. We observed the incidence of complications of the two groups, compared the intraocular pressure, visual acuity, refraction and tear film break-up time of the two groups before and after surgery.

RESULTS: The operation time and postoperative pain score of the two groups had no significant difference(P>0.05). The IOP and visual acuity between the two groups before operation had no significant difference(P>0.05). At the intraocular pressure of the two groups was lower than that before operation, and the visual acuity was higher than before operation, and the changes of the anterior lateral incision group were more obvious(P<0.05). The diopter, tear film break-up time of the two groups had no significant difference. At 1mo after operation, the diopter of the two groups all increased, tear film break-up time was lower than before the surgery and temporal corneal incision group changes more obvious(P<0.05). There was no significant difference in the incidence of anterior chamber, corneal edema and anterior chamber exudation in the two groups of patients with corneal incision group.

CONCLUSION: The temporal corneal incision phacoemulsification combined with intraocular lens implantation has a good therapeutic effect on cataract patients, can effectively improve the intraocular pressure and tear film stability, improve eye function, promote the recovery of the body after surgery.
