ABSTRACT
AIM: To observe the tear film changes after phacoemulsification combined with intraocular lens implantation in age - related cataract patients and to compare the therapeutic effect of hydroxyl-glucoside and sodium hyaluronate on the postoperative dry eye. METHODS:A total of 49 patients ( 70 eyes ) with age-related cataract suffering from dry eye after phacoemulsification combined with IOL implantation were divided into treatment group 1 ( group A, 23 eyes with conventional therapy and hydroxyl - glucoside at 7d postoperatively) , treatment group 2 ( group B, 22 eyes with conventional therapy and sodium hyaluronate at 7d postoperatively) and control group ( group C, 25 eyes with conventional therapy only ) . Questionnaire score of dry eye symptoms, SchirmerⅠtest ( SⅠt) , tearfilm break up time ( BUT ) and corneal fluoresce in staining ( CFS ) were measured at 2d preoperatively and 7, 14, 30, 90d postoperatively. RESULTS: No statistical differences existed among the three groups of preoperative 2d ( P > 0. 05 ). At 2d preoperatively and 90d postoperatively, the results of questionnaire score of dry eye symptoms, SⅠt, BUT, and CFS displayed no statistical differences in the patients of three groups (P>0. 05). While there was statistical significance among preoperatively and 7, 14, 30d postoperatively of the three groups (PCONCLUSION: At the early stage after phacoemulsification combined with IOL implantation, the tear film stability is decreased, which may promote eyesymptoms. Management with hydroxyl-glucoside or sodium hyaluronate plays a role in relief of the structure and stability of the tear film and improves dry eye symptoms, while sodium hyaluronate eye drops is more effective.
