The Clinical Observation of the Dry Eye Syndrome before and after Cataract Surgery

Objective: To observe the incidence and recovery of the dry eye syndrome before and after cataract surgery.Method: Selected 42 cases of cataract patients(46 eyes)in our hospital from January 2010 to December 2011 as the study object,all patients were treated with a clear corneal incision phacoemulsification and intraocular lens implantation.Observed preoperative,postoperative 1day,1 week,1 month after surgery,postoperative 3 months of dry eye,basal tear secretion test(SIT),tear film breakup time and corneal staining.Result: Compared with before surgery,patients have varying degrees of symptoms of dry eye; compared with preoperative and postoperative first day,1 week and 1 month symptoms of dry eye was significantly higher tear secretion were significantly reduced significantly shorten the tear film breakup time,corneal staining increased significantly,the difference was statistically significant( P 0.05); 3 months after surgery the above indicators returned to normal,with no significant difference compared with preoperative( P 0.05).Conclusion: Phacoemulsification and intraocular lens implantation would be the ocular surface,and in the short term to affect the tear film function in patients,patients there will be varying degrees of symptoms of dry eye,active prevention and treatment.
