Results
Subjects were 433 eyes of 433 patients undergoing cataract surgery with intraocular lens implantation.  Dry eye examination of tear breakup time (BUT), corneal and conjunctival fluorescein staining scores, total subjective symptom score (12 symptoms), and Schirmer I test were conducted before surgery and 4 weeks after surgery  At 4 weeks after surgery, tear breakup time (BUT) was shortened significantly (P=0.036) than before surgery, corneal and conjunctival fluorescein staining score increased significantly (P=0.012). But total subjective symptom score (12 symptoms) was significantly improved (P < 0.001).  The majority of postoperative dry eye was shortened BUT type (53.1%). The dry eye prevalence after surgery decreased (55.7%) compared with before surgery (69.7%). Females and the patient with dry eye symptoms before surgery had significant risk factors for postoperative dry eye. 
In a randomized study for postoperative dry eye, 154 eyes of 154 patients diagnosed with dry eye postoperatively were applied either 3% Diquafosol Sodium ophthalmic solution (DQS) or artificial tears (AT) six times daily for 4 weeks.  BUT after 4 weeks instillation was significantly prolonged in the DQS group (P=0.015), but not in the AT group. Fluorescein staining score was significantly improved in both groups (P<0.001). Total subjective symptom score was significantly decreased in the AT group (P<0.001), but not in the DQS group.
