To determine the incidence and severity of dry eye in patients undergoing cataract surgery as determined by grade on the International Task Force (ITF) scale.
Prospective, multi-center, observational, pilot study of 200 patients at least 55 years of age that are scheduled to undergo cataract surgery. The primary outcome measure is the incidence of dry eye as evaluated by grade on ITF level and secondary outcome measures include TBUT, OSDI, corneal staining with fluorescein, conjunctival staining with lissamine, and patient questionnaire to evaluate symptoms of dry eye.
In a preliminary analysis of 49 patients, forty-five percent of patients reported dryness and foreign body sensation. The mean OSDI score was 28.2. The average TBUT was 4.94 seconds, with 64.3% of eyes having a TBUT of 5 seconds or less. 50.5% of eyes had central cornea staining with fluorescein dye. 22.8% of eyes had a Schirmer’s score of 5 or less.
The prevalence of dry eye in patients scheduled to undergo cataract surgery is higher than generally reported. Increased awareness of dry eye symptoms may result in greater propensity to treat dry eye disease and reduce the incidence and severity of dry eye symptoms induced or worsened by cataract surgery.
