Outcomes of phacoemulsification in patients with dry eye

Abstract

Purpose: To evaluate the outcomes of phacoemulsification in patients with dry eye.

Setting: Department of Ophthalmology, Post Graduate Institute of Medical Education and Research, Chandigarh, India.

Methods: This study included 25 eyes of 23 patients with dry eye having phacoemulsification. Dry eye was defined as Schirmer I with lidocaine hydrochloride (Xylocaine) score of 5.0 mm after 5 minutes, a tear-film breakup time (TFBUT) of less than 5 seconds, or both. Data were retrospectively analyzed for preoperative and postoperative tear function, postoperative complications, and final visual outcomes.

Results: Of the 23 patients, 18 had age-related dry eye and 5 had secondary Sjögren's syndrome. Twenty-two eyes had predominant aqueous deficiency (Schirmer I with Xylocaine score of 5.0 mm or less), and 3 had a Schirmer score between 6.0 mm and 9.0 mm. The TFBUT was 5 seconds or less in 17 eyes and between 6 seconds and 9 seconds in 8 eyes. The mean preoperative Schirmer score was 4.80 mm +/- 2.01 (SD) (range 2.0 to 9.0 mm) and the mean postoperative score, 3.80 +/- 2.40 mm (range 0 to 7.0 mm). The mean preoperative TFBUT was 4.00 +/- 1.87 seconds (range 0 to 9 seconds) and the mean score at the last follow-up, 3.40 +/- 1.60 seconds (range 0 to 8 seconds). Postoperatively, 8 eyes had superficial punctate keratopathy and 8 had an epithelial defect. The final visual acuity was 6/6 in 13 eyes, 6/9 to 6/12 in 8 eyes, and 6/18 to 6/60 in 4 eyes.

Conclusion: Phacoemulsification was safe and led to minimal complications in patients with age-related dry eye with or without associated systemic disorders.
