Abstract

Objective: To describe the clinical characteristics of dry eye in patients after refractive surgery at Saigon - Hanoi Eye Hospital. Subjects and Methods: This study was designed as a prospective descriptive study on 158 eyes of 79 patients who underwent surface laser refractive surgery. The dry eye condition was assessed using the Ocular Surface Disease Index (OSDI) questionnaire and by conducting the Schirmer Test I, Schirmer Test II, Tear Film Breakup Time (FBUT), and Tear Meniscus Height. The criteria for defining dry eye were based on the standards of the Asian Dry Eye Society, with an OSDI score of 13 or higher. Patients were assessed for dry eye before surgery, and at 1 week, 1 month, and 3 months post-surgery. Results: The incidence of dry eye pre-surgery and at 1 week, 1 month, and 3 months post-surgery was 38.3%, 86.1%, 63.0%, and 38.2%, respectively. Schirmer Test I results at pre-surgery, 1 week, 1 month, and 3 months post-surgery were 13.7 ± 4.8 mm, 9.0 ± 5.7 mm, 10.7 ± 5.0 mm, and 14.3 ± 5.1 mm, respectively. Schirmer Test II results at pre-surgery, 1 week, 1 month, and 3 months post-surgery were 4.3 ± 2.5 mm, 5.3 ± 2.5 mm, 8.1 ± 3.8 mm, and 8.1 ± 3.9 mm, respectively. FBUT results at pre-surgery, 1 week, 1 month, and 3 months post-surgery were 5.2 ± 1.5 seconds, 3.8 ± 1.3 seconds, 4.9 ± 1.2 seconds, and 5.5 ± 1.6 seconds, respectively. Conclusion: The condition of dry eye peaked at 1-week post-surgery, then gradually decreased and returned to pre-surgery levels, indicating that dry eye is only transient and does not affect the therapeutic efficacy of refractive surgery.
