Changes in ocular surface status and dry eye symptoms following femtosecond laser-assisted cataract surgery
Journal Title: International Journal of Ophthalmology - Year 2019, Vol 12, Issue 7
Abstract
"AIM: To observe the changes in ocular surface and the dry eye symptoms following femtosecond laser-assisted cataract surgery (FLACS). METHODS: Patients with no eye signs or symptoms in Guangzhou Aier Eye Hospital between October 2017 and September 2018, who underwent FLACS and intraocular lens (IOL) implantation for age-related cataract were enrolled. Tear film stability assessed with OCULUS Keratograph 5M, Schirmer’s I test (SIT), and corneal fluorescein staining (CFS) were evaluated before and after surgery at 1d, 1wk, 1, and 3mo in order. Ocular Surface Disease Index scores (OSDI) and Subjective Symptom Questionnaires (SSQs) were recorded at the same time point. RESULTS: Thirty-eight eyes of 38 patients were enrolled. The noninvasive tear film break-up time (first break-up time and average break-up time) decreased in a peak at the 1wk visit, and then increased to basic levels at 1mo. The tear meniscus height (TMH) increased transiently at 1d, and declined in the following 3mo visits. The SIT had a transient increase at 1d (P=0.357) and a decrease at 1wk and 1mo (both P<0.05) but returned to the preoperative levels at 3mo after surgery (P=0.062). CFS scores were significantly improved compared with those before surgery, and had a statistical difference (P<0.05). OSDI scores and SSQs after surgery were obviously higher, and had a statistical difference (P<0.001) but didn’t return to the basic level by 3mo. CONCLUSION: Dry eye signs and symptoms can occur immediately following FLACS and have a peak severity on day 7 postoperatively. Most signs of dry eye can return to preoperative basic levels within 3mo postoperatively. However, all cases can not recover from CFS and dry eye symptoms at 3mo postoperatively."
