Abstract

To assess preoperative ocular surface findings in consecutive cataract surgery candidates without a prior dry eye diagnosis using a standardized battery of device-based and conventional tests, and to explore associations with age-, sex-, and menopausal status-related factors.
A multicenter prospective clinical study was conducted across 12 centers, enrolling consecutive cataract patients scheduled for phacoemulsification surgery with intraocular lens implantation. Patients were studied preoperatively using a combination of non-invasive tests and traditional diagnostic tools. Test results were classified as physiological or non-physiological based on established cut-off values.
A total of 1,482 patients were enrolled. Despite no preoperative diagnosis of dry eye, 20% of patients exhibited severe ocular surface symptoms via the SANDE questionnaire. Preoperatively, pathological findings were noted in 75.9% for abnormal blinking, 67.6% for reduced TF-BUT, 66.9% for meibomian gland dysfunction, and 43% for eye redness. Older patients and post-menopausal women were found to be at higher risk for ocular surface abnormalities. Logistic regression analysis revealed significant associations between preoperative abnormalities and postoperative risks.
Preoperative evaluation of cataract patients revealed that a substantial proportion exhibited signs of ocular surface disease, despite not reporting ocular discomfort. This highlights the importance of integrating ocular surface evaluation into routine preoperative assessment and considering targeted preoperative optimization, particularly in high-risk populations.
