Epidemiological insights into complication and outcomes in corneal refractive surgery population: findings from KNHANES 2010–2012

This study provides epidemiological insights into associations between corneal refractive surgery and postoperative outcomes, highlighting dry eye disease and refractive error regression as prevalent findings, while observing that severe complications were rarely reported. Sex and sun exposure were identified as important risk factors for dry eye disease, warranting attention in preoperative counseling and postoperative care. These findings support the need for procedure-specific, longitudinal research to optimize patient outcomes and satisfaction.
