Given the popularity of corneal refractive surgery and an aging population of patients who have undergone this procedure, those patients will likely require the diagnosis, follow-up, and management of glaucoma in the future. Since glaucoma examination metrics such as intraocular pressure depend largely on corneal properties, patients who plan to undergo corneal refractive surgery must also undergo a thorough glaucoma examination in order for the ophthalmologist to monitor the development and progress of glaucoma. This article presents an overview of related research on the diagnosis of glaucoma before and after corneal refractive surgery in order to provide reference for clinical work.
