This review provides an updated overview of the clinical applications of anterior segment optical coherence tomography (AS-OCT) in ophthalmology. AS-OCT has revolutionized the assessment and monitoring of anterior segment structures, including the cornea, conjunctiva, sclera, anterior chamber, and iris. The review highlights the potential of AS-OCT in diagnosing and managing various anterior segment pathologies, such as conjunctival neoplasia, pterygium, keratitis, keratoconus, corneal dystrophies, and infectious/noninfectious keratitis. Additionally, it discusses the use of AS-OCT in preoperative planning and postoperative monitoring for corneal and refractive surgeries. Key features of AS-OCT, such as its technical aspects, corneal anatomy, and clinical applications, are detailed, emphasizing its role in providing high-resolution imaging and quantitative measurements. The review also explores the utility of AS-OCT in detecting and monitoring complications following corneal and refractive surgeries, such as graft rejection, interface fluid syndrome, flap displacement, and epithelial ingrowth. Overall, AS-OCT is recognized as a valuable tool for improving the accuracy and efficiency of anterior segment diagnostics and management.This review provides an updated overview of the clinical applications of anterior segment optical coherence tomography (AS-OCT) in ophthalmology.
