Anterior Segment Optical Coherence Tomography (Anterior Segment OCT) is an imaging device used to visualize the front structures of the eye, including the cornea, iris, and anterior chamber. It uses light-based scanning technology to produce detailed cross-sectional images without touching the eye. The device helps evaluate corneal thickness, diagnose anterior eye disorders, and assess glaucoma risk by examining the drainage angle of the eye. It is also widely used in planning and monitoring refractive and corneal surgeries in ophthalmology clinics and hospitals.
