Anterior segment OCT is a non‑contact imaging test that uses light waves to create cross‑sectional pictures of the front of the eye. It visualises structures such as the cornea, anterior chamber, iris, and angle.
What the Scan Shows
The scan provides high‑resolution slices through the cornea and anterior chamber.
- Corneal thickness, wound architecture, and flap or graft interfaces can be assessed.
- Iris configuration and angle width are evaluated for narrow‑angle or angle‑closure risk.
- Implantable lenses and corneal inlays can be imaged in situ.
- Serial scans allow objective monitoring after surgery or cross‑linking.
Clinical Applications
Anterior segment OCT is widely used in refractive, cataract, and glaucoma care.
- It supports planning for LASIK, SMILE, ICL insertion, and keratoplasty.
- Angle imaging aids diagnosis and follow‑up of narrow‑angle and plateau iris syndromes.
- Corneal pathology such as ectasia, scars, and oedema can be quantified.
- The painless, rapid nature of the test makes it suitable for routine clinic use.
