Current and Potential Applications of Anterior Segment Optical Coherence Tomography in Contact Lens Fitting

摘要

Optical coherence tomography (OCT) is a non-invasive, high-resolution and high-speed imaging modality that has enjoyed rapid growth in ophthalmology since its development 20 years ago. Contact lens fitting is traditionally based on trial lenses, which is expensive and time-consuming. Modern anterior segment OCT is capable of generating three-dimensional ocular surface maps of the cornea and sclera with potential application in contact lens fitting. This paper reviewed the history, the ophthalmic applications, and the most recent advancement in three-dimensional anterior segment OCT. There is very limited literature of OCT in contact lens fitting to date. This review anticipates an increase in this application in the near future.
