Optical coherence tomography in cornea and refractive surgery

Abstract

Optical coherence tomography (OCT) is the most promising imaging technique used in ophthalmology today. Noninvasive, noncontact and having quick image acquisition makes OCT a requirement in ophthalmology practice. OCT can be used to gain cross-sectional images of the anterior and posterior segment of the eye. In cornea and refractive surgery anterior segment OCT (AS-OCT) is used in presurgical planning and postsurgical evaluation. AS-OCT is especially needed in phakic intraocular lens implantation, laser-assisted in situ keratomileusis enhancement and lamellar keratoplasty. There are also various promising advancements in AS-OCT imaging, such as intraoperative OCT and ultra-high-resolution OCT. These techniques offer new therapeutic and diagnostic options with increased resolution and improved scanning time.
