Imaging the Cornea, Anterior Chamber, and Lens in Corneal and Refractive Surgery

Abstract

Anterior segment OCT (AS-OCT) is an optical and noncontact imaging technology, which has numerous fields of application in the imaging of the cornea, anterior chamber, and the lens. In this chapter, we will present some of the application fields of AS-OCT in corneal, cataract, and refractive surgery. We will emphasize the potential of AS-OCT by several clinical examples including corneal imaging (keratoconus, keratoplasty, and refractive surgery) and intraocular lens imaging after refractive surgery. AS-OCT shows special potential for corneal imaging in case of corneal edema and for postoperative control after Descemet’s membrane endothelial keratoplasty (DMEK). The postoperative follow-up of a posterior chamber Collamer lens’ses vault and measuring the anterior chamber angle could be identified as another promising field of application for AS-OCT.
