1. Introduction

Imaging and measurement of internal corneal anatomy is the next frontier for better understanding the cornea both before and after a refractive procedure. Accurate biometry is also an essential component for optimising intra-ocular lens (IOL) surgery. Inserting a lens into an eye based on external measurements and expecting them to be stable over decades is unrealistic. The safety of IOL surgery can only be improved by imaging the anterior segment and measuring internal dimensions. Trauma to the anterior segment, diseases such as glaucoma, and the complications of corneal and cataract surgery all benefit tremendously from preoperative delineation of the anatomical pathology. This chapter provides an overview of all these applications.
