This technical glossary includes over 500 terms from optics, geometry, corneal topography, and ophthalmology that are essential in the description of anterior segment topography and its application. Such applications include refractive surgery, cataract surgery, laser ablation profiling, and power calculations for intraocular pseudo-phakic and intraocular corrective lens implantation. This glossary is periodically updated to conform to the emerging ANSI standard on corneal topography. Currently, there is no standard for anterior segment topography. One purpose of this glossary is to develop a useful and consistent set of terms serviceable in anterior segment topography.
