Measurement of the internal diameter and depth of the anterior chamber: IOLMaster versus anterior chamber optical coherence tomographer.

Purpose: To study the internal diameter of the anterior chamber (AC), which remains a relatively subjective procedure dominated by the white-to-white technique, evaluated with a compass or using anterior segment photographs. In vivo dimensions of the AC were studied with an optical coherence tomographer (AC OCT) prototype.

Setting: Clinique Monticelli, Marseilles, France.

Pigment dispersion and Artisan phakic intraocular lenses: crystalline lens rise as a safety criterion.

Purpose: To validate the theory that crystalline lens rise can be used as a safety criterion to prevent pigment dispersion in eyes with an Artisan phakic intraocular lens (IOL) (Ophtec BV).

Setting: Monticelli Clinic, Marseilles, France.

Method: A comparative analysis of crystalline lens rise in 9 eyes with pigment dispersion and 78 eyes without dispersion was performed.
