[Measurement of the anterior chamber depth with the slitlamp and the keratometer].

A simple and accurate formula for the measurement of the anterior chamber depth with keratometer and slitlamp is described. The calculation takes into consideration the curvature of the anterior corneal surface and the refractive index of the aqueous. The method was tested with a model of anterior chamber double-blindly and proved accurate and reliable. The average anterior chamber depth of 50 patients (100 eyes) measured by this method was 2.97 +/- 0.22 mm.
