[Comparative study of the biometric measurements made by immersion and contact techniques].

Purpose: To compare clinical biometric findings between measurements of immersion technique and contact technique.

Methods: Axial length was measured by A-scan in 120 medical examinations in 60 patients with cataract using a non-contact (immersion) and a contact technique in paired-samples by ultrasound.

Results: The mean axial length was found to be 23.
