Centration and coverage of hydrogel contact lenses.
Decentration of the AOsoft lenses and Bausch & Lomb Soflens occurs during wear. The extent of the decentration of 14 lenses on 36 eyes of 18 subjects was studied by means of a biomicroscope with a reticle mounted in the ocular. Unexpectedly, for the AOsoft vault IV lens greater decentration occurred than for flatter lenses. Corneal toricity showed no correlation with lens decentration.
