IMPROVED APPLANATION LENS AND METHOD FOR OPHTHALMIC SURGICAL APPLICATIONS

摘要

The present invention relates to an improved applanation lens (18) for an interface device for ophthalmic laser surgery and, more particularly, an applanation lens (18) formed of a material that is biocompatible with the cornea (34a) and does not discolor and/or have reduced transmittance with respect to its ability to transmit light energy generated by a laser beam during ophthalmic surgery. An applanation lens (18) is a lens with an applanation surface, which is free from aberrations, both spherical aberrations and coma, configured to contact the eye (34) and applanate or flatten the anterior surface of the eye (34) upon application of a pressure.
