Abstract
A variable-applanation patient interface can include a lens support system, attachable to a distal end of an ophthalmic surgical laser system; a contact lens, supported by the lens support system and configured to make contact with an eye-surface; and an adjustable coupler, coupled to at least one of the lens support system and the contact lens, and configured to be coupled to a non-central region of the eye-surface, to accommodate the contact lens to contact a central region of the eye-surface with a central applanation, to enable a change between the central applanation and an extended applanation, and to accommodate the contact lens to contact an extended region of the eye-surface larger than the central region with the extended applanation.
