Abstract:
A contact lens (318,400,500,600) may include a contact lens body (402), an exterior contact surface (322,404), and an annular bifocal surface (326,408). The contact lens (318,400,500,600) may be configured for use in a contact lens assembly (300) for laser-based ophthalmological surgical treatments. The exterior contact surface (322,404) may be on a first end of the contact lens body (402). The exterior contact surface (322,404) may be configured for direct physical contact with a cornea (102) of an eye (100) of a patient. The annular bifocal surface (326,408) may be on a second end of the contact lens body (402). The second end may be opposite the exterior contact surface (322,404). The annular bifocal surface (326,408) may include a central portion (347,412,502,602). The central portion (347,412,502,602) may include a first focal distance. The annular bifocal surface (326,408) may include an outer portion (349,414,504,604) that surrounds at least a portion of the central portion (347,412,502,602). The annular bifocal surface (326,408) may include a second focal distance.
