摘要:
A single-piece patient interface device (PI) for coupling an patient's eye toan ophthalmic surgical laser system, whichincludes a rigid shell, a flexible suction ring joined to a lower edge of theshell, an applanation lens, and a flexible annular diaphragmwhich joins the applanation lens to the shell near the lower edge of theshell. The flexible diaphragm allows the applanation lens to moverelative to the shell, including to shift in longitudinal and lateraldirections of the shell and to tilt. In operation, the surgeon first securesthe PI to the patient's eye by hand, and then couples the laser system to thePI by lowering the laser delivery head into the PI shell. Duringthe lowering process, the laser delivery head presses the applanation lensdown relative to the PI to applanate the cornea of the eye.
