Panretinal laser fundus contact lens

Abstract

An optical lens system is designed to speed and improve therapeutic laser irradiation of the inner eye. The device is housed in an external casing (10) in conjunction with a specialized fundus contact lens (22). Internally, a disc (12) is mounted with a rotary central mirror driven by a micromotor (14). Toward the periphery of the plate a ring of mirrors is arranged (20). Below the mounted disc lies an additional set of mirrors (24) set at inclinations to divert incident energy to the posterior segment of the eye. As incoming laser energy (28) strikes the central mirror it diverts the beam to a peripheral mirror which again deflects the light to another mirror at the posterior end of the device. A control box (30) facilitates coordinating laser bursts with the circumferential motion of the central mirror. The apparatus results in a ring of laser delivered to the internal eye.
