摘要
A change in the response of the cornea to ultrasonic energy directed into the cornea is monitored during irradiation of the cornea to bring about corneal crosslinking. Because the change in ultrasonic response is correlated with the degree of crosslinking achieved, a desired degree of crosslinking can be achieved by terminating the irradiation when the change reaches a threshold. The change in ultrasonic response can be determined by taking a baseline measurement before irradiation and additional measurements during irradiation using the same ultrasonic transducer (47). The transducers may be carried on a device (30) resembling a contact lens which overlies the eye and which transmits the light used in the irradiation step to the eye.
