    摘要: A hand-held or wearable device for cooling tissue of an eye of a patient is disclosed. In one aspect, the device includes a reservoir having fluid therein and a support connected to the reservoir and configured to be positioned on a face of the patient. The device also includes a nozzle positioned proximate to the support and fluidically connected to the reservoir, the nozzle configured to pass the fluid from the reservoir onto a surface of the eye. The device further includes a cooling element configured to cool the fluid from the reservoir such that it exits the nozzle at a temperature of between −100° C. and 15° C. The device further includes an ultrasonic vibrator positioned near the nozzle and configured to generate mist from at least part of the fluid.
