    摘要： A method and device is provided for adjusting the white balance of a digital image by adjusting the values assigned to the red, green, and blue subpixels of a pixel in the image. The adjustment to the subpixels is determined by identifying pixels in the image that have an RGB product greater than a threshold value, wherein the threshold value is based at least in part on an average of the RGB products of each pixel in the image and a variance between the RGB products of the pixels and the average of the RGB products.

    摘要： A thermokeratoplasty system and method for locally heating and reshaping a cornea in a manner that produces a minimal regression of the corneal correction. The system includes a probe that is coupled to a power source which can provide a predetermined power, frequency and time duration that creates a thermal profile within the cornea which extends from the epithelium into the corneal stroma. The electrical return of the probe is a lid speculum which maintains the eye lids in an open position. The probe is placed into contact with the cornea and energy is transferred from the power source to the eye, through the lid speculum and back to the power source. The energy from the power supply is focused by a probe tip that locally heats and denatures the cornea, and causes a subsequent shrinkage of corneal tissue. A pattern of denatured areas can be created around the cornea to correct the vision of the eye. It has been found that power no greater than 1.2 watts, for a duration no greater than 1.0 seconds, will sufficiently induce corneal shrinkage without significant regression of the visual acuity correction of the eye. The probe may have an electronic circuit which prevents usage of the probe after a predetermined number of procedures.

    摘要： Glaucoma treatment device for surgical implant for the treatment and management of glaucoma. The glaucoma treatment device includes a single continuous length of cylindrical member having two ends substantially in a first plane and angled slightly inwards toward each other, two smaller loops having the small loops substantially in a like second plane at a slight outward angle to the first plane and each outer end of the small loops connected to the two ends, and an elongated large loop with a large end radius in between the two ends, substantially positioned in the first plane and connected to the inner ends of the smaller loops. The cylindrical member can consist of polymethylmethacrylate or like material. The device is surgically implanted in the eye under a partial thickness scleral flap in the newly formed scleral bed, and secures a channel for aqueous humor to flow away from the eye.
