  • Corneal heat and stretch method and apparatus
    Patent number: 6364875
    Abstract: A method and apparatus to alter the shape of the cornea of an eye provides for heating a portion of the cornea to a temperature not exceeding the collagen shrinkage temperature, and applying a pressure differential to a portion of the cornea. The combined effect of elevated temperature and stretching forces leads to permanent residual strains in preferred directions, and thus to a permanent new shape of the cornea. The method is applicable to the correction or reduction of myopia, hyperopia, and astigmatism.
