Corneal heat and stretch method and apparatus |
| abstract |
A method and apparatus to alter the shape of the cornea of an eye provide for heating (44) a portion of the cornea to a temperature not exceeding the collagen shrinkage temperature, applying a pressure differential (40) to a portion of the cornea. The combined effect of elevated temperature, and stretching forces leads to permanent residual strains in preferred directions, thus to a permanent new shape of the cornea. The method is applicable to the correction or reduction of myopia, hyperopia, and astigmatism. |
