How do keratoplasty lenses work to correct myopia?

  Keratoplasty for myopia is an effective reversible treatment for non-surgical removal of myopic glasses by using specially designed keratoplasty lenses that symmetrically and progressively change the shape of the central surface of the cornea to reduce myopia; similar to laser surgery, but unlike laser surgery, the results produced by keratoplasty are temporary and reversible. While keratoplasty can help most people improve their vision (including patients with astigmatism and moderate to high myopia), it is more effective for a specific range of photometric prescriptions. Other factors include the individual’s corneal hardness, corneal shape, eye pressure level, corneal astigmatism, and suitability for contact lens wear. A complete examination using advanced modern eye examination equipment is required to determine if a wearer is a good candidate for keratoplasty treatment.
