Abstract
Methods of treating a refractive error of the eye are disclosed comprising applying a treatment that induces swelling of the corneal tissue and applying an orthokeratology lens configured to correct the refractive error that provides a controlled distribution of the corneal tissue.
Claims20
A method of treating the refractive error of an eye, comprising:
- a first step comprising placing a treatment device on the cornea of the eye, wherein the treatment device is configured to control the area of application of a treatment to corneal tissues of the eye;
- a second step comprising applying to the corneal tissues a treatment that induces swelling of the corneal tissues in the area determined by the treatment device;
- a third step comprising removing the treatment device;
- and
- a fourth step comprising placing an orthokeratology lens that has been configured to correct the refractive error and, optionally, any additional optical errors, of the corneal tissues on the cornea to provide a controlled redistribution of the treated corneal tissues;
- thereby treating the refractive error of the eye.

A method of treating the refractive error of an eye, comprising
- placing on the cornea an orthokeratology lens that has been configured to correct the refractive error and, optionally, any additional optical errors, of the corneal tissues, wherein the orthokeratology lens comprises a septum that permits access to the corneal tissues without removal of the lens;
- applying through the septum of the orthokeratology lens a first treatment to the corneal tissues, wherein the first treatment comprises a buffer solution to adjust the pH of the corneal tissue to between pH 7.5 and 9.5;
- and
- applying through the septum of the orthokeratology lens a second treatment to the corneal tissues, wherein the second treatment comprises an acylation reagent that induces swelling of the corneal tissues;
- thereby treating the refractive error of the eye.
