Without appropriate care, keratoconus can progress to a point at which significant visual impairment occurs. The thinning and bulging outward of the cornea, the eye\u2019s main optical structure, leads to astigmatism and myopia, retinal image distortion, and significant visual impairment.<\/p>\n

The implantation of intracorneal ring segments (IRS) – small curved devices made of a biocompatible polymer material – has been applied with great success for years. These implants, which are appropriately selected for size and precise location, normalize the shape of the cornea and improve vision.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>

IRS are best used in the early or moderate stages of keratoconus. Depending on the degree of corneal protrusion, one or two segments may be implanted. IRS diameter and thickness vary according to the desired degree of cornea flattening and refractive change.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>
