Ortho-K, also known as corneal reshaping therapy, is a specialty contact lens fitting using a rigid gas permeable contact lenses worn overnight to change the corneal curvature, thus modifying the cornea’s refractive power. Combining its unique advantage of providing clear vision without glasses or contact lens during the day, orthokeratology has become one of the most popular and effective choices among children for myopic (nearsightedness) control.
These specialty contact lenses are indicated for keratoconus, pellucid marginal degeneration, post corneal transplant, corneal scarring and ocular surface. Rigid gas permeable lenses rest on the cornea while sclera lenses vault over the cornea and rest on the sclera, the white part of the eye. Although the cost of scleral lenses are higher, it offers patient much better comfort as the contact lens rests on the sclera.
For advance dry eye syndrome, scleral lenses are particularly helpful. The fluid between the back of the scleral lens and your eyes acts like a bandage protecting your dry, irritated cornea. If you have dry eyes and need vision correction, scleral lenses would be a good choice especially when you are not able to tolerate a traditional soft contact lens or rigid gas permeable lens.
For patients with keratoconus or certain corneal diseases and are unable to achieve 20/40 visual acuity with conventional glasses, we can bill MSP directly for the contact lens evaluation. The fee covers RGP lenses fitting fully and scleral lens fitting paritally. It also includes all visits and services necessary for fitting and follow-up for three months.
