Rose K lenses: Rose K lenses is a family of lenses specially designed to mimic the shape of cornea in Keratoconus . These lenses can help improve vision in keratoconus and provide good comfort and eye health. Rose K lenses also have an application is other conditions with irregular cornea like post graft, post lasik ectasia, pellucid marginal degeneration etc.
Scleral lenses: Scleral contacts are large-diameter rigid gas permeable contact lenses that rest on the white part of the eye called the Sclera. Scleral lenses functionally replace the irregular cornea with a perfectly smooth optical surface to correct vision problems caused by keratoconus and other corneal irregularities. Also, the space between the cornea and the back surface of a scleral lens acts as a fluid reservoir to provide comfort for people with severe dry eyes who otherwise could not tolerate contact lens wear.
Ortho – K lenses : are specially designed rigid gas permeable contact lenses with reverse geometry that are worn overnight. While wrn overnight, the lenses gently reshape the front surface of the eye - cornea so you can see clearly the following day after you remove the lenses when you wake up. These lenses are mainly used to correct eyes spectacle number or to slow down the progression of myopia ( nearsightedness) in young children.
