Types Of Contact Lenses For Keratoconus
Hybrid contact lens options for patients with keratoconus include synergeyes kc clearkone and ultrahealth.
Types of contact lenses for keratoconus. Scleral contact lenses for keratoconus many optometrists and ophthalmologists recommend scleral contact lenses for a variety of hard to fit eyes including eyes with keratoconus. Scleral contact lenses are large diameter lenses that provide clear and comfortable vision for keratoconus patients because the lenses do not actually touch the cornea. Rigid gas permeable rgp or gp contact lenses are primary option for correcting kc vision. Generally scleral contact lenses provide the best fit comfort and visual acuity for someone with keratoconus.
Rgp rigid gas permeable contact lenses these lenses also known as hard contact lenses are not as flexible as soft lenses. While indicated for keratoconus the continuum of care sweetspot is for patients with mild to moderate keratoconus. Keratoconus lenses today include rgp lenses soft lenses piggy back lenses hybrid lenses toric lenses vaulting lenses scleral lenses and custom made soft contact lenses. In cases of early keratoconus a standard gp lens may be used.

There is no one design that is best for every type or stage of keratoconus. They are usually used to correct the greater amounts of astigmatism or corneal irregularities present in keratoconus giving better vision than either glasses or soft contact lenses. Rigid defines the type of lens. Gas permeable contact lenses rgp or gp rgp rigid gas permeable contact lenses are the most widely used method of improving vision in patients.
Depending on the severity of keratoconus shape of your eye and personal details one type of lens may be better suited than another. Ultrahealth lenses are the most advanced hybrid lens. Scleral contacts are larger in diameter than conventional gas permeable gp contact lenses which allows them to vault over even relatively large areas of distorted cornea eliminating much of the irregular astigmatism and other refractive errors caused by keratoconus.
