![]() If the keratoconus continues to progress, however, INTACS can only delay the need for a corneal transplant, not prevent it. The implants are removable and exchangeable. INTACS may be needed when the distorted vision from keratoconus can no longer be corrected with contact lenses or eyeglasses. INTACS – INTACS are plastic rings inserted into the mid-layer of the cornea to flatten it, changing the shape and location of the cone.If you are using RGP contact lenses, you will need to visit your doctor frequently to fine-tune the fit and prescription of the lenses, especially if your keratoconus continues to progress. Further, fitting contact lenses on a cornea with keratoconus can be challenging and time-consuming. Rigid keratoconus contact lenses can be less comfortable to wear than soft lenses. The rigid lens covers the cornea, replacing the cornea's irregular shape with a smooth, uniform refracting surface, improving vision. Rigid Gas-Permeable Contact Lenses – If eyeglasses or regular soft contact lenses cannot control keratoconus, rigid gas-permeable (RGP) contact lenses are usually the preferred treatment.As the condition progresses and the cornea becomes increasingly thin, more advanced treatment is required. In the early stages of keratoconus, glasses or soft contact lenses may help to correct the nearsightedness and astigmatism associated with the disease. Your doctor will measure the curvature of your cornea and examine the cornea with a microscope to determine whether these symptoms are a result of keratoconus. Eye rubbing has also been blamed for causing keratoconus or making keratoconus worsen. Genetic abnormalities have been implicated but no definitive proof exists at present. Researchers have determined that there are certain biochemical and cell biology abnormalities that lead to thinning of the cornea. The cause of keratoconus is unclear at present. In patients with keratoconus, the cone-shaped cornea refracts light incorrectly and causes distorted vision. The cornea is the clear, central part of the surface of the eye. ![]() ![]() Keratoconus is a progressive eye disease in which the normally smooth cornea thins and begins to bulge into a cone-like shape.
