Eye glasses Most people can be treated non-surgically with eyeglasses, or contact lenses. Contact lenses The early stages of<unk>  may also be managed with soft contact lenses. Success has been shown with the use of rigid gas permeable contact lenses combined with over-refraction. People wearing contacts don't report increased problems with glare and contrast sensitivity, but it is not clear if this is due to the corneal disease, or the contact lenses themselves. New studies found that the use of Scleral contact lens, a type of rigid gas permeable (RGP) lens, may be a good option for most people with<unk> . Most of these lenses are in the range of 15.5mm to 18.0mm in diameter. Regardless of the lens size, it is thought that the larger the RGP lens will in most cases be more comfortable then standard rigid corneal lenses, and at times more comfortable than soft lenses, regardless of the fact that it is a rigid lens. The highlight to the scleral design and the correction of eye disorders such as<unk>  is that vision with these types of lenses is exceptional when fit correctly. Intacs The use of intacs implants has been tested as a treatment for<unk> , with slight improvement in visual acuity noted after eleven months, and intacs have been used with keratoconus with success. Corneal collagen cross-linking There is evidence suggesting corneal collagen cross-linking may be beneficial for patients with<unk> . Research shows some promising results by combining collagen cross linking with photorefractive keratectomy, or with topography-guided transepithelial surface ablation. Surgery Corneal transplant surgery may be difficult due to the peripheral thinning of the cornea, even with large and off-center grafts. Therefore, surgery is usually reserved for people that do not tolerate contact lenses. Several different surgical approaches may be taken, and no one approach is currently established as the standard. Examples of surgical procedures used for<unk>  include: wedge resection, lamellar crescentic resection, penetrating keratoplasty, lamellar keratoplasty, epikeratoplasty and intracorneal segments. Transplantation of the entire thickness of the cornea (penetrating keratoplasty) may be performed if there is enough normal tissue present. However, if there is not enough normal tissue present, then attaching the graft is difficult. New surgical techniques are in evaluation such as Intrastromal lamellar Keratoplasties and Sclerocorneal Intrastromal Lamellar Keratoplasty (SILK), these techniques allow thickening of the inferior peripheral cornea and steepening of the vertical meridien. Due to the thinning of the cornea, people with<unk>  are poor candidates for procedures such as LASIK and photorefractive keratectomy.
