Keratoconus is a non-inflammatory thinning and bulging of the cornea. This bulging results in distortion of the cornea, and an associated reduction in visual acuity. Corneal scarring occurs in more advanced cases and further reduces acuity. This page contains facts and explanations about keratoconus, and hopes to answer questions more deeply than other resources the patient may have available.

Conditions Home Macular Degeneration Diabetic Retinopathy Dry Eye Syndrome ... Services Search Selected by the sciLINKS program, a service of National Science Teachers Association. Treatment Keratoconus Overview Keratoconus is a degenerative disease of the cornea that causes it to gradually thin and bulge into a cone-like shape. This shape prevents light from focusing precisely on the macula . As the disease progresses, the cone becomes more pronounced, causing vision to become blurred and distorted. Because of the cornea's irregular shape, patients with keratoconus are usually very nearsighted and have a high degree of astigmatism that is not correctable with glasses. Keratoconus is sometimes an inherited problem that usually occurs in both eyes. Illustration by Mark Erickson Signs and Symptoms Nearsightedness Astigmatism Blurred vision - even when wearing glasses and contact lenses Glare at night Light sensitivity Frequent prescription changes in glasses and contact lenses Eye rubbing Detection and Diagnosis Keratoconus is usually diagnosed when patients reach their 20's. For some, it may advance over several decades, for others, the progression may reach a certain point and stop.

Discovery Fund's Ophthalmic Clinical Trials Center Launched in early 2000, patients in Los Angeles now have an opportunity to be part of cutting-edge clinical research into new devices and drugs to treat eye problems. Helping patients with eye disorders through their participation in quality research studies is the mission of the Ophthalmic Clinical Trials Center. Since its opening, the Clinical Trials Center has contracted with a number of ophthalmic companies to undertake research projects of great importance to the general public. Along with the Ophthalmology Research Laboratories at Cedars-Sinai Medical Center, our team of researchers is paving the way for a unique relationship to unfold - the combination of basic science and clinical research to promote the understanding and management of eye disorders that currently lack effective treatment. Topics for future clinical trials include dry eyes, laser vision correction to prevent "lazy eye" in children, bifocal intraocular lenses, intraocular lenses to correct high myopia and hyperopia, and contact lenses and solutions.

Keratoconus Custom Contact Lenses from ROSE K. The World's Most Prescribed Lens for Keratoconus "The problem with traditional contact lenses is that they do not fit unusual corneal shapes." In simple terms keratoconus causes the bulging of the cornea from its normal round shape to a cone shape. While keratoconus interferes with the clarity of a person's sight it rarely causes blindness. In its early stages, keratoconus causes slight blurring and distortion of vision and increased sensitivity to glare and light. It's complex geometry can be customized to suit each eye and can correct all of the myopia and astigmatism associated with Keratoconus They are easy to insert, remove and clean They provide excellent health to the eye, because they allow the cornea to "breathe" oxygen directly through the lens Find out more about Rose K Keratoconus Contact Lenses

A primary focus of our practice is the care of the keratoconus patient. As evidence of that commitment, Dr. Epstein serves as Vice President for the Center for Keratoconus and on the Medical Advisory Board for the National Keratoconus Foundation . Dr. Epstein also writes Ask the Doctor , a regular column for the NKCF Newsletter. Our strong focus and success in managing keratoconus draws patients from as far away as Europe, Africa, Asia and South America. However the majority our keratoconus patients come from the NY Metropolitan area. We have extensive experience in treating keratoconus and one of the largest keratoconus practices in the United States. Feel free to contact us if you require information beyond what you find here or in the Keratoconus Links offered at the bottom of this page. For detailed information about keratoconus read Dr. Epstein's text in PDF format: What is Keratoconus? Keratoconus is a disorder that causes progressive thinning and distortion of the cornea - the clear dome at the front of the eye. The cornea normally has a rounded shape, but in keratoconus the thinned area bulges forward to produce a cone like protrusion. This results in progressive distortion and reduced vision. Many keratoconus patients experience blurred distance vision, glare, light sensitivity, disturbed night vision, headaches and reading problems, Keratoconus may affect only one eye but more commonly occurs in both eyes. It affects people of all races and both sexes. Most patients develop keratoconus in their late teens to early twenties although it can begin at any age. Pellucid marginal degeneration (PMD) is a corneal thinning disorder related to keratoconus that primarily affects the inferior cornea.

Keratoconus Keratoconus is a condition that affects the shape of the cornea , the clear window surface of the eye . Instead of a spherical-shaped cornea , the cornea has a conical shape .The word ' keratoconus ' literally means cone-shaped cornea . ( To understand the optics of the eye , you may wish to refer to the section on refraction With keratoconus , there is a progressive central or paracentral thinning and bulging of the cornea , leading eventually to the cone shape . An hereditary pattern is neither predictable nor prominent , but positive family histories have been reported ; most cases are sporadic . Keratoconus is generally a bilateral condition , although one eye may be more severely affected than the other eye . Keratoconus develops in the adolescent years and eventually stabilizes over the next 10 to 20 years . As the disease progresses , apical thinning of the central cornea worsens producing extreme degrees of irregular astigmatism . The vision blurs because of optical distortion . In mild cases of keratoconus , at least for a while , vision may be corrected sufficiently with glasses . However

Early cases may require corneal topography, a test that involves making a stereo image that gives a topographic map of the curvature of the cornea. When keratoconus is advanced, the cornea may be thinner in areas. This can be measured with a painless test called pachymetry.

Send Email Keratoconus and Cornea Transplants Introduction I have an eye condition called keratoconus. It's a disease in which the cornea (the outer surface of the eye in front of the pupil) becomes cone-shaped rather than spherical, and this results in extreme astigmatism. Glasses can't correct this vision problem, but hard contact lenses often can. Unfortunately, the distortion of the cornea makes it very difficult to fit contacts comfortably for a keratoconic my eye doctor described it as "trying to balance a saucer on the end of a football." Ultimately, the cornea may suffer scarring which results in vision loss that can't be corrected by contacts. At that point, the next step is to replace the damaged cornea with a new one through cornea transplant surgery. This is only necessary for about 10 percent of keratoconics, but I'm one of them. There's much more about that a bit further down this page... The purpose of this web site is to provide information and resources to those who have keratoconus, and particularly those who have had, or are considering, a cornea transplant.
