La córnea o la “ventana del ojo” va haciendo mas delgado, dando por resultado miopía y astigmatismo progresivo. La vista de la mayoría de pacientes con keratoconus puede ser corregida visualmente con lentes de contacto especiales. Puede requerir muchos cambios en graduacion de el lente conforme pase el tiempo por lo que la córnea está cambiando constantemente. El adelgacamiento de la córnea progresa a cualquier edad. En menos de 10% de los casos, un trasplante de la córnea puede ser necesario. Los transplantes de la córnea son los más exitosos de todos los transplantes de órganos con un índice del éxito mayor de 96% en pacientes con keratoconus.

    Extractions: Keratoconus A non-inflammatory eye condition in which the normally round dome-shaped cornea progressively thins causing a cone-like bulge to develop. Keratoconus, often abbreviated as “KC”, results in significant visual impairment. The cornea is the clear window of the eye and is responsible for refracting most of the light coming into the eye. Therefore, abnormalities of the cornea severely affect the way we see the world making simple tasks, like driving, watching TV or reading a book difficult. “Keratoconus is a progressive disease of the cornea that is very difficult to treat. Therefore, patients become more frustrated, contact lens related problems arise and patients can lose sight. The care of a keratoconus patient takes one-on-one time with an eye care professional devoted to their craft,” said Dr. Brett Katzen. “ There is no cookie cutter approach to treating patients with keratoconus and only a few persons have the experience to treat these special patients. Tracey is one of those people and we are very fortunate to have her.” Tracey R. Hamburg completed her Bachelor of Science degree and her Master of Science degree at Johns Hopkins University. She is a licensed Certified Ophthalmic Technician. At Wilmer, she specialized in caring for patients with keratoconus, astigmatism and other corneal diseases. She participated in the training of Johns Hopkins medical students, residents, nurses and ophthalmic fellows. While at Johns Hopkins, Tracey co-authored twelve publications in scientific journals and presented her work at over twenty-five ophthalmology conferences.

    Extractions: 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: 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.

    Extractions: Keratoconus "Keratoconus is a progressive eye condition that sometimes is difficult to diagnose," says Michael Ward, FCLSA, director of Emory Eye Center's contact lens service. "Keratoconus usually affects both eyes and requires careful contact lens management." Typically appearing during the teens to early 20s, keratoconus causes the cornea to thin and form scar tissue, until the eye is cone shaped. Since the cornea is responsible for most of the eyes' refraction, any disruption can cause considerable visual distortion that may not be corrected with spectacles. Individuals with keratoconus require specially designed contact lenses to manage vision. Common misconception: That contact lenses halt the progress of keratoconus. In fact, the lenses simply improve vision while the condition is developing. "However, improperly fitted lenses may worsen the condition by increasing the rate of scar tissue formation," says Ward. Research: A gene has now been identified. However, it does not act alone; it may require other genes or environmental influence to manifest itself. Additionally, it does seem to run in some families.

Note: 64.00 Diopter cone peak, with 7.00 Diopter change to periphery in any stage. Comfort Kone is a true aspheric lens and the design is based on radius changes rather than eccentricity values. This design philosophy creates a consistent fitting system and makes kerataconus fitting a straightforward procedure. Examine the corneal topography and fluorescein examples shown. Results of this nature are typical for this lens. Comfort Kone incorporates a small spherical lens optic zone that fits the peak of the cone and provides the patient with good visual acuity. The lens then flattens into an aspheric curve. this is the fitting curve and creates the alignment and comfort of the lens. There are two peripheral curves, which are also aspheric and complete the comfortable alignment. This curvature combination provides a physically compatible fit to the keratoconic slope.

    http://www.vh.org/adult/patient/ophthalmology/keratoconus/
    
    Extractions: Last Revision Date: April 2002 Keratoconus is an irregular protrusion of the cornea, the clear surface over the colored part of the eye. The cornea acts like the windowpane to the eye. If this windowpane is not smooth, the light will not bend evenly and an irregular image will be formed. Like looking through a bumpy piece of glass. During the early stages of this disease, vision may still be correctable to 20/20 with glasses. The only clue to a keratoconus diagnosis may be from corneal measurements or corneal map. A topographical map of the cornea will show the high and low spots on the cornea, much like a topographical map of the earth will show the mountains and oceans. As this disease progresses, vision will no longer be correctable with glasses. Iron will deposit around the base of the protrusion. The tissue will thin and a scar may develop. In severe cases, a temporary painful condition called acute hydrops may occur when water rushes into the thinned area of the cornea. This will lead to severe scarring. About one in 2000 people will develop keratoconus. Most people will have a mild or moderate form of the disease. Only 10% of keratoconics will develop the most severe form. It typically is diagnosed in the late teens or twenties. However, many people have been diagnosed in their mid to late thirties; this is usually a more mild form of the disease. One eye will precede the other and they will progress at uneven rates. The eyes may go for long periods of time without any change and then may change dramatically over a period of months.

    Extractions: CS Home Search for a Study Participate in a Study Refer a Patient to a Study ... NEI Home Purpose Background Description Patient Eligibility ... NEI Representative To describe the clinical course of keratoconus and to describe the relationships among its visual and physiological manifestations, including high- and low-contrast visual acuity, corneal curvature, slit lamp biomicroscopic findings, corneal scarring, and quality of life. To identify risk factors and protective factors that influence the severity and progression of keratoconus. Keratoconus is a bilateral, asymmetric, chronic, progressive ectasia of the cornea characterized by steepening and distortion of the cornea, thinning of the apical cornea, corneal scarring, and treatment-related sequelae, such as abrasions from contact lenses and surgical complications. Patients experience distorted vision that worsens with disease progression. Their vision is typically corrected with spectacles early in the disease and, later, with rigid contact lenses. Some patients eventually undergo corneal transplantation in one or both eyes. Keratoconus affects people in their prime earning years and profoundly affects their lives. Previous large-scale studies of keratoconus have focused on incidence and prevalence, etiologies, or the clinical management of keratoconus. Few have characterized the course of the disease and risk factors for its progression in large samples of keratoconus patients. The incidence of vision-threatening corneal scarring in keratoconus is unknown. Patients’ most frequent questionshow rapidly their keratoconus will progress, how bad their vision will become, whether they will need corneal surgery, how successful their contact lenses will becannot be answered on the basis of the current body of knowledge.

    Extractions: Will Insurance Cover? What Is Keratoconus? Keratoconus is a progressive non-inflammatory disorder that causes a characteristic thinning and cone-like steepening of the cornea. This steepening results in distortion of vision, increased sensitivity to glare and light and an associated reduction in visual acuity. These symptoms usually appear in the late teens and early twenties. Keratoconus may progress for 10-20 years and then can slow or even stabilize. Each eye can be affected differently. This can result in a dramatic decrease in the ability to see clearly even with corrective lenses. Eyeglasses or soft contact lenses may be used to correct the mild nearsightedness and astigmatism in the early stages of keratoconus. As the disorder progresses and the cornea continues to thin and change shape, rigid gas permeable (RGP) contact lenses can be prescribed. The contact lenses must be carefully fitted, and frequent checkups and lens changes may be needed to achieve and maintain adequate vision.

Glaucoma Keratoconus Macular Degeneration Ophthalmic Migraine Overflow Tearing and Chronic Eye Infections in Infants Plaquenil-related Eye Problems ... Contact Us The cornea is the clear window at the front of the eye. Keratoconus is a condition where the cornea develops a distorted shape producing blurred vision. The eye is normally shaped round like a basketball. With nearsightedness, the cornea is too large and with farsightedness, the eye is too short. With astigmatism, the eye is shaped more like a football rather than a basketball. In other words, it is curved more in one direction than in the direction 90 degrees away. This "football shaped" cornea is what produces the distortion with astigmatism. Associated with this change in corneal shape, is a thinning of the central part of the cornea which eventually produces a "bulge" in the center of the cornea (see photo below). Thus, the name "keratoconus". "Kerato" means cornea and "conus" means cone shaped. The conical shape produces distortion of vision. The football shape analogy produces "regular" astigmatism. This is where the "football" or cornea is shaped differently but is a smooth curvature. In keratoconus, the cornea develops "irregular" astigmatism. This is where each direction of the football shaped cornea has a non-smooth surface much like the peaks and valleys of a mountain range. This produces severe distortion of vision.
