What is a conductive keratoplasty?

conductive keratoplasty (CK) is a type of non -invasive refractive surgery that uses heat from radio waves to reduce collagen surrounding the cornea in the eye to improve presbyopia, a condition where the eye is difficult to focus on objects in different mixtures due to aging Hyperopia and hyperopia and hyperopia and hyperopia and hyperopia and hyperopia and hyperopia and hyperopia also known. Keratoplasty refers to transplantation or grafting of the cornea. The cornea is a bright, shiny dome that covers the iris and the pupil in the front of the eye and provides most of the quarry and focusing forces of the eye. The refraction is bending light as it passes through the medium, which shortens the focal length in the eye, making it easier to focus the eye. From the front to the rear are layers of epithelium, Bowman membrane, tree, descenex membrane and endothelium. Guidating keratoplasty concerns the peripheral -cobellast of the tree, the bright, the hard, fibrous layer composed of parallel fibrillas koliawell.

During conductive keratoplasty, the eye surgeon will anesthetize the eye locally and then insert the speculum to open the eye. The surgeon then uses a thin tool similar to Peru to draw small circles around the cornea using radio waves or radiofrequency (RF) energy. This energy generates a slight heat that reduces the collagen of peripheral cornea to a tight zone. This transforms the curvature of the cornea, making it a steeper angle. The new curvature allows the light to bend more drastic when entering the eye so that the patient can concentrate on a shorter distance.

patients with hyperopia, presbyopia or both suffer from negative curvature changes and thus the refractive corneal procedure. In patients with a capital letter, this is usually related to too short an eye lump or a tobjective is not enough round enough, causing the inability to focus on almost objects. In patients with presbyopia, aging causes elasticity lossY and hardening in the lens and degradation of curvature muscles, which in turn causes a reduction in refractive energy. This usually occurs in patients in the 1940s. Conductive keratoplasty is not a good choice for those who have myopia or myopia, but it has been shown to work well for patients with hyperopia and presbyopia.

Food and drug management (FDA) approved conductive keratoplasty for use in 2002; First only in patients over forty with foresights and later in patients with presbyopia. Unlike hyperopic patients, patients with Presbyopia travel agency have only one eye and leave the dominant eye untreated. The untreated eye can then focus on greater distances, while the treated eye can focus on objects within reach. For this reason, conductive keratoplasty is often preferred over glasses or contact lenses because IT is less likely to disrupt the distance. The procedure for presbyopia may not be the best choice for all patients so doctors oftenThe patient examines the individual lenses over the non -dominant eye in advance to test whether the vision remains clear of distances.
