How can I choose the best treatment of extreme myopia?
Myopia, also called close, is a condition in which the eye cannot focus on objects that are far distances. There are many degrees of nearsightedness and extreme nearsightedness can lead to glaucoma or blindness in the most serious cases if it is not treated. Myopia can be repaired by contact lenses or glasses or a special type of eye surgery.
Depending on the situation, the patient can choose one of the three options for the treatment of extreme myopia: glasses, contact lenses or surgery. Goggles and contact lenses use a convex lens to focus on the retina images. Surgery was in the form of radial keratotomy, but modern surgery to remedy severe myopia is mostly assisted in situ keratomileusis or lasik. Another form of correction surgery is called photorephractive keratectomy or PK, which is very similar to lasik, but less common.
Goggles and contact lenses can be cumbersome but surgery carries its own set of potentialcomplications. Practically only the risk to the wearer of the glasses is the possibility of loss or breaking and stuck in a situation without proper sight. Contact lens wearers have an added layer of risk in that they are more susceptible to infection. The 2006 analysis said WebMD that those who used contact lenses had a 1% chance of developing serious eye infections over 30 years of use. Lasik surgery complications are very rare, but may worsen reduced eyesight.
myopia can be mild, medium or severe and degree is measured in terms of diopt. Special equipment focuses remote images to the eye and then measure where they land. Slight and medium cases are -6 diopters or less, with extreme nearsightedness is the case of more than -6 diopts.
People with extreme nearsightedness are much more likely to complications from the state. These include the retina department, increased probability of cataract, glaucomaAnd even blindness. Degenerative nearsightedness occurs when the eye continues to extend throughout the life of a person, which worsens and worsens the condition. The most extreme cases of nearsightedness are not degenerative.
Blitova is considered to be a genetic disorder, and the images are aimed in front of the retina in the eye instead of directly on it. As a result, a person is unable to see long distances and will normally squint to concentrate on an object more than a few centimeters away. There was a certain argument that the cause is environmental than genetic and may be the result of excessive use of close supervision.
