You've probably heard of surgery to improve vision if you wear glasses. LASIK and PRK laser surgeries are the most popular types. A lens implant is an additional choice that might be more effective if you have very nearsightedness. These procedures can restore 20/20 vision and lessen or eliminate the need for contacts or glasses. But there may be undesirable side effects from vision surgery. If it can help you depends on your health and eye health.
Suitable Patients for Vision Surgery: People who are astigmatic, nearsighted, farsighted, or both can benefit from laser surgery. But not everyone will enjoy it. You might find success if - from age 21 to 60, there hasn't been a change to your prescription in at least a year, uour overall health and eyesight are fine.
Laser eye surgery comes in a variety of forms. The most well-known and popular procedure is LASIK. The term "LASIK" will be used frequently in articles, including this one, to describe all varieties of laser eye surgery.
Images are frequently concentrated on the retina at the back of the eye. They become focused in front of or behind the retina with nearsightedness, farsightedness, or astigmatism, impairing vision.
When you have nearsightedness, also known as myopia, you can clearly see close-up objects, but distant objects appear blurry. Light rays focus in front of the retina and distort distant vision when the cornea curves too sharply or when your eyeball is a tiny bit longer than average.
Close-up objects are easier to see, but distant objects are not as clear. When you have farsightedness (hyperopia), you are able to see distant objects clearly, but close-up objects appear blurry. Light focuses behind the retina rather than on it when the cornea is too flat or the eyeball is shorter than average.
Both near and occasionally far vision become hazy as a result. A general vision blur is a result of astigmatism. Astigmatism occurs when the cornea flattens or curves unevenly, disrupting the focus of both near and far vision. Traditionally, a person with blurry vision would wear glasses or contact lenses to bend (refract) light rays. The cornea (the transparent dome-shaped tissue at the front of your eye) can be reshaped in order to achieve the required refraction and vision correction. People are eligible for surgery are:
