Refractive eye surgery is a surgical procedure performed on people suffering from certain eye conditions that require the permanent wearing of glasses or contact lenses. By performing refractory surgery a doctor corrects the refractive state of the eye allowing the patient does to see without the need of glasses. This particulate surgery has been performed for many years and it shows the signs of significant advancements. Surgical techniques have become more refined and have a higher success rate since the introduction of laser vision surgery.
Of the surgical techniques performed to correct refractive errors, laser refractive correction is the most commonly used. The laser allows the doctor to be very precise in manipulating specific tissues in the eye. The surgical correction is painless and improvement in vision is almost instant and the patient may return to everyday activities soon after the surgery.
Who is Suitable Candidate for Refractive Eye Surgery?
People suffering from several refractive errors are candidates for refractive eye surgery. These include patients with, myopia, hyperopia and astigmatism. One more refractive error called presbyopia is not treated with this surgery. Patients suffering from myopia find it difficult to see objects in a distance. In myopia the light rays focus in front of the retina and this occurs as a consequence of increased length of the eye or in case the cornea and lens have too much focusing power. Hyperopia develops due to insufficient length of the eye or in case the cornea and the lens lack focusing power. The light rays in this case focus behind the retina. People suffering from hyperopia generally have problem with close objects (they simply cannot see these objects clearly). In astigmatism the uneven curve of the cornea interferes in proper vision while presbyopia represents a refractive error which affects older people and features with blurriness while looking at close objects.
After the Surgery
It is normal to experience several problems after the surgery such as mild burning sensation and itching. In case of intensive pain patients are prescribed pain relieving medications. The vision is initially blurry but is fully restored within a day. There are potential side effects of refractive eye surgery and they include discomfort/pain, hazy/ blurry vision, scratchiness, dryness, glare, a halo or star-burst around lights, sensitivity towards light and tiny pink/ red patches on the white of the eye. These side effects are temporary and withdraw spontaneously.
