For centuries, people had been wearing eyeglasses to correct refractive vision errors. It was not until the 1950s, when contact lenses were introduced that more people began embracing this corrective procedure. Thanks to the modern technology, you can now get rid of your contacts and glasses.
Laser surgery also referred to as refractive surgery is a surgical procedure used to correct various vision problems. Refractive surgery has become increasingly popular with more people reporting seeing better than they ever had in the past.
The sole purpose of vision correction surgery is to clear the front part of the eye by reshaping the cornea, so that light can travel through it and that the retina is able to focus this light. There are different types of surgery carried out. They include:
This is the most common type of procedure used to correct vision problems such as astigmatism, farsightedness and nearsightedness. During surgery, the corneal tissue is reshaped to ensure that it’s able to focus light into the eye and the retina.
With LASIK, health professional Australian Institute of Eye Surgery says the flap is made in the outer layer of the cornea. LASIK also has other types including custom LASIK, bladeless LASIK and Wavefront Technology. Wavefront LASIK eye surgery uses computer imaging to create a detailed image of your cornea and guides the surgeon throughout the treatment.
With this procedure, the surgeon creates an epithelial flap and then uses alcohol to loosen the epithelial cells. The laser is used to reshape the cornea and the flap is secured with a soft contact lens as it heals.
This laser eye surgery is used to correct mild to moderate farsightedness, astigmatism and nearsightedness. A laser is used to deliver a cool pulsing beam of ultraviolet light onto the surface of the cornea and not under the flap of the cornea like what LASIK eye surgery does. PRK may be done with computer imaging for precision.
These are the common types of laser eye surgery procedures available. They all have their pros and cons. Talk to a laser eye surgeon about your condition and he will be able to recommend the best type of surgery to correct your vision.
