LASIK is the most occurring laser eye surgery that performs to treat astigmatism, myopia (nearsightedness), and hyperopia (farsightedness). Just like another sort of refractive surgery, the procedure of Lasik modifies the cornea to allow the light to properly enter the eye focuses on the retina for better and clear vision. The LASIK word refers to “Laser-assisted in situ keratomileusis.” Lasik surgery is elective that is performed by an ophthalmologist (an eye surgeon) of adults, either in an eye surgical center or in the office of a healthcare provider.
Lasik is an eye surgery that is well-known and most occurring laser refractive surgery to resolve all the problems of vision. Laser-assisted in situ keratomileuses (LASIK) can be a substitute to contact lenses or glasses. While LASIK surgery, a unique kind of cutting laser uses to alter the shape precisely of the dome-shape visible tissue at the front side of your eye (cornea) for clearer vision. In eyes having normal vision, the cornea refracts the light accurately on the backside of the eye (retina).
But having astigmatism, farsightedness (hyperopia), or nearsightedness (myopia), the light incorrectly bends that proceeds to blur vision. Contact lenses or glasses can improve vision, but transforming itself the cornea also gives significant refraction. LASIK surgery consists of utilizing a laser that targets to transform the cornea, the front side of an eye. So performing that, refractive faults such as farsightedness and nearsightedness problems through the way light refract in an eye that corrects and vision sometimes enhances permanently.
While normally considered effective and safe, there are sort of risks and some recovery perspectives to consider. Additionally, not everyone who wants to have LASIK is a befitting candidate. LASIK surgery is significantly pain-free and it only takes 15 minutes to perform for both eyes. The results show better and clearer vision without any contact lenses or eyeglasses. The results begin right after the surgery and the vision mostly continues to stabilize and improve over some days. There are three chief parts of the LASIK eye surgery such as corneal repositioning, corneal flap creating, and corneal reshaping. (1)
If you are not a suitable LASIK candidate, several other vision surgeries for correction are also assessable, like phakic IOL surgery, LASEK, and PRK laser eye surgery. If you require a complete eye examination, then visit your doctor or optometrist, who will be able to explain to you if you are a suitable candidate to perform laser surgery before you go out to a LASIK specialist. In a way to perform LASIK surgery, a patient must fulfill the criteria such as have nearsightedness, farsightedness, or astigmatism that is stable and not too critical (it does not alter within the last year). And the patient should be 18 years old at least.
Optical conditions and abnormalities such as dry eye, the cone-shaped cornea (keratoconus), uncontrolled or advanced glaucoma, and a few other health conditions such as uncontrolled diabetes, eliminate you as a member of this process. LASIK reforms the cornea so the light can refract (bend) completely and can properly focus on the retina, where it will convert into the nerve signals sent back into your brain that interpret as visual photos. LASIK surgery aims to improve the vision permanently. In most cases, LASIK removes the requirement to wear any contact lenses or eyeglasses. That means post-surgery vision might not be precise forever. (2)
