The LASIK procedure is a surgical procedure performed on a very delicate part of the eye. Millions of people have had eye surgery through the LASIK procedure, many of them with great success. But not all people qualify for this surgery.
The basics about the LASIK procedure
If you wear glasses or contact lenses, you may have thought about having surgery to correct your vision. The LASIK procedure consists in the use of a laser beam to reshape the shape of the cornea of your eyes – the vaulted, transparent and round part that covers the surface of the eye – with the aim of improving the focusing of the light rays in your eyes. retina. The term LASIK is the acronym for “laser assisted in situ keratomileusis”.
Before deciding on this surgery, you have to think about some things:
- The LASIK procedure is a surgery that is performed on a very delicate part of the eye and is irreversible.
- As with any other surgery, there are risks and possible complications.
- Millions of people have undergone LASIK surgery, many of them with great success, but it is not a recommended procedure for all cases.
- The LASIK procedure does not always produce a perfect vision. Although the LASIK procedure corrects your vision from a distance, it is likely that when you reach the middle of the quarantine you will need to wear reading glasses. LASIK Eye Surgery can not correct or prevent presbyopia, which is the loss of visual focus to see up close caused by age.
- If you are short-sighted and do not need glasses or reading glasses and undergo the LASIK procedure, over time, you may have to start using reading glasses before doing this.
- The benefits of the LASIK procedure may decrease over time. More than 10 percent of patients who underwent the LASIK procedure needed a second surgery called “re-treatment” to restore vision correction. This is more likely in people who suffered from a higher degree of myopia, presbyopia, or astigmatism before LASIK.
- Most insurance plans do not cover this surgery.
Understand how your eyes work
- To see clearly, the cornea and the lens of the eye must deflect or refract the light rays to focus on the retina – a layer of photosensitive cells that line the back of the eye. The retina converts light rays into impulses that are sent to the brain and the brain recognizes those impulses in the form of images. If the rays of light do not focus on the retina, you see a blurred image. This is called a refractive error. Eyeglasses, contact lenses and refractive surgery try to reduce these errors so that the rays of light focus on your retina.
- Refractive errors arise from an imperfection of the shape of the eyeball, the cornea or the lens – or in the case of presbyopia, are caused by a lens that cannot be molded enough to focus on nearby objects. Refractive errors are divided into the following basic types:
