Laser Eye Surgery

There are many things you should know about laser eye surgery. Many consider it 100% safe, but it is important to remember that there is always a certain chance of risk, as with any other surgical procedure. Most patients generally get a 20/40 vision, and do not need to wear glasses anymore after surgery, but certain issues should still be taken into account, before one decides on a laser eye surgery. It is definitely a very advanced procedure, and aims to correct the problems of vision. In the procedure, light rays are refracted or bent by the cornea, so as to direct them on the retina. Any person thinking of going in for laser eye surgery should be informed about the procedure, the benefits and risks, and of course – choosing a reliable and suitable eye surgeon is a must. It’s always important to remember that just as with any other surgery, there are certain complications that may occur, so it is always better to be informed and then make a decision. In fact, one possible adverse effect of laser eye surgery is the ability to see distanced objects clearly, but see up-close objects as blurry.

Lasik Eye Surgery

Lasik eye surgery is a kind of laser vision correction that would permanently alter the shape of a person’s cornea – this improves the vision vastly, and brings about a drastic reduction in the need for glasses or contact lenses. Clear vision is defines as the proper refraction of light rays by the cornea and the lens – this makes the images focused on the retina. If there is improper focus and then the images come out blurry – this is called a refractive error, and the cause of it is an imperfectly shaped eyeball, lens or cornea. So what does Lasik eye surgery do, then? It uses an Excimer Laser (a UV laser), which removes the corneal tissue precisely, bringing about a corrected corneal shape which gives better focusing.

Before surgery, the eyes are completely examined to make sure of proper health, and tests are carried out to determine the cornea’s curve, the position and size of the pupils, the eyes’ shape, and the cornea’s thickness. In fact, the last issue is taken into account to make sure that enough cornea tissue is left after surgery.
