LASIK, also known as Laser vision correction or Laser eye surgery, is a type of refractive surgery used to correct some vision problems, thereby eliminating or reducing the need to use corrective lenses or eyeglasses. The purpose of laser eye surgery is to produce a clearer and sharper vision, by bending light rays to focus more accurately on the retina as opposed to some point short of or beyond the retina.

LASIK may be a choice in correcting any one of the following sight problems:

· Nearsightedness or myopia

· Farsightedness or hyperopia

· Astigmatism

Before one decides to pick LASIK as the option of vision correction, he or she should consult an eye care practitioner to determine whether he or she is a candidate for the procedure. However, there are general guidelines including:

· One must be an adult, usually aged 21 or older

· One must have healthy eyes

· One’s vision has to be stable for at least one year

· One must not have an autoimmune disease

Preparation before going in for surgery involves stopping wearing of contact a few weeks to surgery, skipping the eye make-up, knowing what the procedure may cost and arranging someone to drive the patient home.

Benefits of LASIK

This procedure offers a number of benefits to the patients. The procedure enhances vision, with studies indicating that 85% of patients attain a 20/20 or better uncorrected visual acuity and 95% get at least 20/40 vision. This means that more than 80% of the patients, who undergo this procedure, will not require contact lenses or eyeglasses. This will allow the patient to wear other glasses and shades without having to buy specialty lenses. Unless one works in a dirty or dusty place, he or she can go back to normal schedule almost immediately after surgery. However, driving is not allowed. Additionally, after a stabilization period of approximately three months, one does not need follow-up procedures unless the procedure under- or over-corrected the vision.


A small percentage of people may have to undergo another surgical procedure if the condition is under- or over-corrected. One may also still have to wear glasses or contact lenses.

Risks include corneal infection, dry eyes, light sensitivity, scratchiness, red or pink scratches in the eye’s white, decline contrast sensitivity, reduced vision, permanent vision loss and glare.


The cost of LASIK surgery varies from one surgery center to another. The cost depends on the technology that the surgeon uses, surgeon skills and one’s vision prescription among other factors.

    I’m surprised to learn that someone must have healthy eyes in order to be able to get laser eye surgery. For some reason, I thought that the purpose of the surgery was to resolve issues. If that is the case, then what makes an eye not healthy enough to be operated on?

    Thanks for sharing some of the benefits of LASIK. I didn’t realize that more than 80 percent of patients who have this procedure will not have to use corrective lenses. Since the risks seem minimal, I would think that LASIK is an option many patients would want to consider. I will have to ask an optometrist more about my options.
