What is Lasik?

Laser assisted in situ keratomileusis (lasik) is a type of refractive surgery used to treat common vision problems such as astigmatism, nearsightedness and foresight. This is also called laser eye surgery, in reference to a device used to perform surgery. The voluntary procedure is usually done from the desire to stop wearing glasses and contacts and the success differs depending on the skill of the surgeon and the patient.

There are several steps to procedure Lasik. First, the patient is evaluated to determine whether he is a good candidate. If the patient is suitable, a number of tests are performed to find out that the eyes are healthy and in good condition. In addition, the surgeon decides how much correction of each eye needs, and the patient is informed of the risks of lasica.Mmation. The patient folds on the table and the surgeon first cuts the flap in the upper layer of the cornea and moves it aside throughout the surgery. Furthermore, the laser is focused on the middle part of the cornea and transforms it with a number of short pulses. This transformedIt is called ablation.

After the ablation is completed, the corneal valve is moved to the eye and the surgeon checks wrinkles and residues. The patient usually notices the immediate difference in vision and the surgeon provides recommendations on subsequent care to support healing. The cornea is one of the fastest healing parts of the body, so the healing process is often short.

In another type of laser surgery, photorefractional keratectomy (PRK), the upper surface of the cornea is actually removed and discarded. This area of ​​the eye regenerates after surgery to form a fresh layer of cells to replace the removed part. The PRK is associated with more postoperative pain, but the patient does not prevail the risk of corneal valve dislocations, which is a well -known lasik problem. This procedure can also be called advanced surface ablation (ASA).

eye surgery is a serious choice and patients should not take it lightly. Finding a good ophthalmologist is essential and patiaNTI should make sure they are informed about the possible risks of the procedure, which may include everything from cracked blood vessels to loss of vision. As with all medical procedures, Lasik is constantly improving, but will never be completely without risk.
