The Basics of Lasik
LASIK, or Laser in situ Keratomileusis, often referred to simply as lasik, is a form of refractive keratectomy for the treatment of myopia, hyperopic, and astigmatism. A thin flap is created in the cornea with the use of a laser; this flap is folded back over the cornea so that the normal foveal layer can be placed over it, thereby correcting the vision problem. Lasik surgery is performed on an outpatient basis under local anesthesia. It is a relatively safe procedure, but complications do occur, including dry eye syndrome, formation of scar tissue in the cornea, reaction to anesthesia, irregularities in the patient’s eye, and changes in vision.
The key issue with lasik laser vision correction is that, after the initial procedure, you will have continual contact with the surgeon to ensure that the flap remains in place and that your vision is not diminished. This will require you to wear prescription glasses or contact lenses in order to maintain clear vision. Recovery from lasik is fairly minimal, compared to other forms of vision correction surgeries. In most cases, within eight to ten weeks your vision should be normal. However, it should be noted that lasik procedures should not be entered into until you are in relatively good health and have no prior complaints regarding your eyesight.
As with any medical procedure, there are risks to lasik which you should discuss with your doctor. One common complication is dry eye syndrome, which can develop if you suffer from dry eye syndrome after having your lasik procedure. If you do suffer from dry eye syndrome, your eyes may become irritated and dry. You may also experience itching, tearing, redness, or discomfort near the eye area. Another risk of lasik includes farsightedness or astigmatism, which can be corrected with lasik surgery. If you suffer from either of these conditions your eye doctor will likely give you a list of possible lasik correction options.
