Laser correction surgery is one of the most popular operations for improving vision. Eye experts, such as Advanced Vision Care, recommend this kind of surgery for an easy, almost risk-free operation to correct eye problems.
One method of laser correction surgery is laser in-situ keratomileusis (LASIK), which corrects near-sightedness, far-sightedness and astigmatism.
Laser correction works by sculpting or burning off small portions of the cornea to reshape it to its ideal shape. The corrected cornea is then capable of properly focusing light to the retina.
Advantages of LASIK
LASIK has been around for more than 25 years and is popular worldwide. Over 96% of patients have the proper vision after the initial treatment. Enhanced treatments increase the proportion of successful operations. It is not painful, and the patient can go home immediately after surgery.
The corrected vision is evident within one day of surgery. Further corrections can be done with succeeding LASIK surgeries even years after the initial operation. The operation’s effectiveness is evident in eliminating the need for eyeglasses and contact lenses.
LASIK uses an ultraviolet laser to remove thin layers of tissue from the cornea. It is an outpatient procedure and takes only 10–15 minutes for each eye. The patient is awake during the operation and the only anaesthesia used is eye drops to numb the surface of the eye.
One or both eyes can undergo the treatment in one session. The procedure cuts a flap of corneal tissue. This serves as the opening to the eye to enable access to the corneal tissue. The flap is a partial sliver of tissue returned after the reshaping of the cornea.
No stitches are required, as the cornea will hold the flap in place. Prior to the operation, calculations are made to determine the amount of burned off the cornea.
