Is Lasik Eye Surgery Safe?

LASIK eye surgery correction has been in use since the mid-1990s, but a lingering question is : Is LASIK eye surgery Safe ?

Lasik eye surgery is becoming more and more common, but what exactly is this surgery doing to our eyes.

LASIK, laser-assisted in situ keratomileusis, is a surgical procedure that utilizes a laser to permanently change the shape of the cornea to correct vision. Nearsightedness and farsightedness are both caused by distortions in the cornea.

LASIK surgery is relatively simple. A qualified surgeon uses a “microkeratome” or small corneal cutting instrument to cut a thin flap in the cornea. The cornea is

the clear part of our eye that allows light to enter the eye. A doctor may alternatively use a laser to create a cut or flap in the cornea.

Once cut, the surgeon folds this flap back and removes a specified amount of corneal tissue using another laser. This helps reshape the cornea promoting better         vision. During the ablation or removal process a cool, ultraviolet beam of light is passed through the cornea helping reshape it.Once reshaped, your cornea is better able to refract and focus light providing enhanced vision. The surgeon will then replace the flap of skin cut to help protect your eye.

Side effects LASIK surgery

Discomfort during the first few days following LASIK eye surgery correction suchlasik4 as mild irritation and light sensitivity is normal and to be expected. During the first few weeks or months you also may experience: halos; glare and starbursts in low-light environments, especially at night; dry eye symptoms; hazy vision; and reduced sharpness of vision. In the vast majority of cases, these problems are temporary and disappear completely within three to six months.

Complications of LASIK surgery

Irregular astigmatism.  This is caused by an unequally curved corneal surface. Irregular astigmatism also can occur from laser correction that is not centered properly on the eye or from irregular healing. Resulting symptoms may include double vision (diplopia) or “ghost images.” In these cases, the eye may need re-treatment or enhancement surgery.

Dry eyes after LASIK.  Some people who have LASIK surgery experience a decrease in tear production that can cause eye discomfort and blurred vision. Almost half of all LASIK patients experience some degree of temporary dry eye syndrome, according to the April 2006 issue of American Journal of Ophthalmology. Dry eye problems usually disappear when healing of the eye is complete, which can take up to six months.
Eye infection.  While rare, LASIK surgeons report that infections occur more frequently with surface ablations such as PRK. At the 2008 annual meeting of the American Society of Cataract and Refractive Surgery (ASCRS), researchers reported that the LASIK flap, which is lifted during surgery and then replaced to serve as a type of natural “bandage,” seemed to create a more sterile surgical environment than PRK and other surface ablation procedures, thereby reducing the risk of infection.

LASIK eye surgery overcorrection and regression.  Not everyone will achieve 20/20 vision after LASIK eye surgery, and contacts or eyeglasses for some or all lasik3activities may still be required in rare cases. If the laser removes too much  corneal tissue, or your eye’s healing response is not typical, your visual outcome will be less than optimal.  In many cases, the cause of a less-than-perfect outcome is that your eyes did not respond to laser eye surgery in a predictable manner. Another possible cause is that your eyesight may be optimal at first but regress over time due to “over-healing.”

LASIK eye surgery correction has successfully treated millions of patients . However,  LASIK involves potential risk and complications. It is important for you to weigh the benefits and risks before choosing to go ahead with surgery.
