LASIK Eye Surgery



For those suffering from vision problems, the introduction of LASIK Eye Surgery meant new hope for improvement in their quality of life. Conventional LASIK (laser-assisted-in-situ-keratomileusis) is an outpatient procedure that takes only a few minutes on each eye.

Before LASIK, many patients had trouble seeing the alarm clock without glasses. Driving a car, enjoying a sports event or watching a movie without contact lenses would have been unheard of. For decades, many have been dependent on glasses and contacts. LASIK eye surgery has brought freedom to a whole new generation. In a few short minutes, LASIK eye surgery has made an impact on many lives.

Who Is A Candidate?

A comprehensive examination of your eyes and a survey of your lifestyle by a licensed optometrist or ophthalmologist is the best way to determine whether or not you are a candidate for LASIK eye surgery. LASIK can treat a broad range of conditions. These conditions include nearsightedness, farsightedness, and astigmatism. The prime candidate must be healthy and have no eye diseases.

Before having LASIK eye surgery, it is important to have realistic expectations. Most people expect to be completely free of glasses or contact lenses. The reality is that most patients who have this surgery, will significantly reduce their dependence on corrective lenses. However, aging will eventually require corrective lenses in the form of glasses for reading, distance or night driving. Try to think of laser eye surgery as vision correction that reduces the need for contacts or glasses.

Research has provided the following possible results for Custom Lasik. This procedure creates a good chance of having 20/40 vision. LASIK eye surgery can produce a potential for better vision than expected with contacts or glasses. There are also fewer incidences of glare or halos for better overall vision.

Success Rates and Common Results

Success rates for people with common vision problems vary. Before you decide whether to go through with the procedure, you should consider the possible complications. The doctor will explain everything and answer all your questions. All information required for you to make an informed decision will be given to you. It is important for you to understand that even if you are not a candidate for this surgery now, as new technology emerges, you may be one at a later date.

Common Correctable Vision Problems

Myopia is the medical term for nearsightedness. Those with this condition can see objects that are near more clearly than distant objects. For those that wear glasses, the higher the prescription, the thicker the lenses. There are different types of surgery available for those with myopia. These procedures can change the shape of the cornea, which will refocus light directly on the retina.

A realistic expectation for those having corrective surgery with this problem is to have 20/40 vision. This would allow a person to drive a car without glasses or contact lenses.

LASIK surgery is available to correct hyperopia under 6 diopters. There are other procedures available for those with more extensive farsightedness. The success of LASIK eye surgery is dependent on the degree of hyperopia the patient has. Surgical techniques for different degrees of farsightedness are safe. The success rate under these condition is very good, allowing most farsighted patients to perform their everyday activities without eyeglasses or contacts.

Astigmatism is the result of distortion of the lens. Those with this type of vision problem often have blurred vision and cannot make out objects near or far. Correction procedures through LASIK eye surgery vary. As a rule, most eye surgeons consider astigmatism more difficult to correct than nearsighted or farsighted patients. In most cases, if your correction is more than 2.00 diopters, a positive outcome is diminished. As in any surgery, a complete and comprehensive pre surgery examine is crucial.

LASIK eye surgery is available with positive success rates for myopia, hyperopia and astigmatism. All three have positive projected results but depend on individual healing patterns. Conventional LASIK eye surgery is effective for most basic vision errors like those just mentioned and represent one of the most frequently performed operations in North America.
