What is LASIK Eye Surgery?

An Excellent and Effective Alternative for Vision Corrective Eyewear

Many people who have impaired eye vision are often seen asking questions such as ‘what is LASIK eye surgery?’ ‘What does LASIK treat?’ and ‘Do I qualify for this surgery to correct my vision?’

So, here is a complete guide for the people who are seeking answers to these questions. Read on to know ‘what is Lasik eye surgery?’ ‘What refractive defects it treats?’ and ‘who can qualify for this surgery?’

What is LASIK Eye Surgery?

Laser assisted in Situ Keratomileusis (LASIK), is a revolutionary ophthalmologic surgery that many surgeons use to correct imperfect vision. It is a highly specialized vision-corrective treatment in which advanced equipment is used to eliminate minor imperfections in the eye. These visionary flaws are treated with blades or a laser light, to correct the defected corneal tissues

What is the LASIK Eye Surgery’s Success Ratio?

Another widely asked question by many patients who ask ‘what is LASIK eye surgery?’ is ‘how effective the procedure is in correcting vision?’

The good thing with the LASIK eye surgery is that its success ratio is remarkably high which attracts many patients, who are willing to have 20/20 vision. Its tremendous track record attracts millions of people including athletes, actors, politicians and others who want aesthetic beauty by removing their heavy glasses (yes, sometimes they are heavy with thick eye glasses) and irritating eye lenses.

With less than 1% LASIK complications, more than 92-98% of LASIK patients are satisfied with the results. Therefore, it proves that the treatment is effective and result-oriented.

What Kind of Refractive Errors Are Treated with LASIK Eye Surgery?

There are three major kinds of visual impairments that are treated with the LASIK eye surgery and they are: 

Myopia or Shortsightedness:

Myopia is a visual impairment in which a mismatch in the focal length of the eye occurs. This causes distant objects to be unclear and blurry to the patients, however, they can clearly see nearby objects.

Hyperopia or Long sightedness

Hyperopia is the opposite of the myopia. In this eye defect the mismatched focal length of the eye allows a patient to see nearby objects a bit blurry and hazy. However, the patient can clearly see distant objects.

Astigmatism

In astigmatism, either the cornea or the lens of the eye gets out of shape which causes multiple images on the retina. A patient with this impaired vision faces a lot of difficulty in seeing both near and the distant objects.

Furthermore, it is also seen that many patients develop astigmatism in which the symptoms of the impairment are either combined with myopia or hyperopia.  

Who Can Qualify for the LASIK Eye Surgery?

Only the following patients can qualify for the LASIK eye surgery:

Healthy Patients-

Patients with chronic diseases such as diabetes and other complicated conditions such as cataracts, keratoconus and glaucoma are not qualified for LASIK. One should be healthy in order to have LASIK surgery. 

Adults

Patients that are 18 or above are potential candidates for LASIK surgery. There are exceptions in which a minor can be treated with LASIK, but it is quite rare.

Stable Eye Vision

Many people face frequent changes in the focal length of their vision. A potential LASIK candidate should have consistent vision for at least a year, before having the surgery.

Pregnant women

The changed hormonal levels in pregnant women can increase the fluid levels in the body, which can eventually change the shape of your cornea. So, an expecting mother cannot have LASIK.

Autoimmune Diseases

Patients with autoimmune diseases such as AIDS, Sjogren’s syndrome and rheumatoid arthritis are also not eligible for LASIK.

What is the LASIK Eye Surgery’s Procedure?

Several Steps Involved in LASIK Eye Surgery
 

Once a potential candidate qualifies for LASIK eye surgery, the treatment can be swiftly carried out with certain precautions, so as to avoid any complications. However, follow-up treatments and safety measures should be followed.

The LASIK Eye Surgery Procedure

The traditional LASIK eye surgery process is swift and effective. For the patient’s comfort, the eye is first anesthetized with tropical eye drops and then the corneal flap is hinged. This flap can be created by using a surgical blade (microkeratome) or a laser (IntraLase).

After the cornea is reshaped, the corneal flap is closed and is left to heal naturally.

Effectiveness of the Surgery

Many patients demonstrate immediate vision recovery right after the surgery. However, there is no harm in carrying out follow-up treatments.
In short, the cost of LASIK eye surgery is worth the numerous benefits of the surgery, therefore, making LASIK the best and most effective alternative to vision-corrective eyewear.
