LASIK Eye Surgery is not Suitable for Everyone


        LASIK Eye Surgery is not Suitable for Everyone


Maybe you are tired of your spectacles or contact lenses. After all, glasses have many problems like they can scratch, break or drift and also feel uncomfortable after many hours of wearing them. Moreover, the common alternative, contact lenses, needs solutions, careful hygiene to prevent infection and, particularly in the case of disposables, is an everlasting monetary commitment.

The idea of living without glasses or contacts is seemingly appealing to around 600,000 individuals a year who get Laser-Assisted in situ Keratomileusis, or LASIK. This refractive eye surgery changes the shape of the cornea and also improves vision. The majority of individuals who get LASIK are happy with the surgery and after surgery, are able to see clearly while not being shackled to prescription glasses or contact lenses.

However, like all surgery, LASIK will have some risks, and a call to electively go through LASIK surgery should be carefully thought out and should be discussed with your eye specialist. In different words, undesirable outcomes can happen after LASIK.

What is LASIK?

You've most probably heard of LASIK; however, you must be unsure how it works.

The surface layer of your eye is termed the cornea. If the cornea’s shape is not normal, light is not properly refracted or focused, and it is harder to see, then with LASIK, an optical laser or blade is used to cut a flap in your cornea. So, an optical laser is used to reshape the cornea before the flap is replaced. Thus, as a result of the change in the shape of the cornea light is better focused on your cornea.

The FDA has approved LASIK for the three conditions:

  • Myopia or near-sightedness
  • Hyperopia or farsightedness
  • Astigmatism (where the curvature of the cornea resembles soccer instead of a basketball)


You should keep in mind that before you undergo LASIK, your specialist is going to perform a comprehensive vision test.

Not every woman is a suitable candidate for LASIK. Subsequent is a list of conditions that discount women as good candidates for this procedure:

  •        If you have a history of diseases, like glaucoma or herpes
  •       History of any eye injury or surgery
  •        Dry eyes (sicca), as happens with Sjogren's syndrome
  •        Thin corneas
  •        Large pupils
  •        Diabetes
  •        Autoimmune diseases
  •        Immune compromise (like HIV/AIDS)
  •        Ectasia, or bulging of the cornea, that happens with astigmatism
  •        Use of corticosteroids, that prevent wound healing
  •        Recent changes in your lens or glasses prescription
  •        Cases of age-related changes to the attention like presbyopia
  •        Very giant refractive errors

Finally, if you have comparatively good vision to start with, you should avoid getting LASIK.

Adverse Effects of LASIK

When LASIK is done properly, the advantages outweigh the risks for many patients. However, negative outcomes can occur even in women that were initially good candidates.

Here are some adverse effects of LASIK that are sometimes gentle and transient:

  •        Dry eyes
  •        Hazy vision
  •        Halos
  •        Sensitivity to light
  •        Starbursts
  •       Double vision
  •        Impaired sight at night

Please note that for a minority of individuals, these symptoms can become permanent and problematic.
Here are some severe adverse effects of LASIK:

  •        Total vision loss
  •        Infection
  •        Corneal Ectasia
  •        Overcorrection
  •        Undercorrection

LASIK does not always have excellent (20/20) vision, and might still have to wear glasses to read. Particularly, if you have got age-related hyperopia or longsightedness that happens in middle or older age that happens due to the decreased elasticity of the lens, so you may still have to wear spectacles. Sometimes, people may need more than one LASIK surgery to correct their vision.

When selecting an eye specialist to perform your LASIK eye surgery, please do thorough research. First, find out the concerning devices used during your surgery and whether or not another refractive surgery, like LASEK, would be better for you. Second, ensure that the specialist whom you have decided on has good expertise. Third, be cautious of discount LASIK procedures or phony promises of guaranteeing you excellent vision.
