LASIK Eye Surgery and its Advantages

If you wear spectacles, you have probably gotten Lasik surgery as a suggestion by those around you. It is a commonly known procedure that can fix or improve vision. While the idea of eye surgery brings some nervousness, LASIK eye surgery has many advantages. However, only those who fit the requirements can opt for it. 

Let’s see what this surgery is, who it is fit for, and its various advantages below.

What is LASIK eye surgery?

LASIK surgery uses lasers to fix certain types of vision problems. The full form of LASIK is laser-assisted in situ keratomileusis. Here keratomileusis means reshaping the cornea of an eye. “In situ” means “in place.” This surgery is mainly done for 3 problems:

  • Nearsightedness- A person can see nearby objects clearly but not far away objects (Myopia).
  • Farsightedness- A person can see far away objects clearly but not the close ones. (Hyperopia).
  • Astigmatism- A part of the eye has a curve that is irregular, usually the cornea.

LASIK eye surgery aims to correct refraction errors in the affected eye. Refraction means the bending of light. How the light bends when it reaches the eye determines the image formation. The lens and cornea (outermost layer of the eye) bend the light or refract it onto the retina. This information sent to the brain creates the image in front of the eyes. When this light is not refracted on the retina but either behind it or in front of it, the vision formed is blurry. LASIK surgery works on fixing this issue.  

Who can and cannot get LASIK eye surgery?

Conditions other than weak eyesight are important in determining whether a person can get LASIK eye surgery or not. The following factors should be fulfilled to get LASIK surgery:

  • The person should be above 18 years. It is because the cornea should be fully developed before the surgery.
  • There should have been no or minimal eyesight changes in the past 12 months.
  • The person has a refractive error that LASIK eye surgery can correct.
  • The corneas should be healthy and thick.
  • The person should have healthy eyes otherwise.

If a person has any of the below conditions, they cannot get this surgery:

  • Nearsightedness, farsightedness, or astigmatism is extreme.
  • The refractive errors of the eye keep changing.
  • The person has certain eye conditions including dry eyes, thin corneas, glaucoma, cataracts, and eye infection (present or past).
  • Health problems like diabetes that the person may have trouble managing.

Advantages of LASIK eye surgery

Lasik surgery has many advantages that make it a preferable choice for many. 

  • Improvement in vision 

Refractive errors can cause blurred vision, which can be managed using spectacles or contact lenses. With this surgery, a person can achieve an improvement in their vision. Having vision problems can affect a person’s daily life. With this surgery, many things that were challenging because of spectacles or contact lenses don’t become a hindrance. This is because people see a considerable improvement in their vision.

  • Results last for a long time 

The surgery can correct the refraction errors which can last for a long time and can also be permanent in many cases. You don’t have to worry about your vision deteriorating like before. Regular follow-ups with your ophthalmologist (eye specialist) are required to monitor the effects of the surgery. In some cases, people may require another procedure like this after some time. But this depends on the individual’s condition of the eyes and other medical factors.  

  • Minimum or no pain in the surgery

The surgery involves numbing the eyes using eye drops. The person can feel a little pressure when the corneal flap is made, but it is not a painful procedure. No stitches are needed for it. The surgeon uses a laser to fix the refraction error in the eye, during which the patient’s eye has been numbed.

  • Short procedure and quick recovery 

Lasik surgery is of short duration and is usually performed as an outpatient procedure. The recovery is also quick. Vision improvement can be seen right after the surgery, and complete recovery takes a few days. It is recommended to let the eyes heal after the surgery so you should follow the advice of your surgeon for a smooth recovery.

  • Minimal or no requirement for contact lenses or spectacles

With the surgery fixing the vision problem, contact lenses are not needed in most cases. You don’t need to wear lenses and won’t face the risk of eye infections because of them. You need to be careful when using contact lenses. It can be a hassle to always use them cautiously. For those who dislike wearing spectacles, this is a convenient way of getting rid of them. In cases where the fix is not 100%, there may be a need to wear spectacles or lenses, but the requirement is much less than without this surgery.

If you have refraction errors in your vision, Lasik surgery can be helpful. Consult an ophthalmologist to see if it will work for you and any risks it may have.
