How Does Laser Eye Surgery Improve Vision?


LASIK (laser in situ keratomileusis) or commonly known as laser eye surgery has been recognised as an effective surgical procedure that corrects eye defects like short-sightedness, long-sightedness and astigmatism by reshaping the eye cornea to improve vision. The question on people’s minds is not really how the surgery is carried out, but how it actually improves vision and whether it works or not.

This procedure’s major aim is to improve the vision of people with above-mentioned eye defects, helping them see without the use of glasses or contact lenses. But how does it really do that? This article helps us find out how.

Laser eye surgery. How does it work?

In simple terms, LASIK surgery changes the structure and the relationship of the structures to one another, thereby improving the quality and sharpness of one’s sight without any additional optical appliance like contact lenses or glasses. Note that after the surgery, the eye will still retain some of the manifestations of refractive error such as degeneration associated with high amounts of refractive error and errors like retinal atrophy, however, the eye will be corrected to a level corresponding to the consultation between the patient and the surgeon.

Basically, this means that the eyesight or vision will be sharp, but cannot be returned to its near-perfect state or its state before the procedure.

Most of the time, LASIK surgery improves the spherical and astigmatic component of refractive errors.

Does LASIK surgery really improve eyesight?

Yes, it does. For most people, LASIK is a lifesaver. LASIK surgery helps people achieve 20/20 vision or even better. Success in treatment has been reported in more than 96% of patients who have been through LASIK surgery. There have been lots of patients testifying to the effectiveness of the LASIK surgery. Most patients reported walking into the clinic or surgery centres with bad eyesight and vision and walking out with better eyesight and even better vision after the healing process.

Does LASIK surgery work for everyone?

Besides the fact that certain people are not suitable candidates for LASIK surgery, there are still some patients who run into vision problems after LASIK surgery. Most of the time, LASIK surgery improves vision and corrects refractive errors, but other times, it can also cause other problems like double vision, starbursts, low contrast, and halos by increasing other wavefront errors.

The bad side to LASIK surgery is that the effects are irreversible, and thus any case where there are complications can result in the patient trying endlessly to reverse the changes. In most cases, it can lead to the patient having to use specialised glasses. So no, LASIK surgery does not work for everyone. While it improves vision for more than 90% of its patients, it can end up making matters worse for others.

How can you tell if you will be negatively affected by LASIK surgery?

It can be difficult to tell if you will be negatively affected by LASIK surgery or not; however, during the consultation, your surgeon may be able to find out if you have any medical issues that may present a problem to you. Be sure to pass on any information regarding your medical history to the surgeon during the consultation and ask any questions you may have concerning the LASIK procedure.
