LASIK, like any other refractive surgeries, works by restructuring the cornea of the patient i.e. the clear front part of the eye. This allows the light entering the eye to be properly focused on the retina for a clearer vision. An ophthalmologist performs this surgery by using a laser or a microkeratome (a surgical instrument).
In the majority of the cases, performing a LASIK surgery on both eyes can take up to 15 minutes. This treatment is painless and provides the patient with improved vision. Also for most patients, this surgery offers a permanent solution to wearing contact lenses or eyeglasses.
LASIK, a short form of Laser-Assisted In Situ Keratomileusis is the safest type of surgery which promises to let you live freely without the help of contact lenses and eyeglasses. It helps in treating myopia, hyperopia, astigmatism and many other eye diseases. The different types of LASIK include:
This type of LASIK is helpful in treating the problems which are based on the prescription of a patient’s eyeglasses with therapeutic parameters. This treatment is 99 times effective but sometimes it can also result in halos, glare and night vision problems.
This treatment is performed on a wavelight laser. Like conventional LASIK, it is also based on the patient’s eyeglasses prescription and accounts corneal curvature and thickness. This type of surgery also helps in curing halos, glare which occurs during conventional LASIK.
Also known as wavefront or custom LASIK, it is helpful in treating refractive error. Undergoing this type of laser, specific alterations (high order aberrations) can also be cured.
It is known as photorefractive keratectomy which is helpful in treating short-sightedness and long-sightedness. An ophthalmologist performs a special laser to reshape the cornea.
LASEK also known as Laser Epithelial Keratomileusis is the latest form of surgery which is a combination of both LASIK and PRK. During this treatment, no cut or scraping will be performed. It helps in curing astigmatism, short and long-sightedness.
The treatment includes the following steps:
During the entire procedure, your doctor will put anesthetic drops into your eyes to make it numb. Now, the entire treatment will be done while keeping your eyes numb. You might feel slight pressure while the laser will be applied, but there will be no pain at all during the surgery.
An ophthalmologist creates a thin corneal flap using microkeratome during the treatment. After doing this, the practitioner will pull the flap back to expose the underlying corneal tissue. The excimer laser will reshape the cornea in a pre-specified pattern. The flap is now re positioned onto the underlying cornea without sutures.
A few advantages of LASIK are listed below:
Disadvantages of LASIK treatment are listed below:
After the surgery, some patients usually experience discomfort. However, it only remains for a day or two. Apart from these, there are several other side effects, but they are very rare. The side effects are -
The post treatment guidelines include the following:
Eyes start to heal immediately after the surgery. One may start having improved vision within 24 hours post surgery. However, the entire recovery process continues for a longer period of time. It usually varies between 3-6 months depending on the condition of the patient. It will thus allow him/her to live a healthy life with better eyesight.
There are many people who think that LASIK treatment lasts for only a few months, but this is not more than a myth. The treatment could last permanently by treating myopia, farsightedness, and astigmatism. Yes, your eyes can show some kind of changes in the course of your lifetime, but it could not become as bad as it was before the LASIK surgery.
The age between 25 to 40 is the best according to the surgeons to perform LASIK surgery. The surgery is generally not performed on the patients who are less than 18 years as the vision tends to change during adulthood.
The price of LASIK treatment falls in the range of Rs.5000/-Rs.100000/-.
LASIK treatment in the majority of the cases provides with permanent improvised vision. A rare percentage of people again face the problems in the long run. However, such consequences may arise due to the change of the lens within the eye. While some people don’t feel bothered by the changes, few may feel the need to wear prescription eyeglasses or opt for a LASIK enhancement surgery sometime in the future.
There could be many risks factors associated with LASIK which will depend on the surgical procedures, health and age. A patient must consider all these before undergoing the treatment. He/she must clear all the doubts before the treatment is performed. The risk factors may include:
LASIK Surgery has both surgical and non-surgical alternatives. The surgical alternatives include Wavefront-Guided LASIK, Photorefractive Keratectomy (PRK), LASEK (Laser-Assisted Sub-Epithelial Keratectomy), Refractive Lens Exchange, EpiLasik, Corrective contact lenses, Laser Thermal Keratoplasty, Radial Keratotomy, Conductive Keratoplasty and many more. Non-Surgical alternative includes Overnight Vision Correction.
1. You must have the information about your refractive error.
2. You must know what type of laser is recommended to you and why this specific was chosen for you.
3. You must know the possible risks associated with the surgery like:
