LASIK Surgery - Treatment, Procedure And Side Effects

What is the treatment?

LASIK stands for laser in-situ keratomileusis. This surgery is used to rectify vision problems in people who suffer from farsightedness (hyperopia), nearsightedness (myopia) or astigmatism.

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.

How is the treatment done?

The treatment includes the following steps:

  • The eye surgeon primarily creates a circular, thin ‘flap’ in the outer layer of the cornea.
  • For doing so, the surgeon uses a surgical mechanical tool known as femtosecond laser or microkeratome.
  • The surgeon then lifts the flap in order to access the ‘stroma’, i.e. the underlying layer of the cornea. He/she then removes some corneal tissues with the help of an excimer laser.
  • The excimer laser uses an ultraviolet beam of light to remove a microscopic amount of the corneal tissue. This allows for the reshaping of the cornea thus allowing light to be focused more accurately on the retina. This improves the vision.
  • People who suffer from myopia, the cornea is flattened whereas people who suffer from hyperopia the corner is made comparatively steeper.
  • This treatment is also used to cure astigmatism where the irregularly shaped cornea is smoothened into a more standard shape.
  • After the cornea is reshaped, the flap is put back into its place. This successfully covers the operated area and allows the cornea to heal naturally.
  • Topical anesthetic drops are required during this surgery. Post-surgery, no stitches or bandages are needed.

Who is eligible for the treatment? (When is the treatment done?)

A person is eligible for the treatment when:

  • He/She is suffering from farsightedness, nearsightedness and astigmatism problems.
  • He/She Is aged 18 years or above.
  • He/She does not suffer from any eye conditions that can negatively influence healing like strabismus (muscle imbalance), amblyopia (lazy eye), etc.

Who is not eligible for the treatment?

People who are not eligible for the LASIK surgery are:

  • An individual having eye diseases like keratoconus, cataracts, glaucoma, corneal disease, herpes simplex, herpes zoster along with certain optic nerve and retinal diseases or infections.
  • Individuals with a history of eye injuries or infections.
  • Pregnant or nursing women are not eligible for the surgery.
  • Patients suffering from dry eye conditions should avoid LASIK treatment

Are there any side effects?

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 -

  • Loss of vision – This is a very rare side effect of LASIK. As per research, 1 in 10000 suffers from loss of vision.
  • Seeing halos, starbursts, ghostlings – These visual problems are referred to as higher order aberrations. While some associate them with post-surgery consequences others believe that these problems are present pre-surgery. Aberrations largely depend on the size of the pupil. A person who underwent LASIK surgery may face these aberrations post sunset when the pupil tends to dilate. However, this happens on rare occasions.
  • Dry eyes – Some people may experience dry eyes post LASIK surgery.
  • Several other complications which may arise post-surgery include infection, flap complications, corneal scarring, retinal detachment, slipped flap, Diffuse lamellar keratitis, etc.

What are the post-treatment guidelines?

The post treatment guidelines include the following:

  • Patients should take enough rest and avoid exerting pressure on their eyes.
  • It recommended wearing dark eyeglasses, protective goggles to prevent harsh lights from entering the eye and rubbing the eyes. It also helps to cure dry eyes which are a side effect of LASIK.
  • Patients are recommended to follow the course of anti-inflammatory and antibiotic eye drops as prescribed by the doctor.
  • Patients should also use eyes drops as prescribed by the doctor to keep their eyes moisturized.

How long does it take to recover?

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.

What is the price of the treatment in India?

The price of LASIK treatment falls in the range of Rs.5000/-Rs.100000/-.

Are the results of the treatment permanent?

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.

What are the alternatives to the treatment?

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.

Safety: High Effectiveness: High Timeliness: Very High Relative Risk: Low Side Effects: Medium Recovery Time: Medium Price Range: Rs. 5000 - Rs.1,00,000
