What Is Lasik Laser Eye Surgery?

The type of refractive surgical procedure used for the correction of myopia, hyperopia and astigmatism is known as laser eye surgery or lasik eye surgery. Myopia is short/near sightedness in which light falls in front of retina instead of falling on it. As a result of this, objects close to the eye appear normal whereas those away look blurred. Contrary to this condition, hyperopia is a condition in which the light tends to fall behind the retina as a result of which objects in closer proximity appear blurred while those far away appear normal. Astigmatism is a combination of both the far and near sightedness. These are refractive disorders of the retina and the lasik surgery aims at the correction of vision problems associated with retina. This surgery is a long lasting alternative to contact lens, spectacles and sunglasses which people tend to use on a chronic basis.

Signs and Symptoms of Refractive Disorders Of Eye:

  • Constant headache in the eyebrow region, temples and near the ears
  • Watery eyes
  • Objects appear blurred
  • Difficulty in reading

Diagnosis of Refractive Disorders of Eye:

  • Dry eye testing: If eyes are dry prior to the onset of lasik surgery, it becomes essential to treat the eyes because the chances of eyes becoming dry will in any case increase after the treatment has been done. Eye drops are advised to be instilled every four hours to correct the dryness of the eyes. If the eyes moisture normally, then it is a heads up for the lasik procedure.
  • Pupil testing: Evaluating the pupil size, especially in the dark, will allow better informed consent. Pupil size can be measured accurately with special devices such as an infrared pupillometer. Patients with larger pupil sizes may be at risk for glare and halos after LASIK surgery.
  • Pachymetry: Accurate corneal thickness measurements are essential to evaluate that proper corneal thickness is present for the treatment needed. Patients with abnormally thin corneas are advised that they may be at higher risk of developing ectasia following LASIK surgery. 
  • Keratometry: Manual keratometry is important to evaluate the corneal shape pre-operatively.
  • Corneal topography: Corneal topography is a valuable three dimensional imaging tool to map the surface of the cornea. Corneal topography is critical in detecting a variety of corneal abnormalities. If certain abnormalities are found, than LASIK may be an unsafe procedure, leading to vision loss in the future for the patient.
  • Wave front analysis: Wavefront testing is used to detect higher order aberrations that may degrade vision. Standard LASIK procedures cannot treat patients with significant amounts of wavefront abnormalities, which may leave them with unwanted visual symptoms after surgery.

Types of Refractive Disorders Of eye:

These occur due to various combinations where light tends to fall anywhere along the path of the retina.

  • Myopia occurs when light falls in front of the retina. As a result of this, the nearby objects appear clear and the ones at distance look blurred. Hence it is also known as near sightedness or short sightedness.
  • Hyperopia is due to light falling behind the retina because of which objects at a distance appear normal and the ones closer by look blurred. This is also called as far sightedness.
  • Astigmatism is a combination of both near and far sightedness and can have variable degrees of vision errors both during day as well as night.

Treatment Procedures for Lasik Laser Eye Surgery:

  • Pre-operative procedure: The patient in concern is advised to stop wearing contact lens for a period of eight to ten weeks prior to the scheduled date of the lasik surgery. Contact lens act as a semi permeable membrane over the retina and tend to reduce the oxygen intake by the retinal cells further adding to the degree of keratinization of the retinal cells. The eyes are checked on a routine basis to rule out any infections or involvement in any syndromes.

It also is imperative to get checked for the vision and any changes in it once every three months for a period of one full year if the patient wishes to opt for the lasik eye surgery. This will help to know about any fluctuations in the vision and the ophthalmologist can give measures to stabilize it and then proceed with the lasik accordingly.

  • Operative procedure: The procedure is always done in local anesthesia. This is done with the use of anesthetic drops. The procedure is never done in general anesthesia, it does more harm than when the patient would have kept his or her eyes open. The patient is asked to keep his or her eyes open without blinking for a period of just 5 to 6 minutes during which the entire procedure is completed. For this purpose, clips may also be used to keep the eyes wide open. Laser beam is projected onto each eye, for 5 minutes where the beam brings about correction of the retinal and the corneal layers.
  • Post operative care: The patient can be discharged from the clinical setup on the same day. A few instructions need to be followed by the patient and visit the ophthalmologist regularly.

Complications And Risk Factors Associated With Lasik Laser Eye Surgery:

  • Aberrations may occur in the retinal layer which may cause the retinal layer to rupture; vision becomes even worse if the technique is not followed in a proper manner.
  • Infections in the sclera and conjunctiva can occur as a result of post operative poor hygiene maintenance.
  • Almost all the cases treated with this procedure complain of dry eyes. However this may not last for more than 15 days; if eyes remain dry for more than this period one should visit the doctor concerned.
  • Conditions like sjogren’s syndrome where eyes and mouth consistently dry are an absolute contraindication for the lasik eye surgery.
  • Flap complications, slipped flap, traumatic flap dislocations, flap interface particles, diffuse lamellar keratitis are the complications that can occur with flap.
  • Sub conjuctival hemorrhage, corneal scarring may occur in a few cases.

Am I Good Candidate For Lasik Laser Eye Surgery?

You are an ideal candidate for a laser lasik eye surgery if you already are following any of the following points:

  • Your number is stable since the last time you got your eye check up done
  • You do not wish to wear spectacles and contact lens all the time; you want to get rid of them
  • You also have not been wearing your contact lens since almost 3 months
  • You are above 20 years of age; surgical corrections are avoided during the period of growth since the condition tends to relapse.
  • The cornea has sufficient thickness, pupils are not wide. This is a finding which the ophthalmologist does.

Recovery Time:

  • The patient gets discharged on the same day as that of the surgery.
  • The patient is advised to not cook, keep out in the sun for a period of two days
  • After that, the patient can follow his or her normal routine that used to be followed earlier
  • Also the patient can bathe normally, watering the eyes after two days

Success Rate:

Lasik laser eye surgery is successful in almost 97 percent of cases. A minimum of 2 to 3 percent cases require glasses while reading; this too occurs after 5 to 7 years of lasik laser eye surgery.

Benefits of Lasik Laser Eye Surgery:

A lasik laser eye surgery will benefit you in the following manner:

  • No need for wearing spectacles or contact lens
  • Avoid any scarring or wound infections since no traditional procedure is being done on your eye
  • Since it is a laser method, no extensive hospital stay is needed and you can get discharged on the same day
  • No elaborate rules need to be followed after the surgery
  • You can resume your daily work soon after the procedure has been done; you can drive yourself home from the hospital too.

Cost comparisons:

If you choose to go for a lasik eye laser surgery in India, you will be required to pay a fee of 25,000 to 35,000 INR. This is roughly around 60 percent less as compared to the cost you will required to pay in US/UK/Australia.
