Laser (LASIK) Eye Surgery in India

Laser eye surgery is also known as vision correction surgery or refractive surgery. Errors in the field of vision arise, when light passing through the cornea is not properly focused onto retina.

There are numerous techniques available to rectify this disorder. Some of them are explained below:

• PRK: This stands for Photorefractive Keratectomy. It is a corrective measure for all types of eye disorders. It involves the use of laser, that generates cool ultraviolet rays. These UV rays are made to fall directly on the surface of cornea to reshape it. This method is carried out until the cornea is perfectly structured to focus the right amount of light on retina.
• Lasik: This also serves to provide remedial measures for all types of vision disorders. It involves the use of laser, similar to PRK. But, the laser beams create a flap on the outer surface of cornea and not directly on its internal layer. It is through this flap that the internal tissues are reached and modified.

  Finally, cornea is in a position to perform normally; thus resolving all faulty issues. Lasik is preferred over PRK because it has a shorter recovery time and has no initial discomfort in the post operative period.

• LASEK: This is a hybrid of LASIK and PRK. Neither does this method completely remove epithelial cells as in PRK, nor does it create a flap over the cornea. This method rather loosens these cells with alcohol, leaving it attached to the stroma. Laser is then used to reshape the internal layer of cornea and finally the loosened epithelial cells are rolled back to original position.
• PRELEX: These are corrective measure for presbyopia. In this method a multi focal lens replaces natural lens entirely. Thus, there remains no scope of developing cataracts in future.
• Intacs: This method is primarily used to treat Keratoconus – irregularity of cornea that leads to loss of vision. In this method, two plastic rings are placed on the outer edge of cornea that flattens it. Thus cornea can focus the correct amount of light on retina.

Cost of LASER Eye Surgery in India can range around INR 10,000 to INR 1,45,000 approximately; depending on the type of method chosen.

Laser eye surgeries have the lowest risk factors associated, pertaining to infections or inefficient results. A very thin population may experience some post operative discomfort. Surgeons prescribe medicines and night shields for few days after operation. However, it is important to mention that laser eye surgeries are more suitable for eyes that do not have any retinal problems or other eye diseases.
