Laser Correction of Myopia

You are visiting the most popular topic of the Day! "Laser your eye and your 'number' disappears!" That is the talk of the town! 

Laser procedure for Myopia correction is mainly of two types.

Photorefractive keratectomy (PRK)

Photorefractive Keratectomy (PRK)

PRK uses Excimer laser.

The outermost layer of the cornea - The epithelium  is scrapped off. Precise excision of layers of cornea underneath is carried out with the laser. The thickness of cornea excised depends on the degree of myopia. That's all! 

This changes the ability of the cornea to bend the light that enters the eye. Thus light can now get focused on the retina, instead of in the front of it. Thus the Myope is able to see without spectacles!

Advantages of PRK:


Less chances of infection.

Less amount of steroid eye drops are required after procedure.

Faster recovery.


LASIK- Laser in situ Keratomileusis

With the Excimer laser, a flap of the top layers of cornea is made, and the inner layers are excised with Laser. The flap is put back. The thickness of the excised cornea depends on the myopia.



Faster recovery.

Very less/no steroid required.

Top layers remain undisturbed so the eye hurts less after surgery.

Useful for Myopia even in the range of -9 to -19 Dsp.

The Excimer laser got FDA approval in 1998.

The laser procedures are costly and are generally not covered by the health insurance.

Besides correction of the 'number' or the refractive error, Lasers have been used very widely in treatment of various eye problems.
