Treatment for Refractive Errors

Refractive errors can be corrected by using eyeglasses, contact lenses, or surgery.
Eyeglasses are the simplest & safest way to correct the refractive errors. Your doctor will prescribe appropriate lenses to correct the refractive error & give you the optimal vision.
Contact will works as the first refractive surface of the light rays which are entering the eye, giving a more precise refraction or focus. In so many cases, contact lenses will provide a clearer vision, a wider field of vision & greater comfort. These are safe & effective option if fitted & used properly. It is very important to wash the hands & clean your lenses as instructed in order to decrease the risk of infection.
Refractive Surgery main motto is to change the shape of cornea everlastingly. This will change the eye shape that restores the focusing power of eye by allowing the light rays to focus accurately on the retina for an improved vision. There are various types of refractive surgeries. Your eye care doctor will help you to decide if the surgery is an option for you.

Excimer laser correct the refractive error
The effect of excimer laser to correct the refractive error on cornea is very same as grinding of the glass lens to change the refractive power. In person’s eyes who are with the refractive errors, excimer laser can be used due to its high level of precision, it will alter the shape of cornea to change the refractive power to a desired state & thus correcting the refractive error.
In myopia, the central part of cornea is made as flatter, & so decreasing the refractive power of the cornea & the eye, and hence correcting the refractive error.
Likewise in hypermetropia, the laser will removes a ring of the tissue from the peripheral part of cornea & hence make the central part steeper & corrects the refractive error.
In astigmatism, excimer laser will correct by selectively ablating the cornea in specific required direction.
