Treatment of Myopia
The corrective lenses or glasses are prescribed. These are concave and have a negative optical power. However the use of glasses or contact lenses has no effect on the normal progression of the condition.
Orthokeratology is a non surgical procedure in which special rigid contact lenses are temporarily placed in the eyes to slowly reshape the cornea over time and thus improve vision. However it does not have permanent results.
Photorefractive keratectomy (PRK) is a surgical procedure in which laser is used to remove a layer of corneal tissue to flatten the cornea and thereby allowing light rays to focus on the retina.
A LASIK surgery may be performed wherein the corneal flap is cut and the laser removes a layer of corneal tissue and then the flap is placed back. Removing the corneal tissue flattens the cornea and allows the light rays to focus on the retina.
Phakic Intra ocular Lens (IOL) can be surgically implanted in those with high levels of myopia. The natural lens of the eyes is left intact and the implanted lens can be removed if any problem arises or if change in the power of the lens is required. | |
