Over 10 million Americans have received LASIK treatment since its Food and Drug Administration approval inand there are aboutadditional surgeries every year. The procedure itself has advanced and refined, sending patient satisfaction rates soaring. While other techniques for refractive vision correction emerge, LASIK — which stands for laser-assisted in situ keratomileusis — remains not only valid, but still the best option for many people seeking freedom from glasses and contact lenses. The doctors at Beverly Hills Institute of Ophthalmology are specialists in this corrective eye surgery.

Since the retina is further back, optometrists prescribe minus lenses that will diverge the light a little further to allow it to land on the retina. The other reason why a person might be myopic is because they might just have too much refractive power in their eyes. To correct this eye doctors will still use minus lenses to cancel out the extra plus power the eye is creating.

Alapvetően, these eyes stopped growing a little too early. When light enters the eye, it will land behind the retina creating that blur at distance and near. To correct this, patients will be prescribed plus lenses to converge the light entering the eye and bring it forward to land on the retina.
