Laser refractive surgery is becoming increasingly popular as people are turning to alternatives to the traditional spectacles and contact lenses for vision correction. This article covers an overview regarding the various techniques involved in refractive surgery. What is the refractive error? Refraction is the bending of light rays as they pass from one transparent medium to another medium of different density.
Myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (different refractive power in different meridians) are different refractive errors along with presbyopia (age related hardening of the lens). Surgical techniques to correct refractive errors: Along with the conventional corrective lenses, spectacles, and the excimer laser, there are various other newer techniques that are used for refractive surgery. In this article, we will see laser-assisted in situ…
