For clear vision, the eye’s cornea and lens must bend (refract) light rays properly, so that images are focused on the retina. If the light rays aren’t clearly focused on the retina, the images you see are blurry. This blurriness or refractive error is caused by an imperfectly shaped eyeball, cornea, or lens. LASIK is a surgical procedure that can eliminate a person’s dependency on glasses or contact lenses by permanently changing the shape of the cornea of the eye. It uses an ultraviolet laser to precisely remove corneal tissue to correct the shape for better focusing.
LASIK (laser-assisted in-situ keratomileusis) is today’s most popular surgical procedure for correcting vision problems caused by refractive error, the failure of the eye to properly focus light. Laser vision correction can correct myopia (short sight) upto -9.00 D, Hyperopia (long sight) upto +6.00 D, and astigmatism upto 6.00 D.
Indian Hospitals are equipped with the advanced software system for laser vision correction in which the treatment can be personalized for each eye of the patient.
A personalized zyoptix treatment (Customized LASIK) corrects the refractive errors to great accuracy and provides best quality of vision by additionally correcting the optical aberration of the eye. A tissue saving zyoptix, as the name suggests, corrects the required power using lesser amount of corneal tissue, thus can correct more refractive error in thin corneas. An Aspheric Zyoptix has the double advantage of correcting spherical aberration of the eye as well as maintaining natural corneal shape.
Implantable Contact Lens (ICL) – ICL corrects higher degree of refractive error which cannot be done by laser treatments. Implantable contact lenses (ICL Spherical / Toric) is surgically implanted in the eye between the iris and the natural crystalline lens through a small corneal incision.
Refractive lens exchange – In refractive lens exchange surgery the natural crystalline lens of the eye is replaced with an artificial Intra ocular lens (IOL) to achieve sharper focus, rarely it is opted for young people with very high powers. The surgical procedure is almost the same as cataract surgery and is done under local/topical anaesthesia.
