A normal person or an Emmetrope sees well because rays from the outside world fall exactly on the light sensitive retina allowing them to see sharp and clear images of the world. In people with refractive error (or poor vision, such as nearsightedness or farsightedness), the light rays do not get focused on to the retina and blurred images are formed.
Hyperopia refers to the condition known commonly as long-sightedness, wherein the patient has difficulty seeing objects or reading at close distances without the aid of glasses.
Myopia, commonly known as near-sightedness or short-sightedness, refers to a condition where the patient is unable to see distant objects. Myopia is rare before the school-going age, gradually increasing during school life. Myopia maybe low (-5 diopters), moderate (-5 to -10 diopters), or high (more than -10 diopters). Persons with moderate to high myopia are liable to have retinal complications and should have a dilated eye examination at least once a year.
Astigmatism is an optical defect, whereby vision is blurred due to the inability of the optics of the eye to focus a point object into a sharp focused image on the retina.The treatment options for all these refractive errors are:
Spectacles are inexpensive and safe and offer clear vision and are low maintenance.
A scientific optical dispensing unit with an entire array of the latest in lenses and frames laid out in a pleasant and attractive display is also available in-house.
Those who do not want to wear spectacles can opt for contact lenses, which maybe soft and semi-soft or rigid gas permeable. Soft contact lenses may be extended wear or disposable. For high errors of astigmatism, toric contact lenses are available.
Disposable lenses (daily or weekly) are discarded as indicated. All types of lenses should be removed at the end of the day, cleaned and soaked in the specified solution as instructed during their purchase.
Contact Lens Clinic: A state of the art Contact Lens Clinic is functional in the premises with a wide array of soft, semi soft, toric, cosmetic and customized lenses. Most lenses are readily available to suit the individual needs of the patients from the well stocked library.
LASIK (Laser-Assisted In-Situ Keratomileusis) is a very simple procedure of correcting refractive errors by reshaping the cornea with the help of a cold (Excimer) laser, with submicron accuracy. The safety and accuracy of the LASIK surgery or treatment depends largely on the machine used.
