CORNEA & REFRACTIVE SERVICES

  

Refractive Errors

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. In people with Refractive Error (or poor vision, such as nearsightedness or farsightedness), the light rays do not get focused on to the retina, due to which, blurred images are formed.


Common refractive errors such as myopia, hyperopia and astigmatism can be corrected by spectacles or contact lenses. However, those who want a life free from the limitations of spectacles and the hassles of contact lens handling, Refractive Surgery offers a permanent solution.


At Vishnu Eye Clinic, our doctors have more than 20 years experience in helping patients get rid of their glasses.


We offer a wide range of refractive solutions to cater to every individual’s need:


1. Traditional Microkeratome - Assisted LASIK


2. Custom LASIK or Wave front Guided LASIK - tailor made to correct the individual aberrations of each eye.


3. Surface Ablation or Epi-LASIK - an option for cases with thin corneas. Especially patients who are not suitable for conventional LASIK.


4. Phakic intraocular Lenses - for patients with very high powers, and those for whom Espilasik might be unsuitable.


5. Conductive Keratoplasty - for individuals over 40 years old need glasses for reading, this revolutionary procedure allows permanent freedom from reading glasses.


Pterygium

A pterygium Is a fleshy growth which grows from the white of the eye (conjunctiva) and starts encroaching onto the cornea, These are commonly seen in tropical countries with increased sun exposure , such as India. At Vishnu eye clinic , we perform pterygium removal surgeries and overlay the bare sclera with a graft to prevent  recurrences. These grafts are held in place with a biological glue.Unlike sutures, the glue reduces post operative irritation


Keratoconus

Vishnu Eye Clinic also offers Collagen Cross-linking with Riboflavin (commonly known as C3R). It is a treatment modality which stops progressive weakening of the cornea which occurs in this particular disorder.During the treatment, custom-made Riboflavin eye drops are applied to the cornea, which is then activated by Ultraviolet A Light (370nm). This process has shown to increase the amount of collagen cross-linking in the cornea as well as strengthen the cornea through various laboratory and clinic studies.
