Cataract

What is cataract?

Cataract is a defective eye condition which is quite common worldwide. It is mostly associated with old age but can rarely manifest in adolescents or children, as well. In this anomaly, the natural lens of the eye which resembles a clear and transparent glass becomes cloudy making it difficult for the light rays to penetrate it. Consequently the vision is affected as only dim images are formed at the retina. To be more precise, the term ‘cataract’ denotes this cloudy lens.

The comforting part is that, it is generally possible to restore the vision completely. With the advent of modern technology in cataract surgery, patients can return home within an hour of surgery and get back into their routine work pretty quick.

Treatment

Surgery cannot be skipped in the treatment of cataract. In the microsurgery done for about less than half an hour, the surgeon removes the defective natural eye lens and implants an artificial lens to perform the functions of natural lens.

Surgery techniques can be classified as traditional SICS and modern Phaco emulsification surgery

  • Small incision cataract surgery with IOL (SICS)
  • Phaco Emulsification cataract surgery with foldable IOL

  • You can resume to official work or business in a weeks’ time continuing to instil the drops as advised during post-operative session. You can travel, as well with appropriate safety goggles to prevent eye from infection.

  • Kindly remember reading, though better than pre-operative period, may not be normal until you wear a glass in accordance with a new prescription which would be issued once you complete a cycle of eye drops and come for a review check-up which is usually 4-6 weeks after surgery.
