CATARACT
Cataract is the presence of opacity in the crystalline lens of the eye. It causes painless, progressive blurring of vision.
It is the leading cause of blindness worldwide and the most prevalent ocular disease.
The initiating events that lead to loss of transparency of both the cortical and nuclear lens tissue is the oxidation of the membrane lipids, structural or enzymatic proteins or DNA by peroxidases or free radicals induced by UV light.

Follow Up

Post-op Follow-up

  • Frequency is based upon on the goal of optimizing the outcome of surgery & immediately recognizing & managing complications
    • First visit w/in 48 hrs post-op is recommended for patients without high risk or signs & symptoms of possible complications after small incision cataract surgery & subsequent visits will be based on the goals mentioned above
    • 24 hrs post-op first visit is recommended for patients w/ functionally monocular, intra-operative complications, high risk of immediate post-op complications & more frequent subsequent visits
  • Patient should be instructed to seek immediate consult to the ophthalmologist if the following symptoms occur:
    • Significant reduction in vision
    • Progressive redness
    • Increasing pain
    • Periocular swelling
  • Optical correction can be prescribed between wk 1-4 post-op in small-incision cataract surgery & between wk 6-12 post-op in sutured large-incision cataract extraction surgery
  • To provide an accurate prescription for eyeglasses for the patient’s optimal visual function, a final refractive visit should be made
  • To reduce astigmatism, sutures if used may be cut or removed by the ophthalmologist
