CorneaBefore we will discuss the general causes of cataracts, let us first cover the various types leading to the formation of cataracts. Take time reading them and eventually discover which category your cataract development falls into.

Cataracts are categorized through their anatomical location:

  • Within the lens
  • The degree of the clouded lens
  • The general cause of the cataract

If the overall clouding of the patient’s lens happened in the central part of the lens, then it is commonly referred as the nuclear cataract or nuclear sclerosis. In the event, the clouding occurs only in the lens cortex (outer capsule of the lens), it is called the a cortical cataract, while if the loss of lens clarity is in the posterior capsule, it is termed as posterior subcapsular cataract.

The most common kind of cataract growth reported happens as part of the aging process and is usually referred as the “senile cataract”.

Common causes of cataracts

  • As the person ages, the protein components of the lens start to clump and tend to form a clouded part of the lens or cataracts.
  • Some individuals who had blunt or penetrating injury may probably develop secondary traumatic cataracts.
  • Cataract formation can occur after undergoing a previous eye surgery procedure, most commonly after prior retinal surgical procedures.
  • Extreme exposure to different radiations such as ionizing radiation (x-ray), infrared radiation (glass blowers) or ultraviolet radiation.
  • Diabetes is the leading systemic disease to cause cataracts.
  • Inflammatory eye diseases (iritis or uveitis).
  • Genetic illnesses can also lead to secondary cataracts (myotonic dystrophy, galactosemia, homocystinuria, Wilson’s disease and Down syndrome).
  • Congenital infections (herpes simplex, rubella, toxoplasmosis, syphilis and cytomegalic inclusion disease.
  • Certain medications taken over a long period of time may also cause secondary cataracts like the intake of corticosteroids in any form, topical/inhaled/nasal/oral/intravenous/injected.
  • Genetic disorders (intrauterine developmental disorders) resulting to the baby’s physical deformities such as early development of the clouded lens or cataracts.
  • Atopic dermatitis (skin diseases and mucous membranes) could also lead to the early stage of cataract formation.

Patient tips and additional warnings

If you have developed an advanced stage of cataracts, seek immediate medical help from a specialized eye doctor like a cataract doctor. Don’t delay the eye surgery procedure if this is the only resort to gaining a better visual clarity or a way to prevent further damage to the affected eye(s) like permanent loss of one’s vision.

There is always an effective solution for any cataract formation and the best cataract lens to avail, so ask your eye doctor or surgeon the ideal surgery procedure and expected cataract treatment cost.
