What is Cataracts?

21:53 - 4 May , 2021


It is an eye condition in which the eye’s lens tissue becomes opaque, making it difficult to see by making it cloudy and blurry.

In a high percentage of cases, cataracts have a slow evolution, so in their early stages they do not represent visual disturbances, but as the disorder progresses, it affects the visual capacity to a greater extent, making a surgical procedure essential to eliminate them and regain normal vision.

Many times, cataracts are usually the result of age or an injury that damages or transforms the eye tissue, as well as the effect of diseases such as diabetes and arthritis, or prolonged intake of corticosteroids.

They usually develop in both eyes, but their degree of progress is variable, so the visual capacity of one and the other is different.

Cataract classification:

  • Congenital: of genetic origin or as an effect of certain diseases such as rubella.
  • Nuclear: affects the center of the lens.
  • Cortical: appears at the edges of the lens.
  • Posterior subcapsular: develops on the back of the lens.

Diagnosis and treatment Cataracts

Once your ophthalmologist analyzes your symptoms and clinical history, he or she will perform a comprehensive eye exam where your visual acuity will be measured and will observe in detail the morphology of your eyes (including the retina and the lens) with a special microscope called a slit lamp.

The treatment indicated for cataracts that do not seriously affect vision is the use of prescription glasses, but if your case is serious and the cataracts do not allow you to see properly, hindering your daily activities, the only alternative is surgery.

There are several types of surgery depending on your specific case, the degree of progress, and the type of cataract. Your ophthalmologist will tell you which one is the most suitable for you.
