The crystalline lens that stops being ... crystalline, and "fogs" your sight
With age, our eyes also experience changes that sometimes end up affecting vision. It is what happens with a small disc inside your eye called “lens”, which can “fog up”, turning yellowish and causing what is known as a cataract.
A cloud over your eyes
In most cases, cataracts are easy to diagnose, easy to solve, fast and effective.
At first, cataracts cause a sensation of glare, and are accompanied by a slow and progressive decrease in vision, which appears cloudy, unfocused, blurred, and does not improve when changing glasses, perceiving a kind of dye or yellowish coloration as if we were looking through a dirty window. The loss of tonality or attenuation of the colors gives us a dull vision.
Who is affected?
Cataracts affect more than 60% of those older than 75 years. Researchers do not know for sure why these changes occur in the lens. In addition to age, there are other factors that also influence its appearance:
- People with family backgrounds
- Hypertensive patients
- People with high levels of glucose and cholesterol
- Consumption of tobacco and alcohol
- People who have undergone continuous treatments with corticosteroids
- People exposed to continuous ultraviolet light (sun exposure)
- People with malnutrition.
There are no drugs that have a proven efficacy. The only effective treatment is surgical. To undergo this procedure it is recommended that the vision should not be excessively bad before the intervention; Seeing as, in these cases, the recovery may not be adequate, especially in elderly people.
That is why it is recommended not to wait for the vision to be disabling and for difficulties to begin in the day to day that affect driving or there is a very intense deficit.
Currently, cataract surgery allows an almost immediate recovery, since the placement of an intraocular lens in the place that occupied the lens, provides an image of excellent quality with very little distortion
The intervention is quick, simple, and painless and with few risks. It is usually performed on an outpatient basis, with local anesthesia and has a very high success rate (95 percent of the patients recover their visual acuity).
