What are cataracts?
A pathology resulting in the clouding of the crystalline lens, it feels like looking through a fogged window.
When the eye is healthy, the light reaches the retina through the lens, focusing is normal, and the images perceived by the brain are clear. When the eye is affected by cataracts, however, the clouding of the crystalline lens partially obstructs the passage of light, which is thus deflected in different directions. This inhibits focalisation on the retina and the images perceived by the brain become blurred.
What are the symptoms of cataracts?
The development of cataracts is generally gradual and painless. It can occur in both eyes at the same time, but usually affects one eye before the other.
The most common symptoms are blurred vision, difficulty making out objects in low light conditions, inability to cope with intense light (glare), and halos around sources of light. Colours become less vivid, and in many cases myopia may occur or degenerate.
Cataracts may affect young people, but they are typically a degeneration of sight due to ageing. The crystalline lens is normally soft, flexible and transparent, but it may harden and change colour with time.
The removal of cataracts as an opportunity.
At SERI – Switzerland Eye Research Institute, thanks to Dr Roberto Pinelli’s experience, cataracts are removed with refractive lensectomy surgery, thus becoming an opportunity to eliminate not just cataracts, but also a whole range of visual defects, such as myopia, astigmatism, hyperopia and even presbyopia, in a single bilateral operation. A real anti-ageing treatment!
