A Cataract is a clouding of the natural lens of the eye. The lens is located behind the iris (which gives the color of the eye) and is usually transparent. Cataracts develop slowly and usually affect both eyes, resulting in a gradual decrease in vision. Cataracts are the "natural" evolution of the lens after 60 or 70 years.

01 / Symptoms

  • Halos around the light

  • Glare

  • Difficulty driving at night

  • Blurry vision

  • Evolution of myopia

02 / Causes

  • Age

  • Trauma

  • Radiation exposure

  • Congenital

  • Iatrogenic (following eye surgery)

03 / Risk factors

  • High myopia

  • Diabetes

  • Smoking

  • Sun exposure

04 / Prevention

To prevent early onset of cataracts or macular degeneration:

  • Limit exposure to sunlight + wearing sunglasses

  • Food rich in antioxidants (oranges, blueberries, carrots, strawberries, kiwi, etc.)

  • Avoid smoking

To date, cataract surgery is the only effective treatment for cataracts. Many scientists are looking at whether it is possible to cure cataracts with eye drops, but no scientifically proven treatment except surgery is currently available.


In addition to restoring vision lost due to clouding of the lens, cataract surgery can correct myopia, hyperopia, astigmatism and presbyopia with monofocal, toric, or multifocal intraocular lenses.


Cataract surgery can be performed using a Femtosecond Laser (FLACS: Femtosecond Assisted Cataract Surgery) which can improve the safety and accuracy of surgery in specific cases.
