The essential feature of eye lenses is their transparency. A cataract is a condition in which the eye lenses are blurred or clouded. Cataract obviously interferes with vision and in 99.99% of cases, the natural eyes lenses would be replaced by artificial lenses or intraocular lens. This procedure is called a Cataract surgery, which is a very common surgery, with a 97 % to 98 % success rate.
Who needs Cataract surgery?
Cataracts are partial or complete opacifications of the eye lenses. Therefore, the eye lenses must be replaced with an intraocular lens during surgery. In the case of cataracts, the patient would experience a decrease in visual acuity especially the far vision, which can be troublesome in everyday life, such as driving. Anyone, over 18 years old, and in some cases at a very young age, can benefit from this surgery. For people over 60, there is a 50% chance of developing cataracts. To this day there has been no other effective medical treatment for this condition and the only option would remain surgical.
What causes caracats? ( Caracts causes)
Senile cataract is a type of Cataract that appears spontaneously and gradually with age, after 60 to 70 years. However, certain factors can trigger the senile Cataract, such as trauma, prolonged exposure to ultraviolet rays, smoking, heredity, diabetes, and certain metabolic diseases, etc.
Hereditary cataracts, on the other hand, may develop even in young children. Depending on the extent of the opacity of the lens, even at an early age, cataract surgery is recommended.
It should be noted that Cataract is one of the leading causes of blindness.
Cataract surgery procedure
If both eyes have developed cataracts, the surgery will be conducted on one eye, and after a few days on the other one.
Local anesthesia suffices it for cataract surgery and allows obtaining the immobility of the eye. It should be noted that the intraocular lens does not restore near vision. After the surgery, the normal optimal distance vision is obtained (10/10) and there would be no need for glasses.
