What is a cataract and how to correct it?

CataratasCataract remains the more common cause of low vision and blindness in the world, especially in developing countries.

They are produced by progressive opacification (mainly due to aging) of the crystalline lens, which is the natural lens of the eye that normally is transparent and helps focus the image on the retina.

Between 60% and 70% of the population over 65-70 years have some form of cataract and cataract surgery is the most frequently performed operation in this age group.

Unlike other diseases like glaucoma or diabetic retinopathy, it is a cause of blindness that can be fixed.
The main indication for surgery is the loss of quality of life resulting from vision loss that occurs, when it affects daily living activities such as driving, reading, etc.

Nowadays, thanks to the techniques like local and topical anesthesia, advanced phacoemulsification, minimal incisions without sutures and foldable intraocular lenses (even multifocal ones), it is possible not only to restore vision after a cataract has arisen but also to eliminate previous shortcomings as nearsightedness, farsightedness, astigmatism or presbyopia or eye strain, improving the quality of life of the patients.
