Presbyopia, also known as tired eyesight , is a visual defect that consists in reducing the focusing ability of the eye. The problem is located in the lens , which is the lens that allows the focus, when it loses its natural elasticity and becomes rigid, preventing the focus from progressively. Its effects cause a loss in close vision, and those affected can not approach the objects to see clearly, but quite the opposite: they have to separate more and more. It is a progressive defect, which can be corrected through glasses, contact lenses or even surgery .
Presbyopia appears from 45 years of age, and is very common. All people suffer from this problem with the passage of time, although their impact on each one can vary a lot. For the treatment, there is an operation that consists of the substitution of the présbita lens for an artificial one that allows the vision in all the distances. With this operation the effect is permanent, no progression of presbyopia will be created and the patient will no longer need corrective lenses.
Phacoemulsification of the lens
Phacoemulsification for the correction of presbyopia is similar to the operation of cataracts. It is replaced, as mentioned above, the crystalline lens by an artificial lens. This process is performed through microsurgery with some 2 mm incisions and anesthesia with drops. There are no stitches or punctures, the eye is not covered and you can see it even recently operated.
This technique is the most experienced, permanent and safe that exists to correct presbyopia. This operation prevents the future appearance of cataracts, which is the most common surgical disease of the eye, and also allows correcting other defects such as myopia , hyperopia and astigmatism .
