Presbyopia, also known as eyestrain, is a visual defect that consists of a reduction in the focusing ability of the eye. The problem is located in the crystalline lens, which is the lens that allows focusing, when it loses its natural elasticity and becomes rigid, progressively preventing focusing. Its effects cause a loss of near vision, and those affected cannot approach objects to see them clearly, but rather the opposite: they have to move farther and farther apart. It is a progressive defect, which can be corrected by glasses, contact lenses or even surgery.
Onset of presbyopia
Presbyopia appears after the age of 45 and is very common. Everyone suffers from this problem with the passage of time, although its impact on each person can vary greatly. For treatment, there is an operation that consists of replacing the presbyopic lens with an artificial one that allows vision at all 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 crystalline lens
Phacoemulsification for presbyopia correction is similar to cataract surgery. As mentioned above, the crystalline lens is replaced by an artificial one. This process is performed by microsurgery with 2 millimeters incisions and anesthesia with drops. There are no stitches or punctures, the eye is not covered and you can see through it even after the operation.
This technique is the most experienced, permanent and safe technique available to correct presbyopia. This operation prevents the future appearance of cataracts, which is the most common surgical disease of the eye, and also corrects other defects such as myopia, hyperopia and astigmatism.
