Presbyopia or tired eyesight is a natural condition in all human beings. It consists in the gradual loss of the eye's ability to focus on objects up close. The focus is made through a change in the shape of the lens. With age, the crystalline lens begins to lose its elasticity, which progressively reduces the ability to focus. Presbyopia usually starts at age 45 and progresses slowly until age 55. Presbyopia is manifested by the need to move objects away to focus them better. A point arrives that neither moving away the objects can see them clearly, at this moment corrective lenses are necessary. The presbyopia supposes a greater dependence on the glasses and in some situations neither with glasses nor without them the necessary tasks can be carried out, in this case other solutions are necessary. Contact lenses provide a more natural vision than glasses but have the disadvantage of daily replacement and cleaning and are not without risk.
The alternatives to glasses or contact lenses are the Multifocal Vision and the Combined Laser Vision.
- Multifocal vision.
Presbyopia arises as a result of a progressive loss in the elasticity of the lens, it is then logical that the lens replacement is the most appropriate option for the management of presbyopia. We call this procedure Multifocal Vision, it consists of replacing a natural lens called a crystalline lens with an artificial lens that we placed in the same place as the lens. The lens is aspirated by microsurgery with an ultrasound emitting system. The lens we use is a latest generation diffractive microlens, advances in nanotechnology allow an exclusive design of the lens. The microsurgery techniques allow a quick rehabilitation, first we operate one eye and one week the other.
- Combined Vision.
The combined vision takes advantage of a natural phenomenon, ocular dominance. Dominance is that there is one eye that dominates in far vision and another that dominates in near vision. In combined vision we enhance this natural effect and focus one eye more far and the other closer, the result is that with both eyes open you will see far and near. If you close one eye each time you will see that one dominates from far and the other closely, the same as before operating but in a much more pronounced way. In the consultation we will reproduce the conditions of the operation so that a more detailed idea of the result can be made.
Your ophthalmologist will tell you which is the most appropriate procedure for your case.
Both treatments are ambulatory and the recovery time is fast.
