The lens is a part of the human eye with a lens shape that is located behind the iris and in front of the vitreous humor. Its main function is to focus on objects at different distances. When the lens deteriorates, what is known as tired vision occurs.



Tired vision (or dysfunctional lens syndrome) starts at age 45 and begins with a progressive loss in the ability to focus closely, to the point that glasses are needed. The next phase of the SDC causes a reduction of the contrast vision, an alteration of colors and abnormal visual phenomena, including photophobia. In the third phase, cataracts occur and transparency is progressively lost.

There are many operations for eyestrain. In our clinic, the vast majority of patients are operated with multifocal lenses, the technique that we consider most appropriate and permanent. The procedure consists of replacing the crystalline lens with an artificial one of high technology. The operation is called phacoemulsification and is performed by ultrasound. Thanks to nanotechnology, it is nowadays a safe and stable technique.



Not all patients with dysfunctional syndrome can be operated. To evaluate each case, a previous study must be carried out in which various functions of the eye are analyzed to confirm the safety of the operation. According to the results of this study, it will be determined if the operation is feasible and, if so, which is the most appropriate technique for the specific case.

On the other hand, the operation also has to be a decision of the patient himself, since the tired eyesight can also be corrected with glasses or contact lenses. The dysfunctional lens syndrome can be operated in any of its phases and the operation definitely stops the deterioration process. Although there is no progression after the operation, the appearance of cataracts in the future is avoided in this way.


Procedure and postoperative

The operation lasts less than 10 minutes. Both eyes can be operated simultaneously or on different days. The recovery is very fast and, when leaving the operating room, most of the patients already notice an important advance, being able to see by the operated eye at once. Vision is not lost at any time and the only precaution that the patient must take is rest in the case of feeling fatigue or using artificial tears if the vision is fixed for a long time.

Even so, in some cases, especially in patients with astigmatism, the recovery can be delayed and sometimes it is necessary to make an adjustment with the laser after a few weeks of the operation.
