Transparent crystalline lens surgery with intraocular lens implant: monofocal (monovision), multifocal (bifocal/trifocal) or accommodative 22/03/2013

Surgery for presbyopia includes different techniques depending on the age, correction required and characteristics of the eye. Each case is evaluated via a series of tests that help us decide the most suitable technique for each patient.

Although many projects are being developed to treat presbyopia, the only definitive treatment currently available for its correction is extraction of the crystalline lens which is, due to the age-related loss of accommodation, the cause of the appearance of presbyopia. The lens can be replaced with a monofocal (monovision) lens or by multifocal (bifocal/trifocal) lenses.

Of all the techniques being used to correct presbyopia, at the Institut de la Màcula we recommend replacing the transparent crystalline lens with a multifocal lens implant (bifocal/trifocal) or a monofocal lens with monovision, or advanced monovision, as these are the safest, most stable, effective and definitive methods available today.

Surgery using multifocal lens implants is the most widely used to correct presbyopia. This surgery replaces the transparent crystalline lens with another that allows the patient to focus without the need for glasses, both in distance vision and middle distance and near vision. An evaluation prior to surgery determines the most suitable lens for the patient, which will depend on the characteristics of the eye and the person's visual needs.

This surgery is stable and does not require any further operations. Moreover, the crystalline lens is removed, it also avoids the need for cataract surgery in the future.
