Refractive surgery with intraocular lenses

Intraocular lens implantation is a procedure that has been growing in recent years for the surgical correction of refractive errors. In fact, new models are constantly appearing, which we offer as forerunners with all guarantees for our patients, once their good results have been shown in clinical studies, which we participate in at the Miranza clinics.

• Phakic lenses: We place them between the cornea and the crystalline lens; thus, as they do not replace any eye structure, they are a reversible procedure. They are usually indicated for younger patients.

Moreover, depending on the focus provided by these lenses, we can also talk about:

• Monofocal lenses: they correct one single focus, as they are optimised for near or far vision. They are specially used in young patients that have no other visual problems, apart from their refractive error.
• Trifocal lenses: allow you to see well both near, intermediate and far. They are usually recommended in older patients, with presbyopia or cataract.
• Extended-focus lenses: They have appeared more recently and increase the depth of focus compared to monofocal lenses, while avoiding some of the disadvantages that can be associated with trifocal lenses (such as halos, glare or loss of contrast).

Finally, there is another classification, depending on the refractive error that it is corrected:

• Standard lenses: they correct myopia, hyperopia or presbyopia.
• Toric lenses: besides, they also correct astigmatism.

Technological progress has not only allowed the introduction of new lens designs, but also more accurate equipment to calculate their power in each case and intelligent platforms in the operating room that allow their perfect positioning in the eye.
