New advances in cataract surgery – mono and multifocal intraocular lenses.
Cataract surgery (cataract phacoemulsification) is currently the only treatment for this condition.
Thanks to a technique that is increasingly safe and comfortable for the patient, the current trend is for patients to undergo surgery earlier and earlier, as there is no justification for delaying excessively the moment when quality of life improves..
The surgery essentially consists of removing the crystalline lens (which has become more opaque than normal) and which is nothing more than a natural lens, which has approximately 21 positive dioptres, and replacing it with an artificial intraocular lens.
Cataract surgery is now performed, with very few exceptions, under local anaesthesia and on an outpatient basis.
The technical innovations essentially consist of the types of intraocular lenses used.
Monofocal lenses, which are generally the most widely used, are normally designed for distance vision, so it is necessary to wear spectacles for near vision and, if necessary, spectacles with small corrections for distance vision.
Multifocal lenses allow you to see both far and near without the need for any kind of glasses.
In most cases, the use of near or far glasses is necessary only in specific situations and requires
that the distance graduation is exactly right. If this is not the case, it will be necessary to “correct” the graduation.
