Types of cataract operation
There has been much talk about the cataract surgery, but little of the surgical techniques for cataract surgery that exist today.
That is why here we explain the types of cataract operation that exists today as well as types of lenses that are implanted.

Phacoemulsification
La phacoemulsification cataract operation is technique for cataract surgery is the most conventional. Use the use of ultrasound to aspirate the cloudy lens (cataract) and is currently the most widely used technique.
Bimanual microincisional technique
La MICS surgery (Micro Incisional Cataract Surgery) is a similar technique but it is done with micropulsed ultrasound, also called facofrío, because it does not generate heat and allows the surgery through smaller incisions that in conventional phacoemulsification, we went from 2 mm to 5 mm.
This technique allows the biweekly intervention, with hydrodynamic systems that reduce intraocular trauma, getting greater efficiency and greater safety. He result final is a faster recovery from the patients.
It is currently the preferred technique to perform the bilateral surgeryintervening both eyes in the same surgical act, as if it were a refractive surgery, where the patient regains vision faster, especially in cases where they are implanted mulitfocal lenses. The ideal platform for this type of surgery is Alcon's Centurion equipment.
Laser cataract surgery
LACS (Laser Assited Cataract Surgery) It is the most modern technique for cataract surgery.. She combination of laser and ultrasound. He femtosecond laser It makes the incisions, the opening of the capsule (capsulorhexis) and helps emulsification, facilitating its aspiration by ultrasound. This technique gets greater security, especially when posed with refractive purposes, with the implantation of multifocal lenses.
The best combination would be to use the femtolaser together with micropulsed phaco, using the MICS bimanual technique, with the Alcon Centurion platform.
Types of intraocular lenses
Whenever a cataract is removed, the lens must be replaced by an artificial lens, and as a result of the intervention the patient will enter pseudophakic state.
These are the main types of lenses used in cataract surgery.
Monofocal lenses
All the monofocal lenses are lenses with a graduation, usually for the far vision. This graduation allows you to see well from afar but you will need glasses for medium distance and near. Are the Most used IOLs and are covered by mutuals.
Bifocals and multifocals
All the bifocal and multifocal lenses are lenses with refractive or diffractive type geometries, that generate various spotlights main, 2 in the case of bifocals (far-near) and 3 in the case of multifocals (far, medium distance and near), which is why these lenses are also called trifocals.
All the Trifocal IOLs are currently the most widely used.
Extended focus lenses
All the Extended Focus lenses, also known as EDOF (Extended Deep Of Focus). They are the most recent and their objective is minimize side effects generated by multifocal IOLs in some patients, generally glare y halos Around the lights
In Europe they have not finished triumphing, because the next vision is not entirely good, however, new mixed models that combine technology have appeared EDOF with the multi-locality nicknamed and it does seem that they provide advantages, especially in cases in which a previous refractive surgery was performed and at the beginning of presbyopia do not want to wear glasses.
Toric lenses
All the toric lenses they are lenses that allow correct astigmatism and combine with monofocal lenses (toric monofocals), toric multifocals y Toric EDOF.
