The patient who has cataracts has an opacified lens and where to get contacts today. Over time, this opacity becomes more intense, causing vision to become increasingly blurry. If not treated, the cataract can lead to blindness, which is reversible with surgery. In this article, see which lens models can be used in cataract surgery and understand the particularities of each one. Cataract surgery at the most affordable prices
What Are The Types Of Lenses For Cataract Surgery?
Two main types of lenses can be used in cataract surgery: rigid and flexible.
With the evolution of surgical procedures for cataract removal, rigid lenses were left aside to be replaced by flexible ones. These are more malleable and can be bent, making the surgery cut smaller. But in addition to the texture and malleability of the lenses, different models help correct various ophthalmological problems.
Flexible lenses are available in single-vision, non-Toric, and multifocal Toric or non-toric models in clinics like discover vision centers for example. Understand a little more about each model.
Toric Monofocal Intraocular Lens
Indicated for patients affected by astigmatism with medium/high degrees, toric mono-focal intraocular lenses have curvatures calculated to correct astigmatism, which helps the patient greatly reduce dependence on “far away” glasses.
Despite correcting the distance vision, after the cataract removal procedure, it is common for the patient to need glasses still to improve their close vision.
Monofocal Non-Toric Intraocular Lens
These lenses are usually indicated for patients who do not have a high degree of astigmatism, usually below 1. Monofocal non-toric lenses are mainly used to correct low-degree myopia or hyperopia of up to 6 degrees.
As with the toric mono-focal lens, this lens does not preclude the possibility that the patient may need near-vision glasses after cataract surgery.
Toric Multifocal Intraocular Lens
Multifocal lenses are considered the most modern, as they have focus points for both far and near. Therefore, they are the most suitable for patients who want to correct both problems simultaneously.
The toric multifocal lens is indicated only for patients who have medium-grade astigmatism. However, the patient will still need to wear glasses in some situations.

Multifocal Non-Toric Intraocular Lens
Also indicated for patients who wish to correct far and near ophthalmic problems, non-toric multifocal lenses are recommended for patients with low-grade astigmatism. However, the patient will still need to wear glasses in some situations.
Accommodative Multifocal Intraocular Lens
Accommodative multifocal lenses are models that seek to imitate the natural anatomy of the crystalline lens; that is, they simulate the movement of accommodation of the eye’s natural lens and adapt to focusing far or near as the ciliary muscle moves them.
