One of the most important aspects of Cataract Surgery is the implanting of the Intra-Ocular Lens (IOL) as a substitute for the eye’s cloudy natural lens.
There are different types of IOLs that can be implanted into the eye and each of them presents different capabilities. You should know their differences to be able to discuss the most appropriate one for you with the eye doctor.
The IOLs available for Cataract Surgery are Multifocal, Monofocal and Toric lenses.
While the different IOLs have their pros and cons and all serve their purposes well, the most recommended and preferred lens is Multifocal.
Multifocal IOLs are tiered lenses that enable patients to see clearly at both near and far distances.
Contrary to Monofocal and Toric lenses wherein a patient is still required to wear eyeglasses, multifocal enables patients to not rely on spectacles.
Multifocal IOLs are designed to allow clearer sight at near, intermediate and far distances. They are made up of concentric rings of varying optical power, each of which refracts, or bends incoming light, bringing it into focus at different points simultaneously.
With Monofocal, vision is typically in focus at only one distance, near, intermediate or far.
Toric lenses are used in patients who have more than 1 diopter of astigmatism. These IOLs may either be Monofocal or Multifocal.
Also, Toric lenses are considered premium intraocular lenses that aside from correcting astigmatism, also corrects nearsightedness and farsightedness. When Toric IOLs are implanted in the cataract procedure, they are rotated so the markings on the IOL are aligned with the ones on the cornea to assure proper astigmatism correction.
Each IOL has its own purpose. Choosing the right one for your boils down to the doctor’s recommendation and your personal preference as well.
