An important part of cataract surgery is deciding exactly what you want your vision to be like after it. The surgery involves removing the natural lens of the eye. The lens is where cataracts affect your vision. But you need a lens to see clearly. That’s why during cataract surgery, the
lens is replaced with an artificial intraocular lens. Intraocular lenses are usually made out of either silicone or acrylic materials. Both of these materials are durable enough to last a lifetime while still being flexible. The best part of IOLs is that they are surprisingly customizable. Premium versions of IOLs can be so beneficial to your vision that you may never need glasses again! Keep reading to learn more about the differences between standard IOLs and premium IOLs!
What is a Standard IOL?
A standard IOL is also the most cost-effective option. This is a monofocal lens. A monofocal lens provides vision at one fixed distance. This means that the wearer needs to continue wearing glasses after cataract surgery. Glasses are necessary if they want to see for the distances that their lens isn’t set for. It can be for either far distance, intermediate, or up-close. Many patients do not like the prospect of wearing glasses after cataract surgery, making this less popular. If wearing glasses after cataract surgery doesn’t bother you, monofocal IOLs may be the right choice.
Premium Option #1: Multifocal IOLs
As the name suggests, multifocal IOLs are adept at focusing vision at more than one range. They work based on the same principle as many other adjustable lenses. With a multifocal IOL, different zones of the lens are focused at different powers. The light that passes through those zones focuses onto the retina appropriately.
Premium Option #2: Accommodating IOLs
Accommodating IOLs achieve similar results as multifocal IOLs with a different method. Rather than a light changing property in the design of the lens, this IOL is about movement. Accommodating IOLs move inside the eye using the same muscles that adjust the natural lens. This lends itself to smoother transitions between focal distances.
Premium Option #3: Toric IOLs
Normal premium IOLs typically only correct for people with farsightedness or nearsightedness. Toric IOLs are specifically made for people with astigmatism. Toric IOLs have to be custom fit for each individual, as astigmatism can vary from patient to patient.
Premium Option #4: Aspheric IOLs
Most IOLs are only made in a spherical design. Aspheric IOLs are not spherical. The natural lens is closer to this shape. Having a design closer to the natural lens helps with the appearance of visual aberrations. Above all, when making a decision about IOLs, talk to your eye doctor. They will be able to make a recommendation about what they think is best for your eyes. No matter what IOL you decide on, cataract surgery will change your life for the better!
