Intraocular lenses are part of a refractive surgery known as refractive lens exchange. Refractive lens exchange is also known as RLE. RLE treats people with presbyopia, cataracts, or as an alternative to LASIK.
During RLE, the cornea is opened up, leaving the tissue still attached. This is to allow for quick healing after the procedure.
The lens is then broken apart. This uses either lasers or a process called phacoemulsification.
Phacoemulsufication uses sonic disruption. After the lens breakdown, the pieces of the lens are then removed with suction.
The IOL is implanted and the cornea is then closed. This is all done under the effects of a numbing agent, so there is no pain during a refractive lens exchange.
While the surgery is straightforward, selecting an IOL is an important decision. If you have questions, discuss your IOL options with your eye doctor.
They will be able to explain to you the differences and their recommendation for you. Want to know a little about IOLs before your cataract screening at Takle Eye? Keep reading to learn more!
Monofocal IOLs
Monofocal IOLs are the “standard” option for IOLs. They provide excellent vision, but only for either far vision or close up vision. This means that you will still need to wear glasses after RLE if you get monofocal IOLs.
If you want a multifocal experience using monofocal IOLs, there’s a way. You can try a technique called monovision. With monovision, the surgeon puts a close up IOL in one eye and a far away IOL in the other.
Most patients find that after a short time, they are able to switch eyes depending on the distance away. Not everyone’s brain can handle this switch.
If you find that monovision isn’t working for you, you can always go back and switch to a different IOL. Changing IOLs isn’t something that’s encouraged, but it is possible and safe.
Multifocal IOLs
The first of the “premium” IOLs, multifocal IOLs allow vision at both near and far distances. They resemble bifocal lenses and operate in a similar fashion.
Certain parts of the IOL focus at different distances. Multifocal IOLs are quite popular, but are not the only premium option available.
Accommodating IOLs
Accommodating IOLs also allow you to see both near and far. With accommodating IOLs, they move around the eyes in a smooth and natural way.
They are specifically designed to be as close to the natural lens as possible. This allows your eye to focus seamlessly, at all distances, without feeling unnatural.
There are even more IOL options out there for you to experience. Want to choose the best IOL for you? Schedule an appointment at Takle Eye Group in Griffin, Georgia today!
