Cataract Surgery: Choosing Your Advanced Technology Lens

Wednesday, March 18, 2020

Unlike traditional cataract surgery, laser cataract surgery offers advanced technology lenses for better sight. Thomas Eye Group in Atlanta is proud to offer the FDA-approved CATALYSTM Precision Laser System which represents a breakthrough in cataract surgery in Georgia and beyond. For the past several decades, cataract surgeons have used handheld instruments to perform some of the most challenging parts of the procedure. Today, the new technology offered by CATALYSTM combines a femtosecond laser, 3D imaging, sophisticated software and several other innovative features that make the cataract procedure highly customized, gentle and more precise than manual surgery.

Intraocular Lens (IOL) Options

Intraocular lenses come in a variety of materials and designs. Your Thomas Eye Group cataract surgeon generally chooses a lens made of a material that is best suited to your individual situation. You may be considering surgery to replace your eyes natural lens with an artificial lens for better vision. This may be because you have a cataract or because you want to be less dependent on your glasses or contacts. There are many different lenses to choose from called Intraocular Lens. An IOL is implanted permanently in your eye and allows light to pass through and focus properly on the retina, restoring your clear vision.

  • Monofocal Lens:​ This is the most commonly used lens. It provides clear vision at one range without glasses or contacts. Most people choose to have their mono focal lens set for clear distance vision. This usually allows you to do things like drive or play gold without needing glasses or contacts. Keep in mind that with a monofocal lens set for a distance vision you will likely need to wear glasses when reading or when doing close work.
  • Monofocal Lens with Monovision​: Mono vision is when one eye’s lens is set for good distance vision while the other is set for good vision close up. Your dominant eye is usually the one corrected for distance vision. Despite having a different focus, both eyes work together for clear vision at both distances. With Monovision, the eye that sees distant objects clearly will see close objects as blurred. The brain learns to adapt to using one eye or the other. If you are considering this option, your doctor may recommend trying it with contact lenses first to see how well you adapt. It usually takes about two weeks to determine if this is the right option for you. This is usually paid for by insurance as a part of cataract surgery.

Premium or Enhanced Lenses

  • Multifocal Lens:​ This lens provided clear vision at more than one distance. A multifocal IOL has focal rings that allow you to see clearly at both near and far distances. This means you can be less dependent on reading glasses. With a multifocal IOL your brain learns to automatically select the focus you need for the activity you are doing. It may take a little time to adjust to this way of seeing. For instance, you will need to learn how far away from your eyes to hold a menu or book but as you adjust you may find you need reading glasses less often.
  • Accommodative Lens:​ This lens also allows you to see clearly at both near and far distances. An accommodative IOL is designed to move or change shape like the eye’s natural lens. Most people find they don’t need glasses or contacts after surgery. However, some people might still prefer to wear glasses for long periods of reading or close work.
  • Toric Lens:​ For people with astigmatism, there are Toric lenses. Toric IOL is designed to correct the blurry or distorted vision caused by your astigmatism. It helps to focus light more effectively on the retina. It may significantly improve your distant vision.
