Cataract Surgery: Choosing Your Advanced Technology Lens

Wednesday, March 18, 2020

A cataract is a clouding of the natural lens inside the eye, resulting in vision loss that cannot be corrected with spectacles, contact lenses, or corneal refractive surgery (including LASIK). Cataracts are very common; greater than 50% of all Americans age 80 or older either have cataracts or have had surgery to remove cataracts according to the National Eye Institute. Recently, there has been a trend toward performing cataract surgery in younger demographics, especially given the advanced optics available. However, one of the most important decisions you will have to make before your cataract surgery is what type of intraocular lens to choose.  



Thomas Eye Group in Atlanta is proud to offer a wide-range of lens options, including cutting-edge laser cataract surgery via the FDA-approved CATALYS Precision Laser System. Unlike traditional cataract surgery, laser cataract surgery offers advanced technology for better vision and is a true breakthrough in cataract surgery. For the past several decades, cataract surgeons have had to rely solely on handheld instruments to perform this challenging procedure.


Intraocular Lens Examples


However, the sophisticated software that the CATALYS offers helps facilitate this procedure by allowing for true customization by optimizing outcomes and helping treat corneal astigmatism. In combining a femtosecond laser and 3D imaging with several other innovative features, the CATALYS is among the most precise cataract surgical options available today.

Intraocular Lens (IOL) Options

Intraocular lenses come in a variety of materials and designs. Your Thomas Eye Group cataract surgeon will help you select the most appropriate lens that is best suited for your individual needs.

  • Monofocal Lens:​ This commonly used lens provides clear, single-range vision and most people choose to have their monofocal lens set for distance. This allows individuals to perform activities such as driving or playing golf without requiring them to wear glasses or contacts. However, with a monofocal lens set for distance vision, individuals will likely still need to wear glasses while reading or for activities involving close vision.
  • Monofocal Lens with Monovision​: Monovision is when one eye’s lens is set for distance and the other is set for near vision. Despite having different focal points, both eyes work in tandem for clear vision at both distance and near. If you are considering this option, your doctor may initially recommend a contact lens trial to determine if this is your best option.

Premium or Enhanced Lenses

  • Toric Lens:​ For candidates with significant corneal astigmatism, toric lenses are available. Toric IOLs are monofocal lenses designed to correct the blurry or distorted vision caused by your astigmatism and may significantly improve your distance or near vision.
  • Multifocal Lens:​ A multifocal IOL has focal rings that allow you to see clearly at both near and far distances.  With a multifocal IOL, you will have maximum flexibility with the least amount of dependence on glasses for any focal point.

David J. Sackel, M.D., one of Thomas Eye Group’s cornea, cataract, and refractive surgeons, often uses this advanced technology to help his patients achieve their desired outcome:


“Many of my patients who are active and enjoy playing sports have gravitated toward using the femtosecond laser and the advanced optics of the multifocal IOL. Not only does this lens enable them to be less dependent on glasses for both distance and near, but it also provides them with greater depth perception.”
