As time passes, numerous people will notice alterations to their vision, but certain cases are more extreme and require replacement of the natural lens of the eye. In order to remove the natural lens they have damaged, people who have developed cataracts can get an IOL, making them suitable for a Symfony or other IOL type.
For people who want to stop using glasses or lenses in the future, a Symfony IOL may be preferable. Depending on their eyesight and eye health, other IOLs could be better choices for certain patients.
The first FDA-approved IOL with an enhanced depth of focus was the Symfony intraocular lens implant, so patients could see from a range of distances.
An important technical accomplishment, the Symfony IOL, was considered an alternative to monofocal lenses. Toric implants for patients with astigmatism are also made by Symfony IOLs.
- The lenses were designed to help patients see well after surgery without needing to use corrective lenses.
- Without the need for glasses or lenses, up to 76 percent of participants who received Symfony IOLs were able to see well at moderate distances, whereas only 36 percent of patients with monofocal implants could do the same.
- With monofocal or Symfony IOLs, patients had almost equal power to see well at greater distances, but there have been some drawbacks to these lenses.
- A greater risk of bleeding, blurry vision or infection is present.
- The ability to tell colors apart (contrast sensitivity) can be decreased, and in darker light or dim environments, like in a fog, this sometimes becomes worse.
- After implants, it is normal for patients to see speckles, halos, or flash.
- For patients undergoing an operation to fix cataracts, IOLs are one of three choices. Cataracts make the lens seem cloudy and make it hard to see. The eye is unable to focus until the cataract-filled lens is replaced properly.
- IOLs for patients who are Eighteen and older have been licensed by the Food & Drug Administration. Putting IOLs is called off-label use in infants, but it is often done. Kids or babies who develop cataracts at a young age often benefit from these lenses.
- Children who have cataract surgery can, in some cases, use glasses or contacts and obtain IOL until they are old enough to undergo surgery.
