👓 Bifocal IOLs (Intraocular Lenses) are a type of lens implant used in cataract surgery to help restore vision at multiple distances. They’re designed to reduce dependence on glasses or contacts.
- How they work: Bifocal IOLs have different zones for near and distance vision, allowing for clearer vision at multiple distances.
- Types: Some common types include diffractive (e.g., Alcon ReSTOR) and refractive (e.g., AMO Array) lenses.
- Benefits: Reduced need for glasses, improved vision at various distances.
- Considerations: Potential for halos, glare, or decreased contrast sensitivity.
