Monofocal Intraocular Lenses (IOLs): Restoring Clear Vision After Cataract Surgery
Schedule your eye exam today!
How Monofocal IOLs Work
These lenses focus light at a single focal point. The focal distance is chosen based on lifestyle, and glasses may still be needed for other ranges.
The lens power is set for one clear focus point, reducing dependence on glasses at that range.
Glasses are usually needed for close work if lenses are set for distance, or vice versa.
What to Expect During Cataract Surgery
Cataract surgery with monofocal IOLs is an outpatient procedure performed under local anesthesia. The process is quick, and most patients return home the same day.
The surgery usually takes 15 to 30 minutes per eye.
Numbing eye drops are used so there is no discomfort during surgery.
The cloudy lens is removed through a tiny incision.
The new monofocal IOL is placed securely inside the eye.
Most people go home the same day after a short recovery period.
