A toric IOL is a premium lens specifically for those with astigmatism and requires an additional fee. Toric IOLs may be a good option for patients with significant regular corneal astigmatism. Also known as special astigmatism-reducing lenses, these implants are available in both monofocal and multifocal versions to help reduce dependency on glasses after surgery.
A multifocal IOL is a premium lens and requires an additional fee. Also known as extended-depth of focus or expanded range of focus, these lens implants use concentric optical rings to simultaneously focus light coming from different distances. These lenses have the potential to provide great functional distance and near vision without glasses. However, glare and halos around lights can occur at night. Some patients may experience some loss of contrast sensitivity and images that might not be as crisp compared to the standard monofocal lens option.
Monofocal intraocular lens (IOL)
A monofocal intraocular lens (IOL) is the standard lens included in the single-fee cost. This lens provides excellent binocular distance or near vision when not wearing glasses—but not both. Some patients enjoy the monovision approach with standard monofocal lens implants that result in good distance and near vision without glasses, but some loss of binocular stereo vision can be expected when choosing monovision.
Patients opting for a premium lens will incur an additional fee.
