The lenses have one focusing power. This means they sharpen either your distance, mid-range or close-up vision. most people need it for far vision but still will require glasses for reading.
The lenses contain multiple focal point which helps patients with near and distant vision. It reduces the patients 'need for glasses or bifocals. One shortcoming is that some patients may notice rings or halos around lights, like when driving at night.
Trifocal IOLs have three focal points, providing vision correction for near, intermediate, and distant objects.
It improves the patients’ reliance on glasses as it covers a wider range of vision. Halos and glares can still be present especially in low-lighting.
EDOF lenses contain one long focal point that expands your corrected range of vision and depth of focus. These lenses give excellent distance vision along with improvements in mid-range vision. You may still need to use glasses for close-up tasks like reading. glasses for close-up tasks like reading. EDOF IOLs aim to provide a smooth transition between near, intermediate, and distant vision, potentially minimizing visual disturbances like halos and glare.
Toric IOLs are designed to correct astigmatism, These lenses improve how light hits the retina, allowing you to have a sharper, clearer vision. Toric lenses are available in monofocal, multifocal, extended depth of focus (EDOF) or accommodative models.
