“Specialty lenses (multifocal/toric) for cataracts, which aim to reduce glasses dependence, carry a higher risk of side effects like halos, glare, and reduced contrast sensitivity compared to standard lenses. While generally safe, they may require longer neuro-adaptation and are not suitable for patients with specific underlying eye conditions.

Key Considerations
Visual Side Effects: The primary "complication" with premium/specialty lenses is the increased likelihood of experiencing halos, rings around lights, or glare, especially at night.
Contrast Sensitivity: Some, particularly multifocal lenses, may cause a loss of contrast sensitivity, making it harder to see in low-light conditions.
Adaptation Period: It can take several months for the brain to adjust to the new way of seeing with these lenses.
Patient Selection: These lenses are not ideal for everyone; for instance, they may not be suitable for those with existing corneal irregularities, like macular degeneration or, in some cases, severe astigmatism.
Standard Lens Stability: While standard (monofocal) lenses have fewer of these specific side effects, they often require glasses for near or intermediate vision.

Both types share risks of standard surgery, such as infection or posterior capsule opacification (secondary cataracts)”
