They correct 90% of presbyopia. For some activities, glasses should be used to see up close.
Besides replacing cataracts, these lenses correct presbyopia.
You must practice bilateral.
Phacoemulsification with bifocal or multifocal lens
Astigmatism requires additional laser treatments or a multifocal toric lens.
Phacoemulsification with toric lens
Corrects cataracts and astigmatism.
The toric bifocal corrects cataracts, presbyopia, and astigmatism.
Lens is fixed to the iris.
They are made of PMMA (polymethylmethacrylate). Rigid folding
For people over 18 years old.

Myopia > 6.0 d. depending on corneal thickness.
Hyperopia > of 5.0 d.
Astigmatisms > of 5.0 d.
