Trifocal intraocular lenses (IOL's)
are an advanced solution that can provide sharp vision at all distances without the need for glasses after cataract or lens exchange surgery. If you have astigmatism, a trifocal toric lens can be implanted to simultaneously correct astigmatism, with the same lens.
Monofocal intraocular lenses (IOL‘s)
can provide sharp vision at only one distance. Clear vision is usually set for far distance and glasses are needed for intermediate and near vision tasks. If you have astigmatism, a monofocal toric lens can be implanted.
