[NEW LENSES IN MODERN CATARACT SURGERY].

During cataract surgery the natural opaque crystalline lens is replaced by an artificial intraocular lens that compensates for the optical loss following lens removal. The conventional intraocular lens is mono-focal and necessarily requires spectacle correction for the clear vision at various foci in the same eye. In recent years a variety of intraocular lenses were developed including multifocal (bifocal and trifocal), "toric" lenses to correct corneal astigmatism, lenses with extended depth of focus and their combinations. Modern cataract surgery not only enables the correction of quality of vision but also enhances quality of life and eliminates spectacle dependence following surgery at all distances; far, intermediate and near.
