Monofocal lenses provide good sight correction for one distance (usually in the distance) and have always been the standard implant for cataract operations. However, the patient will still need glasses for close and medium vision.
The very latest solution is a multifocal implant lens which provides good vision for all distances. These lenses last a lifetime.
Recent improvements to monofocal or multifocal implant lenses are:
- lenses with a yellow filter to protect the macula
- aspheric lenses for better contrast vision at night
- toric lenses to correct astigmatism.
