When the natural lens becomes cloudy with the passage of time, this is called cataract.
During cataract surgery, the natural lens is removed and replaced with a clear plastic lens.
This new lens is usually monofocal, and is best able to focus light on the retina from one distance.
Spectacles are then required to see clearly at other distances. Usually, patients like to see clearly in the distance and use spectacles for intermediate (computers, painting, sheet music) and near (reading) work. However, there are some exceptions.
Many people now prefer to receive a multifocal lens implant. This provides good distance vision and a greater ability to read without glasses than is the case with a monofocal lens. Whilst many patients are candidates for multifocal lens implants, this is not the case for all patients. Your particular requirements and suitability will be discussed in detail at your consultation.
