Standard Artificial Lens Implants
These lens implants were developed in the 1950s and are, historically, the most commonly implanted lens. These tried and true lens implants focus light at a single distance and are usually selected to provide good distance vision. As these lenses do not focus at near, it is still necessary to wear reading glasses after surgery and it is usually necessary to wear glasses for intermediate activities, such as computer use. Newer intraocular lenses are designed to reduce the need for reading glasses after surgery.
In addition, standard artificial lenses do not correct astigmatism, and for patients with significant astigmatism it will still be necessary to wear glasses for both distance and near vision after surgery. For patients with astigmatism who wish to reduce their need for glasses after surgery, a toric lens implant may be a better option.
