1. Monofocal lenses
These are the standard lenses used in cataract surgery. These lenses are designed to provide a high quality single vision and the surgeon usually selects lenses to provide distance vision which means patients needing glasses for intermediate and near visions.
2. Multifocal Lenses
The first non-rotating symmetric multifocal IOL the Mplus HD lens is designed to produce good distance, intermediate and near vision. The Mplus HD lens has advantages over other multi lenses currently available as it provides good near and far vision in different lighting conditions independent of the pupil size as well as reduced glare/halos/contrast disturbance.
3. Extended range Lenses
Tecnis Symfony lenses are designed to provide an extended range of vision for the patients with lower incidence of post-operative haloes or glare compared to the multifocal lenses.
4. Toric lenses (for astigmatism)
Toric lenses are lenses specially made to correct astigmatism. Astigmatism is a common condition of the eye that causes blurred vision. It occurs when the cornea is not a perfectly curved shape i.e. resembling a rugby ball lying on its side rather than a football. Most people have a small amount of astigmatism which can be corrected by careful planning of the corneal incision during surgery. Approximately 10% of the population have higher astigmatism and will benefit from custom ordered toric lenses.
5. Rayner T-flex Aspheric Toric IOLs (573T and 623T)
This range of lenses are designed for patients with severe astigmatism and those with a history of corneal problems including keratoconus (degenerative changes to the cornea), corneal grafts and corneal scarring.
