A focusing lens implant is typically placed in the eye at the time of cataract surgery. Insertion of a Monofocal lens is standard practice. Unfortunately a standard monofocal lens will not correct astigmatism, nor provide good depth of focus with a clear image at near, intermediate and distance. A variety of “added value” Premium lenses are available and include:
- Monofocal Toric Lens – to correct astigmatism
- Multifocal Lens – to correct distance, intermediate and near
- Multifocal Toric Lens – also corrects astigmatism
Monofocal Toric Lens
This is a lens that corrects astigmatism in those who have a high amount. Like an astigmatic spectacle or contact lens, astigmatism correction is built into the implant. The lens implant which needs to be specially ordered, is inserted into the eye and accurately positioned at a specific astigmatic angle. This implant provides patients with good vision correction at distance. For near and intermediate vision, glasses are usually necessary.
This exciting implant reliably corrects distance, intermediate and near vision, reliably eliminating the need for glasses altogether. Some patients need to go through a period of adaptation – and have to get used to using the lenses.
Multifocal Toric Lens
For those who have large levels of astigmatism (1.75D or more), a toric lens is required. Fortunately these are also available with Trifocal lenses and have to be ordered specially for each individual eye. Like the monofocal toric, the lens implant has to be placed in the eye at the correct angle to neutralise corneal astigmatism. The lenses reliably provide spectacle freedom for distance, intermediate and near vision.
