A standard, mono-focusing lenses that provide ideal distance vision, allow post cataract
patients to see clearly at distant vision and often restoring their vision to
pre-cataract state. However, most patients will still require spectacles for reading or
distant vision if cornea astigmatism is present.
Toric lenses can correct many level of astigmatism. In the same way that spectacles are
made to correct astigmatism. Toric lenses correct both cataracts and pre-existing cornea
astigmatism. These lenses have extra power in one specific region in the lens. They
deliver preciseness and quality vision for cataract patients with cornea astigmatism.
However, although they can improve distant vision and astigmatism, you may still need to
wear glasses for all near tasks, such as reading or writing. In these situations,
multifocal toric lenses will benefit.

Multifocal lenses provide excellent quality vision for near, intermediate and distant.
As we age, the ability of our eyes to change focus during different range of vision
weaken, eventually we will rely on reading glasses during near to intermediate reading.
Through progress in technology, highly specialized optics is able to diffract light and
bring it to focus at more than one point to allow excellence vision from near to distant
range. It is due to this unique feature of multifocal lenses, patients will be able to
reduce dependence on spectacles during reading to a great extend after a cataract
operation. However, Multifocal lenses’ performances are compromised in patients who have

Multifocal Toric IOLs
Multifocal Toric lenses represent the last word in refractive IOLs and are exclusively
made by Rayner®. They offer the possibility of correcting distance refractive errors,
that include myopia, hyperopia and astigmatism, and near refractive errors. These
precision-engineered implants can provide excellent far, intermediate and near vision,
freeing patient from the need to wear any spectacles after a cataract operation.

This is a major advance as many patients who had astigmatism were previously unable to
benefit from multifocal lens implantation because astigmatism will compromised the
quality of vision that can be achieved in multifocal lenses.
