Special Features of Advanced Optic Lenses
It is an artificial lens that is implanted during cataract surgery. It is made up
of acrylic material and can be folded and inserted into the eye. Once inside the
eye, the IOL unfolds to its original size and shape.
- Aspheric Design: Most lenses have spherical surfaces which induce spherical
aberration. Aspherical lenses ensure aberration free image which gives better vision
and enhances contrast sensitivity, thus better night vision and under low light
- Square Edges: These lenses have square edges have square edges which prevent
the lens capsule from thickening, thus reducing the chances of after cataract or
- Anti-Glare Technology: Reflections and excessive light in the eye are reduced
which helps to reduce glare in the eye.
Monofocal IOL: Distant vision becomes clear but have to wear spectacles for
near vision. These are standard IOLs implanted in the eye after cataract surgery
for correction of distance vision only.
Monofocal Aspheric IOL: Improves contrast and image becomes more sharp and
bright. Also better quality of vision in dim light.
Toric IOL: It corrects cornical astigmatism so it improves quality of vision
in patient with high astigmatism (Cylinder power). These are monofocal IOLs implanted
in patients with pre-existing astigmatism and cataract. Provides spectacle free
vision even when patients had astigmatism before surgery. Most commonly used is
the Toric IOL.
Multifocal IOL: It improves distant intermediate & near vision. Specialized
IOLs. Patients are totally free of glasses for distance, intermediate and near vision
for all routine purposes.
Multifocal Toric IOL: Combine advantages of multifocal & Toric IOL. As the
name suggests, these Toric IOLs are implanted in patients with pre-existing astigmatism
and cataract. They provide spectacle-free vision at all ranges of work, distance,
near and intermediate.
