INTRA OCULAR LENSES
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 conditions.
- 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 Charri.
- 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.
