After cataract removal, the natural lens is replaced with an intraocular lens (IOL). These lenses are clear, tiny implants that help focus light properly onto the retina, restoring vision.
◑︎ Monofocal Lenses — Provide clear vision at one distance—usually for distance vision. Reading glasses may still be required.
◑︎ Multifocal Lenses — Allow focus at multiple distances, reducing the need for glasses. They use concentric zones to deliver near, intermediate, and distance clarity.
◑︎ Toric Lenses — Correct astigmatism by compensating for irregular corneal curvature, improving sharpness.
◑︎ Accommodative Lenses — These mimic natural lens movement, adjusting between distances by shifting focus dynamically.
◑︎ Extended Depth-of-Focus (EDOF) Lenses — Provide continuous vision from distance to intermediate range, reducing glares and halos common in multifocal lenses.
Factors determining the best lens include:
◑︎ Lifestyle preferences (e.g., reading, driving)
◑︎ Occupation and visual needs
◑︎ Eye anatomy and preexisting conditions (such as astigmatism)
◑︎ Budget and cost considerations
Our expert team at Chopra Nethralaya will perform measurements (biometry) to determine lens power and discuss the most suitable lens type.
Modern lenses come with aspheric design for sharper vision and UV filters to protect against light damage. Premium IOLs, while costlier, can significantly enhance post-surgery vision quality and reduce dependence on spectacles.
