PMMA Lens / BIOVISION®
All our PMMA Intraocular Lenses are manufactured of medical grade Polycast polymethylmethacrylate (PMMA).Our Single piece IOLs are designed by CAD technology & manufactured on CNC Lathe and CNC milling Machines and checked under Laser Interferometer for better optical quality. Dioptric powers are available within the ranges indicated at each model, in increments of 0.5 Dioptric steps.
All our Multipiece intraocular lenses are manufactured of Polycast polymethylmethacrylate (PMMA). The lens-haptics are made of blue, molecularly alined PMMA monofilament. All monofilaments haptics are tumble polished before assembly. Dioptric powers are available within the ranges indicated for each model, in 0.5 diopter steps.

Square Edge IOL
Nucleus 360° Square Edge IOL
Nucleus 360° Square Edge IOL
Posterior Capsular Opacification (PCO) in IOLs is a major concern among ophthalmologists at global level. Conventional round edge design allows migration of epithelial cells beneath the posterior surface of the lens resulting in PCO.
Nucleus 360° square edge intra ocular lenses are designed with square edge all around th posterior optic surface, including at haptic-optic junction. As shown in the figure (below), the 360° square edge acts as a complete barrier to epithelial cells and reduces incidence of PCO. The anterior surface of the Lens is round to avoid glare effect.

Nucleus 360° Square Edge IOLs are designed with capsular 'C' shape haptics and provide following advantages:
- Preserve natural anatomical shape of the capsular bag.
- Ensure better contact with the capsular bag resulting in distribution of haptic force and better centration post operatively.
- Easy implantation and placement.
- Minimal stress on zonules.
- Easy dialing.
