NOVEL REFRACTIVE EDOF INTRAOCULAR LENS FOR CONTINUOUS VISION

The lens of invention has been proven most suitable for the cataract patients. The invention provides extended depth of focus to get continuous vision from far to near distance up to closer distances. The third zone 60 degree segment design of invention is to provide balanced energy distribution at larger pupil diameter and the controlled spherical aberration at each zone provides minimalistic glares and halos. Further the EDOF IOL balances the nominal power and provide pupil independence further optimizing energy distribution in each annular zone to maintain the good contrast irrespective of the pupil size and light condition. Further, zonal modification in the IOL can be used as a controllable switch to change the depth of focus according to the requirement, viz. from distant to near vision or distant to intermediate vision.
