Light split between Far, Intermediate, Near and light Loss. Light loss is light focused outside the vision range between Far and Near Apodization increases shift in percentage of light from Near to Far with pupil increase Central refractive zone and unique apodization design of diffractive zone results in small percent of light loss, below 4.2%. This reduces negative impact on contrast and halos by OptiVis
Follow-up 3 months,6 months Follow-up evaluations include Uncorrected (UCVA) Best corrected distance VA (BCDVA) Intermediate visual acuity Near visual acuity
Bilateral cataracts for which phacoemulsification and posterior IOL implantation has been planned for both eyes Strong desire to achieve spectacle independence Willingness to accept potential optical side effects and longer optical adaptation period after surgery Naturally dilated pupil size (in dim light) > 4.0 mm for both eyes Preoperative corneal astigmatism of 1.0 D or less Systemic or ocular disease, that may affect vision Diagnosed degenerative visual disorders History of ocular trauma or prior ocular surgery Amblyopia or strabismus Corneal abnormalities such as stromal, epithelial or endothelial dystrophies Intraocular inflammation or recurrent ocular inflammatory condition Pupil abnormalities Capsule or zonule abnormalities that may affect postoperative IOL centration or tilt
The FVA is a precision vision testing device that can be used for clinical testing or used for vision testing for research and clinical trials The FVA s precision illumination is continually controlled by a microprocessor for accuracy and repeatability of tests Capable of testing the following: Visual Acuity monocular and binocular at near, distant, and intermediate Contrast Sensitivity testing with F.A.C.T. (Functional Acuity Contrast Test) can be performed in both day and night resting conditions; both with and without glare and with a choice of two different glare levels (1 Lux and 28 Lux for night conditions)

The OptiVis diffractive-refractive multifocal IOL (Aaren Scientific) provides very good results for distance, intermediate and near vision. The six months results shows improvement in distance visual acuity and slight decrease in near visual acuity. After 6 months the perception of glares and halo significantly decreases. The satisfaction with the vision without the glasses at night improves.
