2 After determining patient s spectacle refraction at distance and at near (16 in.):1) Determine dominant eye. (Consider fogging with a + lens.) 2) Place the D lens on the dominant eye and the N lens on the non-dominant eye.* Note: Vertex Sphere if over ) Evaluate visual acuities under normal light conditions for distance and near vision, first binocularly then monocularly, if necessary.

Do not use a ) balanced Progressive technology allows for independent adjustment of either distance sphere power or aDD power of a maximum of +/- this means the aDD can be changed up to +/- without affecting the distance sphere power and vice versa on the same ) Visual acuity of 20/25 or 20/30 is acceptable after initial fit even if the lens rotates +/-15 degrees.
4 If patient is seeing 20/25 or 20/30, let the patient leave and return a week later to see if the lens has stabilized. if everything is stable, let the patient leave with the lenses. if the lens is not stable, make any necessary adjustments to the axis first, then ) i f you are refitting a patient from monovision, have the patient remove the lenses worn for monovision at least 48 to 72 hours before being fit in proclear multifocal toric to allow the brain to adjust from being fit in monovision.

5 A common misconception is that if there is a problem with distance, it is in the D lens. Since both lenses incorporate distance, intermediate, and near vision, often the problem with the distance vision will be in the N parametersfor multifocal consultation, call cVspo 866-316-9358sphere powermaterialadd powerwearingschedulewatercontentBase curVe(mm)diameter(mm)lens carelens powerhandlingtint+ to (in steps after +/- )omafilcon a59% or disinfection + to + ( steps)D lensN lensfiPS 5 to 180 (in 5 steps) to ( steps)Daily Wearlightbluemultifocal toric fitting tips eXample #1 eXample #2 spectacle rX oD: x 180 add + D lens oD: x 180 add + D lens oS: x 180 add + N lens oS: x 160 add + N lens final contact lens rX oD.
