as the trial lenses. Record rotation compensation as part of the nal Rx.

D. Initial Visual Evaluation

The visual result is evaluated by rst performing a spherical over-

refraction and then measuring visual acuity. If visual acuity is

acceptable, the determination of lens power required after the

over-refraction will be uncomplicated. In this case, the axis in

accepted notation will be the difference between the absolute value

determined and 180 degrees.

Example:

Diagnostic Lens: -2.00 -0.75 x 180

Over-refraction: -0.50 sphere

Final Power to Order: -2.50 -0.75 x ...*

*Determination of nal cylinder axis to order will be made

after compensation for lens orientation.

If the spherical over-refraction does not yield acceptable vision

proceed to perform a spherocylindrical over-refraction. For

the resultant lens power to order from this over-refraction call

The FOCUS

®

DAILIES

®

Progressives (nellcon A) lens is a progressive

aspheric simultaneous vision soft contact lens. The lens design

incorporates a constant near power prole into each lens across the

full range of distance powers. This simplies the tting procedure by

eliminating add powers as a separate variable. For each lens, the near

and intermediate powers are concentrated primarily in the central portion

of the optical zone while the surrounding portion is weighted towards

distance. The continuous changes in power across the surface of the

lens allow patients requiring a reading addition of up to +3.00D to see

clearly at far, intermediate and near distances.

1. PATIENT SELECTION

The eye care professional should weigh several factors when considering

patient selection for a FOCUS

contact lens tting. When tting a lens intended to correct for presbyopia,

it is especially important to evaluate the particular visual needs, objectives,

lifestyle and expectations of the individual patient. Prospective candidates

may include current contact lens wearers, former wearers, and persons with

no previous wear history. For former wearers it is important to determine the

cause for discontinuation. Good success has been achieved with FOCUS

There are two general categories of candidates based on anticipated usage:

those who seek to wear their lenses as their principal means of vision

correction, and those who wish to integrate the use of their contact lenses
