movement. Decentration and excessive lid sensation accompanied

by limited movement often indicates the lens is too at for the given

eye.

If the criteria for a well-tted lens cannot be achieved, do not dispense.

C. Final Lens Power Determination

After the characteristics of a well-tted lens have been satised, conduct

a spherical over-refraction to determine the proper lens power to be

dispensed.

Example:

Trial lens: -4.50D

Over-refraction: -0.25D

Final Lens Power: -4.75D

Use a fresh, new pair of lenses for each trial tting. Do not attempt to disinfect

and re-use trial lenses.

Toric lens is a double thin zone design. The back surface tri-curve

toric design is available in one base curve and ts a wide variety of eyes,

reducing tting time and inventory requirements. The FOCUS

Toric lens design has a constant

thickness difference between the vertical, thin zones and a horizontal thicker

zone, resulting in consistent and excellent stabilization over the power range.

Toric lenses feature scribe lines on the front lens

surface to enable assessment of the lens orientation. These lines are at

3 and 9 o’clock positions approximately 1.0 mm in from the lens edge.

The vertical line of the "K" on the "OK" inversion mark coincides with the

90 degree meridian of the lens and thus might also be used for the

assessment of the lens orientation. The lens orientation ndings are then

used for calculation of axis compensations.

Toric lenses are similar
