Brief
Course Description

Modification
& Delivery

This
course covers the subjects of in-office contact lens modification of
rigid lenses, and delivery to the patient. Also included in this copurse
is some supplementary information on the use of the radiuscope, on DK
value and gas permeable lenses, and ANSI standards for rigid and soft
lenses.

The
in-office modifications which are possible with rigid lenses include:
reducing the overall lens diameter, flattening the base curve, blending
transition zones, removing scratches, adding minus power, adding plus
power and dotting the lens for identification. The use of the radiuscope
will be described and illustrated as it is used to verify the radius
of curvature of a spherical surface. We continue with a discussion of
the uses of contact lens solutions for rigid and soft lenses. These
include wetting, cleaning, and soaking solutions for rigid lenses, and
cleaning, disinfecting, rinsing, and re-wetting solutions for soft lenses.
This is followed by a discussion of patient instruction techniques for
lens insertion and removal as well as recommended “breaking-in” wearing
schedules.

An
abbreviated chart of ANSI standards is also presented. This chart consists
of the most referenced standards for rigid and soft lenses— those which
you may be called upon to know. We conclude with a glossary of important
terms which were used throughout this course, as well as some which
you may be seeing for the first time
