Example E (Myopic)
For a 63 year-old myopic patient with a distance refraction of -3.00 +2.00 X 75, refer to
.
Use a +2.00 cylinder lens and rotate the axis to 75 in the trial lens holder. Follow the -3.00 sphere
column to the 60 & Over row. The column entry indicates that the patient does not require a
spherical correction. Use only the cylinder trial lens correction.
Example F (Myopic)
For a 25 year-old myopic patient with a distance refraction of -4.00, use
Distance Rx is Over -3.00 column to the Under 30 row where you are instructed to add +3.25 to the
distance R
x
. The correct trial lens is -0.75.
Remember, you only need to use a trial lens when testing the central part of the patient’s visual
field. The trial lens must be removed for the peripheral portion of any Full Field test. A trial lens is
not used for either Superior Field screening test or any Peripheral threshold or screening test.
Note: If your patient is aphakic or needs a high refractive power such as +8.00 D, contact lenses
may provide the best visual field testing conditions.
No Trial Lenses Required for Esterman Monocular/Binocular Tests
This test is used to assess the level of a patient’s functional visual disability. The Esterman tests are
designed to be done using a patient’s everyday correction. If the patient does not require glasses to
function normally, perform the test without correction. If the patient does wear glasses to function
normally, perform the monocular or binocular test using the patient’s glasses. Do not use trial
lenses. You still must use the eye patch when testing with the Monocular version of the Esterman
test. Comprehensive testing instructions are provided in the section entitled
