NCLE Basic Certification Exam
Read All Instructions Carefully and Answer All the
Questions Correctly Good Luck: -
A warpend lens wil show ______ base curves on the
radioscope and a___ power on the lensometer -
=Answer>> Two base curves, spherical power on the
lensometer
A RGP is designed with a thin overall profile so it may
flex or bend while on the cornea and become warped.
The warping will not change the power as read by the
lensometer, but it will create two different base curves
found with the radioscope to verify the amount of lens
warp.
If the tech measures 7.85mm (43 diopters)
by 7.76mm (43.50) diopters The lens is warped
by 0.50 diopters

A poorly finished transitional zone between the optic
zone and the lens edge can be evaluated by a -
=Answer>> Profile Analyzer
1. Radioscope - designed to accurately measure the
ROC of the anterior and posterior surfaces of rigid CL.
2. Lensometer - measures the back vertex power of a
lens
3. Proflie Analyzer - Measures the peripheral curves or
blends.
4. Biomicroscope - Another name for a slit lamp
5. Colmascope - used to look for stress inside a lens
6. Keratometer - measures central curve of the cornea
7. Topographer - maps the corneal surface of the eye.
8. Slot Gauge - uses a V slot to measure contact lens in
diameters of 0.1mm increments
How to extend the range of the keratometer - =Answer>>
+1.25 D lens will increase the keratometer reading by
9D to 61D
-1.00D lens will decrease the reading by 6D to 30D.
When documenting these new extended K readings be
sure to convert accordingly by adding 9D or subtracting
6D in the documentation

When inspecting the bevel blend of a gas permeable
contact lens using the flourescent bulb method the
inspector should - =Answer>> Observe a J shaped or ski
pattern in a smooth curve.
----> if the curves of the reflected light on the lens
surface are smooth and flowing, the peripheral curves
are well blended they should represent the path of skis
on a ski slope called ski blend
When using a keratometer, the amount of corneal
astigmatism - =Answer>> is the difference between the
reading on the horizontal and vertical drums
When inspecting a gas permeable lens, a ________ may
be used to evaluate the transitional zone between the
optic zone and the lens edge - =Answer>> Profile Analyzer
When the question asks about the transitional zones
and blends. The profile analyzer is the best answer if it
is an option
A _______ is used to measure the posterior optical zone
diameter - =Answer>> Measuring magnifier
Measuring magnifier - measures the hard CL diameter,
optic zone and height of bifocal contact lenses
If all the mires are not in focus along the principal
meridians when verifying a gas perm on a radioscope,
the more than likely the lens is: - =Answer>> Warped
