NCLE PRACTICE TEST QUESTIONS |
GUARANTEED ACCURATE
ANSWERS
Steep Fluorescein Pattern - ACCURATE ANSWERS✔✔ Bright green
pooling center, very faint green pooling on diameter of lens
Flat Fluorescein Pattern - ACCURATE ANSWERS✔✔ Bright green
pooling on diameter of lens, very faint green in center
Against-the-rule Astigmatism Pattern - ACCURATE ANSWERS✔✔
Bright green pooling horizontally, faint green pooling vertically
With-the-rule Astigmatism Pattern - ACCURATE ANSWERS✔✔
Bright green pooling vertically, faint green pooling horizontally
Prism Ballast - ACCURATE ANSWERS✔✔ Common technique to
stabilize lens from rotating. Added thickness will position lens inferiorly
(bottom of cornea)
Truncation - ACCURATE ANSWERS✔✔ Cutting off .50mm to
1.50mm of bottom edge of lens to provide stability. Reduces diameter,
making a looser fit.
,Double Slab-off - ACCURATE ANSWERS✔✔ Lens is thicker centrally
and thinner at top and bottom of lens. Provides comfort to wearer, but
may cause some stability issues.
Aspheric Lens Design - ACCURATE ANSWERS✔✔
Hyperflange - ACCURATE ANSWERS✔✔ Used to correct high riding
minus lenses.
Myoflange - ACCURATE ANSWERS✔✔ Used to correct low riding
plus lenses.
Monovision - ACCURATE ANSWERS✔✔ Corrects presbyopia in
contact wearers. One eye uses distance (dominant) and the other eye
uses reading (resessive)
Segment Bifocal - ACCURATE ANSWERS✔✔ Same concept as
spectacle bifocal. Must be prism ballast. Often crescent shaped.
Toric Lenses - ACCURATE ANSWERS✔✔ Anterior (front surface),
back spherical surface or posterior (back surface), toric back curve
Front Toric Lens - ACCURATE ANSWERS✔✔ Corrects a low to
moderate amount of corneal astigmatism
, Back Toric Lens - ACCURATE ANSWERS✔✔ Corrects a mid to high
amount of corneal astigmatism
Bitoric Lens - ACCURATE ANSWERS✔✔ Corrects 1.50D of corneal
astigmatism and high residual astigmatism
Aphakic - ACCURATE ANSWERS✔✔ Condition of no crystalline lens
Psuedophakic - ACCURATE ANSWERS✔✔ Implant, intraocular lens
Corneal Edema - ACCURATE ANSWERS✔✔ Always causes a poor
fitting lens
Spectacle Blur - ACCURATE ANSWERS✔✔ Temporary blurred vision
upon switching from contact lenses to eyeglasses
Crystalline Lens - ACCURATE ANSWERS✔✔ The main focusing
mechanism of the eye
The Main Supply of Oxygen to the cornea is provided by - ACCURATE
ANSWERS✔✔ Tear Film
