Increase visual field.
Not having a lens inside your eye - ACCURATE ANSWERS✔✔
Aphakia.
Which of the following can aphakia cause, myopia or hypermetropia? -
ACCURATE ANSWERS✔✔ Hypermetropia
Causes of aphakia - ACCURATE ANSWERS✔✔ *Congenital absence
of lens
*Surgical Aphakia
*Absorption of lens matter
*Traumatic extrusion (push or forced out)
*Posterior dislocation- in vitreous, causes optical aphakia
The cornea thins and bulges outward into a cone shape - ACCURATE
ANSWERS✔✔ Keratoconus
,Symptoms of Keratoconus - ACCURATE ANSWERS✔✔ *distorted,
blurred, double vision
*inability to see dim light
*sensitivity to light
Signs of keratoconus - ACCURATE ANSWERS✔✔ CORNEAL
THINNING AT THE APEX
CHANGES OF ASTIGMATISM
DECREASING VISION IN ONE EYE
Cause of keratoconus - ACCURATE ANSWERS✔✔ Cause is unknown,
but it is believed to be present at birth or the loss of collagen in the
cornea
How can be keratoconus be treated? - ACCURATE ANSWERS✔✔
*Surgical treatment
*Vision correction
*specialty contact
*Corneal cross link
Slows down and stop the progression of keratoconus but doesn't improve
vision - ACCURATE ANSWERS✔✔ Cornea Cross Linking
, A conical shaped cornea can best be fit with contact lenses through the
use of:
A.trial lenses
B. Keratometer readings
C. Eye impressions
D. Topogometer readings - ACCURATE ANSWERS✔✔ A. Trial lenses
Prism ballast lenses can be useful for: - ACCURATE ANSWERS✔✔
For cylindrical lenses and some bifocals
Helping to reduce lens rotation

ANSWERS✔✔ Back surface toric, Bitoric, and Spherical lenses
Base down prism from 0.75-1.5 diopters weighs the lens down and
keeps it stable so it doesn't rotate - ACCURATE ANSWERS✔✔ Prism
ballast
Bitoric lenses are prescribed:
A. Only when there is a small amount of corneal
B. Astigmatism and no residual when there 1s no corneal
