CHANGES OF ASTIGMATISM
DECREASING VISION IN ONE EYE
cause of keratoconus - ANSWER-✅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? - ANSWER-✅*Surgical treatment

D. When there is at least 2.00D of corneal astigmatism accompanied by a significant
amount of residual astigmatism - ANSWER-✅D. When there is at least 2.00D of
corneal astigmatism accompanied by a significant amount of residual astigmatism
