Answer 27

Lenticular

Question 28

With accommodation relaxed, both principle meridian focus in front of the retina.

Answer 28

Compound Myopic Astigmatism

Question 29

With accommodation relaxed, one meridian would focus on the retina and the other would focus in front of the retina.

Answer 29

Simple Myopic Astigmatism

Question 30

Withe accommodation relaxed, one meridian tends to focus behind the retina, while the other focuses in front of the retina.

Answer 30

Mixed Astigmatism
