a right, prosthetic eye has a palpebral aperture that is larger than the left, seeing eye. the horizontal dimension of the aperture is definitely not larger than the seeing eye. what would be your first trial lens option for the prosthetic eye?

a. a plano, plus cyl, axis 180

b. a plano, plus cyl, axis 90

c. a plano, minus cyl, axis 180

d. a plano, minus cyl, axis 90

e. a plus sphere lens

use a minus sphere lens

problem: the eye looks large

desired cosmetic effect: make the eye look smaller

what is the lens solution?

use a minus cyl, axis 180

problem: eye open wider than seeing eye (fissure looks too large vertically)

desired cosmetic effect: close the eye somewhat

what is the lens solution?

use a plus cyl, axis 90

problem: eye looks too small horizontally

desired cosmetic effect: widen the horizontal appearance of the eye

what is the lens solution?

use a minus cyl, axis 90

problem: eye looks too wide horizontally

desired cosmetic effect: narrow the horizontal appearance of the eye

what is the lens solution?

use BU prism

problem: eye looks too high

desired cosmetic effect: lower the apparent height of the eye

what is the lens solution?

rotate plus cyl axis against the direction of desired tilt or rotate minus cyl axis w/ the direction of desired tilt

problem: eyelid is slanted

desired cosmetic effect: cause the rotated appearance of the lid to change in tilt & match the horizontal look of the seeing eye
