W11 Objective and Subjective Refraction

Which clues indicate which refractive error px has?

Near vision blur with good distance vision suggests hyperopia

Distance vision blur with good near vision suggests myopia

Blur at all distances indicates significant astigmatism

What procedures would you do to ensure your px is not accommodating in retinoscopy?

Keep both eyes open, use duochrome, don’t block patients view, fog the eye

What procedures would you do to ensure your px is not accommodating when doing subjective refraction?

Use most positive/minimum minus lens for max VA

Performance +1.00 check test

If testing on a hyperope, do not remove trial frame lens until new ones in place

How do you set up static retinoscopy?

Tell px to focus on green target, turn off room lights, push ret collar down, fog eye with +1.00D lens to obtain against movement

What do you after setting up static ret?

…

What do you do after static ret?

Refine the sphere, then refine cylinder axis with jcc
