Order of techniques to be performed:
- Interview the patient and determine a complete profile of the patient's
primary complaint, any secondary complaints or concerns, the complete history of
the patient (both ocular and systemic), the family history of the patient, and
their occupational, avocational, and environmental circumstances. Record your
findings.
- Measure the monocular visual acuity of the patient; unaided first, then
aided, at farpoint and nearpoint, in both eyes. State and record your findings
(Snellen and metric acuities allowed).
- Measure the farpoint pupillary distance and then perform static retinoscopy
on each eye. State and record your findings.
- Using the result from your
static retinoscopy as a starting point, perform a
subjective refraction on both eyes including a
binocular balance of accommodation using dissociated
prisms and fogging technique. Use a phoropter for this
procedure. State and record your findings.
- Using your refraction result, measure and
determine the tentative add power required using one
of the three methods below (please indicate the method
used):
-
Sheard's method
- Nearpoint retinoscopy
- Monocular crossed cylinder technique
- Determine, state and record the optimum nearpoint addition for each eye at
40 cms. with a balanced depth of field.
Equipment provided in room:
- Examining chair, stool and equipment stand
- Record paper and pen
- Projected acuity chart (may be automated)
- Phoropter with nearpoint rod and card
Equipment provided by candidate:
- Occluder
- PD ruler
- Retinoscope
- Nearpoint acuity card
