Post-op follow-up was done by monitoring autorefraction
and visual acuity on days 1, 7, 30 and 90.

The importance of doing retinoscopy in a child rather than relying on autorefraction
cannot be over emphasised as looking at the quality of the reflex is very informative.
was performed on auto refractometer (Topcon KR 8900) on all subjects with VA below 20/30 in one or both eyes.
Accommodative Lag by Autorefraction
and Two Dynamic Retinoscopy Methods.
The OPD Scan II (Nidek, Japan) is a device that gives information about corneal topography, wavefront, autorefraction
, keratometry, and pupillometry, all in one instrument.
Evaluation included a dilated ophthalmoscopic exam to detect DR, early and advanced AMD, and optic nerve cupping due to glaucoma; and autorefraction
to detect URE at published sensitivities and specificities (Moss et al.
20) Given the controlled nature of the study, these preliminary results warrant additional research but seem to support autorefraction
as a possible screening mechanism that nurses and laypeople can use to identify children in a preschool setting.
For the 1999-2000, 2001-2002, and 2003-2004 surveys, participants also were asked questions regarding vision function, and the physical examination included a vision examination in which visual acuity was measured before and after an objective autorefraction
test (optical correction measured by all autorefractor).
The RK-F2 Full Auto Ref-Keratometer,Canon's newest Eyecare instrument, features a compact design - weighing 11 pounds less than its predecessor, and simplifies the standard autorefraction
and keratometry measurement procedure to just one step.

Most of us keep a watching brief and try to ensure that we are compliant with the spirit and letter of the contract, despite the fact that a one-shot sight test is just about the worst way to deliver primary eye care, short of autorefraction
