Our handheld autorefractor / keratometer’s combination of the open view design, wavefront aberrometry, and innovative measurement algorithms produces clinically accurate autorefraction and keratometry results, comparable to the best desktop autorefractors but in a compact, handheld format.

The patented PlenOptika Wavefront Refraction Engine™  precisely determines low-order refractive errors, demonstrating excellent agreement with subjective refraction.

QuickSee Free Pro’s technology has been clinically-evaluated in five IRB-based studies and documented in many peer-reviewed publications and conference abstracts. QuickSee Free has FDA Class I 510(k) exempt medical device registration.
