Desktop power in a handheld autorefractor
Measurements in 10 seconds
Modern, intuitive operator and patient experience
Our handheld autorefractor’s combination of the open view design, wavefront aberrometry, and innovative measurement algorithms produces clinically accurate autorefraction measurements, in a durable handheld format suitable for use in clinics and in the field.
The patented PlenOptika Wavefront Refraction Engine™ precisely determines low-order refractive errors, making QuickSee Free as accurate as the high-end clinical desktop autorefractors and demonstrating excellent agreement with subjective refraction.
QuickSee Free’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.
QuickSee Free’s UI is clean, intuitive, and robust
