Summary
The QuickSee handheld aberrometer shows good agreement with subjective refraction for diagnosing refractive errors in children. This device is a useful tool for autorefraction, improving visual acuity in pediatric patients.
Area of Science:
- Ophthalmology
- Optometry
- Pediatric Eye Care
Background:
- Refractive errors are common in school-aged children.
- Accurate diagnosis is crucial for timely intervention and optimal visual development.
- Existing autorefraction methods may have limitations in pediatric populations.
Purpose of the Study:
- To evaluate the diagnostic performance of the open-view binocular handheld aberrometer (QuickSee) for refractive errors in children.
- To compare the QuickSee device's accuracy against standard autorefraction and subjective refraction.
- To assess the visual acuity outcomes achieved with the QuickSee device.
Main Methods:
- 123 school-age children with moderate refractive error participated.
- Measurements were taken using autorefraction (AR), subjective refraction (SR), and QuickSee (QS) with and without cycloplegia.
- Agreement in spherical equivalent refraction and visual acuity (VA) were primary outcome measures.
Main Results:
- QuickSee (QS) agreed within 0.5 D of subjective refraction (SR) in 70-71% of cases.
- Visual acuity achieved with QS was equal to or better than SR in 74-77% of children.
- QS demonstrated comparable or superior agreement to desktop autorefractor in some comparisons.
Conclusions:
- The QuickSee handheld aberrometer demonstrates high agreement with subjective refraction.
- The device effectively improves visual acuity in pediatric patients.
- QuickSee is a valuable tool for autorefraction in school-aged children.
