Area of Science:

  • Ophthalmology
  • Medical Education

Background:

  • Retinoscopy is a key objective method for assessing refractive status, particularly in challenging patients.
  • The traditional learning curve for retinoscopy is steep, causing student frustration.
  • The COVID-19 pandemic highlighted the need for effective simulation-based clinical education.

Purpose of the Study:

  • To evaluate the learning curve of retinoscopy using a novel training protocol.
  • To reduce student stress and shorten the learning time for retinoscopy.

Main Methods:

  • A study involving 100 trainees assessed at 8, 12, 16, and 20 hours of training.
  • Six common refractive defects were simulated to mimic clinical scenarios.
  • Non-parametric statistics and linear regression analyzed training time and performance rates.

Main Results:

  • Mean performance scores increased from 32.49% at 8 hours to 84.26% at 20 hours.
  • Performance at 12 hours was significantly higher than at 8 hours.
  • A strong positive correlation (R = 0.9773) was found between retinoscopy practice time and performance.

Conclusions:

  • Increased retinoscopy practice hours correlate positively with improved performance.
  • A protocol and performance standardization estimate a minimum of 13.4 hours for 60% proficiency.
  • A formula can now estimate the practice hours required to achieve specific retinoscopy performance levels.
