Summary

This video provides a comprehensive tutorial on operating a digital phoropter, covering its basic controls, refraction steps for sphere, cylinder, and axis, as well as advanced functions like PD adjustment, add power determination, binocular balancing, and prism application.

Key Points

  • The digital phoropter features standard controls for sphere, cylinder, axis, and add power, along with options for binocular, right, and left eye viewing. 
  • Power adjustments are made by turning the wheel, with left rotation adding plus power and right rotation adding minus power. 
  • Pupillary Distance (PD) can be easily adjusted by pressing the PD button, using the wheel to change the size, and confirming with the center button. 
  • VA charts are touchscreen-controlled, allowing selection of various letter sizes, and the display can be cleared or specific lines/letters isolated. 
  • After inputting auto-refraction sphere, the axis is refined using the JCC, following the phoropter's directional prompts, typically starting in five-degree steps. 
  • Cylinder power is then refined using the same JCC process, with the phoropter automatically maintaining the spherical equivalent. 
  • To determine add power, select an age, activate the 'add' function with both eyes open, and adjust until the patient achieves clear near vision. 
  • Binocular balance for younger patients involves splitting images and adjusting prism until clarity is achieved in both eyes. 
  • The phoropter allows for easy application of both horizontal and vertical prism to address conditions like diplopia. 
  • Upon completing the refraction, the final prescription data can be transferred to a paper chart or an electronic medical record system.
