NIDEK 5100 Basics

Summary

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. 1:02
• —Power adjustments are made by turning the wheel, with left rotation adding plus power and right rotation adding minus power. 1:24
• —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. 2:11
• —VA charts are touchscreen-controlled, allowing selection of various letter sizes, and the display can be cleared or specific lines/letters isolated. 2:53
• —After inputting auto-refraction sphere, the axis is refined using the JCC, following the phoropter's directional prompts, typically starting in five-degree steps. 4:10
• —Cylinder power is then refined using the same JCC process, with the phoropter automatically maintaining the spherical equivalent. 6:21
• —To determine add power, select an age, activate the 'add' function with both eyes open, and adjust until the patient achieves clear near vision. 8:07
• —Binocular balance for younger patients involves splitting images and adjusting prism until clarity is achieved in both eyes. 8:34
• —The phoropter allows for easy application of both horizontal and vertical prism to address conditions like diplopia. 10:01
• —Upon completing the refraction, the final prescription data can be transferred to a paper chart or an electronic medical record system. 10:51
