Does the virtual refractor patient-simulator improve student competency when refracting in the consulting room?

Area of Science:

• Ophthalmic education
• Medical simulation
• Optometry training

Background:

• Patient simulators are underutilized in ophthalmic education.
• This study investigated the impact of the 'Virtual Refractor' simulator on optometry students' refraction skills.

Purpose of the Study:

• To evaluate the effectiveness of the Virtual Refractor patient simulator in improving students' ability to determine spectacle lens power.
• To assess the impact on student accuracy, speed, knowledge, and confidence.

Main Methods:

• Twenty-four first-year optometry students were divided into a simulator-intervention group and a control group.
• Both groups received refraction training; the intervention group also used the Virtual Refractor.
• Student accuracy and speed in determining spectacle lens power were measured using real patients.

Main Results:

• Simulator users were significantly more accurate (0.22 ± 0.22 DS vs. 0.60 ± 0.67 DS) and 13% quicker (4.7 minutes).
• Students using the simulator reported higher knowledge and confidence levels.
• Simulator users practiced an average of 5.7 hours at home.

Conclusions:

• The Virtual Refractor effectively bridges theoretical knowledge and clinical application in optometry.
• High-fidelity simulation enhances learning and can be used flexibly without increasing student time burden.
• This simulator improves accuracy and speed, potentially reducing clinical supervision needs.
