Brief Summary

The goal of this clinical trial is to evaluate whether a new 3D-printed eyeball movement simulator improves medical education compared to traditional teaching methods. The main questions it aims to answer are: Does using the 3D simulator help medical students better understand eye anatomy and muscle function compared to standard lectures and textbooks? How do students rate the usability and effectiveness of this new teaching tool? Researchers will compare two groups of medical students: One group will learn using the 3D simulator The other group will receive standard teaching methods Participants will:

1. 1.Complete a pre-test to assess their baseline knowledge
2. 2.Attend training sessions using either the 3D simulator or standard methods
3. 3.Take a post-test to measure learning improvement
4. 4.Provide feedback about their learning experience
5. 5.Take a post-intervention exam and satisfaction survey
6. 6.Participate in focus groups about their learning experience

Outcome Measures

Primary Outcomes (1)

• Knowledge Gain Score

  Difference in test scores between pre-intervention and post-intervention assessments on eye anatomy and movement kinematics, measured using a validated 50-point multiple-choice questionnaire

  Baseline (pre-intervention), Immediately after intervention (1 day post-training)

Secondary Outcomes (2)

• Skill Acquisition in Eye Movement Assessment

  "Baseline" or "Day 1"

• Student Satisfaction Scores

  Immediately post-intervention

Study Arms (2)

3D Eyeball Movement Simulator Group

EXPERIMENTAL

Arm 1 (Experimental Group): Participants in this arm will use an interactive 3D-printed simulator that physically replicates human eyeball movements and extraocular muscle function. This hands-on educational tool allows medical students to manipulate the model and observe biomechanical principles of eye movements in real-time.

Device: 3D Eyeball Movement Simulator Group

Conventional Teaching Methods Group

ACTIVE COMPARATOR

Participants in this arm will receive standard anatomy instruction through traditional methods including didactic lectures, 2D textbook illustrations, and static anatomical models - representing the current typical curriculum for ophthalmic anatomy education.

Other: Conventional Teaching Methods Group

Interventions

3D Eyeball Movement Simulator Group DEVICE

A physical, interactive 3D-printed educational model that replicates human eyeball movements and demonstrates the biomechanical action of extraocular muscles. The simulator allows hands-on manipulation to demonstrate all cardinal eye movements (adduction, abduction, elevation, depression, intorsion, and extorsion) through mechanical actuation of synthetic muscle analogues."

3D Eyeball Movement Simulator Group

Conventional Teaching Methods Group OTHER

Standard medical education methods for teaching eye anatomy and movements, including: (1) didactic classroom lectures with 2D illustrations, (2) static anatomical models of the orbit and eyeball, and (3) textbook-based learning materials. This represents the current conventional approach to teaching this content in medical curricula
