Objective:

To investigate the transmission of red and violet wavelengths through ocular structures and their implications for light-based therapies in myopia control.

Key Findings:
  • Red light demonstrated greater transmission than violet light across anterior and posterior ocular structures.
  • Corneal, lenticular, and retinal transmission were significantly lower for violet LEDs compared to red sources.
  • The lens was identified as a key barrier to shorter wavelengths, with violet light strongly attenuated before reaching the retina.
  • Less than 1% of incident light reached the sclera across all light sources examined.
  • Red LEDs achieved transmission levels comparable to red lasers, suggesting a safer alternative.
Interpretation:

Limitations:
  • The study used porcine eyes, which may not fully replicate human ocular responses.
  • The findings may not account for variations in individual patient anatomy and light exposure conditions.
Conclusion:
