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.
