Femto-Transprk And Robo-Transprk: Extending The Future Of Transepithelial Laser Vision Correction

To introduce and evaluate two forward-looking concepts in transepithelial refractive surgery: Femto-TransPRK and Robo-TransPRK, aiming to enhance precision, biomechanical stability, and procedural automation.

N/A

This conceptual and technical analysis is based on established principles of transepithelial surface ablation, femtosecond laser photodisruption, and automated surgical workflows. Femto-TransPRK is designed as a surface lentoid created through intact epithelium using near-infrared femtosecond laser energy without flap or cap formation. Robo-TransPRK proposes an integrated automation framework incorporating robotic positioning, AI-assisted workflow management, and multimodal diagnostic data integration.

Femto-TransPRK enables single-plane refractive lentoid creation with substantially reduced energy deposition compared with excimer-based ablation and conventional lenticule extraction. The virtual-cap design may reduce epithelial trauma, inflammatory response, and postoperative haze while preserving corneal biomechanics. Robo-TransPRK introduces standardized automation of patient alignment, centration, data transfer, and treatment initiation, potentially improving reproducibility, efficiency, and scalability in refractive surgery centers.

Femto-TransPRK represents a potential evolution toward low-energy, all-femtosecond transepithelial surface ablation, combining advantages of surface ablation and lenticule extraction. Robo-TransPRK extends this trajectory toward fully integrated and standardized refractive surgery workflows. Together, these concepts provide a framework for future innovation in laser vision correction and invite further experimental and clinical validation.
