AI Technical Summary

Technical Problem

Existing ophthalmic laser treatments for conditions like glaucoma and retinal diseases face limitations in spatial modulation, energy delivery, and tissue preservation, leading to broad tissue disruption, undertreatment, and collateral damage.

Method used

The system employs high-speed scanning of micro-spots to create 'virtual treatment zones' with fractional, geometric, and multi-layered energy distributions, allowing for 'Soft SLT', 'Ring SLT', and 'Multi SLT' modalities that preserve tissue and enhance treatment efficacy.

Benefits of technology

This approach reduces tissue disruption, enables precise energy delivery, and improves treatment outcomes for glaucoma and retinal conditions by preserving healthy tissue bridges and inducing biomechanical tension, thereby enhancing aqueous humor outflow and reducing retinal damage.

Abstract

An ophthalmic laser platform is provided herein that can perform "intra-spot micro-patterning" on anterior and posterior segments by scanning (sub)nanosecond micro-spots within a "virtual macro-spot." This architecture enables three modalities: "soft mode" utilizes dynamic spatial fractionation to create untreated tissue bridges; "ring mode" applies annular patterns to induce biomechanical tension or centripetal cell migration; and "multi mode" employs multi-pass scanning for sub-threshold fluence accumulation. The system is capable of delivering optimized, tissue-preserving therapies for glaucoma through selective laser trabeculoplasty (SLT) and for retinal conditions, including macular degeneration).
