Targeted region
The refractive structure is written into a defined micro-scale region within an existing intraocular lens.
Technology
A femtosecond laser based platform for precise refractive modification of intraocular lenses
Perfect Lens develops femtosecond laser based technology that enables precise refractive modification of of hydrophobic and hydrophilic acrylic materials without surface alteration.
At the core of the platform is Refractive Index Shaping (RIS), a controlled, volumetric process that creates localized changes in hydrophilicity within an acrylic intraocular lens. By directing femtosecond laser pulses into a defined region of the lens, RIS induces predictable refractive changes while preserving the lens' structural and mechanical integrity.
Refractive outcomes are achieved without cutting, ablation, or surface modification, allowing optical properties to be tailored while maintaining the original lens geometry. This approach bridges clinical flexibility and manufacturing control, opening new pathways for customized optics and advanced intraocular lens designs.
The technology is designed as a process rather than a single application. RIS supports multiple use cases, including post-implant refractive adjustment and customized lens shaping in manufacturing environments, enabling high precision, repeatability, and scalability. Post-implant (in vivo) applications are investigational and are being evaluated in research and clinical study settings.
How it works
Controlled scan
A guided femtosecond scan forms hydrophilic patterns that translate into predictable refractive profiles.
Optical outcome
The refractive change is created within the lens material, enabling correction while preserving the lens surface geometry.
The RIS Platform
Volumetric Refractive Control
RIS modifies optical properties within the lens material itself, enabling homogeneous and repeatable refractive changes independent of surface geometry.
Precision and Repeatability
Ultrafast laser pulses and controlled scan patterns allow refractive outcomes to be defined with high spatial accuracy and consistency.
Platform Versatility
The same core technology supports both in-vivo refractive adjustment and manufacturing-based customization workflows.
Non-Ablative Process
Optical changes are achieved without cutting, ablating, or removing material, preserving lens structure, weight, and mechanical properties.
Applications
Post-Implant Refractive Adjustment
Investigational workflows designed to enable controlled refractive modification of implanted intraocular lenses without surgical lens exchange.
