Intraocular Lens (IOL) Processing by Optimized Femtosecond Lasers
Lumos’s innovative GHz burst pulsed femtosecond lasers and femtosecond pulsed lasers are tailored to address these challenges head-on. The ultra-short pulse durations coupled with the optimized GHz burst parameters allow for a controlled energy delivery to the material, significantly limiting thermal stress. This control is crucial for preventing micro-defects and melting, ensuring the integrity and precision of the intraocular lenses.
By delivering lower energy pulses at a high repetition rate, GHz Burst lasers not only reduce the risk of material damage but also enhance the material processing efficiency. This feature is instrumental in meeting the industrial need for high-speed production while ensuring repeatability, a critical factor in intraocular lens processing.
The effort for developing this technology is backed by substantial funding and support from both the European Union through the PULSATE program and The Scientific and Technological Research Council of Turkey (TÜBİTAK)1. These comprehensive projects underpin Lumos’s commitment to elevating the standard of intraocular lens processing, bridging the gap between industrial production demands and the requirement for precision.
Beyond merely cutting, femtosecond lasers play a significant role in the overall processing of intraocular lenses, paving the way for personalized lens manufacturing. This advancement not only facilitates the creation of personalized lenses but also eliminates the need for different molds for each lens, significantly streamlining the production process.
