Advanced Laser Scanning Enables High-Precision Vision Corrections
https://www.photonics.com/Articles/Advanced_Laser_Scanning_Enables_High-Precision/a68283
Scan heads with innovative controls are already used in many industrial laser-based applications that require the highest precision and throughput. Now the benefits of scanning with zero tracking error are being positioned for ophthalmic applications related to vision correction, in which scan pattern fidelity is critical for a good patient care outcome. This smart control technology enables new and different strategies for diagnosis and treatment compared to the limitations of previous controls, which are affected by tracking error, especially when processing circles, spirals, and freeform structures. These advancements will allow completely new ophthalmic treatments, as well as successful and reproducible refractive surgeries. By using...
