Do Femtosecond Lasers Improve Accuracy of Cataract Surgery?
March 6, 2012
According to a study presented at the World Ophthalmology Congress 2012 in February, using a femtosecond laser for capsulotomy has better accuracy and precision than standard continuous curvilinear circular capsulorhexis techniques.
Dr. Jose L. Guell, MD, the leader of the study, further suggested that the high degree of control available with femtosecond lasers may enable physicians to improve the final lens position.
Meanwhile, late last month, OptiMedica Corp. announced the launch of its Catalys Precision Laser System in the United States, with the first patient cases performed by Drs. Mike and Paul Mann at the Mann Eye Institute in Houston. The system was cleared for market by the U.S. Food and Drug Administration in late December 2011.
Drs. Mann are now using Catalys to perform laser capsulotomy and lens fragmentation during cataract surgery. Findings published in the peer-reviewed publications Journal of Cataract & Refractive Surgery and Science Translational Medicine have demonstrated the system’s ability to deliver industry-leading improvement in precision and accuracy across these steps, with incision accuracy results measured in tens of microns. Laser lens fragmentation with Catalys has also been shown to greatly improve the ease and gentleness of lens disassembly, reducing cumulative dissipated energy (CDE) during ultrasound phacoemulsification by approximately 40 percent.
