Although there are several systems currently available that can perform laser cataract surgery, Vision Eye Institute has chosen LenSx® femtosecond laser cataract surgery technology by Alcon. It was the first femtosecond laser cataract surgery platform to be approved by the FDA and TGA, and the first system released in the US and Australia.
The LenSx® femtosecond laser technology performs three crucial stages of the cataract procedure – corneal incisions, capsulorhexis and phacoemulsification in a single step. This minimises risk and optimises post-operative visual outcomes. To date, the LenSx® platform is the only system which has FDA approval for all three of these stages.
The LenSx® femtosecond laser is computer controlled, creating precise incisions in the eye and an optimal sized opening in the front of the lens capsule. It then divides the cataract, all controlled by a high-precision, image-guided femtosecond laser. This prepares the eye successfully for the subsequent cataract surgery steps and IOL insertion.
Femtosecond lasers use ultra short pulses of near-infrared light to disrupt tissue. The high degree of precision of femtosecond laser technology has been proven over the last 10 years, having been used successfully during laser eye surgery (LASIK). Guided by optical coherence tomography (OCT), the LenSx® platform creates 3D imaging of the eye.
With this information, the surgeon can plan the procedure. Once final checks are made, the laser is started, automating the first three steps of cataract surgery. The actual laser will be used for less than 60 seconds.
