The enVista® IOL and the Victus® femtosecond laser are among the innovations that enable consistent vision outcomes.
In the realm of refractive cataract surgery, #cataractsurgery consistency is king. The more variables we can eliminate to standardize each step of the procedure, the better able we are to refine our results and deliver the spectacle-free vision patients desire. In my practice, I’ve been using several new technologies that help me ensure accuracy and consistency.
How the Latest Technologies Can Help
Our practice was an early adopter of femto technology, because we believed the femtosecond laser could be used to automate the cataract surgery maneuvers that are most vulnerable to human error, thereby taking our results to the next level. In my practice, we use two different platforms. They’ve both been outstanding, and I’ve found the Victus Femtosecond Laser (Bausch + Lomb) to be particularly effective for creating the ideal and complete anterior capsulotomy. Compared to executing these steps by hand, I’m much more likely to achieve a properly sized and centered rhexis that will serve to keep the IOL in the optimum position. I’m also much less likely to have an incomplete rhexis that could compromise the posterior capsule during phacoemulsification.
The Victus platform also has FDA clearance for the creation of arcuate incisions, which helps me improve correc¬tion of preexisting corneal astigma¬tism for refractive cataract surgery patients. This is an important goal because even small amounts of residual astigma¬tism can compro¬mise postoperative uncorrected visual acuity. While manual astigmatism-correcting incisions, such as limbal relaxing incisions (LRIs) can be effective, the laser can place the wounds in the specified optical zone and axis, and can achieve precise depth across the entire incision more accurately. more accurately.
I use the femtosecond laser as part of the refractive cataract surgery package I offer to eliminate or reduce patient dependence on eyeglasses or contact lenses. Approximately 50% of the patients in our practice choose an advanced procedure that involves LRIs and/or a toric or presbyopia-correcting IOL. These procedures include additional preoperative steps, such as analysis of corneal astigmatism, wavefront measurements and double and triple-checking of biometry with more than one device.
