Multiburst mode on Stellaris phaco system advantageous for early postoperative outcomes

WASHINGTON — Patients who have undergone femtosecond laser-assisted nuclear fragmentation and capsulotomy with a phaco system on multiburst mode experienced positive early postoperative outcomes, according to a speaker here.
“Multiburst modality on a Stellaris vision enhancement phaco system (Bausch + Lomb) has shown a clear overall advantage when used in combination with femto pre-softening at the different grades of cataract staging based on the LOCS III scale,” Mitchell A. Jackson, MD, said at the American Society of Cataract and Refractive Surgery annual meeting.
The retrospective, two-armed, single-surgeon study included 322 eyes, of which 229 eyes were femtosecond treated and 93 eyes were not pre-softened with a laser, he said.
One day postoperatively, patients in the femtosecond group had an average uncorrected visual acuity about three lines better than patients in the non-femto group. Additionally, patients in the femtosecond group had a 16% lower corneal edema grade than the non-femto group, but the different was not statistically significant, Jackson said.
“Fluid dynamics revealed moderate improvements when femto laser was employed,” he said. – by Robert Linnehan

This retrospective study covers more cases with femtosecond than non-femto cases, and on the first postoperative day, visual acuity was reported to be better in femto cases. This can be directly attributed to the pre-softening of nuclear fragments with femto that needed less phaco energy than the non-femto group. Although the results were not statistically significant, it would be useful to know the number of cases that were stage grade 3 or harder on the LOCS III scale and the results in eyes with denser nuclei. With the multiburst mode, it is essential to regulate the power settings as bursts can be delivered at varying intervals with further foot pedal depression. The power modulation is critical to maximizing the success of phacoemulsification.
