MARRAKECH, Morocco — The latest IOL model in the Oculentis family, the Femtis Comfort IOL, specifically designed for femtosecond laser-assisted cataract surgery, showed improved performance in mesopic conditions without vision disturbances in a study.

“It seems that this lens could further improve the outcomes of FLACS,” Detlef Holland, MD, said at the European Society of Cataract and Refractive Surgeons Winter Meeting.

The Femtis Comfort IOL is a plate haptics lens with four additional haptics, of which two are enclavated anteriorly to the capsule within the capsulotomy. This new feature provides stable placement in the eye over time, an important asset with this type of high-tech, presbyopia-correcting optics.

“This haptic system allows the lens to clamp into the capsulorrhexis. The additional maneuver needs a small learning curve, but an experienced surgeon will be able to implant the lens in no more than half a minute,” Holland said.

In his clinic, he is currently testing the results of the Femtis Comfort in an ongoing prospective study, with 28 eyes of 14 patients included so far. Femtosecond laser-assisted surgery was performed in this group. The results at 1 year were compared by Holland with those of a previous study evaluating the outcomes of the Oculentis Lentis Comfort model in 66 eyes of 33 consecutive patients operated with the standard phacoemulsification procedure.

“The two lenses have a similar optic, designed to achieve the best uncorrected distance and intermediate visual acuity, minimizing nighttime visual disturbances. The refractive and UCVA outcomes were comparable, but the Femtis group had a slightly better defocus curve and showed better results in a questionnaire measuring all types of dysphotopsia,” Holland said.

He hypothesized that the reason for this may be the better centration, the missing overlap of the capsulotomy over the optic and the more anterior position of the Femtis Comfort.

A larger number of patients will be compared at the end of the ongoing study for further examination. by Michela Cimberle
