Stability and visual outcomes of the capsulotomy-fixated FEMTIS-IOL after automated femtosecond laser-assisted anterior capsulotomy.

Abstract Purpose To evaluate stability and performance of a new monofocal anterior capsulotomy-fixated intraocular lens (IOL) (FEMTIS, Teleon Surgical B.V., Spankeren, Netherlands) after femtosecond laser-assisted cataract surgery (FLACS). Design Prospective, multicenter, interventional, non-comparative case series Methods FLACS with FEMTIS IOL was performed in 336 eyes of 183 cataract patients with fixation of the IOL to the anterior capsulotomy followed up for 12 months. Examination included: uncorrected distance visual acuity (UDVA), best corrected (CDVA), subjective refraction, IOL-centration, posterior capsule opacification (PCO) and investigators satisfaction questionnaire. Results At 12 months, mean IOL rotation was 1.50±1.76° and decentration 0.14±0.14 mm from baseline (day of surgery). Mean horizontal IOL tilt was 0.70±0.60° and vertical 1.15±1.06° relative to the baseline (crystalline lens). Mean distance between IOL and iris was 0.32 mm to 0.36 mm for all measured meridians. Mean UDVA was 0.12±0.14 logMAR (range -0.20 to 0.54 logMAR), mean CDVA -0.01±0.09 logMAR (range -0.30 to 0.20 logMAR). Mean spherical equivalent (SE) was 0.35±0.53 D and 98% (n=235) of eyes were within ±1.0 D. Median PCO score was 1 with a Nd:YAG laser rate of 3.1% after 12 months. Most surgeons were very satisfied (median score: 1) with surgery and implanted IOL. Conclusions Implantation of FEMTIS IOL provided excellent visual and stable refractive outcomes. IOL decentration was very low compared to other published studies and showed an exceptional high in-the-bag stability over a 12-month period. This lens benefits from femtosecond laser capsulotomies. It can be positioned very predictably and offers an optimal platform for toric and multifocal IOL optics.
