Abstract Details


In this study, an intraocular lens with extended depth of focus (EDOF-IOL with addition +1.5 D) enclavated in the capsulotomy after FLACS in cataract surgery was evaluated. Visual acuity, subjective refraction, PCO rate and Centration was investigated.

In an ongoing prospective multicenter study 24 eyes of 12 cataract patients with expected postoperative corneal astigmatism below 0.75D were included so far. After a femtolaser assisted automated capsulotomy of 5.0mm, a EDOF-IOL with 4 additional haptics for rhexis fixation was implanted (FEMTIS Comfort, FB-313MF15; OSD Medical GmbH, Berlin, Germany). The capsulotomy was centered on the pupil center. Preoperatively, intraoperatively ,1-7 days, 6-8 weeks and 6 months postoperatively, examinations of uncorrected and best-corrected far, intermediate and near visual acuity, subjective refraction were evaluated. The visual acuity from distance to near vision was determined using a defocus curve.


No complications occurred intra- or postoperatively. Best-corrected distance visual acuity improved from 0.25 logMar (± 0.18) preoperatively to 0.00 logMar(± 0.09) 6-8 weeks postoperatively, 0.00logMar (± 0.11) 6 months postoperatively. Corrected intermediate visual acuity was 0.00 LogRad(± 0.09) after 6-8 weeks, 0.00 logRad(± 0.11) after 6 months postoperatively. SE after 6 months postoperatively is +0.21 D (± 0.11). The defocus curve shows a decimal visual acuity of at least 0.5 over a dioptric range of 3.5 D up to a near distance of 50cm. A treatment-relevant, visus-reducing poststar after 12 months is not present postoperatively.


The rhexis-fixed FEMTIS Comfort IOL with extended depth of focus shows good visual results over a visual range from a distance to 50 cm. The results regarding safety of this new IOL design are very good. The PCO rate after 6 months postoperatively is low. Longer follow up will be examined.
