Abstract Details


The introduction of Femtolaser assisted Capsulorhexis seems to be a big step forward in the effective lens position (ELP) in lens surgery. Does this also have a positive effect on lens tilt and visual acuity in different IOL models?

We investigated 60 eyes from 30 patients up to 9 months after manual and Femtolaser assisted capsulorhexis. Subjective refraction, Capsular overlap, IOL centration and IOL tilt was measured with a Video Purkinje Meter designed by Kaymak and Schaeffel. VA and aberrometry was documented 1 week and up to 9 month after surgery. Femtolaser capsulorhexis was performed with the femtolaser. All cases were performed by one surgeon. No intraoperative complications occured.


The capsular overlap was more perfect and complete in the FAC group regarding the covered area and circularity. HOA, IOL centration and IOL tilt was the same in both groups. Visual recovery seems to be slightly faster in the FAC group.


Due to the perfect capsular overlap in the FAC group we do expect a long term positive effect on ELP and lens tilt in the next years and therefore continue investigating these parameters. Especially in complex optical IOL systems such as aspheric, toric and multifocal IOLs we expect further clarifying results, concerning whether FLAC provides a significant advantage.
