Femtosecond Laser Assisted Cataract Surgery Vs Conventional Cataract Surgery: Evaluation Of The Capsular Bag Performance Of A Novel Aspheric Hydrophobic Intraocular Lens

To evaluate the influence of a femtosecond laser assisted cataract surgery (FLACS) on the post-operative capsular bag performance using a novel aspheric hydrophobic intraocular lens

Kepler University Clinic, Linz, Austria

Patients scheduled for bilateral cataract surgery were included in this randomized study with bilateral comparison. All patients received the same aspheric hydrophobic intraocular lens (CT Lucia 621P/PY with a novel step vault design, Carl Zeiss Meditec AG, Germany). Randomisation was used to perform group allocation to be either in the FLACS group (Victus, Lomb & Bausch, Germany) or in the conventional “manual” cataract surgery group. At the one and six months follow up visits two different swept source optical coherence tomography measurements (IOL Master 700, CZM and CASIA2, Tomey GmbH, Germany) were performed as well as auto refraction, subjective refraction and best corrected and uncorrected visual acuity.

In total 100 eyes of 50 patients were included in this study. After 6 months, there was no relevant difference in anterior chamber depth (4.57 ± 0.23 mm and 4.58 ± 0.27 mm; p = 0.627), tilt (4.19 ± 1.66° and 5.03 ± 2.04°; p = 0.543) or decentration (0.31 ± 0.23 mm and 0.28 ± 0.14 mm; p = 0.350) after conventional cataract surgery and FLACS retrospectively. The postoperative mean spherical equivalent showed a slight hyperopic shift with no relevant difference in both cohorts (+ 0.12 ± 0.51 dpt and + 0.19 ± 0.46 dpt; p = 0.350).

The investigated IOL shows an equal postoperative positional stability and refractive performance after 6 months postsurgery with no significant difference between FLACS or conventional cataract surgery.
