Abstrakt: Purpose: To compare long-term intraocular lens (IOL) decentration and tilt following femtosecond laser-assisted cataract surgery (FLACS) and conventional surgery using swept-source anterior segment ocular coherence tomography (SS-ASOCT).
Methods: In this retrospective cross-sectional study, all patients underwent FLACS or conventional cataract surgery. Those with a minimum of 12-months follow-up since surgery were included. Patients with surgical complications were excluded. Demographics, preoperative ocular measurements (axial length, anterior chamber depth), and postoperative measurements [corrected distance visual acuity (CDVA), autorefraction, keratometry, IOL type] were collected. Postoperative IOL tilt and decentration were compared using SS-ASOCT between patients with FLACS and conventional cataract surgery. Subgroup analysis was conducted to analyze tilt and decentration by haptic type (single-piece vs. three-piece).
Results: A total of 188 eyes were included [110 (58.5%) in the FLACS group and 78 (41.5%) in the conventional group]. No differences were observed between the FLACS and conventional groups regarding preoperative parameters. FLACS resulted in less IOL decentration compared to conventional cataract surgery (170 μm vs. 240 μm, p = 0.002). No statistically significant differences were observed between the FLACS and conventional groups in the magnitude and axis of IOL tilt. Both groups had a trend of IOL tilt toward the inferotemporal aspects. Moreover, no difference regarding postoperative CDVA, spherical equivalent, and keratometric astigmatism was observed.
Conclusions: FLACS resulted in significantly better long-term IOL centration than conventional surgery with manual capsulotomy. No significant difference in IOL tilt or postoperative CDVA was observed between FLACS and conventional cataract surgery.
