Popis: Objective To evaluate clinical outcomes of a trifocal intraocular lens using femtosecond laser-assisted cataract surgery (FLACS), digital tracking (DT), and intraoperative aberrometry (IA). Setting One site (Abbotsford, B.C., Canada) Design Retrospective, single-surgeon study. Methods This was a retrospective, single-surgeon study examining 200 eyes of 100 bilaterally implanted patients. Eligible participants were those presenting with visually significant cataracts or as a candidate for clear lens extraction who were interested in implantation of a diffractive toric or non-toric intraocular lens. Preoperative and postoperative data were collected for manifest refraction spherical equivalent (MRSE), refractive astigmatism (RA), and monocular uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), and uncorrected near visual acuity (UNVA). Results Mean postoperative manifest refraction spherical equivalent (MRSE) was 0.006 ± 0.27 D. The absolute prediction error was 0.50 D or less in 88.0% (176/200) of eyes. Postoperative RA was 0.50 D or less in 98.5% (197/200) of eyes. Postoperative UDVA was 0.10 logMAR or better in 86% (172/200) of eyes, and 66.0% (132/200) of eyes were 0.00 logMAR or better. Postoperative UIVA was 0.10 logMAR or better in 99.5% (199/200) of eyes, and 95.0% (190/200) of eyes were 0.00 logMAR or better. Postoperative UNVA was 0.10 logMAR or better in 91.5% (183/200) of eyes, and 73.5% (147/200) of eyes were 0.00 logMAR or better. Conclusion The results demonstrate that trifocal implantation with FLACS, DT, and IA can provide excellent refractive and visual outcomes.
