Abstract
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.
