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.
Objectif
Évaluer les résultats cliniques de l'implantation d'une lentille intraoculaire trifocale
réalisée par chirurgie de la cataracte au laser femtoseconde (CCLFS) comprenant un
suivi numérique (SN) et une aberrométrie intraopératoire (AI).
Nature
Étude rétrospective portant sur un seul chirurgien.
Méthodes
Il s'agissait d'une étude rétrospective qui examinait 200 yeux de 100 patients ayant
fait l'objet d'une implantation bilatérale réalisée aux mains d'un seul chirurgien.
Les sujets admissibles devaient présenter des cataractes visuellement significatives
ou être candidats à l'extraction du cristallin clair et souhaiter l'implantation d'une
lentille intraoculaire diffractive (torique ou non). Au nombre des données préopératoires
et postopératoires recueillies, citons l’équivalent sphérique de la réfraction manifeste
(MRSE), l'astigmatisme réfractif (AR) de même que l'acuité visuelle de loin non corrigée
(UDVA), l'acuité visuelle intermédiaire non corrigée (UIVA) et l'acuité visuelle de
près non corrigée (UNVA), toutes monoculaires.
Résultats
L’équivalent sphérique de la MRSE postopératoire moyen se chiffrait à 0,006 ± 0,27
D. L'erreur de prédiction absolue était de 0,50 D ou moins dans 88,0 % des yeux (176/200).
L'AR postopératoire était de 0,50 D ou moins dans 98,5 % des yeux (197/200). L'UDVA
postopératoire s’élevait à 0,10 logMAR ou mieux dans 86 % des yeux (172/200), et 66,0
% des yeux (132/200) ont obtenu un résultat de 0,00 logMAR ou mieux. L'UIVA postopératoire
était de 0,10 logMAR ou mieux dans 99,5 % des yeux (199/200), et 95,0 % des yeux (190/200)
ont obtenu un résultat de 0,00 logMAR ou mieux. L'UNVA postopératoire se chiffrait
à 0,10 logMAR ou mieux dans 91,5 % des yeux (183/200), et 73,5 % des yeux (147/200)
ont obtenu un résultat de 0,00 logMAR ou mieux.
Conclusion
Ces données démontrent que l'implantation d'une lentille intraoculaire trifocale réalisée
par CCLFS et comprenant un SN et une AI peut donner d'excellents résultats réfractifs
et visuels.
