Clinical outcomes with a trifocal intraocular lens: a multicenter study.

PURPOSE: To evaluate the clinical results and safety obtained with a new type of multifocal intraocular lens (IOL) using a trifocal design to achieve pseudoaccommodation. METHODS: A pilot observational study of patients with a trifocal IOL (FineVision; PhysIOL, Liege, Belgium) implanted by 1 of 12 surgeons between March and December 2010. Visual outcomes that were assessed postoperatively included uncorrected and corrected distance, intermediate, and near visual acuity. RESULTS: One hundred ninety-eight eyes of 99 patients were analyzed. Patients were observed for an average of 6.44 ± 4.67 months (range: 0.2 to 17 months). Preoperative corrected distance visual acuity was 0.22 ± 0.26 logMAR. At the final follow-up visit, corrected distance visual acuity was 0.01 ± 0.10 logMAR, uncorrected distance visual acuity was 0.01 ± 0.06 logMAR, uncorrected intermediate visual acuity was 0.08 ± 0.10 logMAR, and mean uncorrected near visual acuity was 0.00 ± 0.04 logMAR. Postoperative binocular uncorrected distance visual acuity was 0.01 ± 0.07 logMAR, uncorrected intermediate visual acuity was 0.06 ± 0.08 logMAR, and uncorrected near visual acuity was -0.03 ± 0.04 logMAR. Postopeative mean residual sphere was 0.21 ± 0.48 diopters (D), with a residual cylinder of -0.24 ± 0.31 D. Postoperative spherical equivalent was 0.11 ± 0.36 D. CONCLUSIONS: The results demonstrated that the trifocal FineVision IOL is able to restore near, intermediate, and distance visual function.

Ophthalmological findings in congenital cytomegalovirus infection: when to screen, when to treat?

Cytomegalovirus (CMV) is the leading cause of known congenital viral infections. Approximately 90% of congenitally infected newborns exhibit no clinical abnormalities at birth. In 5% to 15%, a wide spectrum of clinical signs is present at birth. Ophthalmological signs are seen in a large percentage of symptomatic patients but rarely in otherwise asymptomatic infants. Chorioretinitis, optic atrophy, and cortical visual impairment are the most frequent causes of visual problems in congenitally infected infants. There is no clear consensus in the literature on screening or treatment modalities concerning the ophthalmological aspects of congenital CMV. Further prospective studies are needed to set up guidelines for ophthalmological screening and treatment of infants with congenital CMV.

Visual and refractive outcomes after implantation of a fully diffractive trifocal lens.

BACKGROUND: The purpose of this study was to record the visual outcomes of patients treated by six surgeons after implantation of a trifocal lens. METHODS: The setting for this study comprised six ophthalmology units and eye clinics in Belgium and France, with a coordinating center in France, and data management and statistical analysis in France and Belgium. Ninety-four eyes from 47 patients were implanted with a trifocal FineVision(®) intraocular lens by six surgeons. Monocular and binocular, uncorrected and best distance-corrected, and photopic and mesopic visual acuity was measured, as well as the defocus curve between +4 D and -4 D with best distance correction. RESULTS: Near and far monocular visual acuities were similar to the data published after bifocal intraocular lens implantation. Intermediate vision was improved, and was demonstrated by scores of near visual acuity as well as far visual acuity with defocus -1.5 D-add lens. Far vision is maintained in mesopic conditions. CONCLUSION: The trifocal intraocular lens provides good far, intermediate, and near visual acuity.
