Abstract
BackgroundIn recent years new models of intraocular lenses are appearing on the market to reduce requirements for additional optical correction. The purpose of this study is to assess visual outcomes following bilateral cataract surgery and the implant of a FineVision® trifocal intraocular lens (IOL).MethodsProspective, nonrandomized, observational study. Vision was assessed in 44 eyes of 22 patients (mean age 68.4 ± 5.5 years) before and 3 months after surgery. Aberrations were determined using the Topcon KR-1 W wave-front analyzer. LogMAR visual acuity was measured at distance (corrected distance visual acuity, CDVA 4 m), intermediate (distance corrected intermediate visual acuity, DCIVA 60 cm) and near (distance corrected near visual acuity, DCNVA 40 cm). The Pelli-Robson letter chart and the CSV-1000 test were used to estimate contrast sensitivity (CS). Defocus curve testing was performed in photopic and mesopic conditions. Adverse photic phenomena were assessed using the Halo v1.0 program.ResultsMean aberration values for a mesopic pupil diameter were: total HOA RMS: 0.41 ± 0.30 μm, coma: 0.32 ± 0.22 μm and spherical aberration: 0.21 ± 0.20 μm. Binocular logMAR measurements were: CDVA −0.05 ± 0.05, DCIVA 0.15 ± 0.10, and DCNVA 0.06 ± 0.10. Mean Pelli-Robson CS was 1.40 ± 0.14 log units. Mean CSV100 CS for the 4 frequencies examined (A: 3 cycles/degree (cpd), B: 6 cpd, C: 12 cpd, D: 18 cpd) were 1.64 ± 0.14, 1.77 ± 0.18, 1.44 ± 0.24 and 0.98 ± 0.24 log units, respectively. Significant differences were observed in defocus curves for photopic and mesopic conditions (p < 0.0001). A mean disturbance index of 0.28 ± 0.22 was obtained.ConclusionsBilateral FineVision IOL implant achieved a full range of adequate vision, satisfactory contrast sensitivity, and a lack of significant adverse photic phenomena.Trial registrationEudract Clinical Trials Registry Number: 2014-003266-2.
Highlights
In recent years new models of intraocular lenses are appearing on the market to reduce requirements for additional optical correction
Given that the intraocular lens (IOL) in our patients were implanted in both eyes to optimize vision, distance, intermediate and near visual acuity were measured binocularly using the EDTRS scale with distance correction under the same photopic conditions
This study examines the outcome of bilateral implantation of this IOL and provides far, intermediate and near visual acuities determined with best distance correction in photopic conditions, defocus curves for photopic and mesopic conditions, contrast sensitivity values assessed using two methods, along with halometry and aberrometry data
Summary
In recent years new models of intraocular lenses are appearing on the market to reduce requirements for additional optical correction. The purpose of this study is to assess visual outcomes following bilateral cataract surgery and the implant of a FineVision® trifocal intraocular lens (IOL). The FineVision® trifocal diffractive IOL (Physiol, Liège, Belgium) combines two diffractive structures that are adjusted to offer +3.50 D addition for near vision and +1.75 D addition for intermediate vision (http://www.physiol.eu/ en/multifocal-iol/finevision/). The present study was designed to determine visual and refractive outcomes in patients undergoing cataract surgery and the implant of a FineVision IOL in both eyes Few studies have assessed the FineVision IOL [4,5], especially in terms of aberrometry outcomes.
