The purpose of this study is to assess visual outcomes following bilateral cataract surgery and the implant of a FineVision® trifocal intraocular lens (IOL).
Methods: Prospective, 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.
Results: Mean 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.
Conclusions: Bilateral FineVision IOL implant achieved a full range of adequate vision, satisfactory contrast sensitivity, and a lack of significant adverse photic phenomena.
