Abstract Details


To compare the visual and refractive outcomes after implantation of a trifocal intraocular lens (IOL), considering distance, near and intermediate vision.


BMI Southend Private Hospital


This study comprised patients who had bilateral implantation of the AT LISA Trifocal IOL or PhysIOL FineVIsion Trifocal IOL after phacoemulsification. The main outcome measures were Uncorrected (UDVA) and Best Corrected Distance Visual Acuity (BCDVA) measured in logMAR. Near visual acuity (NVA) and Intermediate visual acuity (IVA) were measured in logRAD using the Radner reading charts. Preferred working distance and reading range were measured. A short quality of life questionnaire was completed by the patients.


20 patients (40 eyes) were included. 10 patients implanted with PhysIOL FineVIsion and 10 patients with AT LISA Trifocal. At 6 months post-operative, the FineVision group had Mean Spherical refraction was 0.28DS ±0.33 (SD) and astigmatic refraction was -0.30DCḟ0.19(SD).Mean UDVA was 0.09LogMAR ḟ0.09 and BCDVA was 0.00 LogMARḟ0.08. Near and Intermediate Visual Acuity mean values were 0.13 and 0.40 respectively. Preferred Reading distance was 34.5cms and mean range was 23.3 to 50.7cms. The AT LISA group had Mean Spherical refraction of 0.42DS ±0.12 (SD) and astigmatic refraction was -0.50DCḟ0.23(SD). Mean UDVA was 0.02LogMAR ḟ0.05 and BCDVA was -0.06LogMARḟ0.03. Near and Intermediate Visual Acuity mean values were 0.14 and 0.40 respectively. Preferred Reading distance was 31.5cms and mean range was 23.5 to 47.5cms. Both IOL models resulted in good distance, intermediate and near vision with no statistically significant differences between models. Reading range with the FineVision was better than the LISA Trifocal.Mild dysphotopsia was reported in both groups specifically halos at night. No patient in either group wore spectacles and all reported they were very satisfied since implantation of the trifocal lenses.


Post operative visual acuity was good at distance, intermediate and near with both IOL models, but there is no significant difference between the trifocal lenses. No patients had Refraction of more than 1.00DS post op and no spectacles were used by any of the patients. Mild dysphotopsia was reported by all patients. All patients reported that they were pleased with their vision and quality of life after trifocal lens implantation. No statistically significant difference could be established in any of the outcome measures between the AT LISA Trifocal IOL and the PhysIOL FineVIsion.
