RT Journal Article SR Electronic T1 Comparative analysis of objective and subjective outcomes of two different intraocular lenses: trifocal and extended range of vision JF BMJ Open Ophthalmology JO BMJ Open Ophth FD BMJ Publishing Group Ltd SP e000497 DO 10.1136/bmjophth-2020-000497 VO 5 IS 1 A1 Emilio Pedrotti A1 Francesco Carones A1 Pietro Talli A1 Erika Bonacci A1 Federico Selvi A1 Alice Galzignato A1 Andrea Besutti A1 Alessandra De Gregorio A1 Giorgio Marchini YR 2020 UL http://bmjophth.bmj.com/content/5/1/e000497.abstract AB Objective To evaluate objective and subjective outcomes after bilateral implantation of two different multifocal intraocular lenses, which correct pseudophakic presbyopia in an adequate and homogeneous population court.Methods and analysis Fifty patients were evaluated at 3 months after bilateral implantation, at the Eye Clinic of University of Verona and at the Carones Ophthalmology Center Milano, as follows: Tecnis Symfony (25 patients), Alcon PanOptix (25 patients). Main outcomes were uncorrected and best-corrected distance visual acuity (UDVA and BCVA) at 4 m, 60 cm (best distance corrected intermediate visual acuity (BDCIVA) and uncorrected intermediate visual acuity), 40 cm (best distance corrected near visual acuity (BDCNVA) and uncorrected near visual acuity (UNVA)), objective refractive outcome, defocus curve, contrast sensitivity (Modulation Transfer Function (MTF) cut-off), optical quality (Strehl ratio), aberrometry (root mean square RMS 4 mm), subjective quality of life (National Eye Institute Refractive Error Quality of Life score (NEI-RQL-42 score) test).Results Symfony and PanOptix showed BCVA and UDVA comparable results. Symfony presented significant better outcomes at BDCIVA (p=0.001), while PanOptix showed better performances at BDCNVA and UNVA (p=0.01). Symfony achieved better results in RMS 4 mm (p=0.024) and in MTF cut-off (p=0.041). In the questionnaire NEI-RQL-42, PanOptix presented better scores in ‘near vision’ and ‘spectacles independence’, whereas Symfony in ‘symptoms’ and ‘clarity of vision’.Conclusion Both intraocular lenses are valid options to avoid pseudophakic presbyopia, even though they present different features which make them unique. Symfony allows patients to achieve a better objective and subjective quality of vision and contrast sensitivity; PanOptix provides better outcomes in near vision and spectacles independence requirements.
