Abstract Details


The purpose of the study was the evaluation of the visual function after cataract surgery with bilateral trifocal vs extended range of vision IOL (ERV).


Prospective, nonrandomized study after implantation of 380 IOL: 300 trifocal IOL(group 1) vs 80 ERV IOL (group2).


Distance, intermediate and near visual acuity (VA) were evaluated. Distance and near stereoacuity and contrast sensitivity were also performed. Patients’ satisfaction (spectacle independence, photic phenomena and visual satisfaction) was assessed by a self-report questionnaire.


Study that included 380 IOL, majority female, mean age 64 years; mean IOL power +21,2D. Percentage of patients with distance VA > 1,0 was 80% (group 1) and 73,33% (group 2); intermediate 85,96% (group 1) and 76,47% (group 2), near VA > J1 82,76% (group 1) and 52,94% (group 2). Trifocal IOL had more spectacle independence reading a newspaper and using a computer (73% vs 34,6% and 82,6% vs 34,6%, respectively). Halos were superior in group 1; glare and light sensitivity in group 2. Distance visual satisfaction was superior in group 2 (91,56% vs 100%), near and global in group 1 (91,56% vs 83,33% and 96,62% vs 91,67%, respectively; intermediate satisfaction was equal in both groups.


In conclusion, the IOL studied enable good VA in different distances and good visual function but have some differences regarding visual symptoms and visual satisfaction.
