Abstract Details

Purpose:

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).

Setting:

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

Methods:

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.

Results:

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.

Conclusions:

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.
