Abstract Details



Purpose:

The aim of this study is to assess the visual outcomes under photopic and mesopic conditions after bilateral implantation of a new trifocal intraocular lens.

Setting:

Department of Ophthalmology, Hospital Santo António - CHP, E.P.E - Porto, Portugal

Methods:

Patients with bilateral implantation of AT LISA 839MP were evaluated 3 months after surgery. Monocular and binocular uncorrected and best distance-corrected near, intermediate and far visual acuity were measured under photopic and mesopic conditions. Contrast sensitivity function was assessed under photopic conditions. Patient satisfaction and dysphotopsia incidence were recorded.

Results:

Distance visual acuity was mantained in photopic and mesopic evaluations. Both intermediate (0.01ḟ0.05 vs. 0.1ḟ0.04, P=0.015) and near (-0.02ḟ0.04 vs.0.08ḟ0.04, P=0.009) visual acuity decreased under mesopic conditions. Binocular uncorrected near vision after surgery was better than preoperative corrected near vison (-0.01ḟ0.04 vs. 0.12ḟ0.04, P=0.02). Bilateral and monocular contrast sensitivity function were similar at all spatial frequencies. Dysphotopsias were mild without compromising daily activities. All patients rated their satisfaction with uncorrected near, intermediate and distance visual acuity as good or very good.

Conclusions:

Our study strongly suggests that this trifocal lens provides good distance, intermediate and near uncorrected visual acuity and can allow spectacle-independence in pseudophakic patients.
