Visual Function after 150 Trifocal Intraocular Lens (IOL) Implantation
After cataract surgery it is important not only the improvement in visual acuity but also the effect of vision in patient's life, called visual function (VF).
The purpose of the study was the evaluation of the visual function after cataract surgery with bilateral trifocal intraocular lens.
Prospective, nonrandomized study after implantation of 150 trifocal IOL (AT LISA tri 839MP®).
Distance, intermediate and near vision 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 and Conclusion
Study that included 150 trifocal IOL. 74,6% of patients were female, mean age was 65,2 years (range 43-85) and mean IOL power was +21,60 dioptres (range 12-29D). All patients achieved distance and intermediate vision of 20/30 or better; 96% achieved 20/30 for near vision. Patients reported spectacle independence in 83,7% of their daily activities Visual symptoms such as glare and light sensitivity were mild or inexistent in the majority of patients. Halos were reported as inexistent or mild 32% and 30% of patients, respectively. Overall satisfaction was high regarding global, distance, intermediate and near vision (98%, 96%, 92% and 90%, respectively). In conclusion, trifocal IOL enable excellent distance, intermediate and near visual acuity associated with high visual function and spectacle independence.
