Abstract Details


Determine whether intermediate visual outcome is in accordance to what is expected from trifocal (AT LISA tri 839 MP) intraocular lenses. Study distance, intermediate and near refractive outcomes and quality of vision of trifocal intraocular lens implantation.


Hospital Universitario Donostia, San Sebastian (SPAIN)


Prospective clinical study. 20 cataractous eyes of 10 patients underwent cataract surgery and trifocal intraocular lens (IOL) implantation. IOLMaster, visual acuity (logMAR) and refractive data were registered preoperatively, 1 month, 3 months and 6 months after surgery. OQAS and quality of life (QoL) questionnaire were performed 1 month, 3 months and 6 months after surgery. Statistical analysis was performed using Microsoft Excel 2010.


Six months after surgery, mean monocular uncorrected VA (± standard deviation [SD]) was -0.01±0.07, 0.11±0.08, 0.17±0.11 and 0.10±0.09 for 6 m, 80 cm, 60 cm and 40 cm respectively. Binocular uncorrected mean VA (±SD) was -0.04±0.05, 0.01±0.11, 0.09±0.06 and 0.10±0.12 for 6 m, 80 cm, 60 cm and 40 cm respectively. Binocular best distance corrected VA was -0.06±0.05, -0.05±0.07, 0.08±0.06 and 0.04±0.10 for the mentioned distances. Differences between binocular corrected and uncorrected VA were only significant at near and far distances. Spherical equivalent (SE) was -0.09±0.16. MTF and OSI results were 33.85±10.81 and 1.47±0.46. No patient reported clinically significant halos and all of them would repeat the same IOL implantation.


In our experience, visual acuity and refraction remain constant and stable from the first until the sixth month after the implantation of an AT LISA tri 839 MP trifocal lens, providing spectacle freedom at all distances in any light condition and improving intermediate vision.
