Abstract/OtherAbstract:
<p><bold>Purpose:</bold> To evaluate visual and refractive outcomes, contrast sensitivity, and quality of vision after cataract surgery with the implantation of a new modality of trifocal intraocular lens (IOL).</p><p><bold>Methods:</bold> This case series comprised 30 patients who had bilateral implantation of the AT.LISA tri 839 MP trifocal IOL after phacoemulsification for either cataract or refractive lens exchange surgery. Uncorrected (UDVA) and corrected monocular distance visual acuity (CDVA) using a logMAR chart, binocular uncorrected (UNVA) and corrected near visual acuity (CNVA) (40 cm and patients' preferred distance) using the Radner Reading Charts, distance-corrected intermediate visual acuity (DCIVA) (70 cm), a binocular defocus curve, contrast sensitivity (CS) with the Pelli-Robson test, and subjective quality of vision by a short questionnaire were evaluated at 1, 3, and 6 months postoperatively.</p><p><bold>Results:</bold> At 6 months, mean values of 0.05 ± 0.07 and -0.02 ± 0.05 logMAR were obtained for monocular UDVA and CDVA, respectively. Mean values of 0.16 ± 0.07, 0.12 ± 0.07, and 0.16 ± 0.07 logRAD were obtained for binocular UNVA, CNVA, and DCIVA, respectively. Significant changes were only detected in monocular CDVA (p&lt;0.01) and UDVA that improved between 3 and 6 months postoperatively (p = 0.01). A visual acuity level of 0.2 logRAD could be seen in binocular defocus curves between +1.00 and -3.00 D. At 6 months, mean photopic and mesopic CS were 1.52 ± 0.11 and 1.54 ± 0.11. Regarding the questionnaire, almost all patients were satisfied with their distance, intermediate, and near vision. Difficulties associated with photic phenomena decreased significantly over time.</p><p><bold>Conclusions:</bold> The AT.LISA trifocal IOL provides excellent uncorrected distance, intermediate, and near visual outcomes.</p>
