Abstract:
PURPOSE: To evaluate clinical outcomes after cataract surgery with bilateral implantation of the diffractive trifocal intraocular lens (IOL). METHODS: Forty-four eyes of 22 patients were analyzed in the present study from July 2014 to December 2014. Phacoemulsification with bilateral implantation of an AT Lisa tri 839 MP IOL (Carl Zeiss Meditec, Jena, Germany) was performed. Over a 6-month follow-up, the main outcome measures were uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) at 80 cm, uncorrected near visual acuity (UNVA) at 40 cm, and spherical equivalent refraction. Visual quality and patient satisfaction were evaluated using a Quality of Vision questionnaire. Finally, the defocus curve was measured. RESULTS: The mean monocular UNVA, UIVA, and UDVA were 0.23, 0.22, and 0.02 log MAR at 1 month, 0.21, 0.20, and 0.01 log MAR at 3 months and 0.20, 0.22, and 0.01 log MAR at 6 months postoperatively, respectively. The mean binocular UNVA, UIVA, and UDVA were 0.16, 0.12, and 0.0 log MAR at 1 month, 0.15, 0.11, and 0.0 log MAR at 3 months and 0.15, 0.13, and 0.0 log MAR at 6 months postoperatively, respectively. Twelve patients reported glare and 17 patients reported halo. Defocus curve showed best visual acuity results at 0.0 D and second peak at - 2.5 D. The intermediate-vision values were stable. CONCLUSIONS: Diffractive trifocal IOL provided excellent distance, intermediate, and near visual outcomes.
