Purpose
To evaluate the clinical outcomes of a trifocal (MIOL), diffractive binocular intraocular lens system (Artis Symbiose, Cristalens Industrie, France), where one lens exhibits an extended depth of focus profile for intermediate vision (Artis Mid) and the other lens for near vision (Artis Plus).
Setting
Methods
The first results of this ongoing clinical study include 7 patients who underwent phacoemulsification due to cataract with implantation of the MIOL (Artis Symbiose, Cristalens Industrie, France). Subjective refraction, corrected and uncorrected visual acuity (VA), monocular and binocular [logMar] for distance, intermediate and near vision, as well as a binocular and best-corrected defocus curve analysis were evaluated 3 (n=7) and 6 (n=5) months after surgery.
Results
Mean binocular visual acuity in logMAR (±SD) at 3/ 6 months were UDVA 0.03 (±0.08)/ 0.03 (±0.09); UIVA -0.05 (±0.05)/ 0.02 (±0.05); UNVA 0.10 (±0.13)/ 0.12 (±0.10); CDVA 0.01 (±0.07)/ 0.00 (±0.07); DCIVA -0.04 (±0.07)/ -0.02 (±0.04); DCNVA 0.09 (±0.10)/ 0.11 (±0.07). The binocular distance-corrected defocus curve at 3 months showed a continuous visual acuity of 0.20 or better in the range of +0.75 to -2.75 diopters of defocus. After 6 months a continuous visual acuity of 0.20 or better was shown in the range of +1,0 to -2.5 diopters of defocus.
