Abstract
Purpose :
To evaluate the clinical outcomes and the complementarity of the new set of multifocal intraocular lenses (IOLs) Artis Symbiose (Cristalens Industrie, France).
Methods :
Twenty patients were implanted with the Artis Symbiose Mid IOL in the dominant eye, and the Artis Symbiose Plus IOL in the contralateral eye after phacoemulsification. Inclusion criteria were: age over 50 years, cataract or refractive lens exchange patients, pupil diameter between 2 and 4 mm in photopic conditions, DEWS ≤ 2 in the scale of dry eye severity. Exclusion criteria were any pathology or condition that could affect the outcomes and the performance of the measurements and expected postoperatory residual astigmatism ≤ 0.75 D. Monocular and binocular defocus curves were assessed at 1-2 months with ETDRS charts at 4 m. Distance, intermediate (90 and 70 cm), and near (40 cm) visual acuity, contrast sensitivity (CSV-1000, VectorVision, USA), light disturbances (LDA, Binary Target, Portugal), and patient satisfaction (VF-14 questionnaire) were assessed at least 6 months after surgery.
Results :
Mean monocular defocus curves of both eyes met at 2.00 D of defocus. The binocular defocus curve showed a visual acuity of 0.10 logMAR or better from 0 to 3.00 D of defocus (Figure 1). Uncorrected distance, intermediate (90 cm and 70 cm), and near visual acuity were -0.03 ± 0.08, 0.03 ± 0.13, 0.03 ± 0.11, and 0.06 ± 0.10 (mean ± SD) logMAR respectively. Contrast sensitivity was within normal values for patients age. Binocular light distortion index was 9.93 ± 5.30 % and patient satisfaction 93.37 ± 7.31 %.
Conclusions :
Monocular defocus curves demonstrated the complementarity of the Artis Symbiose Mid & Plus IOLs. The mean binocular defocus curve showed a depth-of-field of 3.00 D with visual acuity 0.1 logMAR or better. Uncorrected visual acuity was good at all evaluated distances. Contrast sensitivity was normal and patient satisfaction was very high.
