Purpose
To evaluate the visual, refractive, and safety outcomes following the implantation of trifocal and/or trifocal toric 1stQ AddOn (Medicontur) intraocular lenses (IOLs) in pseudophakic patients for the correction of residual refractive errors, astigmatism, and presbyopia.
Setting
Institut Ophtalmologique de l'Ouest Nantes France
Methods
This prospective clinical study included 22 eyes from 11 patients (mean age: 64 ± 9.5 years; 54.5% female) who underwent secondary implantation of a 1stQ Multifocal AddOn IOL. Preoperative and postoperative assessments at 6 months included uncorrected and corrected distance visual acuity (UDVA, CDVA), uncorrected and corrected intermediate visual acuity (UIVA, DCIVA), as well as uncorrected and corrected near visual acuity (UNVA, DCNVA). A binocular defocus curve analysis, contrast sensitivity test, and patient satisfaction evaluation were also conducted.
Results
At 6 months postoperatively, the mean monocular UDVA significantly improved by 0.17 LogMAR (p=0.0073) to 0.16 ± 0.18 LogMAR, binocular UDVA was 0.08 ± 0.14 LogMAR. UIVA was 0.23 ± 0.1 LogMAR monocularly and 0.13 ± 0.07 LogMAR binocularly, while UNVA was 0.16 ± 0.14 LogMAR monocularly and 0.08 ± 0.1 LogMAR binocularly. The binocular defocus curve demonstrated peak visual acuity values of -0.02 ± 0.02 LogMAR at far distance, 0.07 ± 0.03 LogMAR at intermediate distance, and 0.03 ± 0.02 LogMAR at near distance, indicating effective visual performance across all distances. Contrast sensitivity was significantly reduced as expected with the lesn technology.
Patient satisfaction was high, particularly for near and intermediate vision.
Conclusions
The implantation of the 1stQ AddOn IOL significantly improved uncorrected visual acuity at all distances, with a notable benefit in intermediate and near vision. The binocular defocus curve confirmed good visual performance across all focal distances. Although a decrease in contrast sensitivity was observed, patient feedback remained highly positive, particularly for near vision. The safety profile remained generally favorable. Despite a slight reduction in CDVA, overall visual performance and patient satisfaction suggest that the 1stQ AddOn IOL is a safe and effective option for optimizing refraction in pseudophakic patients.
