Abstract Details

Purpose:

The aim of this pilot study was to offer the interim report of visual, refractive and aberrometric outcomes in patients implanted with a new intraocular lens based on an innovative multifocal design presenting a maximum addition of +3.00 D, likewise to compare clinical results of preoperative and postoperative data.

Setting:

Vissum Miranza, Alicante, Spain

Methods:

Pilot longitudinal study composed by patients implanted with the new intraocular lens Accunex Vario (Teleon) due to cataract or desire to eliminate spectacle correction. Patients were undergone to a complete optometric and ophthalmologic examination before and after the surgery including measuring of visual acuities (distance, intermediate, near), subjective refraction, contrast sensitivity assessment and ocular aberrometry by a pyramidal aberrometer (Osiris, CSO). Postoperative outcomes were compared with preoperative data by Wilcoxon test using the software Statistical Package for the Social Science (SPSS, IBM). The present is the interim report of a pilot investigation.

Results:

The study included 12 eyes of 6 patients (mean age of 57.3±5.7 years). Postoperative visual outcomes were a mean uncorrected distance visual acuity of 0.77±0.25, uncorrected near visual acuity of 0.51±0.21, corrected distance visual acuity of 0.91±0.14 and corrected near visual acuity of 0.78±0.13 (all measurements in decimal notation). Postoperative refractive outcomes were a mean spherical equivalent of 0.01±0.67D and an addition of 0.81±0.92D. All visual and refractive parameters improved comparing to preoperative status (p<0.05) especially addition power (0.81±0.92 vs. 2.32±0.23, p: 0.011). Mean high-order aberrations were 0.69±0.51m distributed in coma 0.26±0.06m, trefoil 0.33±0.11m, and spherical aberration 0.06±0.03m.

Conclusions:

The Accunex Vario intraocular lens, which incorporates varifocal technology in their design, improves the visual performance of patients after their implantation. In addition, it provides a particular aberrometric pattern that may be associated to their optical design. These results should be confirmed in future studies increasing the sample size.
