Abstract Details


Extended depth of focus (EDOF) intraocular lenses (IOL) have been shown to increase levels of spectacle independence but may be associated with unwanted visual disturbances such as glare and haloes.  The purpose of this study is to evaluate visual  outcomes and patient satisfaction after implantation of a new hydrophobic asymmetric-refractive extended depth of focus (EDOF) IOL.


All implantations and follow up visits were performed at the the  Ambulatory Surgical Center, Peregrine Eye and Laser Institute, Makati City, Philippines


Forty eyes underwent uncomplicated cataract surgery with implantation of a novel, asymmetric-refractive EDOF IOL (Acunex Vario, Teleon Surgical B.V. Netherlands). Follow up examinations were performed at 1, 3 and 6 months after surgery.  The main outcome measures were:  uncorrected distance, intermediate and near visual acuity (UDVA, UIVA, UNVA); corrected distance visual acuity (CDVA);  distance-corrected intermediate and distance-corrected near visual acuity (DCIVA, DCNVA); defocus curves; contrast sensitivity;  posterior capsular opacification (PCO) grading, YAG capsulotomy rates; and patient satisfaction questionnaire (Haloes and Glare).


The mean +/- standard deviation monocular, postoperative UDVA was 0.09 +/- 0.08 logMAR, UIVA was 0.18 +/- 0.13 and UNVA was 0.31 +/- 0.16. The mean monocular postoperative CDVA was 0.04 +/- 0.08 logMAR, DCIVA was 0.13 +/- 0.11 and DCNVA was 0.26 +/- 0.15 logMAR. The defocus curves showed excellent distance and good intermediate visual acuity. Contrast sensitivity and PCO grading showed excellent results comparable to known values after monofocal IOL implantation.  None underwent YAG capsulotomy. Patient questionnaires demonstrated high patient satisfaction and little or no Haloes & Glare which were predominantly described as not disturbing.


A novel, asymmetric-refractive IOL provided very good extended depth of focus, spectacle independence for far and intermediate distances and excellent contrast sensitivity.  PCO rates and visual dysphotopsias were comparable to those observed for monofocal IOL's.
