Clinical Results And Patient Satisfaction Following Bilateral Implantation Of A New Enhanced Monofocal Iol

To report  the clinical outcomes and patient satisfaction following bilateral implantation of Vivinex^TM Impress enhanced monofocal IOL.

Brar Eye Hospital, Bathinda, Punjab.

This ongoing prospective study included 60 eyes of 30 eligible patients who underwent bilateral phacoemulsification with implantation of the Hoya Vivinex^TM Impress enhanced monofocal IOL (Model XY1-EM) for age related cataract, with both eyes being targeted for emmetropia. Three months post-operatively, binocular visual outcomes for distance, intermediate and near vision along with subjective questionnaire for quality of vision and dysphotopsia symptoms was obtained. 

The mean age of the participants was 64±8.4 years. Three-month post-op, the mean values for binocular uncorrected distance VA (UDVA), intermediate VA (UIVA) at 66 cm, near VA (UNVA), corrected distance visual acuity (CDVA), distance corrected intermediate VA (DCIVA) and distance corrected near VA (DCNVA) were 0.05±0.07, 0.26±0.05, 0.37±0.07, 0.01±0.03, 0.24±0.05, and 0.35±0.06 respectively. Mean residual spherical equivalent was 0.07±0.23 D. Patients reported excellent satisfaction regarding performing far and intermediate distance activities and quality of their vision, without any significant complaints of positive dysphotopsias or reduction in contrast sensitivity.

Early experience suggests that the Vivinex Impress enhanced monofocal IOLs provide excellent distance and intermediate vision results at 66cm, without any compromise in visual quality due to significant dysphotopsias or reduced contrast sensitivity.
