Purpose

To assess the spectacle’s independence and subjective quality of vision perceived by pseudophakic patients implanted bilaterally with a combination of two models of a new inverted meniscus intraocular lens (IOL), Art40 and Art70 (ArtIOLs, Voptica SL, Murcia, Spain) which improve the overall off-axis optical quality and induce different amounts of negative spherical aberration to increase the depth of focus.

Setting

Oftalvist clinic of Murcia, Spain; University of Murcia, Spain

Methods

Ten cataract patients were implanted bilaterally with Art40 and Art70 IOLs to induce low and high values of negative spherical aberration respectively. In addition to the measurements of visual acuity at different distances, 1-3 months after the last surgery, patients were surveyed for the spectacle independence at different distances using the Patient Reported Spectacle Independence Questionnaire (PRSIQ) and for the frequency, severity and bothersome (with four levels of score) of 10 negative visual symptoms (glare, haloes, starburst, etc.) using the Quality of Vision (QoV) questionnaire.

Results

The binocular combination of the two lenses provided mean values of uncorrected visual acuity of 0.00 LogMAR at far and better than 0.05 LogMAR at intermediate (66 cm) and near (40 cm) distances.

The PRSIQ results showed that 9 of the 10 patients didn’t use glasses for far and intermediate tasks and 8 patients didn’t use glasses at near distance.

From QoV surveys, for each symptom, 8 or more patients never reported that symptom, and when they did, the levels of severity and bothersome were low. Only one patient reported glare and halos but with low impact in his daily tasks.

Conclusions

Most patients implanted with the bilateral combination of Art40 and Art70 IOLs were spectacle independent for all daily activities and all viewing distances. Given the refractive nature of these IOLs the patients did not report any relevant negative visual symptoms.
