It was reported that an implanted extended depth of focus (edof) intraocular lens (iol) in the left eye (os) was associated with inadequate near and intermediate vision despite excellent distance visual outcomes.The reported visual difficulties impacted the patient's reading and work activities.The physician reported dissatisfaction with the lens performance and indicated that the lens had been explanted.The patient did not experience a loss of ¿2 lines of best spectacle-corrected visual acuity (bscva) and was not overcorrected or under corrected.Pre-operative refraction was reported as -3.00 -0.50 x 178 with a pre-operative bscva of 20/30+2.Post-operative uncorrected visual acuity (ucva) was reported as distance visual acuity (dva) 20/20 and near visual acuity (nva) j8.Post-operative refraction was +0.25 -0.25 x 053, with a post-operative bscva of 20/20 and an intended target refraction of +0.04.Post-operative findings reportedly suggested a questionable hyperopic target or landing.The explanted lens was exchanged for a non-johnson & johnson trifocal intraocular lens (iol) with a power of +15.0 diopters (d) and add powers of +1.75 d and +3.50 d.No additional unplanned or medical interventions were indicated.Following the lens exchange, the patient reported improvement in near vision and was satisfied with the outcome.Post-exchange distance visual acuity (dva) was reported as 20/25, and near visual acuity (nva) was j1, indicating excellent near vision.The explanted lens was not retained and is not available for return or evaluation.No further information was provided.This report is limited to the patient implanted with the lens model den00v, serial number (b)(6), who underwent lens explantation.The physician reported similar concerns in few patients; however, no additional explant events are included in this report.If additional explants are reported, separate mdr submissions will be made, as appropriate.
