Event Description
|
It was reported that customer observed calcified model za9003 21.5 diopter tecnis monofocal iol (intraocular lens) after implanting in patient's right eye (od).This is reportedly due to aqueous makeup in patient's eye, but not necessarily in lens material.Through follow-up, patient's od has early calcification changes.Current visual acuity is 20/30.The doctor felt that these events are related to the lens itself, but rather to the metabolism of the patient.The doctor reported he will do an exchange in the near future.No additional information provided.This report pertains to right eye.A separate report will be submitted for the left eye.

This supplemental report pertains to right eye (od).A separate report will be submitted to left eye (os).Based on new information received, the (b)(6) female patient had bilateral 3-piece silicone lens implants in 2007, surgeries were uneventful, patient's visual acuity post-op was 20/20.She had a history of elevated calcium, workup was unremarkable with no etiology identified.The doctor felt to be secondary to the excessive calcium intake combined with vitamin d supplements.In 2016, patient was referred for posterior capsule opacification with symptoms included difficulty in reading and reading road signs.Patient's visual acuity was 20/50 od.Prescribed medications in 2016 were atorvastatin, digoxin, losartan, omeprazole, kcl, triamterene/hctz, and zyrtec.The patient underwent iol exchange od finally followed by os.The silicone lens was lens was cut, removed from capsular bag and extracted.A replacement lens model, z9003 monofocal iol was placed in the capsular bag leaving a well-centered iol and clean bag.The surgery was uneventful.Her postop medications were topical antibiotic, steroid, topical nsai and a subtenon kenalog injection and her vision after the exchange was od -1.00 20/20.The patient maintained good vision until (b)(6) 2018.She was presented with complaints of decreased reading vision and night halos with visual acuity of 20/30 od.Slit lamp examination revealed posterior capsule opacification (pco) on both eyes (ou) as it appeared to be cloudiness on the posterior aspect of the lenses, especially in os.If explanted; give date: the date was not specified, but the best estimate date is during 2016 for od explant.(b)(4).All pertinent information available to johnson & johnson surgical vision, inc.Has been submitted.
