MAUDE Adverse Event Report: RAYNER INTRAOCULAR LENSES LIMITED C-FLEX

Model Number 570C

Device Problem Material Opacification (1426)

Patient Problem Visual Impairment (2138)

Event Date 11/14/2022

Event Type  malfunction  

Event Description

On (b)(6) 2022, rayner received notification from a us healthcare facility of an event that occurred following implantation of a c-flex 570c iol.The event description provided states that post-operatively the onset of iol opacification has been observed leading to explantation of the iol.

Manufacturer Narrative

The reference (b)(4) has been allocated to this case by rayner.The patient underwent implantation of the c-flex 570c iol in their right eye prior to 2015.The patient medical history received identifies that the patient has diabetes and primary open angle glaucoma, categorised as severe.Iol implantation was not combined with any other ocular surgery; however, the patient is reported to have required multiple surgeries in the post-operative period, as detailed below: (b)(6) 2016: ahmed aqueous shunt implantation, tutoplast graft, right eye, primary open angle (b)(6) 2019: baerveldt aqueous shunt implantation, left eye, primary open-angle glaucoma (b)(6) 2019: scleral reinforcement with patch graft, left eye, primary open-angle glaucoma iol opacification was observed for the first time on (b)(6) 2017 and was assessed as being progressive in nature.Opacification led to a decline in patient visual acuity and the c-flex 570c iol was explanted on (b)(6) 2022.Rayner has requested the return of the explanted iol for analysis.Secondary calcification affects many manufacturers and is a phenomenon that is not fully understood; it is known that it stems from changes in the eye's environment due to patient comorbidity, secondary surgeries and potentially other, poorly understood interactions: off label use of intracameral alteplase (actilyse) (rtpa), multifactorial, high phosphate content ophthalmic viscoelastic devices , repeated exposure to intracameral air, raised intraocular pressure, excessive post-operative inflammation, complicated, traumatised eyes, as a result of direct contact between the iol surface and the exogenous gas or substance, a metabolic change in the anterior chamber due to the presence of exogenous gas/substance in the eye or an exacerbated inflammatory reaction after multiple surgical procedures, trauma or repeat surgery involved in re-bubbling potentially disrupting the blood aqueous barrier, increasing concentration of calcium ions.Rayner ifus contraindicate "active ocular diseases (e.G., chronic severe uveitis, proliferative diabetic retinopathy, chronic glaucoma not responsive to medication".The patient's medical history and repeat ocular procedures for the treatment of their pre-existing medical conditions is likely to be a contributory factor to the onset of opacification in this case.
