Persistent Intraocular Residue with the Use of Dexycu® in Cataract Extraction: A Case Series

Purpose: The objective of this article is to report 8 cases of persistent IOL residue associated with the use of Dexycu® in the context of cataract surgery and then to subsequently describe each patients clinical course. Observations and Presentation: Between 2020-2021, persistent residue was noted in 8 eyes of 7 patients who received Dexycu® implants after cataract surgery. The residue was identified an average of 1.63 months after surgery (range 0.20-4.23). A subsequent procedure removed the residue from the intraocular lens; the average time to the follow-up procedure after surgery was 4.71 months (range 1.90-11.20). Conclusions and Importance: The Bausch and Lomb intraocular lenses seem to be predisposed to a Dexycu® persistent opacification, however correlation does not equate with causation. This article documents cases of persistent IOL residue with the use of Dexycu® and the MX60 lenses and its toric varieties. Further evaluation is necessary to elucidate the mechanism and risk factors for this occurrence.
