Intraocular lens (IOL) - hydrophilic acrylic - opacification
(intraocular lens (IOL) - hydrophilic acrylic) opacification of intraocular lens (IOLs) may occur following intracameral use of alteplase. (MDA/2010/008)
Device
Intraocular lens (IOL) – hydrophilic acrylic.
Problem
Opacification of IOLs may occur following intracameral use of alteplase (recombinant tissue plasminogen activator, r-tPA).
The MHRA has been notified of 5 reports of the opacification of hydrophilic acrylic IOLs from 1 UK hospital. Opacification was noted between 5 months and seven years after alteplase treatment.
A study carried out by the hospital concluded that IOL opacification may be caused by intracameral use of alteplase to treat fibrinous membranes after cataract surgery.
Alteplase is a drug indicated for use in acute stroke, myocardial infarction, and pulmonary embolism. It is not licensed for intracameral use.
This could potentially be a problem with all hydrophilic acrylic IOLs. No manufacturing fault was found with the IOLs in this study.
Details of the study were presented as a poster at UKISCRS, 2009 (United Kingdom and Ireland Society of Cataract and Refractive Surgeons). The poster is attached in the appendix to this alert.
Action
- Ensure that all relevant staff are made aware of this issue.
- Report all IOL opacification incidents to the MHRA.
