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.
