Constellation Vision System Recall: Problems Could Interrupt Eye Surgery
Federal regulators are warning that the Constellation Vision System, a medical device used to perform eye surgery, has hardware and software problems that could result in an injury for patients.
The FDA announced this week that a Constellation Vision System recall issued earlier this month constitutes a Class 1 medical device recall, indicating that the defect has a substantial likelihood to result in serious injury or death. The recall was first issued by Alcon Research Ltd., the manufacturer, after it identified both software and hardware problems with the system.
Problems with the device could cause unexpected power loss and shut downs of the machines, unintended system errors, touchscreens that become unresponsive and performance problems. These could lead to a patient suffering a serious eye injury or blindness, the FDA concluded.

The devices were sold between September 1, 2008 and April 30, 2010.
The FDA says that Alcon sent a letter to customers on July 2, informing them of the problems. Although the FDA and Alcon classify it as a recall, the devices will not be removed from healthcare facilities. Instead, Alcon representatives will visit all of the customers and update the software and replace the touchscreen circuit board.
