  • Causa
    This action is an update to the previous ‘urgent recall for product correction' and 'hazard alert' letters issued by alcon in february 2012 and july 2012 for the acrysof cachet phakic lens that described updates to the directions for use (dfu) and advised healthcare professionals of an acute adverse event for endothelial cell loss (ecl). recently alcon conducted a further data analyses of the five-year global study looking at the safety and efficacy of the acrysof cachet phakic lens. whilst the study data showed high efficacy as defined by visual acuity, approximately 1% of implanted lenses showed a risk for accelerated corneal endothelial cell loss (ecl) that led to explantation of the lens. the cause of ecl in individual patients is not well understood and is likely multi-factorial. however, analyses have indicated a trend for higher rates of ecl in:- patients with smaller eyes (those implanted with lens model l12500) - patients self-identified as being asians.

Strict adherence to these requirements by patients will help to timely identify ECL and determine the appropriate treatment plan.
