A drug that is often used to help treat prostate-related problems has been noted as risking serious complications after cataract surgery.
A study of over 95,000 men that had cataract surgery found that 7.5 per cent of those who had taken Flomax in the previous fortnight suffered a complication such as retinal detachment or inflammation.
Researchers from St Michaels Hospital in Toronto, who carried out the study, said: "We believe this is the first large study with an adequate study design to describe this effect.
"It is unclear whether drug discontinuation prior to surgery reduced this risk.
"Because the combination of cataract surgery and tamsulosin exposure is relatively common, patients should be properly appraised of the risks of drug therapy."
According to the NHS, cataracts are the main cause of impaired vision in the world, with around 30 per cent of over 65s in the UK suffering from the condition.
