According to a release on the tournament's website, Goosen is suffering from blurred vision as the result of recent corrective laser surgery.
'I'm obviously very sad that I am unable to defend my title,' said Goosen in the release. 'I came all this way to play, but unfortunately the eye is causing a problem. I went to Dubai yesterday and the advice was to go to London for treatment.
'I have had laser treatment before, seven years ago, and felt I needed a touch up, which I had done 10 days ago. But there has been a bit of growth with a fibre in the left eye. It is a very simple procedure to take it out and the advice was to do it sooner. It is a shame as I love this event, love this course. I think I pulled out of the Scottish Open once with a back injury but that is all. You are never happy leaving a tournament without teeing it up.'
Goosen has not won a tournament since beating Nick O'Hern by one shot and Ernie Els by two in last year's Qatar Masters.
