Did not play a competitive stroke play event between the European Open in May 2009 and the Alfred Dunhill Links Championship in October after suffering from blurred vision caused by fluid behind the retina in his left eye. After banishing memories of a frustrating 2009 season, Karlsson started and finished 2010 in superb fashion, winning the Commercialbank Qatar Masters presented by Dolphin Energy in his second event and ending the season with victory at the lucrative Dubai World Championship presented by DP World, beating Ian Poulter in a play-off. The latter win lifted him to sixth in the Race to Dubai. Another highlight of 2010 came at the BMW PGA Championship in May, when he shot a course record 62.
