Scottish singer KT Tunstall has undergone tests in preparation for laser eye surgery to correct her sight.
The star, who had a global hit with her song Suddenly I See, has told fans she wants to undergo the procedure, and she attended a clinic on Wednesday for a preliminary check.
In a post on her Twitter.com blog, she writes, "Getting tests to see if I can get laser eye surgery, and nursey just dilated my pupils! Woohoo! I can't read!"
