London - World No 3 Rory McIlroy has undergone laser surgery to correct his vision as he sets his sights on more success next year.
The 26-year-old Northern Irishman posted a picture of himself on Instagram wearing protective glasses and saying that the procedure went smoothly.
"Human version of the dreaded K-9 cone... Only for sleeping though!" McIlroy posted, referring to the protective cones worn by some dogs.
"Laser eye surgery went well."
McIlroy, who has four major titles to his name, formerly played with contact lenses, which he has been wearing since he was 11.
He missed part of this season after damaging ankle ligaments playing football, but finished on a high note when he won last month's season-ending DP World Tour Championship and defended his Race to Dubai title.
