Laser eye surgery is a painless procedure that reshapes the front of your eye - the cornea - to correct any visual problems. As a result, you will no longer need to wear glasses or contact lenses.

Refractive errors can be divided into four categories:

		1		Myopia or short sight The range treated is usually ? 1.00 D to ?10.00D			3		Astigmatism or a mis-shapen cornea Up to 6.00D can be treated
		2		Hypermetropia or long sight The range treated is usually 0.50D to 4.00D			4		Presbyopia or the need for reading glasses due to problem focusing up close
