What are the risks?

Your eye may be red and sore when the anaesthetic wears off. If this happens, you should take normal painkillers. Your sight may be blurred for a few days or even a few weeks, but it should settle down to how it was before the laser treatment was performed. In 30% of cases, patients need repeat treatment with the laser to achieve low pressure in the eye. It is rare to have any serious complications after this procedure. In some cases reduced vision may last for up to six weeks. The pressure may be too high or low following treatment. In very rare cases, persistently very low pressure can cause permanent loss of vision and alter the cosmetic appearance of the eye.
