How long does the effect of the anaesthetic eye drops lasts after PRK surgery?
The effect lasts for about 3-4 hours, after which, depending on individual sensitivity, you may feel like there is a foreign body in your eye, or even experience pain. Taking oral painkillers helps ease these symptoms. The discomfort disappears when epithelialization is complete. The first night is usually the worst, and afterwards, symptoms gradually wane.
