I am having myopia and astigmatism. And also when I wear lens it start irritating in left eye. And lenses make my eyes dry. And so I want to know that can I have lasik surgery? and what are its side effects and recovery time?

See to that you are using contact lenses from a good company. Try to use coopervision contact lenses they are supposed to be very comfortable. You can use preservative free eye drops like eyemist e/d when you are using contact lenses to reduce irritation before undergoing lasik a test called corneal topography will be done if the results are fine then you can undergo lasik without any problem. Recovery time will be 1 week to 10 days. Most common side effect is haloes around headlights during driving at night time. Mild irritation is experienced by few.
