Your pre-operative eye exam and consultation with your surgeon are very important parts of your LASIK experience and often determine your satisfaction with your visual outcome.
During the pre-operative exam, your surgeon will ask you questions about your overall health and carefully examine your eyes to determine if you are a good candidate for laser vision correction. In particular, your surgeon will evaluate the front surface of your eye to make sure the cornea is healthy and will check for signs of dry eye.
Also, measurements of the shape and thickness of your cornea will be performed to make sure you have enough corneal tissue for a full and safe correction of your refractive error. In some cases, a different type of vision correction surgery may be recommended if your surgeon feels that procedure will be safer or more effective for your particular needs.
It's also very important to discuss with your surgeon what you expect your vision will be like after LASIK. Ask your surgeon to describe the likely outcome of your procedure and the risks involved so you have realistic expectations and can make an informed decision about whether LASIK is a good choice for you.
