In this study the investigators will be comparing two different types of anesthetic, a numbing eye drop and a numbing gel, to test if they are equally effective or if one has a better outcome in terms of the level of comfort you experience one hour and one day after your surgery. The two medications are commonly used and appear to be equally effective for other types of eye surgery, such as cataract surgery. This study will show if one type of anesthesia is preferred over another by patients getting LASIK. Before your LASIK procedure, you will be given a short questionnaire to determine the baseline comfort of your eyes. In the operating room, one type of anesthetic will be put in one eye, and the other medication will be put in the other eye. Which anesthetic you get in each eye will be chosen in a random way (similar to flipping a coin). After your LASIK surgery, the investigators will ask you if you felt more comfort in your right eye, your left eye, or if they were equal, and the investigators will ask you the same survey questions that were asked prior to your LASIK to get more details about your experience.

Study summary:

Outcome measures involve comparing the right eye and left eye for severity of 12 different symptoms, that are recorded in severity on a 1-5 scale. A score of 1 means no symptoms and 5 means severe. The 12 measurements include sharp pain, dull ache, pain during movement, stinging sensation, itching, light sensitivity, watery eyes, dry eyes, sandy sensation, pressure sensation, decreased vision, and blurry vision.
