In pterygium excision procedures, the subconjunctival injection of xylocain is regarded as an uncomfortable and painful step in the procedure. While already being studied in other ophthalmic procedures such as glaucoma surgery (7), application of topical lidocaine gel is likely to minimize pain. The gel has a longer surface contact time due to its consistency, providing not only a longer anesthetic effect, but protecting the corneal surface against desiccation, when compared to eye drops. The investigators hypothesize that Ophtesic 2% lidocaine gel is as effective as an anesthetic in pterygium excision as subconjunctival injection, while providing more comfort during surgery and less corneal dryness afterwards. Our goal is to compare both the anesthetic and corneal surface effect of topical 2% lidocaine gel to subconjunctival injection of xylocaine 2% solution with 0.125 epinephrine in pterygium surgery: * Compare the patients pain during and after surgery * Compare corneal dryness after surgery. * Evaluate possible secondary events
