Healthy volunteers

Inclusion criteria

* Primary pterygium (no previous surgeries or radiotherapy) requiring excision due to ocular discomfort or disruption in vision * Size of pterygium greater than 2.5 mm over the cornea (pterygia smaller than this do not result in much postoperative eye pain) * Ability to understand the nature of the procedure and to complete all measurement requirements * Adults (age greater than 18)

Exclusion criteria

* Ocular surface disease apart from pterygium (such as severe dry eye, corneal disease, scarring from previous infection, radiotherapy, inflammatory diseases or trauma) * Patients who have had previous ocular surface surgery * Contraindications to local anesthetics (such as known allergy) * Pregnancy (as the risk to the fetus with the use of topical antibiotic drops and local anesthetics are not known) * Patients already on systemic analgesics for any other reason (such as rheumatoid arthritis) * Allergy to codeine (in order to standardize the systemic analgesic used so that we can compare the effect of bandage contact lens versus 24 hour patching)
