The purpose of this study is to determine if patching the eye or a bandage contact lens along with Tylenol #3 is more effective for pain control following pterygium surgery.

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)
