Arms Assigned Interventions
Active Comparator: Patch
The operative eye will be patched.
Procedure: Patch or bandage contact lens
Patients will be given a patch or a bandage contact lens at the conclusion of pterygium excision surgery.
Experimental: Bandage Contact Lens
The operative eye will have a bandage contact lens
Procedure: Patch or bandage contact lens
Patients will be given a patch or a bandage contact lens at the conclusion of pterygium excision surgery.

Ages Eligible for Study:   19 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

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)
