Comparison Between Bandage Contact Lens and Pressure Patching for The Erosion Area and Pain Scale in Corneal Erosion Patients

Comparison Between Bandage Contact Lens and Pressure Patching for The Erosion Area and Pain Scale in Corneal Erosion Patients

This research aims to compare between bandage contact lens and pressure patching in reducing size of erosion area and pain scale in corneal erosion patients as well as its complications.

This is a randomized open-label clinical trial in patients with mechanical corneal erosion. Subjects were selected to use bandage contact lens (Senofilcon A) or pressure patching. All subjects received combination of Polymyxin B, Neomycin, and Gramicidin eye drops and 0,5% Tropicamide eye drops. Evaluation was done 24 hours after treatment

Inclusion Criteria:

• aged 17-55 years
• onset of corneal erosion < 48 hours
• corneal erosion due to mechanical injury
• extensive corneal erosion > 3 mm2

Exclusion Criteria:

• bilateral corneal erosion
• corneal erosion due to chemical or thermal injury
• history of systemic analgesic use within 1 week prior to the examination or topical analgesics within 1 hour before the examination
• history of systemic or topical antibiotics within 1 week prior to the examination
• other abnormalities due to trauma
• palpebral or eyelashes position abnormalities
• anterior segment infections
• tear break-up time < 7 seconds in the contra lateral eye
