Trachoma, an ocular infection caused by C. trachomatis, is the second leading infectious cause of blindness worldwide. Years of repeated infection with C. trachomatis cause the eyelid to scar and contract and ultimately to rotate inward such that the eyelashes rub against the eyeball and abrade the cornea (trichiasis). The World Health Organization (WHO) has endorsed a multi-faceted strategy to combat trachoma which includes surgery to repair lids distorted by trachoma (trichiasis) in imminent danger of vision loss. Current evidence suggests that long-term success rates of trichiasis surgery are less than optimal due to variation in surgical technique. Previous research by this study team has demonstrated that shorter incisions have a higher rate of trichiasis recurrence. In addition, observations by this team's oculoplastic surgeon have led to the hypothesis that granuloma formation and lid contour abnormalities may result from current surgical practices. The objective of this study is to compare outcomes of trichiasis surgeries performed with the newly developed trachomatous trichiasis (TT) clamp versus surgeries following standard technique (bilamellar tarsal rotation procedure or BLTR).
