Successful use of conjunctival flaps to prolong survival of type I keratoprosthesis in severe bilateral chemical burns: two case reports

Introduction: This report describes the use of conjunctival flaps to enable survival type I keratoprosthesis (KPro) in two cases bilateral severe total limbal stem cell deficiency (LSCD) following chemical burns. Presentation case: Two patients had a history injury with lime. On examination, presenting vision was light perception hand motions and both conjunctivalized ocular surfaces symblepharon. A modified technique used, where corneal pannus dissected lifted off as an inferior fornix-based flap. followed by standard surgical KPro. The flap then secured over device optical opening made weeks later. Both stable visual acuity 20/20 at 2–7 years follow-up. Discussion: In LSCD adnexal involvement, KPro has unsatisfactory long-term because risk repeated epithelial breakdowns stromal ulceration. With innovative approach described this report, can be successfully used for sustainable improvement presence surface disease symblepharon. Conclusion: Conjunctival along KPros improve give outcomes blindness due advanced damage.
