Stem cell conjunctival transplantation for prevention of recurrence and film stability in advanced pterygium

To study the efficacy of stem cell conjunctival transplantation in prevention of recurrence and its effect on improvement of tear film stability in cases of advanced pterygium. 14 eyes of 14 patients with advanced pterygium were treated by excision followed by stem cell conjunctival graft transplantation. Follow up for recurrence and tear film stability was done for at least 6 months after surgery. All patients showed improved breakup time of tear film. None of the patients showed any evidence of recurrence. Only one patient [7.1%] had conjunctival recurrence. Stem cell conjunctival transplantation seems very effective in prevention of recurrence as well as improvement of tear film stability in treating patients with advanced pterygium
