Recurrent pterygium is a common postoperative complication of pterygium surgery, the postoperative recurrence rate is about 1.44% and needs careful treatment. At present, surgical is the main and most effective treatment of recurrent pterygium. Among various surgical methods, autologous conjunctival transplantation is regarded as the first choice in normal conditions. However, the scope of conjunctival transplantation is positively correlated with the degree of ocular surface damage. Therefore, our research aimed to use micro conjunctival transplantation（1.5mm×3.0mm） to reconstruct limbal conjunctiva and amniotic membrane to cover the whole pterygium resection area to better protect conjunctival sac and ocular surface.
To observe the effect of micro-conjunctival autografting combined with amniotic membrane transplantation on the postoperative recurrence, complications and ocular surface symptoms among patients with recurrent pterygium.
