Interventions/Control_1

Harvest of the oral mucosal tissue is conducted at the central operation room or the operation room of the outpatient unit of department of ophthalmology in Tohoku University Hospital. The safety of harvest process of the oral mucosal tissue is evaluated carefully. The oral mucosal tissue is harvested from the cheek mucosa after local anesthesia. The size of the oral mucosal tissue would be 5 mm square and 3-4 mm in depth. The site of harvest is sutured for blood stanching and observed during the early follow-up period.
