The bare sclera technique is still in use by many surgeons worldwide in spite of the attendant high recurrence rate. Any modification of this well known procedure may be more widely acceptable if associated with lower recurrence.
The bare sclera technique was modified by performing a partial thickness sclerectomy from the pterygium bed. This modified technique was applied to 23 eyes of 17 patients with primary pterygium. The subjects were followed up for varying periods between 8 to 31months to determine the recurrence rate of pterygium after surgical excision and other complications.
Initial observation showed that the recurrence occurred in two eyes of two patients of a series who were followed up for a minimum of six months and up to thirty-one months. Two other eyes developed suture granuloma. There were no other complications observed in the remaining twenty eyes of fifteen patients.
Partial thickness sclerectomy when performed with standard bare sclera technique seems promising and may improve the results of pterygium excision by bare sclera method.
尽管裸巩膜技术伴随高复发率，但全球仍有许多外科医生在使用。如果能降低复发率，这种广为人知的手术方法的任何改进可能会被更广泛地接受。
通过从翼状胬肉床进行部分厚度巩膜切除术对裸巩膜技术进行改良。将这种改良技术应用于17例原发性翼状胬肉患者的23只眼中。对受试者进行了8至31个月不等的随访，以确定手术切除后翼状胬肉的复发率及其他并发症。
初步观察显示，在一组至少随访6个月至31个月的患者中，有两名患者的两只眼睛出现复发。另外两只眼睛出现缝线肉芽肿。在其余15例患者的20只眼中未观察到其他并发症。
采用标准裸巩膜技术进行部分厚度巩膜切除术似乎很有前景，可能会改善裸巩膜法切除翼状胬肉的效果。
