%X Objetivo: comparar la efectividad del autoinjerto conjuntival y el injerto de membrana amni車tica en la cirug赤a del pterigi車n primario en el Instituto Cubano de Oftalmolog赤a "Ram車n Pando Ferrer" de septiembre de 2009 a septiembre de 2010. M谷todos: estudio prospectivo, comparativo y aleatorio. El universo estuvo constituido por 80 pacientes (80 ojos) con diagn車stico de pterigi車n primario que se les realiz車 escisi車n quir迆rgica de la hiperplasia fibrovascular nasal primaria. Se dividieron en 2 grupos al azar simple. Al grupo A (40 ojos) se le implant車 injerto de membrana amni車tica y al grupo B (40 ojos) autoinjerto de conjuntiva. Resultados: en seis meses de seguimiento se presentaron cuatro recurrencias (10 %) en el grupo A y solo dos casos en el grupo B (5 %). En ninguno de los pacientes hubo complicaci車n. Fue m芍s efectivo el autoinjerto conjuntival. Conclusiones: la recidiva fue m芍s frecuente en la cirug赤a con membrana amni車tica aunque no existi車 una diferencia significativa. Se consideran ambas t谷cnicas efectivas en esta afecci車n. Objective: to compare the effectiveness of the conjunctival autograft and the amniotic membrane graft in the primary pterygium surgery at ※Ram車n Pando Ferrer§ Cuban Institute of Ophthalmology from September 2009 to September 2010. Methods: a prospective, random and comparative study. The universe was composed by 80 eyes from 80 patients diagnosed with primary pterygium. They had undergone the surgical excision of a primary nasal fibrovascular hyperplasia. They were divided in two single-randomized groups (A and B); the group A patients (40 eyes) were implanted with amniotic membrane graft whereas those of group B (40 eyes) were implanted with conjunctival autograft. Results: during the 6 month follow-up, 4 recurrences were reported (10 %) in group A and only 2 in group B (5 %). No complications were presented in both groups. The conjunctival autograft was more effective. Conclusions: the relapse was more frequent in amniotic membrane surgery than in conjunctival autograft, although the difference was not significant. Both techniques are considered as effective for this pathology.
