ResumenObjetivoDeterminar la eficacia y seguridad del uso de adhesivo tisular de fibrina en la queratoplastia penetrante (QPP) comparándola con la técnica estándar.Material y métodosSe captaron pacientes candidatos a QPP dividiéndolos aleatoriamente en 2 grupos de 10; al primero se le realizó QPP con 8 puntos simples de nailon 10-0, aplicando adhesivo tisular en la herida quirúrgica, y al segundo se le aplicó la técnica estándar usando 16 puntos simples, registrando el tiempo quirúrgico de cada procedimiento. Se midió agudeza visual mejor corregida y astigmatismo queratométrico a los 3 y 6 meses postoperatorios.ResultadosEl tiempo quirúrgico promedio para el grupo de adhesivo fue 36.1min vs. 55.1 min en el grupo control (p=<0.0001). El astigmatismo queratométrico promedio a los 3m fue −3.69 D para el grupo de adhesivo vs. −4.75D en el grupo de QPP estándar (p=0.245) y −2.88D vs. −3.44D a los 6m (p=0.246). La agudeza visual mejor corregida promedio fue LogMAR 0.37 para el grupo de adhesivo vs. LogMAR 0.39 (p=0.822) a los 3m y LogMAR 0.20 vs. LogMAR 0.25 a los 6m, respectivamente (p=0.334). Ningún paciente presentó complicaciones relacionadas con el procedimiento quirúrgico.ConclusionesLa QPP con 8 puntos simples y adhesivo tisular parece ser una técnica segura, que requiere menor tiempo quirúrgico y que permite al paciente una recuperación visual más rápida comparada con la técnica estándar.AbstractObjectiveTo determine safety and efficacy of the use of fibrin glue in penetrating keratoplasty (PKP) compared with the standard technique.Material and methodsCandidates to PKP were captured, dividing them in 2 groups of 10 patients each; in the first group, PKP using 8 nylon 10-0 sutures and fibrin glue was performed, while in the other, standard keratoplasty with 16 sutures was performed, registering surgical time in each case. Best corrected visual acuity and queratometric astigmatism were measured at 3 and 6 months.ResultsAverage surgical time for the fibrin glue group was 36.1minutes vs. 55.1minutes for the control group (P=<.0001). Average queratometric astigmatism at 3m was −3.69D for the fibrin glue group vs. −4.75D for the standard keratoplasty group (P=.245) and −2.88D vs. −3.44D at 6m (P=.246). Average best corrected visual acuity was LogMAR 0.37 for the fibrin glue group vs. LogMAR 0.39 at 3m (P=.822) and LogMAR 0.20 vs. LogMAR 0.25 at 6m (P=.334). There were no complications related to the surgical procedure in any group.ConclusionsPKP with 8 sutures and fibrin glue seems to be a safe technique which requires less surgical time and allows for a faster visual recovery compared to the standard technique.
