E.5 End points |
E.5.1 | Primary end point(s) |
The evaluation of feasibility and safety of the study will be made once the patient has received treatment at 3-month implant and follow-up year. We define that the process is safe when development and monitoring of the trial has not produced any adverse event that may be related to the proposed therapy in the trial. All clinical adverse events during follow-up will be collected at the same time that the clinical evaluation. The main objective will be assessed the cumulative incidence of adverse effects attributed to therapy in the study. |
De factibilidad y seguridad del estudio se realizará una vez el paciente haya recibido el tratamiento, al 3º mes del implante y al año de seguimiento. Se define que el proceso es seguro cuando durante el desarrollo y seguimiento del ensayo no se ha producido ningún acontecimiento adverso que se pueda relacionar con la terapia propuesta en el ensayo. Todos los acontecimientos adversos clínicos serán recogidos durante el seguimiento en los mismos tiempos que la evaluación clínica. Se evaluará como objetivo principal la incidencia acumulada de efectos adversos atribuidos a la terapia en el estudio. |

at the 3-month implant and follow-up year |
al 3º mes del implante y al año de seguimiento |
|
E.5.2 | Secondary end point(s) |
As part of assessing the status of patients quality of life a SF-36 test will be filled out and the nonexistence of long-term adverse effects will be recorded as measured by the non-recurrence of pain, conjunctivalization, ulcers and corneal epithelial neovascularization, after 1 year from the implant. Both studies will be conducted by clinical investigators of the trial, if there is no agreement in the diagnosis an expert ophthalmologist from outside of the study will be consulted. |
Como parte de la evaluación del estado de la calidad de vida de los pacientes se rellenará un test SF-36 y se registrará la no existencia de efectos adversos a largo plazo medida por la no recurrencia de dolor, conjuntivalización, úlceras epiteliales corneales y neovascularización, pasado 1 año desde el implante. Ambos estudios serán realizados por los investigadores clínicos del ensayo, en caso de no existir acuerdo en el diagnóstico se recurrirá a un oftalmólogo experto ajeno al estudio. |
