Abstract

MéTODO PARA ESTABILIZAR UMA QUANTIDADE DE ENERGIA DE LASER LIBERADA A UM ALVO POR UM DISPOSITIVO GERADOR DE LASER, E, MéTODO E SISTEMA PARA EXECUTAR UM PROCEDIMENTO DE CIRURGIA DE OLHOA A LASER Sistemas e métodos provêem estabilizar a quantidade de energia de laser liberada a um alvo de um dispositivo de laser. Geralmente, energia de laser liberada é medida através de múltiplos pulsos de laser ou com o passar do tempo no caso de um laser de onda constante. Uma diminuição é então calculada na energia liberada, a diminuição sendo causada por acumulação de uma ou mais substâncias, tal como ozónio, ao longo do trajeto de liberação de feixe de laser devido à passagem do feixe de laser ao longo do trajeto. Usando esta diminuição calculada, um dispositivo de laser pode ser ajustado para compensar a diminuição em energia liberada devido às substancias acumuladas, assim estabilizando a quantidade de energia liberada ao alvo.
