Biometria ultrassônica no cálculo do po<strong>de</strong>r dióptrico <strong>de</strong> lentes intraoculares: estudo comparativo dos métodos...215CONCLUSÃOOs dados <strong>de</strong>ste estudo evi<strong>de</strong>nciam precisão ereprodutibilida<strong>de</strong> dos resultados, e permitem concluir queo método <strong>de</strong> imersão é mais preciso e apresenta maiorconfiabilida<strong>de</strong>, po<strong>de</strong>ndo evitar erros no cálculo do po<strong>de</strong>rdióptrico da LIO e consequente insatisfação visual dopaciente no pós-operatório da cirurgia <strong>de</strong> catarata.Como se verificou diferenças significativas nosdois métodos, sugere-se a<strong>de</strong>quação das diversas fórmulas<strong>de</strong> cálculo <strong>de</strong> LIO para a técnica <strong>de</strong> imersão, já queas fórmulas usadas atualmente foram baseadas principalmenteem dados ecobiométricos <strong>de</strong> contato.ABSTRACTPurpose: To compare the ultrasound biometrymeasurements between immersion and contact techniques.Methods: The biometry was ma<strong>de</strong> in 60 eyes by the sameexaminer, using the contact and immersion techniques ineach eye. Results: The lower mean axial length (23,16 mm)was found in the contact technique, and the greater (23,29)was found in the immersion technique, using the same probe.The lower mean standard <strong>de</strong>viation between recurrentmeasures in the same eye was found in the immersiontechnique, and the greater in the contact procedure, andwas found statistically significant (p
