Accuracy of Scheimpflug corneal power measurements for intraocular lens power calculation

Abstract: Corneal power measurements with the Pentacam Scheimpflug system should be used in IOL power calculation formulas with caution because the accuracy is good but is not as high as with standard measurement methods.

“…This type of astigmatism was measured with Pentacam in our study, with IK4 in the study by Harvey et al (10), and with IOL Master in the study by Huynh et al (23). As studies demonstrated, keratometry readings measured with these devices are not interchangeable (24)(25)(26)(27) and this could be the reason for different results.…”

“…Therefore, prior to using Pentacam values in these cases, they should be correlated and corrected. This fact might explain why Savini et al and Shammas et al did not find Scheimpflug system the most reliable method to calculate IOL power (18)(19) . The results of FK and SK analysis also suggest that the systems are not interchangeable, since the comparison between EyeSys and Pentacam values showed statistically significant differences concerning these parameters, corroborating with similar studies, which tried to analyze the interchangeability of both instruments (20)(21) .…”

“…O Orbscan II utiliza fendas de luz que varrem a córnea (20 da direita para a esquerda e outras 20 na direção oposta) para a análise das superfícies anterior e posterior da córnea, combinadas à projeção dos discos de Plácido, totalizando 9.600 pontos analizáveis (3)(4) . Ainda são poucos os artigos, na literatura, que comparam a precisão destes dois equipamentos no cálculo do poder da LIO, sendo que, por vezes, as conclusões são discordantes (1)(2)(3) . A mensuração do CA pela ICOp apresenta maior precisão que a obtida a partir da biometria de contato, mas parece ter precisão equiparável àquela da biometria de imersão (1) .…”

A mensuração do CA pela ICOp apresenta maior precisão que a obtida a partir da biometria de contato, mas parece ter precisão equiparável àquela da biometria de imersão (1) . O cálculo biométrico do poder da LIO depende, dentre outros fatores, da ceratometria central da superfí-cie anterior da córnea.…”
