Comparison of Hoffer Q and Haigis Formulae for Intraocular Lens Power Calculation According to the Anterior Chamber Depth in Short Eyes

Meta‐analysis of accuracy of intraocular lens power calculation formulas in short eyes

“…In total, there are 1161 eyes are enrolled from the 10 included studies (characteristics shown in Table ) . The sample size ranged from 15–608 eyes.…”

“…In total, there are 1161 eyes are enrolled from the 10 included studies (characteristics shown in Table 1). [12][13][14][15]18,19,[24][25][26][27] The sample size ranged from 15-608 eyes. All of the trials utilized IOL master for AL measurement.…”

Comparison of SRK/T and Haigis formulas for predicting corneal astigmatism correction with toric intraocular lenses

“…Thus, the accuracy of the IOL formulas in predicting corneal astigmatism correction by toric IOLs could vary, just as the accuracy of predicting refractive outcome varies among the IOL formulas. 19,22 The SRK/T formula overestimates the ELP when the K value is steep and underestimates it when K is flat, whereas the Haigis formula does not. 19 In fact in this study, the Haigis formula was more accurate than the SRK/T formula in predicting both refractive outcome and corneal astigmatism correction by toric IOLs.…”

Mensurações do bulbo ocular e cálculo do poder dióptrico da lente intraocular em miniporcos

“…Sabe-se que, em olhos curtos e extremamente curtos, essa proporção nem sempre é obedecida, o que aumenta a chance de erro refrativo final no cálculo (Holladay et al, 1995;Carifi et al, 2015), remetendo, portanto, aos olhos dos miniporcos. As fórmulas mais recentes minimizam esse erro devido às mensurações adicionais (Narvaéz et al, 2006;Eom et al, 2013a).…”

“…A correção dessa afacia é feita utilizando-se o implante de lentes intraoculares (LIO) sintéticas, cujo emprego é consagrado na medicina (Day et al, 2012;Eom et al, 2013a). Na oftalmologia veterinária, há crescente preocupação em promover uma visão mais próxima possível à emetropia, objetivando melhora na qualidade de vida dos animais (Monteiro e Allemann, 2001;Harrington et al, 2013).…”
