Formulae to calculate the emmetropic IOL from the aphakic SE
| Axial length | Formula for emmetropic IOL | |
|---|---|---|
| LiHue | No distinction | 8.67+0.95×SEaph |
| LiHue/AL | <25.5 mm | 55.16+0.454×SEaph–1.698×AL |
| >25.5 mm | 54.886+0.454×SEaph–1.698×AL |
AL, axial length; IOL, intraocular lens; SEaph, spherical equivalent during aphakia with ophthalmic viscosurgical device.
