Abstract Details


To compare the emmetropic IOL power calculation after myopic LASIK using OCT (Optovue), optical biometry (AL – Scan, Nidek- Schammas PL formula) & ray tracing (Sirius, CSO)


Mumbai Eye Care Cornea and LASIK centre


30 post myopic LASIK eyes were evaluated for biometry. IOL power nearest to emmetropia was noted (A constant 118.9) using above machines & compared


Mean emmetropic IOL powers using OCT, AL- scan & Sirius were 22.48D, 22.7D & 21.43. (OCT vs Al – scan – Not significant, OCT vs Sirius and AL- scan vs Sirius p < 0.005)


OCT based IOL power calculation correlated well with optical biometry, but that using ray tracing was significantly different and more hyperopic
