Abstract Details

Purpose:

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)

Setting:

Mumbai Eye Care Cornea and LASIK centre

Methods:

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

Results:

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)

Conclusions:

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

Financial Disclosure:

NONE
