Abstract Details

Purpose:

To compare the results of ocular biometry between a new device, the Aladdin, and the IOL Master 500.

Setting:

2 private ophthalmic ambulatory care centres

Methods:

Ocular biometry data was collected on 98 eyes prior to cataract surgery by the same skilled technician on the Aladdin and the IOL Master 500. The number of eyes unable to be captured by either device was documented as well as speed of usage. An IOL power calculation was performed using the standard IOL Master 500 and Aladdin data (which uses Sim K for keratometry from its inbuilt topographer).

Results:

The mean difference between the Aladdin and IOL Master 500 was 0.005mm for axial length, -0.02D for keratometry, -0.007mm for anterior chamber depth and 0.04D for IOL power calculation. None of these were statistically significant. 5 of the 98 eyes were unable to be measured by the IOL Master 500 but all eyes were measured by the Aladddin.

Conclusions:

The Aladdin gives equivalent results to the current gold standard machine the IOL Master 500 but in addition gives placid based topography. In this cohort of eyes, the Aladdin managed to measure significantly more eyes than the IOL Master 500.
