Abstract Details

Purpose:

Purpose of this study was to assess the capability of swept-source optical coherence tomography technology to decrease the proportion of eyes that have insufficient signal-to-noise ratio in optical biometry

Setting:

Hanusch Hospital, Vienna, Austria

Methods:

In this prospective study, consecutive cataract patients coming for biometry that were unsuccessfully measured with partial coherence interferometry technology (IOLMaster 500, Zeiss Meditec AG, Jena, Germany) were re-measured using swept-source optical coherence tomography technology (IOLMaster 700, CZM).

Results:

Altogether, 1226 eyes of 613 patients were screened for this study. Of these, 65 patients (52 single eyes and 13 patients, where both eyes could not be measured successfully). Of these unsuccessful scans 92% were able to be measured with swept-source optical coherence tomography technology (p<0.001). The reasons for unsuccessful measurements will be presented at the meeting.

Conclusions:

Swept-source optical coherence tomography technology was shown to be superior to conventional partial coherence interferometry in terms of successful axial eye length measurements.
