Abstract Details

Purpose:

The aim of this study is to evaluate the agreement and interchangeability between IOL Master and pentacam in phakic IOL calculations.

Setting:

Sohag University Hospital Egypt

Methods:

A prospective study involving the measurement of the 3 anterior segment parameters: Anterior chamber depth (ACD), white to white line (WTW) and average anterior corneal curvature (K- reading) on 108 healthy eyes of 56 consecutive patients. Inter-device agreement and interchangeability in phakic IOL calculations was evaluated

Results:

Pentacam measured a significantly longer ACD measurements (3.54± 0.35 mm) than the IOL Master (3.40 ± 0.37 mm) (P<0.0001), on the other hand, it measured a significantly shorter WTW line measurements (11.61±0.44mm) than the IOL master (11.66±0.42 mm) (P=0.016). No difference was found regarding the average K readings. For biometry and phakic IOL power calculation; there was no clinically significant difference between both devices but for phakic IOL diameter calculation the difference was clinically significant.

Conclusions:

There is a good agreement in ACD and K-readings between pentacam and IOL master making them interchangeable in biometry and phakic intraocular lens power calculation but they are not interchangeable regarding WTW line measurement, the difference will affect the phakic IOL diameter which would affect lens safety.
