Purpose

To compare measurements agreement between Pentacam based on Scheimpflug principle and EyeStar based on swept-source optical coherence tomography

Setting

Private hospital, Ishwar Eye Centre, Haryana, India

Methods

204 eyes of 102 subjects were taken as sample size. CCT, SIM K1,K2, Ant Q, Post Q, SIM PK1,PK2 measurements were performed using pentacam and then with Eyestar  devices. Analysis used SPSS software, paired t test and Bland Altman plots.

Results

Mean±SD of CCT-not significantly different (p value=0.518). Mean ± SD of SIM K1 in Pentacam 43±1.83, Eyestar 42.95±1.77, no significant difference (p value=.397). Mean ± SD of SIM K2 in Pentacam 44.12±1.89 ,significantly higher compared to measured by Eyestar (43.98±1.8)(p value=0.007).Mean ± SD of AntQ in Pentacam 0.31±0.18 and Eyestar  0.32±0.15, no significant difference (p value=0.773). Mean ± SD of PostQ in Pentacam 0.34±0.23, significantly higher as compared to Eyestar (0.29 ± 0.19)(p value<.0001).Mean ± SD of SIM PK in Pentacam 6.11±0.34, significantly higher compared to Eyestar (6.03±0.27)(p value<.0001). Mean±SD of SIM PK2 in Pentacam  6.41±0.34 which was significantly higher as compared to Eyestar (6.26±0.33) (p value <.0001).

Conclusions

Pentacam and Eyestar can be used interchangeably for measurement of  CCT, SIM,K1,AntQ but not for SIM K2 and PostQ.
