Abstract Details

Purpose:

To compare the accuracy of pentacam keratograph 4 IOL Master and manualcaliper in measured corneal horizontal diameter and refer the clinical references.

Setting:

Wuhan Aier Eye Hospital,Wuhan,China.

Methods:

The corneal horizontal diameter was measured in 160 eyes of 80 patients using pentacam、newly developed corneal topographer4、IOL Master and manualcaliper,each measurement was repeated three times ,the results were compared.

Results:

The corneal horizontal diameter measured by pentacam、newly developed corneal topographer,and manualcaliper wer(11.58 ±0.29mm, 11.48 ±0.37)mm,(11.52 ±0.36)mm,there were no significant difference between the three measurement (all P>0.05). the corneal horizontal diameter measured by IOL Master was(11.85 ±0.33)mm, there were significant difference between the IOL Master and the other three measurements(all P<0.05).

Conclusions:

Pentacam,newly developed corneal topographer and manualcaliper can be interchanged for corneal horizontal diameter.But the corneal horizontal diameter measured by IOL Master is longer.
