PalmScan x IOL Master

Presented by: Ray T. Oyakawa, M.D. Sharper Vision Centers A MEDICAL GROUP Comparison of PalmScan and IOL Master axial lengths measurements No financial interests ASCRS Chicago 2008

Study Design Prospective study for axial length measurement comparison between PalmScan & IOL Master. 74 consecutive eyes of patients for presbyopia correcting IOLs between January 19, 2007 & October 17, 2007. Three eyes were eliminated-could not be measured with IOL Master V 3.02 software & 5.02 software. One eye was successfully measured with V. 5.02 when it could not be measured with V 3.02. 47 eyes were done with V 3.02 software and 24 eyes with V 5.02 software.

Technique IOL Master measurements were taken by two experienced technicians. All immersion measurements were taken by the author with the patient in a supine position using the Micro Medical PalmScan handheld A-scan.

Results Range of axial lengths 21.38 mm to 28.91 mm-IOL Master Average axial length 24.53 mm –standard deviation 1.82 mm-IOL Master Average difference in axial length between the PalmScan and IOL Master 0.022 mm with standard deviation of 0.10 mm and R coef. of 0.998 4.1 % of eyes could not be measured with the IOL Master version 5.02 software.

Range of axial lengths 21.38 mm to 28.91 mm-IOL Master

Average axial length 24.53 mm –standard deviation 1.82 mm-IOL Master

Average difference in axial length between the PalmScan and IOL Master

0.022 mm with standard deviation of 0.10 mm and R coef. of 0.998

4.1 % of eyes could not be measured with the IOL Master version 5.02 software.

Results Correlation Coefficient = 0.998

Correlation Coefficient = 0.998

Conclusion Axial length measurements by the PalmScan immersion ultrasound is comparable to the IOL Master and can be used when the IOL Master can not get an axial length measurement. Immersion was needed in 4.1% (3/74). Immersion units are still need even if you have an IOL Master.
