[A study on axis length measurement of high myopia with cataract].
OBJECTIVE
To study the accuracy of axis length measurement on high myopia with cataract.


METHODS
A/B scan ultrasonography and IOL-master were used to measure the ocular axial length in 168 high myopic eyes with cataract of 103 cases. B-scan ultrasonography was used to examine posterior scleral staphyloma. Refractive results were recorded during the follow-up after operation to evaluate the accuracy of measurement.


RESULTS
The rate of posterior scleral staphyloma was 76.19%. The average postoperative error of refractive of all eyes was between -1.0 D and +1.0 D.


CONCLUSIONS
Accurate data of axis length can be obtained by combining results of A-scan, B-scan ultrasonography and IOL-master for high myopia with cataract, especially for patients with posterior scleral staphyloma.
