ABSTRACT
INTRODUCTION:
A-scan ultrasound is currently the most widely used technique for axial length measurement; however, this method is not optimal in silicone-oil filled eyes. Two techniques that may be more accurate for axial length measurements in these eyes are intraoperative measurement of axial length after silicone oil removal or measurement by Laser interferometry using the IOL Master. The purpose of this study is to evaluate and compare the accuracy of both intraoperative biometry and partial coherence interferometry in silicone oil-filled eyes. PATIENT ANDMETHODS:
Axial length measurement of 22 cataractous silicone-filled eyes of 21 patients using both IOL Master Biometry and intraoperative A-scan biometry was performed. IOL power was then computed using the SRK-T formula. Accuracy of intraoperative biometry and partial coherence interferometry was evaluated by determining the mean actual postoperative refractive error.RESULTS:
Comparing the predictability of intraoperative A-scan biometry and IOL Master Biometry, the two techniques showed small predictive postoperative refractive errors without a statistically significant difference in the predictive errors of the two techniques.CONCLUSION:
Both intraoperative biometry by A-scan ultrasonography and partial coherence interferometer by IOL Master proved to have good equal predictability for absolute postoperative refractive error in cataract surgery for eyes filled with silicone oil.
