MIRANDA HERNANDEZ, Iramis et al. Evaluation of Lenstar partial coherente optical interferometry device in the ocular biometry. Rev Cubana Oftalmol [online]. 2010, vol.23, suppl.2, pp. 665-677. ISSN 0864-2176.

OBJECTIVES: To compare and to evaluate the ocular biometry taken by a new optical partial coherence interferometry device (Lenstar),the low coherence optical interferometry equipment (ILO Master) and the topographic systems Pentacam y Galilei. METHODS: A descriptive cross-sectional study was conducted in 120 eyes from 60 patients. For the IOL calculation, the necessary measurements were taken with the new optical biometer Lenstar LS 900 (Haig Streit AG) and with the IOL Master V5 (Carl Zeiss Meditec AG). The results were evaluated using the linear regression analysis and Pearson´s correlation. The measures were then compared to those taken by topographic devices Galilei and Pentacam. RESULTS: There existed high correlation in biometric measurements of axial length, keratometry and anterior chamber depth between the Lenstar and the IOL Master. Good correlation was also found for the Keratometry and anterior chamber depth between the Lenstar and the topographs Pentacam and Galilei. CONCLUSION: The new biometer LENSTAR provided results that correlated very well with those of the IOL Master, Pentacam and Galilei systems. Lenstar is a precise device offering additional features that will be helpful for any cataract or refractive surgery.
