Comparison Of Refractive Outcome For Multifocal Intraocular Lens Implantation As Measured By Two Devices: Lenstar Vs. Galilei

To evaluate the accuracy of multifocal intraocular lens (MIOL) power biometry calculation of two devices: Lenstar LS900 and Galilei

European Medical Center

Medical records of 72 eyes of 36 patients who underwent uneventful cataract surgery with MIOL (Acrysof IQ Panoptix) implantation were retrospectively reviewed. Biometry measurements for each patients were performed by two devices: Lenstar LS900 and Galilei. Paired comparison were performed for axial length (AL), mean Keratometry (Km) and anterior chamber depth (ACD). Subjective refractive outcomes were compared for both devices following cataract surgery.

The AL measured by Lenstar LS900 was longer than that measured by Galilei (23.28±0.28 and 23.24±0.27, p<0.001).  The Km measured using Lenstar LS900 was lower in comparison to Galilei (44.14±1.4 and 44.23±1.2, p=0.002). The ACD measured by Lenstar LS900 was deeper than that measured by Galilei (3.15±0.4 and 3.08±0.38, p<0.001).  The predicted spherical equivalent as measured before the surgery was for Lenstar LS900 -0.22±0.09  and  for Galilei 0.20±0.06, (p=0.661).   Postoperatively the patient subjective refraction did not differ significantly to prediction for both devices: Lenstar LS900 and Galilei ( p=0.128 and p=0.09).

The Lenstar LS900 demonstrated a trend towards superior accuracy rate of biometric measurements, but was not significantly so in  comparison to Gallilei. Ocular biometry using these two devices showed high agreement and accuracy for MIOL calculation.
