Abstract

Background: The non-contact optical methods are preferable in Intra-ocular Lens (IOL) power calculation as they have higher resolution, better patient tolerance and greater acceptability. Aim: to compare between LENSTAR LS900 and IOL Master V4 in IOL power calculation. Material and Methods: This prospective comparative study included 60 eyes of 40 cataract patients. Patients with immature cataract of any age and both genders were included while those with dense cataract, media opacities, previous ocular diseases or surgeries or intraoperative complications were excluded. Patients were assessed by a complete comprehensive ophthalmic evaluation. Each patient was evaluated twice, one by the IOL Master and the other by the LENSTAR LS900. Outcome measures were axial length (AL), vertical keratometric dioptric power (K1), horizontal keratometric dioptric power (K2), and IOL power measurements. Results: The mean age of the patients was 67.08 ± 5.34 years. Thirty-five patients were males and 25 were females. The IOL master and LENSTAR were similar (p>0.05) in terms of the AL (24.82 ± 2.21and 24.80 ± 2.20), K1 (43.13 ± 1.66 and 43.14 ± 1.68), K2 (44.14 ± 1.56 and 44.27 ± 1.52) and IOL power (16.86 ± 5.24 and 16.84 ± 5.26). The target refraction on IOL master was -0.01 ± 0.06 compared with 0.04 ± 0.10 on LenStar. The actual refraction was 0.00 ± 0.33. There were non-significant differences between target and actual refractions on both devices (p>0.05). Conclusion: Both the optical biometers, IOL Master and LENSTAR provide similarly precise biometry and IOL power calculation in cataract patients.
