Lenstar LS 900 versus Pentacam-AXL: analysis of refractive outcomes and predicted refraction

Prospective study of toric IOL outcomes based on the Lenstar LS 900® dual zone automated keratometer

BACKGROUND To establish clinical expectations when using the Lenstar LS 900® dual-zone automated keratometer for surgery planning of toric intraocular lenses. METHODS Fifty eyes were measured with the Lenstar LS 900® dual-zone automated keratometer . Surgical planning was performed with the data from this device and the known surgically induced astigmatism of the surgeon. Post-operative refra...

Comparison of pupil diameter measurement with Lenstar LS 900 and OPD Scan II. Not interchangeable devices.

D pupil measurement is of great concern in corneal refractive surgery, as well as when phakic or multifocal intraocular lens (IOL) implantation is planned.1,2 Pupil size may influence the choice of ablation zone in refractive surgery and IOL design in cataract surgery, and it should be measured accurately so as not to end up with unfavorable postoperative outcomes, such as halos, glare, or poor...

Axial Length Measurement Failure Rates with the IOLMaster and Lenstar LS 900 in Eyes with Cataract

PURPOSE To evaluate axial length (AL) measurement failure rate with the IOLMaster (Carl Zeiss AG, Germany) and Lenstar LS 900 (Haag-Streit AG, Switzerland) in eyes with cataract. METHODS Two hundred and ninety-six eyes of 170 patients with cataract were enrolled. Cataract type and severity were graded using the Lens Opacities Classification System III (LOCS III) and AL measurements were attem...

Ciliary muscle morphology in emmetropia and ocular biometric correlates

Purpose: Recent studies have documented a link between axial myopia and ciliary muscle morphology; yet, the variation in biometric characteristics of the emmetropic ciliary muscle are not fully known. Ciliary muscle morphology, including symmetry, was investigated between both eyes of emmetropic participants and correlated to ocular biometric parameters. Methods: Anterior segment optical cohere...
