Intraocular lens power calculation by measuring axial length with partial optical coherence and ultrasonic biometry Cálculo da dioptria da lente intraocular medindo o comprimento axial através de interferometria de coerência parcial ou biometria ultrassônica
Objetivo: Comparar os resultados refracionais obtidos em pacientes submetidos à cirurgia de catarata com cálculo da lente intraocular realizado por meio de biometria ultrassônica de imersão (US) ou por interferometria de coerência parcial (ICP). Métodos: Série de casos comparativa, prospectiva. Os pacientes submetidos à cirurgia de catarata foram aleatoriamente divididos em dois grupos em relaç...
متن کاملPart A: Biometry and Intraocular Lens Power Calculation
Formulas For Intraocular lens Power calculatIon Modern cataract surgery replaces the natural lens of the eye with an intraocular lens (IOL). After surgery, the optical system of the eye will consist of two major refractive elements, the cornea and the newly inserted IOL. This two-lens system is at the basis of IOL power calculation. To facilitate calculations, both the cornea and the IOL are co...
متن کاملBiometry and intraocular lens power calculation results with a new optical biometry device: comparison with the gold standard.
PURPOSE To evaluate the agreement in axial length (AL), keratometry (K), anterior chamber depth (ACD) measurements; intraocular lens (IOL) power calculations; and predictability using a new partial coherence interferometry (PCI) optical biometer (AL-Scan) and a reference (gold standard) PCI optical biometer (IOLMaster 500). SETTING Service d'Ophtalmologie, Hopital Bicêtre, APHP Université, Pa...
متن کاملAccuracy of optical biometry combined with Placido disc corneal topography for intraocular lens power calculation
PURPOSE To investigate the accuracy of a new optical biometer for intraocular lens (IOL) power calculation in eyes undergoing cataract surgery. METHODS Consecutive eyes of patients undergoing cataract surgery with the same IOL model were enrolled in a prospective cohort study. Axial length (AL) and corneal power were measured with an optical biometer based on optical low-coherence interferome...
