Opticalc Toric Contact Lens Calculator will help you improve your fitting skills when prescribing soft contact lenses. Given a patient's refraction and vertex distance, it will tell you their ocular refraction corrected for vertex distance. It then provides a recommended spherical contact lens power ...
This is a thick lens formula based on Gaussian optics principles; it considers the anterior and posterior corneal curvatures, central corneal thickness, as well as the geometry of the intraocular lens (IOL). The formula modifies the axial length measured by optical biometry, calculates the total ...
(K), central corneal thickness (CCT), anterior chamber depth (ACD), lens thickness (LT), horizontal white-to-white (WTW) corneal diameter, and axial length (AL). The total keratometry (TK), integrated in the IOLMaster 700, is a new keratometry value combining telecentric three-zone ...
An excellent choice for all IOL types in any anatomy Lenstar provides highly accurate laser optic measurements for every section of the eye −from the cornea to the retina− and is the first optical biometer on the market that can measure the thickness of the crystalline lens. With its ...
Over the past years, photonic metasurfaces have demonstrated their remarkable and diverse capabilities in advanced control over light propagation. Here, we demonstrate that these artificial films of deeply subwavelength thickness also offer new unparalle
