The focal length (f) of a converging lens is considered positive and that of a diverging lens is considered negative. Thus, the power of a converging lens is positive and that of the diverging lens is negative. Lens Formula in Terms of Power (Image will be uploaded soon) Fig.1 shows tw...

To develop a novel machine learning-based intraocular lens (IOL) power calculation formula for highly myopic eyes. A total of 1828 eyes (from 1828 highly myopic patients) undergoing cataract surgery in our hospital were used as the internal dataset, and
Under the lens of maximum empathy for people using Dear ImGui in other languages bindings, some auto-generated, some not, some with static typing, some not etc.. (cc. @mellinoe @sonoro1234) And then TRY those changes in your codebase so you can help us validate the reasoning and provid...
Objective To compare the accuracy of a new intraocular lens (IOL) power formula (Kane formula) with existing formulas using IOLMaster, predominantly model 3, biometry (measures variables axial length, keratometry and anterior chamber depth) and optimised lens constants. To compare the accuracy of th...
I decided to upgrade my desktop motherboard to an AMD Ryzen 6 core (12 thread) and 16gb of DDR4 is more than enough horsepower to run everything and anything, and allows PowerSDR to run at 30fps and the analog meter movement to run at 40msec with 3 - 6% cpu. ...
For the pre-operative calculation of the power of an intraocular lens, three input parameters are needed: the axial length of the eye (AL), the refractive power of the cornea, and t
An ophthalmic aberration corrected toric lens which is derived from a basic toric lens, said basic lens having on a block of refringent material a spherical refracting surface and a toric refracting surface, said basic lens further having first and second main meridian planes at right angles to...
A camera system having a power zoom lens and an automatic focusing device, comprising a zoom motor for zooming the power zoom lens, a focal length detecting device for detecting a focal length of the
