Due to the ambiguity of nominal (magnifier power/4) and trade ((magnifier power/4) +1) magnification values and the fact that they can only be truly met under very specific and unrealistic conditions, often the best way is to determine the dioptric power of the magnifier as a starting point only and work from there.
The I-S index, developed by Rabinowitz and McDonnell (14), determines the dioptric power difference between the inferior and superior corneal zones.
Accommodation is the process whereby the crystalline lens changes its dioptric power to focus precisely and maintain the object of interest at the high-resolution fovea [1].
Aberrations vary depending on the dioptric power optical diameter material design and RI of the IOLs.
They allow calculations of intraocular lens dioptric power to be employed in eyes of animals that have undergone cataract surgery to achieve emmetropia (SAMPAIO et al.
15) If we want to correct a myopia, which has the focus in front of the macula, we need to subtract dioptric power from the cornea, moving the focus posteriorly to the retina.
1987) that observers with reduced acuity are better able to resist optical blur, our older observers required lenses of somewhat greater dioptric power to degrade acuity to 20/30 and 20/40 levels.
The structure of an IOL consists of a central optic housing the dioptric power of the implant with projections called haptics spanning out to provide stability once implanted (see Figure J).
1] = n/f, which is the dioptric power of the eye when an object is viewed at infinity
The cornea is the first major refractive surface of the eye and is responsible for over two thirds of its overall dioptric power.
