while that in group 2 was 0.55 +- 0.36 diopters
: Unit of measure that shows the refractive power of a lens or prism.
Phase III Intacs patients and 46 LASIK patients, all treated for -1.0 to -4.0 diopters
of myopia at Hunkeler Vision Centers in Kansas City.
Features: 28-80mm motorised zoom lens, diopter
adjustment, infra red auto focus, LCD panel which indicates red eye reduction, fill-in flash, slow shutter sync, flash off, self timer and landscape mode facilities, automatic rewind, mid-roll rewind facility, auto battery shut-off, low battery indicator, tripod socket, carry case.
We also reported a much higher anisometropia incidence than him  (61.7% of RE versus 3%) as he included only eyes with >4.0 diopter
interocular difference, while we included cases with >1.0 diopter
interocular difference which is more appropriate for scientific and statistical purposes.
A 90 diopter
Volk[R] (Volk Optical, Inc., Mentor, OH, USA) noncontact double aspheric lens was attached to the smartphone with clear tape (Figure 1).
The mean refractive spherical equivalent (SE) before surgery was -3.401.73 Diopters
(range-0.63 to -9.25 Diopter
) and mean LogMAR BCVA before surgery was 0.0270.09 (range of 0.00to0.46).
ACTION TYPE: Gas-piston, rotary holt, semi-auto, CALIBER: 5.56 NATO and .223 Rein, BARREL LENGTH: 16", OVERALL LENGTH: 37", LENGTH FOLDED: 27", WEIGHT: 7.8 pounds, FINISH: Matte black, SIGHTS: Emergency folding diopter
, 4-position rotary diopter
; square front post, STOCK: Polymer, side-folding, PRICE: $1,599
Close focus is 4.9' and the diopter
can be locked to prevent it from acciden- c tally being changed.
Riflescopes feature 30mm main tubes, magnification factor of 6x, Fast Diopter
Adjustment, eye relief of 4" to 4.5" and fully multicoated and index-matched lenses finished with StonnCoat.
At four years after surgery, 44 of the eyes (79 percent) were within 0.5 diopter
(unit of measuring lens power) of the targeted correction and 52 (93 percent) were within one diopter
To avoid problems, I suggest you aim your camera at a blank wall, use the "distance" portion of your eyeglass prescription, and keep your eye relaxed as you tweak the camera's diopter
adjustment until the viewfinder grid and reference marks appear razor sharp.
