There's diopter adjustment for those with vision deficits and binocular-style focusing.

There's also a built-in diopter beneath the rear edge, which means it won't get spun around in your bag.

Zou, for example, is near-sighted, so Iris would recognize her and immediately set the diopter so she can see clearly.

Depending on the diopter of a lens, eyes have to rotate through fewer or more degrees to correct for refractive change.

The difference between PMMA and cornea ablation rates should be considered when using PMMA to test ablated diopter and smoothness for photorefractive surgery.

Myopia -0.5 diopter or less in either eye or hyperopia 2 diopters or greater was observed in less than 3% of children.

The average age of the patients was 50 years and average refractive error was -4.25 diopters (D).

Results: Overall, the patients showed an increase of 9.14 prism diopters (PD) during a mean preoperative follow-up of 4.2 months.

Attempted corrections ranged from 2.25 to 14.5 diopters of myopia, giving theoretical ablation depths of 182 to 332 microm below the corneal surface.

Methods: Color stereo optic disc photographs of 562 patients with POAG and a myopic refractive error of less than -8 diopters were morphometrically examined.

Conclusions: Corneal endothelial cell density and morphology were unchanged 2 and 12 weeks after LASIK for the correction of up to 14.5 diopters of myopia.

A, 46-year-old Indian male, known hypertensive presented with left esotropia of 25 prism diopters (PD) after head injury in a roadside accident 9 months back.
