00 diopters spherical equivalent
at the spectacle plane) can be corrected to reduce dependence on glasses or contact lenses.
The FDA approved expansion of ATCI's ongoing trials includes subjects with higher degrees (up to -10 Diopters) of myopia and up to -6 Diopters of astigmatism, for a maximum spherical equivalent
correction of -10 Diopters.
The ALLEGRETTO WAVE, manufactured by WaveLight Laser Technologie, AG, was the first refractive laser to receive concurrent approvals for the treatment of myopia up to -12 diopters with astigmatism of up to -6 diopters and hyperopia up to +6 diopters with astigmatism of up to +5 diopters, not exceeding a mean spherical equivalent
of +6 diopters.
Cumulative change in spherical equivalent
refraction (myopic shift) after 3 years was significantly less in the intervention group than in the control group.
00D or less of myopic spherical equivalent
with or without astigmatism, and high myopia, which is >7.
for the correction of myopic astigmatism in adults 21-45 years with spherical equivalent
ranging from -3.
All the children had myopia with a spherical equivalent
of more than -0.
00 diopters (D) of spherical equivalent
of myopia or myopia with astigmatism, with up to -7.
In all cases, the total diameter is larger than the spherical equivalent
design to help stability on the eye.
The approval for hyperopia was granted for up to +6 diopters and with astigmatism of up to +5 diopters, not exceeding a mean spherical equivalent
of +6 diopters.
0 D at the spectacle plane, with a maximum manifest refraction spherical equivalent
(MRSE) of +6.
Alio found better results in patients with mild keratoconus (less than 53 dioptres) and relatively low spherical equivalent
whereas with advanced keratoconus and high spherical equivalent
, poorer results (:an be anticipated.
