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

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.
