5 D were categorized as emmetropia
, with SER [greater than or equal to] +0.
The purpose of this study was to measure the intraocular distances (using A-scan ultrasound biometry) and corneal curvature (using keratometry) of feline eye and to use these data to predict appropriate posterior chamber IOL strength to achieve emmetropia
after lens removal.

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.
The co-ordinated growth of the eye to reach emmetropia
is dependent on clear visual input.
However, I hypothesize that the eye is incapable of such detection and will use a trial and error system to reach emmetropia
, Biometry, Keratometry, IOL specific constants.
The operational definitions of emmetropia
, myopia and hypermetropia are not uniform across studies.
Prevalence of cataract type in relation to axial length in subjects with high myopia and emmetropia
in an Indian population.
3) Toric IOLs can be used to achieve emmetropia
or myopia (normally in targeted monovision or mini-monovision) for patients who have 0.
All cases of emmetropia
, myopia, hypermetropia, astigmatism between 20-30 years.
These monofocal IOLs are routinely implanted during NHS cataract surgery with the refractive aim of emmetropia
During the early years in life, the eye grows in such a manner that the refractive state tends towards emmetropia
A two-month-old girl was born with a congenital cataract in the right eye and following lens extraction she is now aphakic with emmetropia
in the fellow eye.
Myopia and Emmetropia
appeared in relatively equal amounts (15% and 14% respectively).
