Ametropia was found in 56 (21.4%) children, while 206 (78.6%) had no
refractive error. Out of children with ametropia, 20 (35.7%) had myopia, 24 (42.8%) had astigmatism and 12 (21.5%) had hypermetropia.
Objective
refractive error was measured with an autorefractometer (Canon RK-F1 full auto ref-keratometer, Tokyo, Japan) and confirmed by subjective examination.
aACAo The biggest advantage of EVO ICL surgery is that it offers hope for better vision without glasses to also those patients who are not eligible for refractive surgeries like LASIK due to either very high
refractive errors or thin corneas
Majority (71.33%) caregivers were aware about occurrence of
refractive errors in children; however, only 25.3% of these were aware that uncorrected
refractive errors could lead to blindness.
On the other hand, among the people with a
refractive error, 13.4% were diagnosed with astigmatism; 3.6%, with hypermetropia, and 1.8%, with myopia (Figure 4).

Refractive Error And Visual Impairment Among Rural School-Age Children Of Goro District, Gurage Zone, Ethiopia," Ethiopian Journal of Health Sciences, vol.
Out of 900 students in 3 schools, 190 were known to be affected with
refractive error; hence, the prevalence of known case of
refractive error was 21%.
And for myopic subjects, as VRT was collected both before and after correction of the
refractive error their data were noted in the following way: Myopic corrected red reaction time, myopic uncorrected red reaction time, myopic corrected green reaction time, and myopic uncorrected green reaction time.
This growth can be attributed to factors such as rising prevalence of
refractive errors and cataract, increasing technological advancements in femtosecond lasers, increasing applications, and regulatory approvals of femtosecond lasers.
During the ceremony the project of screening of School Children for the
refractive errors in the district Hafizabad with the support of FHF was also launched.
Myopia is that
refractive error in which the light is brought to a focus in front of the retina, while in hyperopia it is brought to a focus behind the retina.
