BACKGROUND Uncorrected refractive errors are a leading cause of visual disability globally. This population-based study was done to estimate the prevalence of uncorrected refractive errors in adults aged 30 years and above of village Pawakah, Khyber Pakhtunkhwa (KPK), Pakistan. METHODS It was a cross-sectional survey in which 1000 individuals were included randomly. All the individuals were s...

purpose : to assess the visual and refractive outcomes after implantation of toric implantable collamer lens (t-icl) in compound myopic astigmatism methods : in this prospective study, 28 eyes with manifest refraction spherical equivalent (mrse) errors of -10.94±4.09 diopter (d) and mean cylindrical errors of -3.47±1.39 d underwent t-icl implantation. six months after surgery, best corrected an...

AIM To assess the barriers to the uptake of refraction services in the age group of 15-49 years in rural Andhra Pradesh, India. METHODS A population-based cross-sectional study was conducted using cluster random sampling to enumerate 3300 individuals from 55 clusters. A validated questionnaire was used to elicit information on barriers to utilisation of services among individuals with uncorre...

Some 12.8 million in the age group 5-15 years are visually impaired from uncorrected or inadequately corrected refractive errors. In Saudi Arabia, the size of this public health problem is not well defined especially among primary schoolchildren. The purpose of this cross-sectional study was to assess the prevalence and pattern of refractive errors among primary school children in Al Hassa, Sau...

BACKGROUND Dyslexia is defined as a reading and/or writing disability persisting after exclusion of organic causes. Studies show that ocular disorders, especially small refraction errors, hypoaccommodation and symptomatic heterophoria, are often not detected or treated in cases of reading and/or writing problems which were otherwise diagnosed as dyslexia. METHODS We evaluated the data of pati...

Background: Uncorrected errors of refraction are the leading cause moderate to severe visual impairment. This study helps determine risk factors and prevalence refractive error among medical students evaluate uncorrected acuity them. Aim was disturbances undergraduate students. Methods: A cross sectional conducted 200 Data on socio-demographic characteristics, type errors, for frequency eye exa...

Six months after surgery, best corrected and ...

BACKGROUND Independence from all optical aids, and freedom from unwanted symptoms, following cataract and lens surgery remains the ultimate goal of both patient and surgeon. The development of trifocal IOL technology provides an ever-increasing range of options. The purpose of our study is to understand the predictability, safety and efficacy of a new trifocal intraocular lens (IOL) following c...

BACKGROUND The USee device is a new self-refraction tool that allows users to determine their own refractive error. We evaluated the ease of use of USee in adults, and compared the refractive error correction achieved with USee to clinical manifest refraction. METHODS Sixty adults with uncorrected visual acuity <20/30 and spherical equivalent between -6.00 and +6.00 diopters completed manifes...
