Screening of refractive errors, according to the defined protocols with required instruments (Snellen charts, refraction boxes with trial frames, autorefractometer, retinoscope, ophthalmoscope and hand-held slit lamp etc.) and logistics by a team of optometrists supervised by an ophthalmologist was managed in the schools.13 Visual Acuity (VA) of the study subjects was evaluated with the Standard Snellen Chart placed at a distance of six meters.
For pupil dilation, 1% cyclopentolate hydrochloride (Sikloplejin R; Abdi ibrahim ilac Sanayi, istanbul) eye drops were applied twice at 5 min intervals, and the mean of three measurements performed 30 min after the final application using an autorefractometer (Canon RK-F1) was taken.
Objective refractive error was measured with an autorefractometer (Canon RK-F1 full auto ref-keratometer, Tokyo, Japan) and confirmed by subjective examination.
An autorefractometer (RM-8800 Autorefractor, Topcon, Tokyo, Japan) was used for keratometry measurements and objective refraction.
Preoperatively, we measured the mean keratometric readings using an autorefractometer (ARK-700A, Nidek, Gamagori, Japan) and the central corneal thickness using an ultrasound pachymeter (DGH-500, DGH Technologies, Exton, US), the IOP using a noncontact tonometer (KT-500, Kowa, Tokyo, Japan), and the endothelial cell density using a noncontact specular microscope (SP-8800, Konan, Nishinomiya, Japan).
AIM: To compare the accuracy of the autorefractometer with traditional retinoscopy as a means of determining the approximate subjective refraction in children after cycloplegia.
All members of this family underwent complete eye examination using the slit lamp, autorefractometer, retinoscope, ophthalmoscope, glasses box, tonometry and complete cardiac test.
Keratometry and refractive measurements were taken with a noncontact autorefractometer (RK-F1; Canon, Tokyo, Japan).
A team comprising of one ophthalmologist and three nursing assistants trained in taking visual acuity (VA), equipped with Snellen's E chart, torches, autorefractometer, trial box, slit lamp, retinoscope and direct ophthalmoscope (Heine Beta 200) visited the school during working days of week for examination of the students.
Myopia was diagnosed on the basis of eye length measurement by ultrasound imaging using E-Z Scan AB 5500+, and taking into consideration vision defect confirmed by an autorefractometer Topcon KR 9800 after paralysis of accommodation (cycloplegia) with 1% Tropicamide.
Postoperative refraction was confirmed by using an autorefractometer (Nidek AR-1, Japan) at least six weeks after surgery.
Subjects with no ocular pathology, uncorrected 20/20 vision, autorefractometer values less than 1.0 D, and no history of ocular surgery were included.
