Tenders are invited for Supply of Autorefractometer
Subjects with no ocular pathology, uncorrected 20/20 vision, autorefractometer
values less than 1.
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.
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.
Tenders are invited for Supply of Handheld Paediatic Autorefractometer
Objective cycloplegic refraction measurements were done using an autorefractometer
(KR-1 Auto Kerato-Refractometer, Topcon, Japan).
Limitations of the study: First one is its retrospective design, second one is relatively small sample size, third one is retinoscopy and autorefractometer
were used for some of the patients to evaluate the refractive error.
Anterior segment evaluation done using slit lamp and refraction was done by using Huwitz autorefractometer
was used to calculate the refractive error.
Refractive errors were measured by autorefractometer
(Topcon KR 8800, Oakland, NJ, USA) and recorded as spherical equivalent.
