Abstract Background This study aimed to compare the results of Chronos binocular/monocular refraction system, that measures objective and subjective ocular in one unit, findings obtained from a conventional autorefractometer using trial-frame real space. Methods Twenty-eight healthy volunteers (21.2 ± 1.5 years old) were included this study. Objective was measured two tests: system under binocular conditions monocular conditions. Subjective three binocular, conditions, space The measurement distance set 5.0 m for each test. All refractions converted into spherical equivalents (SEs). Results SE significantly more negative with condition (− 4.08 2.76 D) than 3.85 2.66 ( P = 0.002). Although, 3.55 2.67 3.33 2.75 0.002), 3.17 2.57 not different 0.33). Conclusion These suggest which can complete both tests single is suitable screening refraction, although it produces slightly myopic results. Furthermore, testing accuracy be equivalent real-space by switching condition.

The aims of the study were (1) to compare accuracy and intrasession variability noncycloplegic autorefraction (AR) obtained by a photorefractor conventional open-field autorefractors (2) evaluate impact accommodative binocular vision anomalies on autorefraction. Twenty-nine children adolescents aged 8-18 years examined. All instruments gave more myopic results than subjective refraction (SR). Mean differences between SR AR +0.52/-0.25×96∘ for photorefractor, +0.63/-0.31×93∘ autorefractor, +0.19/-0.26×94∘ instrument. appeared be most repeatable. examined was not statistically significant.

The study's objective was to compare the accuracy of retinoscopy and autorefraction for subjective correction in children. study conducted Department Ophthalmology at Nishtar Medical Hospital from June 2021 May 2022, it a prospective study. included 60 children aged between 6 15 years who had asthenopic symptoms blurring vision. were given cyclopentolate 1% eyedrops thrice intervals 10 minutes achieve cycloplegia. After an hour instilling eye drops, cycloplegic retinoscopy, autorefractometry performed. Three values each technique recorded, average calculated. three days, binocular monocular refraction performed until best-corrected visual acuity (BCVA) achieved. Results showed that 40.8% (49 eyes) hypermetric, 50% (60 myopic based on refraction. Comparison spherical error by eyes mean -1.36 ± .98 -1.08± .82 respectively (P=.07), hypermetropic 2.5± .22 2.45± (P=0.07). autorefractometer value -1.51 1.3 (P=.0001) while 2.39± .37 (P=0.0001).

Retinoscopy is arguably the most important method in eye clinic for diagnosing and managing refractive errors. Advantages of retinoscopy include its non-invasive nature, ability to assess patients all ages, usefulness with limited cooperation or communication skills.
