Pre- and postcycloplegic refractive errors for both eyes were measured using a Humphrey-598 automated refractor and spherical equivalents of refractive error were calculated.
WebAug 15, 2024 · A cycloplegic refraction is often performed on children. Children have the ability to accommodate/focus a great deal. Also, children tend to focus at a close range and are unable to control their focusing when they are supposed to be looking at a far distance during an examination. WebSpasm of accommodation become evident as pesudomyopia or latent hyperopia. Therefore, cycloplegic refraction using cycloplegic drugs is an effective way to reduce fluctuation in accommodation or spasm of ciliary muscle. 1–3. The drug of choice should have a rapid onset, appropriate cyclopegic effect and minimum side effects.
