PURPOSE. This study investigated whether refractive correction improved accommodative function of hyperopic children while engaged in two sustained near activities. METHODS. Sustained accommodative function of 63 participants (aged 5-10 years) with varying levels of uncorrected hyperopia (>/= +1.00 D and < + 5.00 D spherical equivalent in the least hyperopic eye) was measured using eccentric infrared photorefraction (PowerRef 3; PlusOptix, Germany). Binocular accommodation measures were recorded while participants engaged in 2 tasks at 25 cm for 15 minutes each: an active task (reading small print on an Amazon Kindle), and a passive task (watching an animated movie on liquid crystal display [LCD] screen). Participants also underwent a comprehensive visual assessment, including measurement of presenting visual acuity, prism cover test, and stereoacuity. Reading speed was assessed with and without hyperopic correction. Refractive error was determined by cycloplegic retinoscopy. RESULTS. Hyperopic refractive correction significantly improved accuracy of accommodative responses in both task (pairwise comparisons: t = -3.70, P = 0.001, and t = -4.93, P < 0.001 for reading and movie tasks, respectively). Accommodative microfluctuations increased with refractive correction in the reading task (F-(1,F-61) = 25.77, P < 0.001) but decreased in the movie task (F-(1,F-59) = 4.44, P = 0.04). Reading speed also significantly increased with refractive correction (F-(1,F-48) = 66.32, P < 0.001). CONCLUSIONS. Correcting low-moderate levels of hyperopia has a positive impact on accommodative performance during sustained near activity in some schoolchildren. For these children, prescribing hyperopic correction may benefit performance in near vision tasks.
