[Impact of short-term stopped-down spectacle wear on accommodation function].

The impact of short-term stopped-down spectacle wear on accommodation function was studied in 32 patients with myopic refraction from 1.25 to 5.25 diopters (mean refraction 3.48 +/- 0.86 diopters). In all patients, laser refractometry was made monocularly at 5, 1, and 0.33 meters from the screen. A 0.33-m distance study revealed slight changes (a 0.06-diopter reduction) in the accommodation expenditure index. Dynamic refraction and accordingly the accommodation expenditure index changed to the greatest extent when a 1-m study was conducted. At the same time, there was a statistically insignificant reduction by 0.21-diopter. Our highly-sensitive studies of changes in ocular accommodation function during short-term stopped-down spectacle wear revealed no considerable changes in accommodation expenditure in patients with myopic refraction.
