Abstract

AIM: To evaluate the effect of continuous wearing of Stellest™ spectacle lenses on refractive dynamics, accommodation, and binocular interaction after 6 months and 1 year.

MATERIAL AND METHODS: Children aged 8–13 years who had mild-to-moderate myopia were included. Stellest™ spectacle lenses were prescribed to 35 children with myopia (3.15±0.19 D on average). The control group consisted of 32 children with myopia (2.68±0.18 D on average) using single-vision correction. Refraction, axial length of the eye, accommodation, and binocular interaction were evaluated.

RESULTS: After 1 year, the average increase in refraction in the Stellest™ group was 0.19±0.07 D. A decrease in the annual progression gradient (APG) was observed in 82.4% of cases and averaged 0.72±0.1 D. The axial length of the eye increased by an average of 0.08±0.02 mm. In the control group, after 1 year of observation, the average increase in refraction was 0.6±0.07 D. A decrease in APG was observed in 51.6% of the cases and averaged 0.26±0.12 D. The axial length of the eye increased by an average of 0.26±0.03 mm. After 1 year, the increase in refraction and growth of the axial length of the eye in the Stellest ™ group was less than that in the control group by 68.3% and 69.2%, respectively. In the Stellest™ group, positive relative accommodation (PRA) increased after 1 year by 1.06±0.14 D and that in the control group by 0.6±0.16 D. The difference was significant (p <0.02). No differences were found between the groups in terms of objective indicators of accommodation. The stabilization effect in Stellest™ spectacle lenses was the least pronounced with esophoria.

CONCLUSION: The use of Stellest™ spectacle lenses slows down the progression of myopia in children and reduces APG by more than two times. A significant increase in PRA was found in children using Stellest™ spectacle lenses for 1 year compared with children using single-vision correction.
