Purpose

To compare short-term visual functions changes in myopic children who had worn the defocus incorporated multiple segment (defocus incorporated multiple segment), defocus incorporated multiple segment with triple enhanced design (defocus incorporated multiple segment TED), and single-vision (single-vision) spectacle lenses.

Methods

Wore defocus incorporated multiple segment, defocus incorporated multiple segment TED and single-vision spectacle lenses in random order.

logMAR

seeing detail slightly off to the side was mildly, not meaningfully, worse

More results

Most visual functions showed no differences before and after lens wear.

Central high- and low-contrast distance visual acuity and central high-contrast near visual acuity under room and dim lighting were unaffected by defocus incorporated multiple segment and defocus incorporated multiple segment TED spectacle lenses compared to single-vision lenses (all P > 0.05).

More results

However, these reductions are unlikely to represent a clinically meaningful impairment in visual function.

Most children adapted and accepted the defocus incorporated multiple segment TED spectacle lenses well.

Conclusion

Defocus incorporated multiple segment TED spectacle lenses demonstrated visual performance comparable to defocus incorporated multiple segment and single-vision spectacle lenses.
