Crystalline lens thickness may be systematic marker for accommodative effort in presbyopia

Key takeaways:

Lens thickness increased with accommodative demand across all age groups by an average of 0.013 mm/D.

Compared with emmetropes, myopes had significantly shorter accommodation response time.

SALT LAKE CITY — The thickness of the crystalline lens could be a marker for accommodative effort in presbyopic eyes, according to data presented at the Association for Research in Vision and Ophthalmology meeting .

“We’ve found lens thickness to be a very systematic parameter in various ways,” Susana Marcos , PhD , told Healio. “Lens thickness can be a good marker for accommodative effort and something to look at perhaps as a marker to trigger some accommodating device.”

The finding was enabled by a custom OCT system developed in the lab of Marcos, director of the Center
