Novel theory for treatment of presbyopia: Rejuvenation of zonular fibers by capsular anterior annular peripheral shrinkage (CAPS)

"nPresbyopia is the gradual age-related loss of accommodation. The precise mechanism responsible for presbyopia has not been clearly defined. Recently, Schachar has proposed a radically different theory of accommodation. Schachar theorizes that presbyopia could be corrected if the ciliary muscles could be stretched a small amount to allow them to function on the lens. We propose laser correction of presbyopia with capsular anterior annular peripheral shrinkage is a possible treatment for augmenting the transmission of the contraction force of the ciliary muscle through the zonular fibers to the lens capsule. The resulted shrinkage increase the distance between the lens equator and ciliary muscle leading to restoring the adequate zonular fibers tension and reversing the effect of age-related lens growth on the near vision.
