Since 1855, the dominant theory for accommodation is that of Hermann von Helmholtz. The Helmholtz mechanism of accommodation states that contraction of the ciliary muscle results in a release of the tension on the zonular fibers allowing the lens to round up and become more convex during accommodation to allow near objects to be brought into focus. Thus, according to Helmholtz, accommodation results in the movement of the equatorial edge of the lens away from the sclera and disaccommodation…

The mechanism of accommodation and presbyopia in the primate
- Medicine
- 1995
It is demonstrated that the lens is under increased zonular tension during accommodation and that presbyopia is not due to lens sclerosis or ciliary muscle atrophy, which disprove Helmholtz's longstanding, widely accepted theory of accommodation.
Mechanism of Accommodation

No working model lens, based on the Helmholtz’s theory, that has been developed can mimic the properties of the human crystalline lens during accommodation and does not explain the peripheral surface flattening and reduction in spherical aberration that have been reported to occur during accommodation.

The results indicate that the lens equator is under increased zonular tension during accommodation, in contradiction to Helmholtz's widely accepted theory of accommodation.

It appears that the thickness and uniformity of the scleral belt loop is critical to the proper positioning and efficacy of the SEB segments, and changes in spherical equivalence, axial length, and central keratometry readings were not statistically significant.

The ciliary muscle ring contracts about 0.8 mm in radius during maximum accommodation and this change in radius does not significantly alter as the eye ages between 15 and 45 years, but the force of contraction steadily increases over the same age period.

A distinct hardening of the nucleus as opposed to the cortex has been found to occur in lenses as young as 20 years of age, and coincides with the decrease in accommodation range and the onset of presbyopia.
