Cause and treatment of presbyopia with a method for increasing the amplitude of accommodation

Ann Ophthalmol. 1992 Dec;24(12):445-7, 452.


To understand the mechanism and cause of accommodation and presbyopia, the sclera in the region of the ciliary body of presbyopic patients was expanded. The amplitude of accommodation was increased in all presbyopic patients. A unique hypothesis of accommodation based on increased zonular tension is presented, which when applied clinically, results in a treatment for presbyopia.
