this includes ( i ) a determination of the pressure required to distend the capsule by a standard volume . ( ii ) the calculation from the photographed lens profiles of the degree of capsular contraction which occurs when the lens changes from the unaccommodated to the accommodated form . ( iii ) capsular volume changes in vitro are then related to the surface area changes calculated for the lens in vivo.2 .
