title: Anteroposterior shift in rigid and soft implants supported by the intraocular capsular bag.
abstract: We compared the depth of the anterior chamber and the optimal distance refraction in a group of patients with soft and rigid intraocular implants under pilocarpine (maximal ciliary contraction) and cyclopentolate (maximal ciliary relaxation) in order to determine if lens movement might account for the apparent accommodation phenomenon. Lens shifts ranging from 1.5 to 0.02 mm and refractive variations up to 1 D were found. However, the discrepancies between amount of shift and refractive variations suggest that lens movement does not play a relevant role in this phenomenon.
