In vivo observation of the axial movement of intraocular lenses through an anterior eye segment analysis system.
The small axial movement of the anterior surface of implanted intraocular lenses (IOLs) were examined in pseudophakic eyes with one-piece and three-piece IOLs using an anterior eye segment analysis system. The movement was calculated as the distance between the posterior surface of the cornea and the anterior surface of an IOL under a normal pupil size, following the instillation of 1% pilocarpine and 1% cyclopentolate solutions, respectively. The axial movement including movement after instillation of pilocarpine and cyclopentolate was 0.17 +/- 0.06, 0.05 +/- 0.07 and 0.13 +/- 0.06 mm, in phakic eyes and eyes with one-piece and three-piece IOLs, respectively. Image analysis techniques using Scheimpflug images proved its usefulness in the research field of IOL implantation.
