Purpose: (a) to measure the post–operative accomodative amplitude in eyes implanted with "accomodative" IOLs (b) to explore anterior segment changes upon IOL implantation Methods: Study design: prospective, randomized, controlled clinical trial, 12 month . Population: 41 patients (59 eyes), scheduled for cataract surgery (clear cornea phacoemulsification in local anaesthesia, two surgeons, GM and SAG) , agreed to participate in the study. In 26 eyes (17 patients) an AT45 IOL was implanted. 25 eyes (16 patients) were scheduled for a 1CU IOL, 8 eyes (8 patients) were scheduled for a non–accomodative acrylic foldable IOL.. Age : 45–65 years. Pre–operative best corrected visual acuity: 20/63 – 20/32. Study procedures: (a) accomodation measured by adding a negative sphere to the far–distance correction until 4/5 letters of the smallest detectable line were properly identified. (b) anterior chamber depth (i.e. the distance between the posterior endothelium and the anterior optic of the IOL ) and the amplitude of the scleral–ciliary process angle were measured by UBM in an accomodation–solicited condition and in a relaxation state. The measurements were made on the individual UBM images by two "masked" independent observers (RT and PM Results: Post–operative uncorrected far distance visual acuity ranged between 20/25 and 20/16. The 12–month data on accomodation, and on the decrease of (a) the AC depth and (b) the sclero–ciliary angle, upon solicited accomodation, are summarized in the table:
