Prospective, nonrandomized clinical study. The study included 46 eye s which received an anterior chamber angle supported (Bausch &Lomb NuVita; 10 eyes) , anterior chamber iris fixated (Ophtec Artisan; 20 eyes) or ciliary sulc us implanted phakic IOL (Staar ICL; 16 eyes). The distance between the phakic I OL and the crystalline lens and the cornea as well as rotation around the optica l axis was evaluated using Scheimpflug photography at 1, 3 to 6, and 12 months p ostsurgery. The anterior chamber phakic IOLs showed no significant movement in a nteroposterior direction. The posterior chamber phakic IOL showed a significant movement toward the crystalline lens between postoperative months 3 and 12. The median amount of rotation around the optical axis between the 3 and the 12 mon th evaluation was 1.9 degrees (range= 0.0-33.5 degrees) for the NuVita, 0.6 deg rees (range=0.0 3.5 degrees) for the Artisan, and 0.9 degrees (range=0.2-2.3 d egrees) for the ICL. Four NuVita IOLs rotated more than 10 degrees. The angle s upported anterior chamber phakic IOLs showed a generally stable position regardi ng distance to cornea and natural lens, but rotation was observed in four IOLs. The iris fixated phakic IOL showed the highest overall stability. The posterior chamber phakic IOL was stable in terms of rotation but had a tendency to decrea se in distance toward the crystalline lens. Intraocular lenses implanted in phak ic eyes followed for 12 months demonstrate stable IOL position overall.展开更多
