Intraocular lens implantation with the passport system - First experiences and results

Background A new IOL implantation technique introduced in Germany since December 1995 is presented - the one-piece-plate-haptic silicone lens implantable with the Passport system. Method From January to September 1996 in 291 patients after 3.2 mm clear cornea incision, capsulorhexis, phacoemulsification and implantation of an one-piece silicone posterior chamber lens with an implantation system was performed. The early post-operative results like visual outcome, astigmatism and complication rate are presented and compared to a group of 100 patients with implanted foldable three-piece silicone posterior chamber lenses. Results and discussion The first post-operative day no statistically significant differences in visual outcome (mean: one-piece 0.71; three-piece 0.69), in absolute astigmatism (mean diopter 0.82 one-piece; 0.91 three-piece), in axial position and in complication rate were detectable. Differences of this new implantation technique compared to the conventional technique are discussed. Conclusion The implantation of one-piece silicone lenses with the Passport system is a reliable and high quality alternative to conventional systems.
