Abstract
Introduction Iris prostheses are an integral tool for the management of symptoms in the setting of damaged, insufficient, or absent irides. Fixation of a custom iris prosthesis in the absence of capsular support raises similar challenges to the fixation of an intraocular lens (IOLs) without capsular support. Centration and planar orientation of these larger iris devices are perhaps even more important than with IOLs. Methods We describe two variations of a reliably reproducible suture fixation technique for securing these special devices using a modification of the tiltless, centration-adjustable suture technique for sclerally-fixated posterior chamber IOLs. Results We described a few techniques that are safe and reproductible. That have been used in more than 300 cases in our co-hort with success and follow-ups of over 10 year. Conclusion We go over the technique step-by-step, highlighting the critical steps and pitfalls to avoid complications and achieve satisfactory results and aiming to get more surgeons to use these techniques and help facilitate the steep learning curve some of the steps might have.
