Purpose: Trauma can give rise to several alterations on an IOL stability, with the risk of the breaking of the capsular bag and of the zonula. In this cases a new fixation of the IOL is called for, as it can't be set in a suitable bag anymore, as suggested by A. Mohr (1999). To present a case series of Iris-Claw IOLs implantations on the posterior Iris surface, in trauma cases.
Methods: A series of trauma cases with post-traumatic aphakia, and iris damages.
In all cases it is performed a posterior iris-claw IOL implantation, also in cases of iris damage, after iris and pupil reconstruction. After a cornel tunnel of 6 mm at h12, and a double service tunnel at h 3 and h 9 the IOL is introduced in the anterior chamber with a forceps, then it is pushed behind the iris. Finally, with a hook through 3 and 9 o'clock keratotomy two haptics are clawed in the iris tissue.
Results: 15 cases, follow up 12 months. IOL stable and centered. One case of subluxation due to lost of the fixation of one IOL in one side: then repositioned without any complications.
Conclusions: The iris fixing on the posterior iris plane allows us not to tilt the IOL, to observe in the patience the lower subjective dazzling, to notice the best stability given by the natural posterior-anterior flow and the best aesthetic result, as the observer doesn't see the classical reflection tilting, typical in a anterior iris-fixing IOL.
