In the absence of normal capsular structures an intraocular lens may be implanted in various ways. The retropupillary fixation of an iris-claw-lens offers a new possibility.


We operated on 12 eyes of 12 patients with a traumatic or intraoperative loss of the capsular bag. A Verisyse aphakic-IOL (VRS A 54) was implanted through a small tunnel incision and fixed retropupillary on the iris. Axial length measurement was performed using partial coherence interferometry (IOL-Master). IOL power was calculated using the SRK/T formula with an adjusted A-constant (115,0). We evaluated intra- and postoperative complications, target refraction and subjective patient satisfaction in addition to bestcorrected visual acuity.


Postoperatively the IOLs showed a stable centered position in all cases. In three cases only a slight improvement in visual acuity (one line) occurred because of a preexistent corneal scar in one case and previous retinal detachment and retinal necrosis in two other cases. Furthermore in one case an increased anterior chamber flare was measured.


The retropupillary fixation seems to be a good option in patients in whom implantation of an IOL into the capsular bag is not possible. The IOLs always showed a stable centered position.
