Our objective was to evaluate the long-term stability of transsclerall
y sutured posterior-chamber lens (PCL) haptics. A total of 22 patients
(26 eyes) were examined 29-50 months postoperatively by ultrasound bi
omicroscopy (UBM) to determine the exact haptic position in relation t
o the iris base, ciliary sulcus, pars plicata, and pars plana. In all
eyes, endoscopy had been performed intraoperatively immediately after
PCL insertion and suture fixation of the haptic. We could locate all 5
2 haptics by UBM. Intraoperative haptic localization was compared with
the postoperative position. UBM confirmed the endoscopic position in
81% of cases; 19% of the haptics showed a clinically undetectable disl
ocation. Secondary dislocations were analyzed in correlation with the
intraoperative endoscopic transscleral suture penetration site and the
primary position of the two haptics of one PCL. Loosening of the fixa
tion suture together with primary asymmetry of the two, haptics of one
PCL apparently contributes to a slight dislocation.
