The aim of the study was to investigate postoperative complications and to determine with ultrasound biomicroscopy (UBM) the position of a foldable acrylic intraocular lens (IOL) implanted with a surgical technique of iris suturing in eyes without capsule support. Six eyes with iris-sutured IOLs were examined postoperatively with UBM. The examination included the position of haptics and their relationship to the surrounding structures. Other parameters studied were central anterior chamber depth, IOL iris contact and pigment dispersion. The position of all 12 haptics was determined. All haptics were in touch with the iris. Pigment dispersion was seen in two cases. The anterior chamber depth of the sutured eyes was normal. There was neither cystoid macular edema nor chronic uveitis postoperatively. In conclusion, in most cases surgical placement of iris-fixed lenses is a blind procedure and UBM could be an appropriate method to determine the position of IOL haptics postoperatively and to demonstrate that this surgical technique is reproducible, safe, and effective with the limitation of the difficulty of iris suturing IOL.

Abstract
The aim of the study was to investigate postoperative complications and to determine with ultrasound biomicroscopy (UBM) the position of a foldable acrylic intraocular lens (IOL) implanted with a surgical technique of iris suturing in eyes without capsule support. Six eyes with iris-sutured IOLs were examined postoperatively with UBM. The examination included the position of haptics and their relationship to the surrounding structures. Other parameters studied were central anterior chamber depth, IOL iris contact and pigment dispersion. The position of all 12 haptics was determined. All haptics were in touch with the iris. Pigment dispersion was seen in two cases. The anterior chamber depth of the sutured eyes was normal. There was neither cystoid macular edema nor chronic uveitis postoperatively. In conclusion, in most cases surgical placement of iris-fixed lenses is a blind procedure and UBM could be an appropriate method to determine the position of IOL haptics postoperatively and to demonstrate that this surgical technique is reproducible, safe, and effective with the limitation of the difficulty of iris suturing IOL.
