Abstract

Objectives To evaluate the technique of aphakic iris-claw (IC) intraocular lens (IOL) implantation, the visual outcome, and the incidence of postoperative complications. Background Several techniques are available for visual rehabilitation of eyes with inadequate capsular support following complicated cataract surgery or owing to lens subluxation or dislocation. IC-IOL is an effective option with several advantages over other techniques. Patients and methods Patients with inadequate capsular support underwent aphakic IC-IOL implantation. We used two techniques: anterior chamber (AC) and retropupillary fixation of IC lens. Eyes were evaluated for uncorrected and corrected distance visual acuity, intraocular pressure (IOP), and the incidence of postoperative complications. Results The study comprised 12 eyes of 11 patients. Indications for surgery included aphakia following complicated cataract surgery (n = 8), lens dislocation (n = 1), and lens subluxation (n = 3). Eight eyes had AC IC lens implantation and four eyes underwent retropupillary implantation. The final postoperative uncorrected and corrected distance visual acuity improved significantly compared with preoperative values. There was no statistically significant difference between preoperative and postoperative IOP. Postoperative complications included corneal edema, IOP elevation, inflammatory reaction, pupil ovalization, vitreous hemorrhage, and lens disenclavation. There was no statistically significant difference between the two techniques of implantation regarding any of the studied variables. Conclusion Aphakic IC-IOL is an effective option for visual rehabilitation in eyes with inadequate capsular support, providing a good visual outcome and high safety profile. Both AC and retropupillary fixation can achieve a satisfactory outcome.
