    Abstract:
    PURPOSE: To evaluate the efficacy and safety of iris suture fixation of out-of-the-bag dislocated three-piece intraocular lenses (IOL). METHODS: In a retrospective interventional consecutive case series, a chart review was performed in two groups of patients: fourteen patients with a dislocated out-of-the-bag three-piece IOL that underwent IOL fixation to the iris using the Siepser sliding knot technique (Iris group) and 18 patients with in-the-bag dislocation that underwent IOL exchange with a new scleral-sutured IOL (Exchange group). The Iris and Exchange groups were compared regarding surgical safety and efficacy. The median follow-up time was 13.5 months [interquartile range (IQR), 10-20] in the Iris group and 12.5 (IQR, 10-14) in the Exchange group. RESULTS: The best corrected visual acuity (BCVA) improved significantly in both groups (p = 0.005 and 0.00006, respectively). No difference in final BCVA was seen between the groups. Significantly less surgically induced astigmatism (p = 0.03) and a lower number of postoperative visits (p = 0.0006) was noted in the Iris group. Considering the type of surgery, there were few complications in the present material. CONCLUSION: In the study, suturing dislocated three-piece IOLs to the iris appeared to be an acceptable surgical management with less surgically induced corneal astigmatism and fewer postoperative visits than IOL exchange. A larger study with a longer follow-up time would be desirable to confirm the results.
