PURPOSE: To examine the surgical complications of transscleral sulcus suture of posterior chamber intraocular lenses (IOLs) and to compare the rates of surgical complications between patients in the nonendoscope-assisted and endoscope-assisted groups. SETTING: Kyoto University Hospital, Kyoto, Japan. METHODS: This retrospective nonrandomized study comprised 121 eyes of 115 patients who had transscleral sulcus suture fixation of an IOL by the ab externo method. Typical 3-port vitrectomy was performed in 26 eyes in which the needle entry site and the haptic location were controlled using an endoscope. RESULTS: During follow-up of at least 3 months, surgical complications in the nonendoscope-assisted group (95 eyes) included IOL dislocation in 22 eyes (23%), high astigmatism in 12 eyes (13%), transient ocular hypertension in 10 eyes (11%), vitreous hemorrhage in 5 eyes (5.3%), retinal detachment in 4 eyes (4.2%), and cystoid macular edema in 2 eyes (2.0%). In the endoscope-assisted group (26 eyes), the same complications were markedly decreased: there were no cases of IOL dislocation, high astigmatism, vitreous hemorrhage, retinal detachment, or cystoid macular edema; transient ocular hypertension occurred in 1 eye (3.8%). There was a statistically significant difference in the incidence of IOL dislocation between the 2 groups (P<.01). CONCLUSION: Using an endoscope for transscleral sulcus suturing of an IOL can be an effective technique to reduce surgical complications, especially postoperative IOL dislocation.
