Abstract Background This study aimed to investigate the incidence of and risk factors for the anterior chamber migration of an intravitreal dexamethasone implant (Ozurdex®). Methods A retrospective review of 640 consecutive intravitreal dexamethasone implant injections was conducted from February 2011 through February 2018 at the University Eye Hospital in Tübingen, Germany. Those patients who experienced anterior chamber dexamethasone implant migrations were identified, as well as the reasons for the anterior chamber migration. The surgical histories were obtained and comprehensive ophthalmic examinations were conducted for all of the eyes. Cross-tabulations, chi-squared tests, and Fisher's exact tests were used to assess the influences of different factors on the anterior chamber implant migrations. Results Overall, 4 eyes of four patients (0.63%) showed anterior chamber implant migrations. All four of the eyes were pseudophakic, and they had undergone prior vitrectomies. Three eyes had sclerally-fixated intraocular lenses, and one eye had a posterior chamber intraocular lens in the capsular bag, with a capsular tension ring due to partial zonular dehiscence. When comparing the vitrectomized eyes with reduced zonular/capsular bag complex integrity to the vitrectomized pseudophakic eyes with intact zonular/capsular bags, the former were significantly associated with an increased risk of anterior chamber implant migration (P = 0.008). The vitrectomized pseudophakic eyes, in contrast to the nonvitrectomized pseudophakic eyes, were significantly associated with an increased risk of anterior chamber implant migration (P = 0.009). Conclusions The anterior chamber migration of an intravitreal dexamethasone implant is a serious complication. To minimize the risk of permanent corneal edema, immediate removal of the implant with a 20-gauge alligator forceps over a 2.75-mm long clear corneal tunnel is important. Those patients with insufficient zonular support, defects, or missing posterior capsular membranes and vitrectomy histories present a high risk of anterior chamber dexamethasone implant migration.

Abstract Objective We investigated the long-term visual outcomes and ocular complications of primary scleral-fixated posterior chamber intraocular lenses (SF-PC-IOLs) in patients with congenital lens subluxation. Methods We enrolled 53 patients (77 eyes) with congenital lens subluxation caused by ectopia lentis, Marfan syndrome, and Weill–Marchesani syndrome who underwent primary implantation of a SF-PC-IOL. All patients underwent a complete ophthalmic examination include visual acuity (VA), intraocular pressure (IOP), intraocular lenses (IOL) position, intraoperative complications and postoperative complications. Cox regression analysis and survival analysis were used to evaluate the risk factors for postoperative complications. Results Seventy seven eyes from 53 patients were included. Mean age at surgery was 23 ± 20 years (5 to 67 years), with a mean follow-up of 39 ± 27 months (12 to 130 months). The best-corrected VA improved from 0.84 ± 0.55 to 0.26 ± 0.43 logarithms of the minimum angle of resolution (p < 0.001). Best-corrected VA improved postoperatively in 73 eyes (94%). The main causes of reduced vision after surgery were retinal pathologies and amblyopia. Complications included transient intraocular haemorrhage (2 eyes, 2.6%), early vitreous incarceration (2 eyes, 2.6%), retinal detachment (6 eyes, 7.8%) and IOL dislocation (3 eyes, 3.9%). Cox regression showed that postoperative eye trauma was a risk factor for long-term postoperative complications. Conclusion SF-PC-IOLs provide good visual outcomes in patients with congenital lens subluxation. The SF-PC-IOLs showed good stability, except in patients suffering from postsurgical eye trauma.
