ABSTRACT
OBJECTIVE: To report clinical features and visual outcomes following eyelet fractures of scleral-sutured enVista MX60 (Bausch + Lomb) intraocular lenses (IOL). DESIGN: Retrospective, multi-center, multi-surgeon, observational case series. METHODS: Study Population: Patients with scleral-sutured enVista MX60 IOLs that experienced either an intraoperative or post-operative eyelet fracture associated with dislocation or subluxation. PROCEDURES: All records were reviewed for patients with a dislocated or subluxed scleral-sutured enVista MX60 IOL. Clinical features and outcomes were gathered. Main Outcome Measures: Clinical setting, surgical technique, complications, and visual acuity. RESULTS: A total of 25 scleral-sutured enVista MX60 IOLs displacements secondary to eyelet fractures in 23 eyes of 23 patients were included. There were 20 IOLs that sustained a postoperative fracture and 5 IOLs that sustained an intraoperative fracture. Of the postoperative fractures, 7 were dislocated and 13 were subluxed. Gore-Tex was the suture of choice for 19 of the postoperative fractures and all 5 of the intraoperative fractures, and Prolene was used for 1 postoperative fracture. The mean time until postoperative fracture was 96 ± 125 days, and the median time was 61 (IQR 48-144) days. Of the postoperative fractures, new MX60s were sutured in 10 patients, and 2 of them experienced repeat displacements due to a new eyelet fracture. In the intraoperative fracture group, new MX60s were sutured in 4 patients and an Akreos AO60 lens was placed in the 5th patient. The mean preoperative best-corrected logMAR visual acuity for all patients improved from 1.2 ± 0.8 (20/317 Snellen equivalent) to 0.5 ± 0.5 (20/63 Snellen equivalent) at most recent follow-up after lens replacement. CONCLUSIONS: Scleral-sutured MX60 intraocular lenses can experience intraoperative or postoperative eyelet fractures, resulting in lens subluxation or dislocation. Surgeons should be aware of this complication when evaluating secondary intraocular lens options.
