Incomplete femtosecond laser-assisted capsulotomy and lens fragmentation due to emulsified silicone oil in the anterior chamber.

Journal Article (Journal Article)

We report 2 cases involving femtosecond laser-assisted cataract surgery following a retinal-detachment repair performed 1 and 2 years earlier using silicone oil endotamponade that was subsequently removed. Preoperative slitlamp examination did not show emulsified silicone oil in the anterior chamber. Intraoperatively, however, emulsified silicone oil was seen on anterior segment optical coherence tomography (AS-OCT) as a distinct hyperreflective retrocorneal line and there was no penetration of the OCT signal or delivery of the femtosecond laser treatment through this area, resulting in incomplete capsulotomy and lens fragmentation in both cases. Because silicone oil has a lower density than aqueous and migrates superiorly, careful preoperative gonioscopic examination to evaluate for emulsified silicone oil in the superior angle is warranted in eyes having femtosecond laser-assisted cataract surgery after a vitrectomy with silicone-oil endotamponade. Review of intraoperative OCT images can detect emulsified silicone oil, which would allow the procedure to be modified appropriately to prevent complications.
