A Case of Traumatic Soft Contact Lens Dislocation Into the Vitreous Space After Corneal Perforation in a Phakic Eye: A Novel Indication for Membraneblue-Dual

Abstract

Purpose: To describe a case of traumatic soft contact lens dislocation into the vitreous space after a large-sized corneal perforation with a clout nail, causing aniridia but leaving the crystalline lens intact.Methods: A case report of a 44-year-old male patient with a corneal perforation.Results: The patient presented with a traumatic corneal perforation after a large clout nail impacted on his left eye. Aniridia and inferior zonulolysis were seen, but the crystalline lens was perfectly clear. Because computed tomography imaging and B-scan ultrasonography showed no signs of intraocular foreign body, a vitrectomy was performed seven days after primary repair to allow for proper wound closure. During vitrectomy, a completely intact soft contact lens was found in the vitreous cavity. The soft contact lens was stained with MembraneBlue-Dual (D.O.R.C., the Netherlands) to enhance visualization and ensure complete removal by the vitreous cutter.Conclusion: MembraneBlue-Dual can be used to facilitate complete removal of a clear and otherwise difficult to see corneal contact lens from the vitreous cavity. This case also demonstrates the importance of exploratory vitrectomy in all trauma cases with posterior segment involvement, even when imaging modalities show no signs of intraocular foreign bodies.
