Abstract
Purpose
To report the occurrence and the outcomes of 2 cases of spontaneous extrusion of 3-piece intraocular lens (IOL) through a Gundersen conjunctival flap performed for tectonic purposes after multiple failed penetrating keratoplasties (PKs).
Methods
A 70-year-old woman (Patient #1) with severe dry eye disease who had undergone cataract surgery with posterior chamber 3-piece IOL implantation, multiple PKs and Gundersen conjunctival flap in her left eye presented with partial extrusion of the optic and the inferior haptic of the IOL through the conjunctival flap. Inferior symblepharon and keratinization of the entire ocular surface were also present. A 64-year-old diabetic man (Patient #2) with history of cataract surgery with a posterior chamber IOL implantation, multiple PKs for keratoconus and Gunderson conjunctival flap in his right eye presented with partial extrusion of IOL optic through the conjunctival flap.
Results
Patient #1 refused a further surgery and IOL was removed at the slit lamp. Currently, 3 months after IOL extrusion, corneal perforation self-sealed, visual acuity of light perception is maintained, and the patient does not complain any symptoms of ocular discomfort or pain. In Patient #2, tectonic PK combined with IOL removal and anterior vitrectomy was performed. Currently, 1 month postoperatively corneal graft is clear, intraocular pressure is normal, and patient's vision is counting fingers.
Conclusions
In both cases, IOL extrusion occurred spontaneously through a Gunderson conjunctival flap. Including the underlying Tenon's capsule in the conjunctival graft could increase its tectonic support, potentially avoiding this complication.
