Purpose
To report two cases of retropupillary fixation of an iris-claw intraocular lens (ICIOL) through a scleral tunnel to correct aphakia secondary to traumatic crystalline lens (CL) expulsion through a penetrating keratoplasty (PKP) wound dehiscence.
Setting
Ophthalmology department of Habib Thameur University Hospital, Tunis, Tunisia.
Methods
The medical records of the two patients were retrospectively reviewed.
Results
Case1:A 37-year-old woman with a history of PKP for keratoconus in the right eye presented with post-traumatic globe rupture at the graft-host junction, one year postoperatively. Ocular trauma was complicated with an expulsion of the CL through the wound dehiscence.
Case 2:A 17-year-old man with a history of bilateral keratoconus presented with blunt ocular trauma to his left eye a few months after PKP resulting in inferior wound dehiscence and expulsion of the CL.
After emergency wound closure, both patients were referred to our department for aphakia correction.Surgery was planned after 2 months. ICIOL was implanted through a superior 5.5 mm scleral tunnel after anterior vitrectomy. Postoperative recovery was unremarkable for both patients.
Conclusions
Traumatic wound dehiscence after PKP is rare, but may lead to serious complications, including crystalline lens expulsion. In these two cases, implantation of a retropupillary ICIOL through a scleral tunnel proved to be an effective technique to treat aphakia after PKP with good postoperative outcome.
