Suction cup/contact lens complications following penetrating keratoplasty.


Journal Article

PURPOSE: Rigid gas permeable (RGP) contact lenses facilitate visual rehabilitation in cases of high or irregular corneal astigmatism following penetrating keratoplasty. A variety of plunger-like suction cup devices are available to assist in the removal of these lenses. METHODS: We report three patients with serious complications associated with the use of a suction cup device for contact lens removal following penetrating keratoplasty. RESULTS: Two patients suffered corneal wound dehiscence following contact lens removal; one contact lens was removed by the patient's spouse and the other was removed by a trained technician. A third patient triggered a graft rejection, and ultimately, graft failure, after a vigorous attempt at lens removal. CONCLUSIONS: Forces generated by suction cup devices during removal of RGP contact lenses are sufficient to cause significant trauma. Contact lenses with an apical clearance fit may augment these forces, with the potential for complications following penetrating keratoplasty.
