Contact Lens-Assisted DMEK for Corneal Decompensation With an Anterior Chamber Intraocular Lens: A Novel Technique.

Abstract

Purpose: To describe a novel technique in which a contact lens was used to facilitate Descemet membrane endothelial keratoplasty (DMEK) in an eye with an anterior chamber intraocular lens (ACIOL).

Methods: A 71-year-old man with a long-standing ACIOL developed bullous keratopathy. As the patient was at high risk of complications due to multiple ocular comorbidities, DMEK was performed with the ACIOL left in the anterior chamber. An inserted cosmetic contact lens was used as a platform for the graft unfolding.

Results: Partial graft detachment on the third postoperative day required rebubbling. This successfully cleared up the cornea after a few weeks. At the one-month follow-up, the uncorrected distance visual acuity improved to 20/50, with an endothelial cell loss of 35.2%. Steroid-induced ocular hypertension necessitated a trabeculectomy by the fifth postoperative month. At the sixth follow-up month, endothelial cell loss was 64%.

Conclusions: Contact lens-assisted DMEK is a safe procedure for eyes with an ACIOL. However, good foresight is needed regarding whether the ACIOL should be kept or exchanged.
