Abstract

Objective  To report epithelial perilenticular opacity as a new complication ofintracorneal inlay implantation for the correction of hyperopia.

Design  Prospective observational case series.

Participants  Eleven eyes of 7 patients underwent intracorneal inlay implantationfor the correction of hyperopia.

Methods  Intracorneal inlays were implanted onto the stromal bed by using a microkeratomecut to create an inferior hinged corneal flap.

Main Outcome Measures  Postoperative complication occurrence of intracorneal perilenticularopacity, microbiological laboratory analysis, histopathological analysis,and confocal microscopy study.

Results  Of 11 implanted eyes, 5 showed diffuse perilenticular opacity of varyingintensity that was unresponsive to steroid use following intracorneal inlayimplantation. All patients had moderate to severe loss of best-corrected visualacuity. The inlays showed deposits at the edge and on the surface. Confocalmicroscopy in all eyes produced images compatible with the confocal morphologicfeatures of epithelial cells. Explantation of inlays was performed in 5 eyes.The histopathologic study showed the presence of epithelial cells, and microbiologicalanalysis and cultures were negative for bacteria, fungi, and mycobacteria.

Conclusion  Epithelial perilenticular opacity is a new and serious complicationin patients with intracorneal inlay implantation for the correction of hyperopia.
