Corneal conjunctivalization management with high Dk RGP contact lenses

To describe the management of corneal conjunctivalization with a high Dk RGP contact lens (CL) fitting.

A high Dk RGP CL (Menicon Z-alpha Dk=189, Japan) was fitted, after temporary suspension of CL wear (6 months and 3 weeks), in two patients (a 36-year-old female and a 38-year-old male) who had corneal conjunctivalization secondary to low Dk soft CL wear. Both patients had worn their soft CLs 12-14 h per day without symptoms for the previous 18-20 years.

After 9-15 months of high Dk RGP wear, all signs of corneal conjunctivalization had disappeared (corneal vascularization, late fluorescein stain, etc.) and patients wore their RGP CL comfortably. Corneal conjunctivalization was resolved with non-invasive procedures (temporary discontinuation, preservative-free artificial tears and high Dk RGP CL fitting) and thus other treatments (topical or surgical treatments such as limbus transplantation, amniotic membrane transplant or others) were not necessary.

Short temporary suspension of CL wear (3 weeks), preservative-free artificial tears and refitting with high oxygen permeability RGP CL may be an alternative for the management of corneal conjunctivalization secondary to CL wear.
