Highlights
• Ophthalmic viscoelastic devices (OVDs) were designed composed of HPC and ɩ-carrageenan (Carr).
• The rheological and compressional properties of the polymer blends were characterised.
• HPC and Carr were shown to physically interact in both dilute and gel states.
• Binary platforms offered a wide range of rheological and compressional properties.
• Platforms containing 3% HPC and 1% or 2% Carr exhibited properties advantageous for use as
OVDs
