High ViscosityHigh viscosity lubricants are useful in severely symptomatic dry eyes; they have a tendency to blur vision but last longer than lowviscosity products. If symptoms are not controlled by artifical tears, consider cyclosprine 0.05% oil enulsion (Restasis), temporary or permanentpunctal occlusion therapy; tarsorraphy may be considered for severe cases of exposure keratopathy.88Trade Name Viscosity Osmolarity PreservativePreservative Free:Aquasite PF 250–750 cps 4 /800 cp 3 235 NCelluvisc 170 cs 1 /200–300 cp 3 270–350 NOcucoat PF 46 cs 1 285 ± 32 NRefresh Endura 150 cps 220–300 NPreserved:Aquasite 250–750 cps 4 /800 cp 3 235 2Ocucoat 46 cs 1 285 ± 32 3Ultra Tears 100–300 cps 2 270–330 3Unknown ViscosityTrade Name Viscosity Osmolarity PreservativeComfort Tears N/A N/A 2, 3Dry Eyes Lubricant Eye Drops N/A N/A 3Murocel N/A N/A 8Ocu-Tears PF N/A NTheratears N/A 170 NVisine Tears N/A 270–320 3Visine Pure Tears Portables N/A N
