Corneal sensitivity was measured prior to inserting hydrophilic lenses for 8 hours, just after removal, and again 15 min and 1 hour later. It was found that the sensitivity was not significantly different immediately after 8 hours of wear as compared to its initial value in the morning. However, after the lens had been removed for 1 hour, corneal sensitivity had diminished to a significant level indicating that soft lenses affected the sensitivity. This is understandable because corneal sensitivity normally increases throughout the day. It is felt that the reduction of corneal sensitivity induced by soft lenses may be due to some corneal oedema which might develop because the lenses hinder the evaporation of tears.
