Table 1. Wet and dry weights of sheep lenses stored in the post mortem eye

Lenses were removed and weighed at various times after the enucleated sheep eyes were placed on ice. They were then fixed in 5% glutaraldehyde for 2 weeks before being dried at 80 °C until constant weight was attained. The table shows that the ratio of dry weight to wet weight, for the 200-day-old lenses, decreases with increasing time in the eye, indicative of water uptake. Standard deviations are listed in parentheses.
