ABSTRACT:
A biological material is prepared for use in ophthalmology by steps of providing animal pericardium, subjecting the animal pericardium to multiple steps of freezing and thawing in a salt solution and incubating the animal pericardium in a solution of ammonia and ethyl alcohol. The multiple steps of freezing and thawing are conducted in a mixture of about 0.9% sodium chloride solution and distilled water in about 1:1 proportions of sodium chloride solution to distilled water. The incubating step is conducted in a mixture of 1% ammonia solution and 1% ethyl alcohol solution in about 1:1 proportions of ammonia solution to ethyl alcohol solution over a period of 48 to 72 hours.
