 About 1800 several developments occurred which justify the speaking of a new period in the history of Molyneux’s problem. New accounts of patients operated on for cataracts were published, and shed fresh light on the issue. Whereas Cheselden had only noticed what his patient observed in more or less natural circumstances, later ophthalmologists performed experiments which showed whether their patients were able to see form, size, distance, etc. Some, such as Franz and Nunneley, were especially interested in Molyneux’s problem as such, and performed experiments with the prescribed globe and cube. Some of the reports were in agreement with that of Cheselden, others conflicted with it. The cases could not easily be compared, however, since the pre- and post-operative circumstances differed to such a great extent. As one might have expected, an extended scale of possible solutions to the Molyneux problem was brought under consideration.
