G&M 5827: "Records the removal of a cataract 'en masse' from a living subject. English edition, 1741." The author's only book, but an important one in the history of opthalmology. Includes seven innovations and observations first announced in this treatise, including the first extensive use of silver nitrate in treating eye diseases, the earliest use of silver nitrate in cases of ophthalmia neonatorum, and the first exact description of gonorrheal ophthalmia. "Major advances in the knowledge of the anatomy and physiology of the eye were made during the eighteenth century... French ophthalmologists were leaders in the field during the eighteenth century and also showed that the cataract is a clouding and hardening of the lens and, in addition, were responsible for developing the modern cataract operation... In February 1707, Saint-Yves had become perhaps the first individual to extract a cararact 'in masse' from the human eye... Saint-Yves' treatise on diseases of the eye, a comprehensive work, includes early descriptions of occlusion therapy for strabismus, silver nitrate therapy for eye diseases, pupil formation in secondary cataract, conjunctivitis angularis, zoster ophthalmicus and retinal detachment" ---- Norman 1880 & 1881. In the second work, "Sloane asserts the healing powers of an ointment whose prescription he had purchased from a former assistant of the deceased Dr. Luc Rugeley. The ointment, consisting of the fat of vipers (which Sloane has replaced with pig lard), zinc oxide, iron oxide, and aloe, claims to remove corneal scars and assuage eye pain." Albert & Norton 2144. Sir Hans Sloane was a leading London physician who succeeded Newton a President of the Royal Society and whose large book and manuscript collection was purchased by the state to become the nucleus of the British Library collection.
