In the ICD-8 (1965), “sexual deviations” were categorized as homosexuality, fetishism, pedophilia, transvestism, exhibitionism, voyeurism, sadism and masochism. ICD-9
In the ICD-9 (1975), the category of sexual deviations and disorders was expanded to include transsexualism, sexual dysfunctions, and psychosexual identity disorders. The list contained homosexuality, bestiality, pedophilia, transvestism, exhibitionism, transexualism, Disorders of psychosexual identity, frigidity and impotence, Other sexual deviations and disorders (including fetishism, masochism, and sadism). ICD-10
In the ICD-10 (1990), the category "sexual deviations and disorders" was divided into several subcategories. Paraphilias were placed in subcategory of "sexual preference disorders". The list included fetishism, fetishistic transvestism, exhibitionism, voyeurism, pedophilia, sadomasochism and other disorders of sexual preference (including frotteurism, necrophilia, and zoophilia). Homosexuality was removed from the list, but ego-dystonic sexual orientation was still considered a deviation which was placed in subcategory "psychological and behavioural disorders associated with sexual development and orientation". ICD-11
In the ICD-11 (2022), "paraphilia" has been replaced with "paraphilic disorder". Any paraphilia and any other arousal pattern by itself no longer constitutes a disorder. To date, the diagnosis must meet criteria of paraphilia and one of the following:
1) a marked distress associated with arousal pattern (but not one that comes from rejection or fear of rejection);
2) the person has acted on the arousal pattern towards unwilling others or others considered as unable to give consent;
3) a serious risk of injury or death.
Bowman also attempted to restore vision by pulling on the iris with a fine hook inserted through the cornea and stretching the pupil into a vertical slit, like that of a cat. He reported that he had had a measure of success with the technique, restoring vision to an 18-year-old woman who had previously been unable to count fingers at a distance of 8 inches (20 cm). By 1869, when the pioneering Swiss ophthalmologist Johann Horner wrote a thesis entitled On the treatment of keratoconus, the disorder had acquired its current name. The treatment at that time, endorsed by the leading German ophthalmologist Albrecht von Graefe, was an attempt to physically reshape the cornea by chemical cauterization with a silver nitrate solution and application of a miosis-causing agent with a pressure dressing. In 1888, the treatment of keratoconus became one of the first practical applications of the then newly invented contact lens, when the French physician Eugène Kalt manufactured a glass scleral shell that improved vision by compressing the cornea into a more regular shape. Since the start of the 20th century, research on keratoconus has both improved understanding of the disease and greatly expanded the range of treatment options. The first successful corneal transplantation to treat keratoconus was done in 1936 by Ramón Castroviejo. Society and culture
According to the findings of the Collaborative Longitudinal Evaluation of Keratoconus (CLEK), people who have keratoconus could be expected to pay more than $25,000 over their lifetime post-diagnosis, with a standard deviation of $19,396.
