When the lens loses the support that is given to her by zonular strings, it is moved to the front eye chamber or in the rear part to the vitreous, where it can move freely.
If zonular strings are still attached, subluxation occurs – partial shift of the lens. Lent is seen in the form of drops, and the iris trembles because there is no support behind it. It loses its power of accommodation and stays hyperopic. Any lens that is luxated is also blurred.
