phacodonesis

An obsolete term for tremulousness of the lens.

phacodonesis 

A tremulous condition of the crystalline lens. It usually results from an injury to the eye in which some or most of the zonular fibres are broken. See iridodonesis.

A significant zonular instability can cause phacodonesis, (7) spontaneous subluxation of the lens8 (Fig.
If obvious phacodonesis is present, then it is advisable to insert a CTR on completing the capsulorhexis to stabilize the capsular bag for phacoemulsification and cortical removal.
As a result, postoperative pseudo phacodonesis can lead to pigment dispersion and chronic inflammation.
3,4,5,6,7,8) Previous studies showed that zonular weakness with subsequent phacodonesis in PEX syndrome could lead to anterior lens movement, increased lens thickness (LT) and shallow anterior chamber.

There may be no clinical signs in the anterior segment, although a history of ocular trauma may be corroborated by pupillary sphincter ruptures, lens subluxation, or phacodonesis.
22) It may be indicated by the presence of a subluxated lens, phacodonesis (increased mobility of the lens) or iridodonesis (increased mobility or tremulousness of the iris).
