Abstract

Cataract surgery is the most frequently performed surgical procedure in the western world. That persistent diplopia may occur following cataract surgery is well known. There are many mechanisms which have been described including operative damage to orbital soft tissues and extraocular muscles, central disruption of fusion, loss of previously adequate fusion (decompensated heterophoria), disclosure of previous strabismus or previously unrecognized systemic disorder (such as thyroid related orbitopathy) The purpose of this study is to establish the prevalence, clinical causes as well as treatment for patients with persistent diplopia following cataract surgery in a large series of Greek patients The prevalence of diplopia following cataract operation was1,04% . In all cases peribulbar anesthesia was used. Hyalorunidase was not used. In addition, vertical diplopia was more common (p=0.001) and left eyes were more affected although results did not reach statistical significance (p=0.133). Patients were divided in 4 etiology groups according to the cause of postoperative diplopia. Twenty nine patients were corrected with prisms, 9 needed strabismus surgery and 1 needed both surgery and prisms. In conclusion our report highlights that prevalence of diplopia related to cataract operation, although not common, may occur and in the present environment of heightened expectations by both patients and physicians, it is prudent to take measures to anticipate the possibility of postoperative diplopia after cataract surgery.
