Surgical treatment of traumatic dislocated lenses

Purpose: To determine the surgical strategy in traumatic lens dislocations
depending on the degree of lens fixation to the ocular structures using
ultrasonography and distant infrared thermography.

Methods: The present report provides the results of surgical treatment of
71 patients observed in the Republic*s reconstructive eye microsurgery
center in the period between 1994 - 2001. 55 patients of these had totally
dislocated free-moving lenses. 16 cases had the lens fixed to intraocular
structures ( this group of patients did not have the lens removed ).
B-scanning was used to asses the condition of the vitreous around the
dislocated lens and the strenght of its fixation to the intraocular
structures. Distant infra-red thermography made it possible to correctly
determine post-traumatic uveitis.

Results: The operations made were as follows; 19 patients had pars plana
lens-vitrectomy; 36 patients had the anterior chamber freed from vitreous,
with the lens removed with the help of a loop under ophthalmoscopic control.
In case of need, we performed iris plastic operations ( 17 cases ),
antiglaucoma operations (12 cases ), scleral buckling with vitrectomy,
fluorocarbon oil, and a tamponade of gas or silicone oil ( 18 cases ).
Postoperatively, visual acuity improved in 80 % of patients.
