[The choice of methods of intraocular lens implantation in traumatic cataract in the absence of capsular and zonular support].
OBJECTIVE
To study the choice between the methods of anterior chamber intraocular lens (AC-IOL) implantation and posterior chamber IOL suture fixation in traumatic cataract without posterior capsular support.


METHODS
The study included 86 cases (86 eyes) with traumatic cataract. A new flexible open-loop one piece PMMA IOL was implanted in the AC-IOL group of 56 cases (56 eyes); fixation of a C-loop one piece PMMA IOL at ciliary sulcus with two sutures was performed on 30 cases (30 eyes) in the posterior chamber IOL (PC-IOL) group.


RESULTS
The follow-up period was 1 - 42 months. The visual acuity 0.5 or better was in 71.4% (40/56) in AC-IOL group, in 90.0% (27/30) in PC-IOL group; 1.0 or better was in 39.3% (22/56) in AC-IOL group, in 46.7% (14/30) in PC-IOL group.


CONCLUSIONS
Both AC-IOL implantation and PC-IOL suture fixation are the remedy methods when the PC-IOL intracapsular implantation is unsuccessful. The AC-IOL is suitable for old persons with good anterior segment (cornea, iris and the angle of anterior chamber) and poor posterior segment (vitreous, retina) situations, while the PC-IOL suture fixation is suitable for the young with relatively poor anterior segment and good posterior segment conditions.
