Abstract Details

Purpose:

To estimate efficiency of surgical treatment of dislocations of IOL.

Setting:

The dislocation of an intraocular lens (IOL) continues to remain one of serious problems of surgery of a cataract (Aznabayev M. T., 2004), capable not only to reduce visual functions, but also to cause heavy endoocular complications (Stebnev S.D., 2009). Kazakh Research Institute of Eye Diseases, Almaty, Kazakhstan

Methods:

72 patients with dislocations of IOL are operated at the age of 52,7 years. In 51 eyes considerable shift of the upper edge of IOL down to an optical axis of an eye visually was defined, in 21 it was displaced below it. All operations were performed in various clinics over: the complicated cataract – 35 eyes, age – 22, traumatic – 10 and congenital – 5.Operations were performed in terms: from 1 month to 1 year – 29 operations, from 2 to 10 years – 36, from 11 to 26 – 7.

Results:

In 30 eyes removal of IOL with its reimplantation and TSF, in 3 cases removal of IOL without reimplantation from – for low visual functions as a result of a keratopathy – 2, a far-advanced stage of glaucoma– 1 is carried out. In 12 eyes reconstruction of a forward piece was required, in 11 the discission of a secondary cataract and in 2 – a trabeculectomy is carried out. In 31 cases transcleral fixation of IOL sulcus of "ab externo" on 3 and 9 hours, in 6 cases of TSF at 12 o'clock for the top gaptika of IOL is made. During surgical treatment centration of IOL in the back camera is received. In all cases visual acuity increase was noted.

Conclusions:

The dislocation of IOL demands elaboration of the correct tactics taking into account model of the dislocated IOL, an adequate assessment of the remains of a capsular bag, associated complications. Adequate surgical tactics allows to receive good anatomical and functional results.
