Abstract:
Surgical treatment of intraocular lens (IOL) with late dislocation remains one of the current problems of ophthalmology.
Purpose:
To evaluate specific morphofunctional changes in the eye after dislocated IOL exchange with retropupillary-fixated iris-claw IOL.
Material And Methods:
Surgical outcomes of 150 patients (150 eyes) with in-the-bag IOL dislocation (122 eyes) or sulcus-fixated IOL dislocation (28 eyes) were analyzed. The follow-up period was 1-3 years.
Results:
Increase in visual acuity and stable retropupillary fixation of the IOL was observed in all cases after reimplantation. Mean endothelial cell loss after 3 months was 6.9±1.3% in the group with preoperative density of >1200 cells/mm2 and 12.3±2.7% in the group with preoperative density of <1200 cells/mm2. There was no significant increase in intraocular pressure after IOL reimplantation. The incidence of clinical cystoid macular edema with decreased visual acuity was 4.7%, which is significantly more frequent than in patients after uncomplicated phacoemulsification with in-the-bag IOL implantation.
Conclusion:
Retropupillary implantation of iris-claw IOL provides stable fixation, good functional outcomes with low complication rates and is suitable for reimplantation in eyes without adequate capsular support.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
