GLISTENING INSIDE INTRAOCULAR LENSES
Abstract
Cataract phacoemulsification with intraocular lens implantation (IOL) is the most common method of cataract treatment. One of the complications associated with the loss of IOL transparency and deterioration of visual functions is the formation of microvacuoles (10-20 µm) filled with liquid in the lens. This process is called glistening. The article presents the main causes of glistening: temperature fluctuations during the production or storage of IOLs; water absorption by the material due to the incompleteness of the implant polymerization process; the difference in osmotic pressure between the cavities in the material itself and the liquid in which the IOL is located after implantation. The negative effect of this complication on visual acuity and retinal contrast sensitivity is described. A promising direction to prevent glistening is the search for new materials used for the production of IOLs.
