Neoplastic transformation of cells is characterized by karyotypic abnormalities involving aneuploidy, quantitative changes, as well as multiple clonal rearrangements of the number and structure of chromosomes. It is probable that chromosomes are one of the mechanisms of cells immortalization and transformation. Despite many years of study of chromosomal rearrangements, data on primary chromosomal rearrangements in early stages of transformation is still insufficient.

Besides 14 patients (19 eyes) 1-2 years after cataract phacoemulsification with IOL implantation were examined. All patients underwent routine ophthalmological examination and tonography.

It has been revealed that the cells have a polyploidy karyotype with 96-112 chromosomes and multiple numerical and structural clonal rearrangements. Almost all the chromosomes of the karyotype are involved in structural rearrangements.
