It was determined that the refractive shift towards myopia with underlying baseline hyperopia in these cases was not due to errors in calculating the IOL optical power. The cause of ineffective IOL positioning and myopization was the formation of blocks: in the first case - a vitreo-pseudophakic block due to anterior displacement of the pseudophakic diaphragm, and in the second case - a capsular block.
