A 40-year-old otherwise healthy male with a history of closed globe injury to his left eye 25 years back (9131 days ago, on September 10, 1996) on examination showed a rosette [Figure 1]a that was embedded deep in the lens substance [Figure 1]b 786 microns behind the anterior capsule on anterior segment optical coherence tomography [Figure 1]c. The usual location of the traumatic rosette[1] was anterior subcapsular. Fresh lenticular fibers formed from the anterior epithelium during the same time course pushed the opacity 786 microns posteriorly. We calculated the rate of lens growth in this patient to be 86.08 nm/day or 0.03144 mm/year by using phakochronology.[2]
