This patient had a phakic IOL placed many years ago for the treatment of a high degree of axial myopia. This PRL (phakic refractive lens) helped to address the myopia for many years but the patient has now developed a cataract. The phakic IOL needs to be explanted and then the cataract surgery performed. How do you adjust the IOL power calculations for an eye with a phakic IOL? Also if this patient is younger and without a PVD (posterior vitreous detachment) does that increase the retinal detachment and retinal break risks? Answers in the video.
