The patient is a 78-year-old female who presented with progressive bilateral vision loss. Her corrected visual acuity was 20/100 in the right eye and 20/30 in the left eye. Ophthalmic examination of the right eye revealed changes in the anterior capsule of the lens.Lamellar Splitting, with nuclear cataract.
