—A healthy 43-year-old woman presented with difficulty in reading of 6 months' duration. Visual acuity was 20/20, J5 OD and 20/20, J4 OS. Cycloplegic refraction did not reveal any hyperopia. Near visual acuity was J4 OD and J5 OS, improving to J1 OU with an addition of +1.5 diopters (D) OD and +2.0 D OS.The patient's medical history and evaluation were unremarkable.
