    Cataract/Anterior Segment, Retina/Vitreous

    : A 48-year-old diabetic man presented with sudden worsening of vision in the right eye following intravitreal injection of ranibizumab for diabetic macular edema. His best corrected vision in the right eye was 20/200, and the anterior segment showed a posterior subcapsular cataract with a needle track in the posterior capsule (Figure 1). Lens injury has sometimes been seen as a complication after an intravitreal injection. Iatrogenic cataract following an intravitreal injection has an incidence of 0.44%--0.6% and is usually attributable to direct injury with the injection needle. Lenticular touch, cataract formation, dislocation of the lens, and zonular tears can occur. Improper technique, inexperience of the surgeon, or patient's head movement at the time of the injection are possible causes. Careful preoperative planning and attention to fluidics, low bottle height, hydrodelineation without hydrodissection, avoidance of nuclear rotation, and use of a dispersive ophthalmic viscosurgical device to tamponade the vitreous allow safe phacoemulsification with posterior chamber intraocular lens implantation that can avoid these complications.
