A 63-year-old male with history of retinal detachment and remote history of bilateral cataract surgery presented to the ED with blurry vision in his right eye. He described sudden-onset visual disturbance “like a curtain dropping” while walking earlier in the day. His vision transiently improved with bending over but would blur again when he stood upright. He denied any ocular trauma, eye pain or swelling, discharge, headache, or other focal neurological complaints. His past medical history included coronary artery disease, diabetes mellitus, hyperlipidemia, and hypertension.\nOn physical exam, pupils were equal and reactive to light bilaterally. Extraocular movements were intact. Visual acuity was 20/100 in the right eye and 20/30 in the left eye. Slit lamp exam of the right eye revealed a deep, quiet anterior chamber, but a lack of pupillary reflection and inability to visualize the retina.\nPoint-of-care ultrasound of the affected eye was performed in the sagittal and transverse anatomic planes using a high-frequency linear transducer. The prosthetic lens was visualized in the posterior chamber with the temporal side haptic still adherent to the lens capsule consistent with an IOL dislocation (, ), whereas an appropriately positioned prosthetic lens would appear as a hyperechoic curvilinear structure within the lens capsule posterior to the iris. The patient was then asked to perform the six cardinal positions of gaze to maximize visualization of the ocular structures. There was no evidence of retinal detachment, vitreous detachment, or vitreous hemorrhage. The case was discussed with his ophthalmologist, and the patient underwent urgent operative repair of the dislocated lens as an outpatient.
A 49-year-old Caucasian male presented with a dense right-sided cortical cataract in 2007 at the age of 44. HIV infection was diagnosed in 1997. His ocular history included bilateral keratoconus, bilateral uveitis, and multifocal choroiditis, which had been treated with eight intravitreal triamcinolone (IVTA) injections previously and was quiescent at the time of his cataract surgery. His right eye vision was 3/60 preoperatively. He underwent uncomplicated phacoemulsification cataract surgery and implantation of a 15.5D Alcon SN60WF into the bag. Postoperatively, his acuity improved to 6/12. Subsequently, he underwent right eye vitrectomy for long-standing vitritis in 2008. Seventy-five months after his initial PCIOL implant, he represented with visual loss in the right eye due to an in-bag IOL dislocation. He underwent a pars plana vitrectomy and removal of IOL. He was left aphakic and managed with a hard contact lens. On the last review in June 2014, his right eye corrected visual acuity was 6/7.5.
