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 58-year-old female patient from Tambolaka, Southwest Sumba, Indonesia presented for a follow-up after mass cataract extraction surgery. She graduated from high school and lives as a farmer. Before undergoing mass cataract extraction surgery, she complained of blurred vision in both eyes for 1 year. Upon examination, best visual acuity after correction was 1/300 for the right eye and 1/60 for the left eye. There was no history of other ocular disease prior to surgery. The patient was diagnosed with bilateral mature senile cataract. She then underwent phacoemulsification surgery of her right eye on August 27, 2016 in a mass cataract surgery in the hospital using a regular foldable lens. One week after the surgical procedure, the patient came to the hospital for post-surgery checkup and complained of sudden blurred vision in her right eye. History of eye trauma was denied by the patient. She admitted that before the symptoms appeared, she had often carried heavy loads around 5–10 kg and drawn water from wells as her daily activities. Upon physical examination, blood pressure was 130/90 mm Hg and visual acuity of the affected right eye was 1/60. Ciliary injection was found in the right eye along with IOL in the anterior chamber (Fig. ). Another surgery was later performed on the patient to replace the dislocated IOL with a new one. During the second operation, the trailing haptic was found to be broken. Post-surgery visual acuity of the right eye was 6/21.
