A 71-year-old male presented with decreased visual acuity in the left eye for 2-month duration. On ocular examination, the best-corrected visual acuity in the right and left eyes was 20/20 (MR−, +0.50Ds -0.50Dc Ax90) and 20/60 (MR-error), respectively. On slit lamp examination, an empty capsular bag with anterior continuous curvilinear capsulorhexis (CCC) was found in the anterior chamber []. In addition, the slit lamp examination showed downward subluxation of a three-piece IOL and some vitreous strands in the anterior chamber in the mydriasis test []. The medical history of this patient was as follows. In 2009, he was diagnosed with a senile cataract (posterior subcapsular opacity type) in both eyes and underwent cataract surgery on both eyes in our clinic. There was no zonular weakness or pseudoexfoliation in the crystalline lens on the preoperative examination. The cataract surgery consisted of one-stitch, a 2.8-mm temporal clear corneal incision, phacoemulsification, and implantation of a three-piece hydrophobic acrylic IOL (TECNIS ZA9003, Abbott Medical Optics, Santa Ana, CA, USA) in the left eye and a one-piece hydrophobic acrylic IOL (TECNIS ZCB00, Abbott Medical Optics, Santa Ana, CA, USA) in the right eye. He denied accidental trauma before or after the cataract surgery. He also had no hereditary genetic diseases, including Marfan syndrome, homocystinuria, spherophakia, and retinitis pigmentosa. However, he stated that he had a habit of rubbing his eyes.\nThree years postoperatively, he presented with decreased visual acuity in the left eye and anterior dislocation of the capsular bag. The IOL was dislocated into the posterior chamber. We planned to reposition the IOL with scleral fixation of the existing lens. The dislocated capsular bag was extracted from the anterior chamber and spread on the corneal surface, and we observed a partial circumferential laceration along the equator of the capsular bag; that is, at the junction of the anterior and posterior capsular bags. The bag had an intact margin of anterior capsular curvilinear capsulorhexis [Fig. and ]. To reposition the IOL, two partial-thickness, limbal-based scleral flaps were created about 1.5 mm from the limbus, under which sclerotomies were performed. The IOL was repositioned through two 1-mm side punctures made using two 23-gauge end-gripping micro-capsulorhexis forceps (Micro Surgical Technology, Redmond, WA, USA), and both haptics were externalized under the scleral flap with Colibri forceps. The haptic ends were tucked into intralamellar scleral tunnels made with a 26-gauge needle. The scleral flaps and conjunctiva were closed with fibrin glue (Tisseel; Baxter, Deerfield, IL, USA; []). The surgery was completed with an anterior vitrectomy. This method, called a glued intrascleral fixation of the posterior chamber of the IOL, was introduced by Kumar et al.[] The uncorrected visual acuity recovered to 20/30 in the left eye [].
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.
