3. Crystalline lens dislocation secondary to bacterial endogenous endophthalmitis (PubMed)

Crystalline lens dislocation secondary to bacterial endogenous endophthalmitis To present an unusual case of endogenous endophthalmitis secondary to Group A streptococcus (GAS) that resulted in dislocation of the crystalline lens.An immunocompetent 51-year-old man presented to the emergency room (ER) with upper respiratory infection (URI) symptoms and painful right eye. He was diagnosed with URI and viral conjunctivitis and discharged on oral azithromycin and polytrim eyedrops. He returned (...) a combination of anterior segment scarring, posterior segment damage, and hypotony. Interestingly, head computed tomography (CT) at the initial ER presentation showed normal lens position, but repeat CT at re-presentation revealed posterior dislocation of the lens.Endophthalmitis secondary to GAS has been sparsely reported in the literature, and this case highlights a unique clinical presentation. We suspect that this atypical non-hemolytic strain may have evaded detection on initial pharyngeal cultures

5. Repositioning a posteriorly dislocated silicone plate-haptic toric intraocular lens. (PubMed)

Repositioning a posteriorly dislocated silicone plate-haptic toric intraocular lens. We describe a technique for repositioning an encapsulated, posteriorly dislocated silicone plate-haptic toric intraocular lens (IOL) while preventing further dislocation into the vitreous cavity. Sutures of 10-0 polypropylene were used to ensure safe retrieval of the dislocated IOL. An anterior vitrectomy was then performed to remove the contracted capsular bag around the IOL. The IOL fixation hole (...) was temporarily externalized to allow quick and secure IOL fixation, eliminating the risk for losing the slippery silicone IOL into the vitreous cavity. Using this technique, the IOL was successfully placed in the proper position and resulted in good vision for the patient while avoiding the trauma of lens exchange.Copyright © 2018 ASCRS and ESCRS.

6. Cost-effectiveness analysis in a randomized trial of late in-the-bag intraocular lens dislocation surgery: repositioning versus exchange. (PubMed)

Cost-effectiveness analysis in a randomized trial of late in-the-bag intraocular lens dislocation surgery: repositioning versus exchange. To compare the cost-effectiveness of two operation methods for late in-the-bag intraocular lens (IOL) dislocation.In this randomized clinical trial, 104 patients were randomly assigned to IOL repositioning by scleral suturing (n = 54) or IOL exchange with a retropupillary iris-claw lens (n = 50). A cost-effectiveness analysis (CEA) was performed (...) 9.5 min shorter operation time for exchange.Repositioning tended to be more cost-effective than exchange; however, this is modified if also considering the operation time. Overall, it seems the cost-effectiveness is not alone sufficiently different to recommend one of the operation methods over the other for late in-the-bag IOL dislocation.© 2019 Acta Ophthalmologica Scandinavica Foundation.

9. Monocular lens dislocation due to vomiting-a case report. (PubMed)

Monocular lens dislocation due to vomiting-a case report. Lens dislocation is a common disease in ophthalmology, which leads to vision loss, while the lens dislocation caused by vomiting has not been reported yet. We report a case of lens dislocation caused by simple vomiting. This case further implicated for the pathogenesis of lens dislocation.A 51-year-old male who complained about "dizziness, vomiting, and the vision decreased for 4 h in right eye", after the eye examination, he was been (...) diagnosed with "lens dislocation induced by simply vomiting ". Surgery was performed successfully.We highlight the pathogenesis and development of the lens dislocation in this rare condition.Lens dislocation could be induced by simple vomitting, which increased the vitrous cavity presure to shock the zonular fiber and push the lens into the anterior chamber.

10. High-vacuum clothesline technique for elevation and repositioning of posteriorly dislocated intraocular lens. (PubMed)

High-vacuum clothesline technique for elevation and repositioning of posteriorly dislocated intraocular lens. We describe a technique to simplify the retrieval process of an intraocular lens (IOL) that has fallen into the posterior segment of the eye. A high-vacuum level setting is used to achieve fixation of the IOL to the vitrectomy tip, permitting the IOL to be elevated into the anterior segment. The clothesline technique is then used to secure the IOL partially within the anterior chamber (...) for subsequent suture fixation or explantation. This technique simplifies the elevation, repositioning, and/or explantation of a posteriorly dislocated IOL and eliminates the need to perform more complex and potentially traumatic maneuvers.Copyright © 2018 ASCRS and ESCRS.

13. Rapid Capsular Contraction with Secondary Intraocular Lens Dislocation Associated with Unspecified Rod-Cone Dystrophy: A Case Report (PubMed)

Rapid Capsular Contraction with Secondary Intraocular Lens Dislocation Associated with Unspecified Rod-Cone Dystrophy: A Case Report We report an unusual case of rapid and severe anterior capsular contraction associated with secondary intraocular lens (IOL) dislocation following cataract surgery in a patient with unspecified rod-cone dystrophy.A 68-year-old woman with a history of uncharacterized bilateral rod-cone dystrophy presented with blurry vision 1 month after cataract surgery. Best (...) corrected visual acuity was 20/40 in the operative eye. Slit-lamp exam showed severe anterior capsular phimosis limiting view of the fundus. Our patient underwent 2 sessions of Nd:YAG anterior capsulotomy with limited success. Limited anterior vitrectomy was then performed without success due to densely adherent capsular tissue to the anterior surface of the IOL and additional secondary IOL dislocation. She ultimately underwent pars plana vitrectomy, removal of the capsular bag, and IOL exchange

14. Intraocular Lens Dislocation after Cataract Surgery in Tambolaka, Southwest Sumba, Indonesia: A Case Report (PubMed)

Intraocular Lens Dislocation after Cataract Surgery in Tambolaka, Southwest Sumba, Indonesia: A Case Report Intraocular lens (IOL) dislocation is a rare complication of cataract extraction requiring prompt surgery. This case report aims to raise awareness of such cases and the importance of post-surgery follow-up. A 58-year-old female patient was found with anterior IOL dislocation a week after phacoemulsification surgery in her right eye. Visual acuity of the right eye was 1/60 with ciliary (...) injection and IOL dislocation to the anterior chamber of the right eye. The patient underwent surgery of the right eye and the IOL haptic was found to be broken. In this case report, the factors affecting IOL dislocation are axis length, broken IOL haptic, and patient activity that increased intraocular pressure. Cataract extraction surgery, although common, needs to be conducted carefully, and it is important for ophthalmologists and general practitioners to detect this condition, especially in rural

17. Clinicopathologic Correlation of Lens Epithelial Metaplasia and Late Intraocular Lens Dislocation After Repair of Retinal Detachment. (PubMed)

Clinicopathologic Correlation of Lens Epithelial Metaplasia and Late Intraocular Lens Dislocation After Repair of Retinal Detachment. In-the-bag intraocular lens dislocation is an uncommon but serious complication of cataract surgery in patients with previous repair of retinal detachment. The causative mechanism is currently unknown. We report histologic findings from a retrospective case series from 1993 to 2010 and suggest a possible mechanism to explain this association.Clinical (...) characteristics of 8 patients presenting with in-the-bag intraocular lens dislocation after repair of retinal detachment were evaluated. Explanted capsular bags from 3 of these patients were compared with pathologic changes of crystalline lenses associated with retinal detachment. Histologic examination of the explanted capsular bags revealed a paucicellular membrane that covered the concertina-like folded surface of the lens capsule. The lens capsule was devoid of epithelial cell nuclei and showed excessive

Astigmatism and Refractive Outcome After Late In-The-Bag Intraocular Lens Dislocation Surgery: A Randomized Clinical Trial. To compare surgically induced astigmatism (SIA) and refractive outcomes between two operation methods for late in-the-bag IOL dislocation.In this prospective, randomized, parallel-group clinical trial, 104 patients (eyes) were assigned to IOL repositioning by scleral suturing 1.5- to 2-mm posterior to limbus (n = 54) or IOL exchange with a retropupillar iris-claw IOL using (...) ). Mean postoperative spherical equivalent was -1.6 ± 1.6 D after IOL repositioning and -0.5 ± 1.0 D after IOL exchange (P < 0.001). For IOL repositioning, this represented a mean myopic shift of -0.7 ± 1.1 D compared with before the IOL dislocation (P < 0.001). For IOL exchange, it was within ±1 D of target refraction in 83% of the patients.Surgically induced astigmatism was modest in both operation groups, albeit with a tendency of being more pronounced for IOL exchange.
