Purpose: 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. Case Report: 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 with a scleral fixated IOL. Conclusion: Rapid and severe anterior capsular contraction following cataract surgery is rare but appears to be associated with rod-cone dystrophy.

Iol Dislocation

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 areas where facilities are limited, as IOL dislocation could occur and requires immediate treatment to achieve a better result.

Abstract Background: Intraocular lens (IOL) dislocation is a rare but serious postoperative complication of intraocular lens implantation, so far, there is no report describing late intraocular lens dislocation caused by a deformed haptic piercing through the iris. Case report: A 29-year-old male developed IOL dislocation one and a half years after IOL implantation in his right eye. The eye examination showed that haptic pierced the iris at 10 o'clock in his right eye, according to intraoperative exploration, the haptic was deformed and became less elastic, the patient underwent the surgery of IOL reposition for various factors, but finally did not achieve a satisfactory outcome. Conclusion: Late IOL dislocation followed by haptic deformation is difficult to detect unless there are serious complications. When the position of IOL haptics is not in a plane with its optical surface, it should be highly vigilant that the function of the haptics may be abnormal. IOL replacement should be performed as soon as possible for the IOL dislocation caused by the loss of haptic tension.

Objective. The aim of this study was to evaluate possible risk factors for late intraocular lens (IOL) dislocation after routine cataract surgery. Material and Methods. A retrospective analysis of medical records of all the patients who were treated in the university hospital between 2011 and 2012 for late IOL dislocation requiring surgical management after routine cataract surgery was performed. In total, 58 patients (58 eyes) were included into the study. Results. The mean time between cataract surgery and late IOL dislocation was 67.8 months (SD, 34.9). A negative correlation was found between the patient age at cataract surgery and the time between cataract surgery and IOL dislocation (r=–0.29; P=0.042). Late in-the-bag dislocation occurred in 87.9% and late out-of-the-bag dislocation in 12.1% of the cases. Pseudoexfoliation was present in 56.9% and 42.9% of the eyes with in-the-bag and out-of-the-bag dislocation, respectively. The odds ratio for IOL dislocation within 43 months after complicated cataract surgery was 24.0 (95% confidence interval [95% CI] 4.5–127.4; P<0.001) and for in-the-bag IOL dislocation 24.9 (95% CI, 4.2–148.0; P<0.001). The odds ratio for in-the-bag IOL dislocation within 43 months after advanced cataract surgery was 18.8 (95% CI, 2.0–180.0; P=0.011). Moreover, in-the-bag IOL dislocation occurred earlier in the patients with past uveitis (P=0.020) or zonule laxity (P=0.037). Conclusions. Complicated cataract surgery increased the risk of both late in-the-bag and out-ofthe- bag IOL dislocation, and advanced cataract increased the risk of late in-the-bag IOL dislocation. The time to in-the-bag IOL dislocation shortens with pseudoexfoliation syndrome, advanced age, or past uveitis. These factors must be taken into account while planning a postoperative follow-up.

AIM: To describe a technique of managing intraocular lens (IOL) with deep dislocation in the vitreous cavity by performing pars plana vitrectomy (PPV) with only one pars plana incision under the direct illumination of the surgical microscope. METHODS: Patients who had in-the-bag or out-of-the-bag (spontaneous) IOL dislocation after uneventful phacoemulsification cataract extractions, with the dislocated IOL or IOL-capsular bag complex dropping completely into the vitreous since 2013 were included in our studies. The postoperative patients were followed up for 6mo. Detailed description of technique and retrospective description of eight typical cases were demonstrated in this study. RESULTS: A total of 40 surgeries were conducted using this technique. The main possible predisposing conditions included: post-vitrectomy, posterior capsule rupture or broken zonules, a history of ocular trauma, long axial length, secondary IOL implantation, chronic uveitis, retinitis pigmentosa and post-glaucoma surgery. In all eyes, the IOLs were successfully removed. No intraoperative or postoperative complications related to the procedures occurred. The preoperative corrected distance visual acuity (CDVA) ranged from 20/133 to 20/25, and at 6mo postoperatively, the CDVA was similar or the same. The intraocular pressure was all within the normal range. CONCLUSION: One-port PPV under direct vision with microscope illumination is a simple and safe surgical technique to managing IOL dislocation, which shortens the surgical time, and largely avoids surgical complications.

AbstractWe aimed to investigate the efficacy and safety of primary retropupillary iris claw intraocular lens (R-IOL) implantation in patients with complete intraocular lens (IOL) dislocation. In this single-center retrospective case series, we reviewed the medical records of patients who underwent R-IOL implantation surgery with pars plana vitrectomy for the treatment of IOL dislocation between September 2014 and July 2019. The primary outcome was change in visual acuity (VA) up to 24 months postoperatively. The secondary outcomes included changes in intraocular pressure (IOP), refractive errors, and endothelial cell count (ECC) over the same period. Data of 103 eyes (98 patients) were analyzed. The mean uncorrected VA was significantly improved at one month postoperatively (− 0.69 logMAR, P < 0.001), compared to the preoperative value. IOP (− 2.3 mmHg, P = 0.008) and ECC (− 333.4 cells/mm2, P = 0.027) significantly decreased one month post-surgery and remained stable thereafter. Postoperative mean spherical equivalents were similar to the prediction error throughout the follow-up period. IOP elevation (n = 8, 7.8%), cystoid macular edema (n = 4, 3.9%), and dislocation of the R-IOL (n = 10, 9.7%) were managed successfully. Overall, primary R-IOL implantation with pars plana vitrectomy is effective and safe for correcting IOL dislocation due to various causes.

Purpose. To investigate the clinical characteristics of patients with intraocular lens (IOL) dislocation after IOL implantation in Chinese Han populations. Methods. The medical records of patients with IOL dislocation were retrospectively reviewed from January 2007 to December 2017, and a total of 312 patients (male: 231, female: 97) (328 eyes) were included in this study. The axial length (AL), IOL power, and the time interval between cataract surgery and IOL dislocation as well as the ocular conditions associated with IOL dislocation were recorded. The IOL dislocation was classified and graded based on its relationship with the capsule and the position of the dislocated IOL. Results. The mean time between original cataract surgery and IOL dislocation was 5.63 ± 5.13 years; IOL dislocation occurred in up to 56.1% (184 eyes) of the eyes within 5 years. Trauma was found in 136 eyes (41.5%); pars plana vitrectomies were performed in 61 eyes (18.6%), and high myopia was detected in 108 eyes (32.9%). A total of 243 eyes (74.1%) had out-of-the-bag IOL dislocations, while 85 eyes (25.9%) had in-the-bag IOL dislocations. There was a statistically significant difference in the constituent ratio of trauma between in-the-bag dislocation and out-of-the-bag dislocation (Pearson’s chi2 = 33.3992, P<0.001); ocular blunt traumas were significantly higher in in-the-bag dislocations, while open-globe injuries were significantly higher in out-of-the-bag dislocations. A statistically significant difference was found for the ratio of patients with AL longer than 30 mm between in-the-bag dislocation and out-of-the-bag dislocation (Pearson’s chi2 = 9.7355, P<0.002). Conclusions. In Chinese Han populations, the most common IOL dislocation is out-of-the-bag dislocation; the most common risk factors were trauma, long axial length, and eyes undergoing pars plana vitrectomy; a minimum follow-up of 5 years is suggested for IOL dislocation-predisposed eyes undergoing cataract surgery.

BackgroundTo assess the influence of intraocular lens (IOL) characteristics on IOL dislocations after cataract surgery.MethodsPatients who underwent cataract surgery at the Department of Ophthalmology Graz, Austria, between 1996 and 2017 were included and medical records were reviewed. Cox proportional-hazard regression models were used to assess the influence of IOL characteristics on IOL dislocation.ResultsFrom 68 199 eyes out of 46 632 patients (60.2% women, mean age: 73.71 SD±10.82 years), 111 (0.16%) had an in-the-bag (ITB) disloaction and 35 (0.05%) had an out-of-the-bag (OTB) dislocation. The HRs adjusted for predisposing factors significantly associated with a higher risk for an ITB dislocation were 2.35 (95% CI, 1.45 to 3.8) for hydrophilic IOLs, 2.01 for quadripode IOLs (95% CI, 1.04 to 3.86) and 1.61 (95% CI, 1.04 to 2.48) for haptic angulation. A lower risk was observed for three-piece IOLs (HR=0.58, 95% CI, 0.34 to 0.98) and larger overall IOL diameter (HR=0.79, 95% CI, 0.66 to 0.95). For an OTB dislocation, the HR associated with a higher risk was 18.81 (95% CI, 5.84 to 60.58) for silicone IOLs and 2.12 (95% CI, 0.62 to 7.29) for hydrophilic IOLs. Larger overall IOL diameter (HR 0.40, 95% CI; 0.25 to 0.63) showed a lower risk.ConclusionHydrophilic IOLs, quadripode IOLs and haptic angulation were associated with a higher risk for an ITB dislocation, whereas three-piece IOLs and a larger overall diameter were associated with a lower risk. Risk factors for OTB dislocation were silicone IOLs, hydrophilic IOLs and a smaller overall IOL diameter.

Introduction: Spontaneous intraocular lens (IOL) dislocation is a rare, but serious, complication following cataract surgery. Case Report: We report a case of patient with a remote history of cataract surgery presenting to the emergency department with monocular blurred vision. Ocular point-of-care ultrasound (POCUS) facilitated diagnosis of a late spontaneous IOL dislocation. Discussion: Prosthetic IOL dislocations are being reported with increasing frequency. Prompt recognition of IOL dislocation is essential to prevent secondary complications, including acute angle-closure glaucoma and retinal detachment, which can result in permanent vision loss. Conclusion: Point-of-care ultrasound is a rapid, noninvasive imaging modality for early detection of IOL dislocation to help guide management, improve patient outcomes, and mitigate long-term sequelae.

Intraocular lens (IOL) dislocation is an unusual but serious complication after cataract surgery. We are here to report a rare case which is nontraumatic IOL dislocated and prolapsed into the anterior chamber in a retinitis pigmentosa (RP) patient. Zonular weakness and capsular contraction are considered to be the main contributing factors of IOL dislocation in RP patients. Patients at risk should be recognized and managed accordingly intraoperatively or postoperatively.
