“…This technique allows for the rapid evacuation of liquid toward either the anterior or the vitreous chamber, which results in the quick resolution of CBS and IOL repositioning 23. Durak et al24 recommend performing anterior capsulotomy first, as this technique may be technically easier and safer than the posterior technique 24.…”

PurposeTo report the case of a patient who developed late capsular block syndrome and to review the current literature regarding this complication of phacoemulsification procedures.MethodsThe literature was reviewed to summarize the diagnosis, classification, use of diagnostic aids, and the current treatments for this complication.ResultsA 69-year-old patient complained of decreased visual acuity 11 months after undergoing phacoemulsification. She was found to have a secondary myopization. Anterior segment ultrabiomicroscopy confirmed the diagnosis of capsular block syndrome. The patient underwent neodymium-doped yttrium aluminum garnet (Nd:YAG) laser posterior capsulotomy, which resulted in complete resolution of her symptoms.ConclusionCapsular block syndrome is a fairly rare complication of phacoemulsification procedures that, depending primarily on the timing of its occurrence following surgery, can develop into one of the three following possible clinical scenarios: intraoperatory, early postoperatory, and late postoperatory. In this patient, Nd:YAG laser capsulotomy was shown to be a safe and effective treatment option for this type of complication.

“…Possible treatments in symptomatic patients of CBDS are Nd: YAG laser capsulotomy or surgical lysis of adhesions [12][13][14]. Nd:YAG posterior capsulotomy was performed in all the cases safely and yielded excellent visual results in all cases, with minimal biometric or refractive changes.…”

Background: To provide insights into the characteristic of ultra-late onset capsular bag distension syndrome (CBDS) after phacoemulsification. Design: An interventional, retrospective case series at a tertiary care institute. Participants: 5 Post-cataract surgery patients who presented with the retrolenticular fluid collection. Methods: This is an interventional, retrospective case series of 5 cases who presented with clinical signs of ultralate CBDS>7 years after uneventful phacoemulsification with in-the-bag posterior chamber intraocular lens implantation at a tertiary care institute. Scheimpflug imaging was used in all cases in addition to slit lamp biomicroscopic examination to assess and diagnose the condition. Neodymium:Yttrium Aluminium Garnet (Nd:YAG) posterior capsulotomy was performed in all to treat the condition. Main outcome measure: Results: All 5 patients presented with a milky fluid collection within the distended capsular bag without raised intraocular pressure or a shallow anterior chamber. Scheimpflug imaging confirmed the diagnosis in all cases and all eyes revealed a hyper-reflective space between the intraocular lens optic and the posterior capsule. Nd:YAG posterior capsulotomy was performed in all patients, with resolution of fluid and improvement of visual acuity. Conclusion: Our case series showed that Scheimpflug imaging is a useful modality to diagnose ultra-late onset CBDS and to differentiate this condition from intraocular lens opacification and posterior capsule opacification (PCO). Nd:YAG posterior capsulotomy proved to be successful treatment for ultra-late CBDS with no significant change in biometric or refractive parameters.

“…Recently, Nd:YAG laser treatment, including anterior and posterior laser capsulotomy, has been recommended as the major approach to cure late-onset CBS for its microinvasion and convenience [9, 14], while more and more authors are worried about the potential complications after posterior laser capsulotomy, such as vitreous floaters, cystoid macular edema, and retinal detachment [15–17]. Several reports of late-onset CBS have also been verified to be related to Propionibacterium acnes ; hence, after posterior laser capsulotomy, P. acnes -associated endophthalmitis may occur [10, 11, 18, 19].…”

Purpose To further investigate the pathogenesis of late-onset capsular block syndrome (CBS) and to evaluate the safety of surgical treatment. Methods Seven patients diagnosed with late-onset CBS were retrospectively analyzed. Anterior chamber depth (ACD), intraocular pressure (IOP), refractive diopter, and best-corrected visual acuity (BCVA) before and after surgery were recorded. The opaque substance was tested with Western blot, and a flow cytometer multiple array assay system was utilized to evaluate the levels of inflammatory cytokines from opaque substance and aqueous humor, respectively. Results Patients who had undergone surgical treatment showed a significant BCVA and spherical equivalent refractive error improvement (P = 0.002, P = 0.021, resp.). Nevertheless, ACD and IOP before and after surgery were in normal range with no difference (P = 0.165, P = 0.749, resp.). αB-crystallin and βB-crystallin were detected in all opaque substances. Tumor necrosis factor-alpha (TNF-α) and interlukin-1β (IL-1β) levels in opaque substance were significantly higher than those in aqueous humor (P = 0.038, P = 0.007, resp.), while IL-2 and IL-6 were not detected in any samples. Conclusions Opaque substance is derived from human lens epithelial cells. Inflammatory cytokines may be involved in the pathogenesis of late-onset CBS. In addition, surgical treatment is an effective approach. This trial is registered with ChiCTR-IOR-17011287.
