Reasons for Explantations of Posterior Chamber Phakic Intraocular Lenses in 1,490 Eyes.

To investigate the reasons for the removal and/or exchange of posterior chamber phakic intraocular lenses (PCPIOLs) and the outcomes of these procedures. In this retrospective study, PCPIOL implantations performed between January 2015 and June 2023 in a single center were reviewed. The study group consisted of the files of eyes with removed and/or exchanged PCPIOL. Visual acuities, refraction errors, endothelial cell counts, and measurements of the vault before and after exchanges were recorded. Reasons for removal and/or exchange were evaluated. The tuck-and-pull technique was used in all explantations. Twenty-three of 1,490 eyes with PCPIOL implantation required removal and/or exchange. Of the explanted eyes, 17 were implanted with PCPIOLs for myopia (1.21% of all myopic corrections) and 6 were implanted with PCPIOLs for hyperopia (6.59% of all hyperopic corrections). The most common reason for removal and/or exchanges after implantation was inappropriate vault (10 of the 23 total removals and/or exchanges), followed by cataract development (7 of the 23 total removals and/or exchanges). A comparison of the biometric characteristics of eyes with PCPIOL removal and/or exchange due to inappropriate vault with other PCPIOL implantations showed that anterior chamber depth, PCPIOL length, and white-to-white distance were significantly higher in the group of explanted eyes (P < .05). All eyes with high vault in myopic patients had a 13.2- or 13.7-mm length PCPIOL. The main reason for PCPIOL removal and/or exchange is vault values outside the ideal limits and cataract development. Before ordering 13.2- and 13.7-mm long PCPIOLs, biometric data of both eyes and recommended PCPIOL sizes should be carefully reviewed. [J Refract Surg. 2024;40(11):e797-e803.].

Post-Cataract Surgery Fungal Endophthalmitis: 6-Year Experience in Management and Outcomes at a Tertiary Eye Care Center.

This study aimed to describe the functional and anatomical outcomes of post-cataract surgery fungal endophthalmitis at King Khaled Eye Specialist Hospital (KKESH). A retrospective analysis of clinical data from a single institution was performed. This study included 29 patients with post-cataract surgery endophthalmitis with suspected or confirmed fungal etiology who presented between January 1, 2017, and December 31, 2022. We evaluated demographics, clinical features, microbiological assessments, and treatment strategies. The effects of various treatments on outcomes were analyzed. The need for additional treatment and functional and anatomical outcomes was also investigated. The mean time from surgery to the onset of ocular symptoms was 52.1 (SD ± 59.9; range, 3-210) days, and the mean time from surgery to the first visit to KKESH was 81.4 (SD ± 103.5; range, 2-510) days. Low culture positivity was noted in four samples, with two revealing Aspergillus sp. and two revealing Cladosporium sp. Of the 29 patients, 6 underwent pars plana vitrectomy (PPV) and received intravitreal antimicrobial/antibiotic injections. Two of the six patients also underwent simultaneous intraocular lens removal. The average number of additional treatments, regardless of visual acuity, was lower in the PPV group than in the conservative group (0.5 [SD ± 1.1; range, 0-3] and 1.48 [SD ± 1.47; range, 0-6], respectively). In the PPV group, 50% (n=3) of the eyes achieved functional success and 83.3% (n=5) of the eyes achieved anatomical success. In contrast, in the conservative group, 43.5% (n=10) of the eyes achieved functional success and 69.6% (n=16) of the eyes achieved anatomical success. For post-cataract surgery fungal endophthalmitis, a high index of suspicion and prompt PPV with empirical administration of intravitreal antifungal agents are required to achieve a favorable prognosis.

Risk factors for early and late retinal detachment after boston type I keratoprosthesis surgery.

To determine the differential risk factors for retinal detachment (RD) after Boston Type 1 Keratoprosthesis (B1KPro) during the first year after surgery (early RD; ERD) and afterwards (late RD; LRD). Retrospective cohort study of 94 eyes (90 patients) undergoing B1KPro implantation at Centro de Oftalmología Barraquer from June 2006 to July 2022 with a minimum follow-up of one year. The incidence of RD in the whole sample after B1KPro implantation was 29% (27/94), occurring in 21% of eyes (ERD; 20/94) the first year, and in 7% afterwards (LRD; 7/94). Hypotony was revealed as a significant risk factor for ERD (16/19 = 84%; OR = 14.5, P < 0.0001), together with aphakia (16/20 = 80%; OR = 5.9, P = 0.004), intraocular lens (IOL) removal (4/8 = 50%; OR = 6.2, P = 0.03), previous choroidal detachment (CD; 7/20 = 35%; OR = 35.5, P = 0.001) and previous pars plana vitrectomy (PPV; 15/20 = 75%; OR = 6.6, P = 0.006). Multivariate analysis included hypotony and PPV at any time as variables significantly associated with ERD occurrence. The occurrence of LRD was significantly related to peripheral retinal changes, detected few days before (4/6 = 66%; OR = 65, P < 0.0001). Hypotony emerged as one of the main factors influencing ERD occurrence after B1KPro implantation. Additionally, previous CD, PPV, aphakia, and IOL removal should be considered to estimate the risk of postoperative retinal detachment. In contrast, peripheral retinal changes after B1KPro seem to be significantly related to LRD occurrence. This study reinforces the need for frequent intraocular pressure evaluation, and comprehensive periodic retinal assessment over time. What is known Retinal detachment (RD) is a severe complication after Boston Type 1 Keratoprosthesis (B1KPro) implantation, resulting in a permanent reduction of visual acuity in a clinically relevant percentage of eyes. The time of RD occurrence after B1KPro implantation differs in the literature but is reported to be more common within the first year. Previous aphakia, choroidal detachment, or RD repair, intraocular lens removal, vitritis, or history of Nd-YAG laser have been described as risk factors for RD after B1KPro surgery in samples with varying follow-ups. Multivariate analysis in the first year after B1KPro surgery showed hypotony and pars plana vitrectomy at any time as significant risk factors for early RD. Late RD cases, occurring after one year following the B1KPro surgery, seem to be significantly related to peripheral retinal changes suffered a few days before loss of visual acuity and RD diagnosis. It is plausible to think that risk factors for RD after B1KPro differ in short and long postoperative times.

Comparison of Pacman cutting technique and trisection cutting technique for hydrophobic acrylic intraocular lens removal.

The objective of this retrospective cohort study is to compare the Pacman cutting technique with the trisection cutting technique for hydrophobic acrylic intraocular lens extraction. A total of 29 eyes of 29 patients requiring IOL removal were selected and enrolled in this study. The patients in group 1 (13 cases) underwent the conventional trisection cut technique from May 2022 to Dec. 2022. The patients in group 2 (16 cases) underwent the modified partial IOL cutting technique (Pacman cutting technique) from Jan. 2023 to June 2023. Corneal endothelial cells (CECs) count, slit-lamp examination, and intraocular pressure (IOP) measurement were conducted at all preoperative and postoperative visits. Surgical time, intraoperative and postoperative complications were recorded. The mean surgical time was 3.48 ± 1.54 minutes (range: 2 to 7 minutes) for the trisection cut technique group and 2.52 ± 1.18 minutes (range: 2 to 5 minutes) for the Pacman cut technique group. There was a statistically significant difference between the two groups in terms of surgical duration (P < .05). There was no difference in the mean preoperative CEC counts (group 1: 1924 ± 462, group 2: 1876 ± 516, P > 0.05). However, three months after the operation, the count of CECs decreased by 213 ± 72 (11%) in group 1 and 142 ± 57 (8%) in group 2. The decrease in CECs in group 1 was greater than that in group 2, and the difference was statistically significant (P < .05). There were no serious complications affecting vision in either group during the follow-up period. This study showed that the Pacman cutting technique is more effective and safer than the trisection cutting technique for hydrophobic acrylic IOL removal.

Direct Intraocular Lens Extraction Using a Newly Developed Lens-Grabbing Forceps.

Background: Due to lower age thresholds for cataract surgery and increased longevity, cases with intraocular lens (IOL) dislocation requiring removal have increased. Traditional methods, such as cutting or folding the IOL within the eye, pose a high risk of complications, including corneal endothelial and iris damage. Methods: We developed a new minimally invasive technique for direct IOL removal using specially designed lens-grabbing forceps. These forceps can grasp and remove the IOL through a small incision in a single motion, significantly reducing intraocular manipulations compared to conventional methods. Results: In our test cases, IOL removal through a 2.2 mm corneal incision was completed in approximately 95 s, with minimal incision enlargement (about 0.16 mm) and a slight decrease in corneal endothelial cells. Conclusions: Our findings suggest that this technique is minimally invasive and safe for IOL removal, offering a promising alternative to existing methods.

Repositioned versus exchanged flanged intraocular lens fixation for intraocular lens dislocation

This study aimed to compare the outcomes of flanged intraocular lens (IOL) fixation with new IOL exchange after dislocated IOL removal and repositioned dislocated IOL in patients with IOL dislocation. Eighty-nine eyes that underwent flanged IOL fixation were retrospectively included, with 51 eyes in the exchanged IOL group and 38 eyes in the repositioned IOL group. In both groups, best-corrected visual acuity (BCVA) improved at 1, 3, 6, and 12 months postoperatively and did not differ between the two groups at any of these time points. However, at 1 week postoperatively, BCVA in the repositioned IOL group improved compared with baseline, whereas that in the exchanged IOL group did not. Moreover, there were lesser changes in the corneal endothelial cell density (ECD) and corneal astigmatism in the repositioned IOL group than in the exchanged IOL group. The IOL positions, including IOL tilt and IOL decentration, were not different between the groups. Flanged IOL fixation with new IOL exchange and with repositioned dislocated IOL for patients with IOL dislocation had similar visual outcomes and IOL position. However, the latter had a smaller corneal ECD decrease and astigmatic change. This technique was effective in treating IOL dislocation while minimizing corneal injury.

Anterior Segment Optical Coherence Tomography in Uveitis-Glaucoma-Hyphema Syndrome

ABSTRACT Purpose Uveitis-Glaucoma-Hyphema (UGH) syndrome results from contact between the intraocular lens (IOL) and the iris or ciliary body, leading to uveal structure erosion and blood-aqueous barrier breakdown. Treatment involves various drugs, with IOL removal often being necessary. Diagnosis relies on clinical signs, but imaging techniques like ultrasound biomicroscopy (UBM) or anterior segment optical coherence tomography (AS-OCT) are crucial. AS-OCT accurately depicts IOL position and potential contact, emerging as a primary alternative to UBM in the diagnosis. Our study aimed to correlate AS-OCT findings with clinically detectable iris atrophy in pseudophakic patients with IOL-iris chafing and UGH syndrome. Methods The study retrospectively analyzed patients diagnosed with UGH syndrome presenting at the Ocular Immunology Unit of Reggio Emilia, Italy, from January 2019 to August 2023. Patients’ data were collected. Ophthalmological exams and imaging were performed. The peephole sign in AS-OCT images was evaluated. Statistical analyses were conducted, with a significance level of p ≤ 0.05. Results The study reviewed 22 eyes of 22 patients with UGH syndrome. Four eyes were excluded, leaving 18 patients (8 females, 10 males). Common misdiagnoses included idiopathic anterior uveitis (55.5%) and herpetic anterior uveitis (16.7%). All patients had iris transillumination defects, mostly focal (77.8%). AS-OCT revealed IOL chafing in all the eyes, with peephole sign correlation. More peephole signs occurred with IOL in the sulcus (p-value = 0.08). Conclusion The study recommends AS-OCT for UGH syndrome confirmation and UBM when IOL-iris chafing is not observed on AS-OCT scans.

Comparison of the Residual Amount of an Ophthalmic Viscosurgical Device Among Different Types of Intraocular Lens Implants in vitro.

Although ophthalmic viscosurgical devices are quite important for safe cataract surgery, currently, postoperative residual ophthalmic viscosurgical devices can cause various complications. Previously, we developed a method to visualize residual ophthalmic viscosurgical devices after irrigation/aspiration in vitro and found that the amount of residual ophthalmic viscosurgical device on a single-piece intraocular lens was greater than that on a three-piece intraocular lens. In the present study, we compared the amounts of residual ophthalmic viscosurgical device among various foldable intraocular lenses to investigate the factors that determine the quantity of residual ophthalmic viscosurgical device. Simulated cataract surgery was performed in pig eyes using an ophthalmic viscosurgical device labeled with fluorescent silica particles. After the simulated surgery procedure, the fluorescent silica attached to the intraocular lens was observed and quantified by inductively coupled plasma-atomic emission spectrometry after intraocular lens removal. The amount of residual ophthalmic viscosurgical device was compared among five representative single-piece intraocular lenses and one three-piece intraocular lens. The distribution and amount of the residual ophthalmic viscosurgical device differed for each intraocular lens. The amount of silicon in the lens capsule differed among the intraocular lens types. The postoperative residual tendency of ophthalmic viscosurgical devices differed among various single-piece intraocular lenses. The behavior of the intraocular lenses within the capsule affected the residual tendency. The removal of ophthalmic viscosurgical device in the lens capsule should be tailored for each intraocular lens to improve efficiency.

Clinical Factors, Treatment Selection, and Outcomes in Postcataract Fungal Endophthalmitis from Contaminated Viscoelastics

To investigate the factors associated with treatment outcomes of postcataract surgery fungal endophthalmitis outbreaks related to contaminated viscoelastics. Retrospective analysis of clinical data from multiple institutions. This study included 228 eyes of 210 patients who were diagnosed with postcataract surgery fungal endophthalmitis related to the use of viscoelastic material (Unial, Unimed Pharmaceutical Inc); they were followed up for 6 months after the diagnosis. Clinical features and causative species were identified and treatment outcomes were analyzed in patients who underwent 6 months of follow-up. Propensity score matching was conducted to elucidate the impact of vitrectomy timing and intraocular lens (IOL) removal on treatment outcomes. Clinical factors and selection of treatment modalities associated with treatment outcomes at 6 months. Baseline visual acuity (P < 0.01), age (P= 0.05), and the presence of corneal edema (P < 0.01) were closely associated with poor best-corrected visual acuity (BCVA) at 6 months. Patients who underwent immediate vitrectomy after diagnosis showed significantly better BCVA at 6 months (mean logarithm of minimum angle of resolution 0.26 ± 0.43 vs. 0.52 ± 0.52, P= 0.03) and greater degree of visual improvement (mean-0.17 ± 0.37 improvement vs. 0.10 ± 0.57 deterioration, P= 0.03) than those who underwent deferred vitrectomy. Patients who underwent IOL removal during vitrectomy required a lower number of intravitreal antifungal agent injections (mean 8.9 ± 9.1 vs. 16.7 ± 12.2, P < 0.01) and showed a lower incidence of repeated vitrectomy (20% vs. 82%, P<0.01) than in those without IOL removal. In postcataract fungal endophthalmitis, prompt vitrectomy at the time of diagnosis resulted in better treatment outcomes, and IOL removal reduced the treatment burden. Prompt and aggressive surgicalintervention should be considered for postcataract fungal endophthalmitis.

Transient band keratopathy associated with epithelial ingrowth treated with antimetabolites

Introduction: To report a case of visually significant band keratopathy associated with ocular inflammation in the setting of epithelial ingrowth, both of which resolved after repeated antimetabolite treatments. Patient and Clinical Findings: A 74-year-old woman with a history of uveitis–glaucoma–hyphema syndrome after complicated cataract surgery presented with epithelial ingrowth in the right eye and diffuse central band keratopathy after posterior chamber intraocular lens (IOL) removal and pars plana vitrectomy and anterior chamber IOL placement. Diagnosis, Intervention, and Outcomes: After multiple intraocular injections of antimetabolites, the epithelial ingrowth and visually significant band keratopathy resolved. Conclusions: Treating the underlying source of inflammation, such as epithelial ingrowth with antimetabolites, was associated with clearance of the band keratopathy without further intervention.

Results of Scanning Electron Microscopy of an Explanted Hydrophilic Acrylic IOL with Hydrophobic Coating

This article presents a clinical case of intraocular lens (IOL) removal due to surface degeneration 2 years after implantation. Explantation was performed resulting from clinically significant clouding of the IOL and decreased visual acuity. The microscopic picture and microtopography of the explanted hydrophilic acrylic IOL with hydrophobic coating were studied using scanning electron microscopy. The opacities were total, located on the entire surface of the lens, including the supporting elements.

Changes in Intraocular Lens Explantation Indications and Comparison of Various Explantation Techniques

To examine the current causes of intraocular lens (IOL) explantation, compare various IOL explantation techniques, and assess the visual outcomes and complications. Retrospective comparative case series. A total of 175 eyes of 160 patients who underwent IOL exchange for a one-piece foldable acrylic IOL between January 2010 and March 2022 were covered by the research. Group 1 included 74 eyes from 69 patients in which the IOL was removed after being grasped, pulled, and refolded inside the main incision. Group 2 consisted of 66 eyes from 60 patients in which the IOL was removed by bisecting it, whereas group 3 included 35 eyes from 31 patients in which the IOL was removed by enlarging the main incision. Surgical indications, interventions, visual outcomes and refraction, and complications. The mean patient age was 66.1 ± 10.5 years. The mean time between primary surgery and IOL explantation was 57.0 ± 38.9 months. IOL dislocation (in 85 eyes, 49.5%) was the most common reason for IOL explantation. When the patients were examined in terms of both surgical indication groups and IOL removal techniques, corrected-distance visual acuity increased significantly in all subgroups (P < .001). The increase in astigmatism after surgery was 0.08 ± 0.13 diopters (D) in group 1, 0.09 ± 0.17 D in group 2, and 0.83 ± 0.29 D in group 3 (P < .001). The grasp, pull, and refold technique for IOL explantation provides a simpler surgery, less complication, and good visual outcomes.

Was it Leuconostoc species? A case of delayed-onset endophthalmitis presenting 14 years after cataract surgery.

To report a case of delayed-onset endophthalmitis presenting 14 years after uncomplicated cataract surgery. Case report. An 89 year-old pseudophakic man complained of redness and reduced visual acuity in his right eye. He had no history of trauma or systemic infection, and his only surgery on the right eye was an uncomplicated cataract surgery 14 years prior. On physical exam, he was found to have keratic precipitates and a white posterior capsular plaque in the right eye. He was treated with a right pars plana vitrectomy and intraocular lens removal. Microbiological classification of the samples revealed the presence of a Leuconostoc species within the vitreous humor and coagulase negative Staphylococci on the lens. Two months following placement of the intraocular lens, he achieved a best corrected visual acuity of 20/200 in his right eye. To our knowledge, this is the first reported case of delayed-onset endophthalmitis occurring more then 10 years following an uncomplicated cataract surgery. This case highlights a highly unusual presentation of delayed-onset endophthalmitis, and reports a potential novel microbiological cause of plaque formation.

Delayed onset Cutibacterium (formerly Propionibecterium) acnes endophthalmitis triggered by intravitreal steroid injection.

We report a case of delayed onset Cutibacterium acnes (C. acnes, formerly Propionibacterium acnes or P. acnes) endophthalmitis with onset triggered by intravitreal steroid (triamcinolone acetonide; TA) injection in a pseudophakic patient, 7 years after cataract surgery.Methods/Patients: A 67 years old, male presented with gradual worsening of vision, eye redness and photosensitivity that started a month after intravitreal TA injection (Triescience, 4mg/0.1mL, Alcon Labs, Fort Worth, TX) for cystoid macular edema secondary to branch retinal vein occlusion in the right eye. Patient had undergone cataract surgery with intraocular lens (IOL) in that eye 7 years prior. Exam showed visual acuity of counting fingers at 3 feet, conjunctival injection, with 2+ anterior chamber cell and 2+ vitreous haze. Uveitis work up including Angiotensin converting enzyme (ACE), Quantiferon Gold, and syphilis IgG screen was negative. Diagnostic pars plana vitrectomy (PPV) with intravitreal injection of antibiotics was performed and vitreous sample was sent for detailed laboratory analysis. Vitreous fluid analysis was positive for C. acnes and negative for viral, fungal and malignant cells. Although the patient received intravitreal antibiotics injection twice, the intraocular infection and inflammation persisted which eventually required an IOL and capsular bag removal, followed by insertion of a secondary IOL later. Delayed onset C. acnes endophthalmitis may be triggered by an intravitreal steroid injection in pseudophakic patients.

Postoperative Exogenous Endophthalmitis Caused By Escherichia Coli: a Rare Case Report and Literature Review

We report a rare case of postoperative endophthalmitis caused by Escherichia coli. The diagnosis of postoperative endophthalmitis in our patient was established based on the clinical signs of hypopyon along with vitritis. The patient underwent pars plana vitrectomy, anterior chamber washout, intraocular lens removal, and intravitreal antibiotics (amikacin and vancomycin) injection. The culture of both the vitreous sample and the intraocular lens, revealed a heavy growth of Escherichia coli. Escherichia coli is an unusual microorganism to cause postoperative endophthalmitis. A major breach in the sterilization may explain this infection. Proper sterilization and prophylactic measures are crucial to avoid this disastrous complication.

Recurrent Uveitis-Glaucoma-Hyphema Syndrome Due to Positional Pupillary Capture after Sutureless Scleral-Fixated Secondary Intraocular Lens Placement

Here, we present a case of floppy iris leading to positional pupillary capture by a sutureless, scleral-fixated intraocular lens (IOL) causing recurrent uveitis-glaucoma-hyphema (UGH) syndrome. The patient developed recurrent episodes of UGH syndrome after dislocated IOL removal and the placement of sutureless, scleral-fixated IOL. Gravitationally dependent pupillary capture was noted with the superior iris moving in front of and behind the IOL, depending on head positioning. Ultrasonography showed a floppy iris that moved with shifting gaze. The lack of the capsular bag may have contributed to extreme iris movements. This finding may be secondary to a combination of a lack of zonular support and capsular bag support as well as the lack of vitreous support following vitrectomy. When possible, secondary IOL placement behind a peripherally preserved capsular bag may reduce the risk of UGH.

Combined Temporary Pupilloplasty and DSEK in an Eye With a Hydrophilic Acrylic Intraocular Lens to Prevent Opacification: A Case Report.

The aim of this study was to describe a case of temporary pupilloplasty during Descemet stripping endothelial keratoplasty to prevent opacification of a hydrophilic acrylic intraocular lens (IOL). A 60-year-old man presented with corneal edema in the left eye after a traumatic cataract removal and scleral suture fixation of a hydrophilic acrylic IOL (Akreos, Bausch + Lomb, Bridgewater, NJ). Descemet stripping endothelial keratoplasty with temporary pupilloplasty was performed. The pupilloplasty was lysed with neodymium:YAG laser on postoperative day 5 after the air bubble was no longer present. At 1 year after surgery, the patient did not develop IOL opacification despite the intracameral air used during the surgery. Opacification of hydrophilic acrylic lenses is a visually significant complication of intracameral gas from endothelial keratoplasty. Our case demonstrates the potential to prevent IOL opacification in a patient with a hydrophilic acrylic IOL by using temporary pupilloplasty.

The silent beast – a case of late‐onset postoperative endophalmitis

AbstractLate‐onset postoperative cataract surgery endophthalmitis remains a rare but sight‐threatening complication usually caused by slow‐growing pathogenic agents: bacterial or fungus. The delayed diagnosis and the potential irreversible ocular damage make this condition a challenging case for ophthalmologists.Herein, we present a 71‐year‐old woman with late‐onset fungal endophthalmitis after cataract surgery caused by candida parapsilopsis, a rare etiologic agent. This diagnosis should be taken into consideration in every late‐onset postoperative persistent panuveitis with no response to antibiotics and partial response to topical steroids, even after negative vitreous or tap culture. White deposits on the surface of the intraocular lens or the capsule are a crucial sign. Systemic and intraocular antifungal therapy along with vitrectomy and intraocular lens removal—if necessary—are the main therapy to ensure the best visual prognosis.

Modified adaptation of the twist-and-out technique for intraocular lens exchange.

Many methods can be used to explant an intraocular lens (IOL) after prior cataract surgery. Here, we describe a modified approach to the twist-and-out technique for IOL removal. The IOL is dissected and brought into the anterior chamber (AC), where 1 haptic is externalized. The adaptation in this technique occurs next; an additional paracentesis is made 180 degrees away from an adjacent side port, and the shaft of a 25-gauge cannula is threaded across the AC to connect these incisions. This maneuver frees both hands to use forceps within the incision, grasp the IOL, and rotate it around the forceps. The use of both hands allows for a smaller, more controlled movement than the original 1-handed pronation. The cannula shaft aids in twisting the IOL tightly around the forceps while protecting the corneal endothelium. The forceps-lens complex is then withdrawn, extracting the IOL whole with 1 efficient movement.

Six Cases of Fungal Exogenous Endophthalmitis after Cataract Surgery

Purpose: To report six cases of exogenous fungal endophthalmitis developed after cataract surgery.Case summary: Over about 1 month, eight patients were referred to our hospital under suspicion of fungal endophthalmitis arose after cataract surgery. We performed vitrectomy and intraocular lens removal. We intraoperatively sampled the anterior chamber, vitreous cavity, or intraocular lens surface, and performed staining and culture tests. Before the culture test results were available, we commenced empirical treatment under suspicion of fungal endophthalmitis (based on the clinical features). Five eyes were male and three female (eight eyes of eight patients); the mean patient age was 64 years. The time from cataract surgery to the commencement of appropriate treatment ranged from 13 to 36 days (average 28 days). The culture tests revealed Fusarium species in six of the eight patients. At the 1-month postoperative follow-up of these six patients, the best-corrected visual acuities were 20/20 (one eye), 20/40 (two eyes), 20/50 (one eye), and 20/100 (two eyes).Conclusions: Fungal endophthalmitis is very rare after cataract surgery but is associated with poor visual prognosis and requires long-term treatment. If fungal endophthalmitis is suspected, aggressive treatment with an appropriate selection of medication is important.
