Preventing the Argentinian flag sign and managing anterior capsular tears: A review.

The Argentinian flag sign (AFS) is a feared complication during cataract extraction. Intralenticular pressures, especially excessive posterior pressure, have been identified as potential mechanisms for capsular stress and tearing associated with AFS. Capsular tension is created by positive intralenticular pressures, which cause the irido-lens diaphragm to move anteriorly once the manual capsulorhexis has been initiated. This tension can cause inadvertent tears that self-propagate to the lens equator, causing an AFS, among other intraoperative complications. Thus, this review highlights the importance of identifying intumescent cataracts as well as a combination of techniques to relieve intracapsular pressures needed to prevent AFS. However, some instances of anterior capsular tears are unavoidable. Therefore, focus will also be placed on techniques during cataract extraction used to manage anterior capsular tears, mitigating extension to the posterior capsule.

Síndrome de contracción capsular bilateral / Bilateral capsule contraction syndrome

El síndrome de contracción capsular se describe como una reducción progresiva y acelerada del diámetro de la capsulorrexis y del saco capsular tras la extracción extracapsular del cristalino. Se reporta el caso de una paciente femenina, con antecedentes de miopía elevada, a quien se le realizó cirugía de catarata de ambos ojos sin complicaciones transquirúrgicas, y regresa con síndrome de contracción capsular bilateral al mes de operada. Se comenta la conducta seguida en ambos ojos(AU)

Capsule contraction syndrome is described as progressive, accelerated reduction in capsulorhexis and capsular bag diameter after extracapsular crystalline lens extraction. A case is presented of a female patient with a history of high myopia who underwent cataract surgery of both eyes without any intraoperative complication. One month after surgery the patient presents with bilateral capsule contraction syndrome. Comments are made on the clinical management of each eye(AU)

Achieving successful capsulorhexis in intumescent white mature cataracts to prevent Argentinian flag sign - A new multifaceted approach to meet the challenge.

Purpose: To present a case series of intumescent white cataract cases managed by a new surgical technique to attain a single stage Continuous Curvilinear Capsulorhexis (CCC). Methods: The series included 60 eyes of 60 patients with white cataract which underwent preoperative anterior chamber depth, lens thickness and ultrasonographic A-scan for intralenticular spikes. A partial size main port (~1.8mm) is created as the first entry into the anterior chamber (AC). A 30-gauge needle of insulin syringe entered through a limbal stab incision is used to decompress the anterior and posterior intralenticular compartments. Following which a standard size, one stage capsulorhexis was performed in a trypan blue stained capsule using microcapsulorhexis forceps entered through the partial sized trapezoidal main port. The main port was secondarily enlarged for phacoemulsification. Results: Based on the intraoperative findings, 43 eyes were categorized as Intumescent type-1 cataracts i.e., with presence of actual liquefied cortex aspirated using 30-gauge needle and 17 eyes as Intumescent type-2 cataracts, i.e., presence of swollen lens without any obvious liquefied cortex. Standard size, circular and centred CCC was achieved in 100% of the cases and no Argentinean flag sign was noted. Surgeon perceived raised intralenticular pressure in 41% of the cases in type-1 subset and 61% cases in type-2 subset (P-0.06). Posterior capsular plaque was observed in 22% of the cases, adherent cortex in 25% and anterior capsular plaque in 5% of the cases. At 6weeks follow up 92% patients had best corrected visual acuity of 20/40 or better. Conclusion: A multi-layered approach can help in attaining successful CCC in cases of white mature cataract with high intralenticular pressure.

The effects of functionally monocular patients' emotional reactions during phacoemulsification under topical anesthesia / A influência das reações emocionais durante a facoemulsificação com anestesia tópica em pacientes de olho único

ABSTRACT Purpose: To evaluate the relationship between the incidence of complications and functionally monocular patients' emotional reactions during phacoemulsification under topical anesthesia. Methods: We enrolled 22 functionally monocular patients (11 males and 11 females; group 1) and 19 age- and sex-matched controls (6 males and 13 females; group 2) in this prospective, interventional, cross-sectional, case control study. Demographics data, including age, sex, and educational background, were collected. Surgeries were performed by the same surgeon, and during surgery, the patients' vital signs (blood pressure and heart rate) and surgical events (duration, body movements, signs of increased vitreous cavity pressure, difficulty in performing capsulorhexis, and complications) were noted. Pre- and postoperative visual acuity was also analyzed. Results: The mean age of group 1 was 73.05 ± 13.31 years and of group 1 was 69.74 ± 16.81 years. There was no significant between-group difference in systolic and diastolic blood pressures. The average heart rate was similar in both groups, too. During surgery, the surgeon's perception of excessive eye, eyelid, or head movements in both groups was similar, in addition to signs of increased vitreous cavity pressure. Conclusion: It is safe to perform phacoemulsification under topical anesthesia in functionally monocular patients, who apparently behave similarly to binocular patients.(AU)

RESUMO Objetivo: Avaliar a relação entre a incidência de complicações e reações emocionais durante a cirurgia de catarata sob anestesia tópica em pacientes funcionalmente monoculares. Métodos: Estudo prospectivo, transversal, caso-controle de vinte e dois pacientes monoculares e dezenove controles pareados por idade e sexo . Dados demográficos foram analisados: idade, sexo e escolaridade. As cirurgias foram realizadas pelo mesmo cirurgião e durante o procedimento os sinais vitais dos pacientes (como pressão arterial sistêmica e frequência cardíaca) e eventos cirúrgicos (duração da cirurgia, movimentos corporais, sinais de aumento da pressão vítrea, dificuldade de realização da capsulorrexis e complicações) foram coletados. A acuidade visual pré e pós foi analisada. A distribuição normal dos dados foi confirmada com o teste de Shapiro-Wilk. Os dados foram expressos como média ± DP e porcentagem. A comparação dos diferentes testes clínicos entre os grupos foi realizada utilizando Student's t-test e ANOVA com correção de Bonferroni. O qui-quadrado foi usado para comparar dados demográficos. Valor de p<0,05 foi considerado estatisticamente significante. Resultados: Este estudo incluiu vinte e dois olhos de 22 pacientes funcionalmente monoculares (6 homens e 13 mulheres) e dezenove olhos de 19 controles (11 homens e 11 mulheres). A média de idade foi de 73,05 ± 13,31 anos nos indivíduos monoculares e 69,74 ± 16,81 no controle. Considerando-se os sinais vitais não houve diferença significativa entre os grupos (p>0,05). Durante o procedimento, a percepção do cirurgião em relação aos movimentos excessivos de olho, pálpebra ou cabeça em ambos os grupos foi semelhante, assim como sinais de aumento da pressão vítrea (p=0,2 e p=0,1, respectivamente). Conclusão: Este estudo sugere que é seguro realizar a extração de catarata com anestesia tópica em pacientes funcionalmente monoculares. Esses pacientes aparentemente se comportam de maneira semelhante aos pacientes binoculares.(AU)

Sewing needle microcapsulotomy to avert Argentinian flag sign.

The Argentinian flag sign is a known complication in intumescent white cataracts, which arises instantly after an initial prick with a sharp hypodermic needle on a stretched out anterior capsule. Increased intralenticular pressure is believed to be responsible for propagation of the initial prick into a radial capsular tear. However, it is the linear cut configuration of the initial prick, created by the hypodermic needle on the tense anterior capsule, which spontaneously opens up and propagates toward the periphery along its margins. To overcome this, a new instrument was devised, sewing needle microcapsulotome, to puncture the capsule and create a single or multiple round openings with smooth margins, allowing the bag to decompress satisfactorily without yielding to disruptive intralenticular forces. This technique of sewing needle microcapsulotomy, to prevent the Argentinian flag sign, was found to be highly effective and safe in a series of surgeries on intumescent cataracts.

Novel double-flanged technique for managing Marfan syndrome and microspherophakia.

A new technique for fixating the capsular bag in patients with ectopia lentis is presented. In this technique, the capsulorhexis is performed using a femtosecond laser, followed by the insertion of a standard capsular tension ring to redistribute capsular forces. The nucleus is hydroprolapsed into the anterior chamber and nuclear disassembly is performed above the iris plane to reduce zonular stress. Finally, a 5-0 polypropylene monofilament is used to fixate a capsular tension segment and subluxated capsular bag. This novel double-flanged method, achieved with cautery, does not require direct suturing of the monofilament on the sclera. This article describes the use of this new technique in 3 eyes, 2 in patients with Marfan syndrome and 1 in a patient with microspherophakia.

Pseudocapsulorrexis: desdoblamiento idiopático de la cápsula anterior del cristalino / Pseudocapsulorhexis: idiopathic split of the anterior lens capsule

Se presenta el caso de una mujer de 81 años que acude para valoración de cirugía de catarata en el ojo derecho. El examen biomicroscópico revela la existencia de una catarata C2N4 (Lens Opacities Classifi cation System, versión III) con una cápsula anterior que en su región central pareciera estar abierta a modo de capsulorrexis, aunque sin trasvase de material lenticular ni signos inflamatorios en cámara anterior Figura 1. Su consistencia y morfología nos hacen pensar en un posible desdoblamiento idiopático de la cristaloides anterior, ya que tanto el reborde pupilar como la gonioscopia son rigurosamente normales. De ahí nuestro título de "pseudocapsulorrexis".

The role of a femtosecond laser in congenital cataract associated with aniridia / O papel do laser de femtosegundo na catarata congênita associada à aniridia

ABSTRACT A patient with bilateral aniridia and progressive congenital cataract was treated at the age of 7 years through phacoaspiration with femtosecond laser capsulotomy, in-the-bag intraocular lens implantation, and pars plana vitrectomy (combined with posterior capsulotomy). The diameter of the planned anterior capsulotomy was 4.7 mm; however, due to elevated tension in the young capsular bag, the capsulotomy diameter increased (to around 6 mm) shortly after release of the tension by the laser. In addition, the patient had a very flat and small cornea, causing the formation of air bubbles in the curved laser interface. This was addressed by filling the gap by using a viscoelastic. A very similar situation was observed in both eyes. Use of the femtosecond laser facilitated a successful outcome in a complex congenital cataract case with a safe capsulotomy that ensured in-the-bag intraocular lens placement.

RESUMO Paciente com aniridia bilateral e catarata congê­nita progressiva foi tratado com a idade de 7 anos através de facoemulsificação com capsulotomia anterior por laser de femtosegundo, implante de lente intra-ocular e vitrectomia via pars plana (combinada com capsulotomia posterior). O diâmetro da capsulotomia anterior prevista foi de 4,7mm, porém, devido à elevada tensão do saco capsular jovem, o diâmetro da capsulotomia aumentou (para cerca de 6mm) logo após a liberação da tensão pelo laser. Além disso, o paciente tinha uma córnea muito plana e pequena, causando a formação de bolhas de ar na interface do laser. Isso foi resolvido preenchendo a lacuna usando um viscoelástico. Uma situação muito semelhante foi observada em ambos os olhos. O uso do laser de femtosegundo facilitou um resultado bem-sucedido em um caso complexo de catarata congênita com uma capsulotomia anterior segura que garantiu a colocação da lente intra-ocular dentro do saco capsular.

A multipronged approach to prevent Argentinian flag sign in intumescent cataracts.

In this communication, we describe a technique for creation of a single stage, adequately sized capsulorrhexis in intumescent cataracts by depressurizing the anterior and posterior intralenticular compartments in a nonleaky anterior chamber (AC) to prevent capsulorrhexis extension and Argentina flag sign. Initially, an incomplete main-port incision is made by the partial entry of a 2.2-mm keratome. A cohesive dispersive ophthalmic viscosurgical device (OVD) is injected into AC. Standard side-port incisions are made, followed by anterior capsular staining. The fluid cortex in anterior intralenticular compartment is aspirated by puncturing anterior capsule in the center using a 30-gauge needle entered through a separate limbal stab incision. The nucleus edge is gently tipped posteriorly with the needle tip to release the fluid from posterior intralenticular compartment also and as much fluid aspirated as possible. OVD is again injected and capsulorrhexis is performed in a single stage using micro-capsulorrhexis forceps.

Reverse Argentinean flag sign: Intraoperative complication during capsulorhexis.

We report a case of iatrogenic creation of an excessive anterior-to-posterior gradient in the setting of an open anterior capsule during capsulorhexis. This complication shows the inverse mechanism of that observed in the Argentinean flag sign. An excessive anterior-to-posterior gradient from an exuberant ophthalmic viscosurgical device fill of the anterior chamber caused radialization of the anterior capsule during creation of a continuous curvilinear capsulorhexis in a nonintumescent lens. We describe this complication as the reverse Argentinean flag sign.

Double-flanged-haptic and capsular tension ring or segment for sutureless fixation in zonular instability.

PURPOSE: This paper introduces a surgical technique for the sutureless management of zonular dialysis greater than 120° using a capsular tension segment (CTS) or a modified capsular tension ring (m-CTR; CTR with suturing eyelets) and a haptic removed from a 3-piece polypropylene IOL. METHODS: A CTR is used as normal. Cataract removal is followed by connection of the CTS or m-CTR to the single haptic and created using heat to make a flange in one haptic's extremity. The other extremity is placed in the CTS or m-CTR's central hole. The CTS or m-CTR/flanged-haptic complex is introduced into the capsular bag and aligned with the weakest zonular quadrant. A 30-gauge needle guides the externalization of the free haptic extremity through the adjacent pars plana and creates a flange on the second haptic tip permitting intrascleral fixation of the CTS or m-CTR. RESULTS: The result is a successful IOL implantation with a sutureless technique. CONCLUSIONS: This double-flanged m-CTR/CTS technique allows suture-free option for managing zonular weakness or dialysis while performing cataract surgery.

Posterior argentinean flag-like sign during primary posterior continuous curvilinear capsulorhexis.

We describe a unique complication during primary posterior continuous curvilinear capsulorhexis (PCCC) in a patient with megalocornea scheduled for phacoemulsification with toric multifocal intraocular lens (IOL) implantation. After nucleus emulsification and cortex removal, the capsular bag was filled with cohesive viscoelastic in preparation for PCCC to achieve reverse optic capture of the IOL, thus ensuring stability. However, as soon as the initial puncture was made using a 27-gauge needle to start the capsulotomy, the posterior capsule opening extended peripherally from 0º-180º. This capsule extension was similar to the Argentinean-flag sign in hypermature cataracts, and both are caused by excessive intracapsular pressure. Careful bimanual manipulation was performed to implant the IOL on the desired axis, which occurred uneventfully. At a postoperative visit, the patient exhibited excellent uncorrected visual acuity with a well-aligned IOL.

Posterior argentinean flag-like sign during primary posterior continuous curvilinear capsulorhexis / Sinal da bandeira argentina- like durante capsulorrexis posterior primária

ABSTRACT We describe a unique complication during primary posterior continuous curvilinear capsulorhexis (PCCC) in a patient with megalocornea scheduled for phacoemulsification with toric multifocal intraocular lens (IOL) implantation. After nucleus emulsification and cortex removal, the capsular bag was filled with cohesive viscoelastic in preparation for PCCC to achieve reverse optic capture of the IOL, thus ensuring stability. However, as soon as the initial puncture was made using a 27-gauge needle to start the capsulotomy, the posterior capsule opening extended peripherally from 0º-180º. This capsule extension was similar to the Argentinean-flag sign in hypermature cataracts, and both are caused by excessive intracapsular pressure. Careful bimanual manipulation was performed to implant the IOL on the desired axis, which occurred uneventfully. At a postoperative visit, the patient exhibited excellent uncorrected visual acuity with a well-aligned IOL.

RESUMO Os autores demonstram uma complicação durante a realização de uma capsulo tomia circular contínua posterior (CCCP) em um paciente com megalocórnea programado facoemulsificação com implante de lente intraocular (LIO) tórica multifocal. Após a remoção do núcleo e córtex, o saco capsular foi preenchido por viscoelástico coesivo com finalidade de prepará-lo para realização da CCCP e com isso assegurar o correto alinhamento do implante no eixo desejado. Entretanto, assim que a agulha de 27-gauge foi utilizada para confecção puntura inicial da capsulotomia, imediatamente a cápsula posterior se abriu até periferia de 0-180 graus, similar à lesão capsular vista no sinal da Bandeira Argentina em cataratas hipermaduras, ambos causados por pressão excessiva intracapsular. Manipulação cuidadosa foi realizada para implantação da lente no eixo correto, a qual aconteceu sem intercorrências. No pós-operatório, a paciente apresentou uma excelente acuidade visual sem correção com LIO corretamente alinhada no eixo desejado.

Avaliação da eficácia de um novo marcador cirúrgico para capsulorrexe anterior / Effectiveness evaluation of a new surgical marker for anterior capsulorhexis

RESUMO Objetivo: Avaliar a eficácia de um novo marcador cirúrgico para ajudar na confecção da capsulorrexe anterior analisando o seu dimensionamento e formato, comparando com a capsulorrexe confeccionada manualmente de maneira livre. Métodos: Como experimento, 3 residentes (R3) de Oftalmologia do Hospital Universitário Onofre Lopes (HUOL) e 1 oftalmologista em treinamento, voluntários, realizaram (cada um) 10 capsulorrexes em olhos de porco enucleados. Em 5 olhos foi utilizado o marcador e em outros 5, não. Todos os olhos foram fotografados tendo ao lado uma régua para orientar e calibrar um aplicativo para a avaliação morfométrica do procedimento. O diâmetro alvo foi de 5 mm, cujo perímetro correspondente é 15,7 mm e a área 19,652 mm2. Foram avaliados em cada procedimento: os diâmetros máximo, mínimo e médio, o perímetro, a área e o desvio em relação ao diâmetro e quanto ao aspecto ideal. Resultados: No grupo utilizando o marcador o diâmetro médio foi 5,44mm (±0,89) contra 6,37mm (±0,67) (p=0,001), no grupo no qual não se utilizou o marcador; quanto ao perímetro, 17,52mm (±1,92) no grupo utilizando o marcador contra 20,14mm (±2,09) (p<0,001) sem o marcador e quanto a área, 24,73mm2 (±1,92) com o marcador, contra 32,62mm2 (±6,32) (p<0,001), sem o marcador. Em relação ao aspecto da capsulorrexe 1,26mm (±0,12), contra 1,21mm (±0,7) (p=0,09) e em relação ao desvio de curvatura: 0,87 (±0,05), contra 0,9 (±0,04), (p=0,06) respectivamente. Conclusão: O trabalho mostrou que o marcador avaliado é eficaz para auxiliar a confecção da capsulorrexe conduzindo a resultados melhores que o método a mão livre.

ABSTRACT Purpose: To evaluate the effectiveness of a surgical device that intented to help in the preparation of the anterior capsulorhexis analyzing the design and shape, comparing with capsulorhexis made by free hand. Methods: Three ophthalmology residents(R3) at the HUOL and one surgeon in training, participate in this research as volunteers. Each surgeon perform 5 capsulorhexis in porcine eyes using the device, and five others by free hand as a control. All capsulorhexis were photographed having a ruler as reference to guide and calibrate a computer application for morphometric evaluation (Cambuí Labs, Natal, Brazil). All surgeons aimed to produce a circular continuous capsulorhexis of 5 mm diameter that represents 15,7mm in perimeter and 19,652mm2 in area. Each wet-lab capsulorhexis was evaluated in regard to these criteria: diameter (mean, maximum and minimum), perimeter, area, deviation from the ideal diameter and ideal shape. Results: Compare to control groups, capsulorhexis with the aid of the surgical device showed: 5,44mm ±0,89 vs 6,37mm ±0,67, for capsulorhexis diameter (p=0,001); 17,52mm ±1,92 vs 20,14mm ±2,09 for capsulorhexis perimeter (<0.001); 24,73mm2 ±1,92 vs 32,62mm2 ±6,36 for capsulorhexis area (p<0,001). A tendency for better result with the aid of the surgical device was observed for deviation of an ideal diameter or ideal aspect were appreciated: 0,87mm ±0,05 vs 0,9 ±0,04 for deviation of a curve (p=0,06); 1,26mm ±0,12 vs 1,21mm ±0,7 for the capsulorhexis aspect (p=0,09). Conclusion: Capsulorhexis produced with the aid of the surgical device, significantly improved wet-lab capsulorhexis performance.

Contracción capsular poscirugía de catarata en paciente con pseudoexfoliación / Capsular contraction after cataract surgery in a patient with pseudoexfoliation

La pseudoexfoliación es una alteración de la matriz extracelular fuertemente asociada a catarata y glaucoma secundario de ángulo abierto. Relacionada con la edad avanzada y más común en mujeres, es una enfermedad sistémica con típicas alteraciones en el ojo que hacen más difícil la cirugía, especialmente la debilidad zonular y la poca dilatación pupilar. Los pacientes con pseudoexfoliación operados de catarata, requieren un seguimiento posoperatorio más cuidadoso para detectar y tratar tempranamente las complicaciones posoperatorias como es la contracción capsular del caso que presentamos y que resolvió con tratamiento de Yag Láser en los bordes de la capsulorrexis(AU)

Pseudoexfoliation is an extracelular matrix alteration closely associated with cataract and secondary open angle glaucoma. Older age-related and more common in women, it is a systemic illness with typical alterations in the eye such as zonular weakness and little pupil dilation, which makes the surgery more difficult. The patients with pseudoexfoliation and caratact surgery require a more careful postoperative follow-up to early detect and to treat the postoperative complications such as the capsular contraction of the case reported in this paper, which was treated with Yag Laser in the capsulorhexis borders(AU)

Efficacy of Eyesi surgical simulator training in improving high-tension capsules capsulorhexis performance / Eficácia do treinamento com simulador cirúrgico Eyesi em melhorar a capsulorrexe em cápsulas de alta tensão

ABSTRACT Purpose: To evaluate if Eyesi cataract surgical simulator training using its standard course curriculum is effective in improving performance of cataract surgery trainees on creating capsulorhexis on high-tension capsules on the simulator. Methods: We retrospectively analyzed training reports of ophthalmic surgery trainees (2nd and 3rd year residents and cataract fellowship trainees) that have accomplished the standard Eyesi cataract surgery simulator training course version 2.1 between May 2012 and August 2013 at Instituto de Diagnostico e Terapia Ocular, Rio de Janeiro, Brazil. We compared the mean score (from 0 to 100) attributed by the simulator on performing the same task, a capsulorhexis on a high-tension capsule, on the surgical simulator "before training" (during beginning of the course) and "after training" (at later stages of the course). Results: Thirty-seven trainees' reports were analyzed. Mean and standard deviation "before training" high-tension capsulorhexis score was 41.73 ± 27.08 points and the mean "after training" score was 72.55 ± 16.40 points, a difference of +30.82 points (p value <0.001 on Paired t test), representing a 73% improvement on performance. Conclusions: Eyesi surgical simulator training on course version 2.1 curriculum was effective in improving performance of cataract surgery trainees on creating capsulorhexis on high-tension capsules.
