Visual rehabilitation after LASIK complication: flap amputation, topo-guided surgery, and phacoemulsification.

We present a case of a patient complaining of monocular diplopia due to a decentered ablation after LASIK. The patient underwent a wavefront-guided retreatment, which resulted in an epithelial ingrowth complication. Additionally, the patient developed cataract, with cataract surgery requiring reliable biometric measurements. Therefore, we opted for corneal treatment and corneal surface regularization. Although we attempted to lift the flap and wash the interface initially, the procedure proved unsuccessful, thereby necessitating immediate flap amputation. Once the corneal surface was regularized in the seventh postoperative month, transepithelial photorefractive keratectomy was successfully performed to homogenize the ocular surface, thereby significantly improving the patient's corrected visual acuity and resolving monocular diplopia. The surface and corneal curvature stabilized by the fifth month after the procedure. Phacoemulsification was then performed along with the implantation of a toric monofocal lens, which was selected using an appropriate formula, resulting in an excellent uncorrected visual acuity.

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.

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.

Evaluation of visual performance and patient satisfaction with pseudophakic monovision technique.

PURPOSE: To evaluate the distance, intermediate and near visual acuity of patients with bilateral cataract operated on both eyes corrected for distance in one eye and for near in the fellow eye, as well as, their stereo acuity and their general satisfaction. SETTINGS: Hospital de Olhos de São Paulo and Complexo Hospitalar Padre Bento - Guarulhos - São Paulo - Brazil. METHODS: This is a prospective study of 76 eyes of 38 patients with bilateral cataract aiming to become spectacle free after surgery. The patients were operated on both eyes; the first eye was corrected for distance and the fellow eye for near vision. The refractive error was programmed between -0.5 D and +0.5 D in the first eye and -2.00 D in the second eye. Patients with preoperative corneal astigmatism equal or higher than 1.0 D were excluded from the study. The uncorrected and best-corrected distant visual acuity (UCDVA, BCDVA) were tested, as well as the uncorrected near visual acuity (UCNVA) and collected at the 3 postoperative months. The Titmus test was performed at the last follow-up. Finally, the modified questionnaire VF-7 was applied and the patient was required to choose, regarding their general satisfaction, between very satisfied, satisfied, or unsatisfied. RESULTS: All patients achieved uncorrected distant visual acuity 20/40 or better (mean SE 0.625 D) and uncorrected near visual acuity J3 or better (mean SE -2.0 D), and intermediate visual acuity J3 in 90%. The Titmus test revealed an average of 197' of arc with reduction of stereo acuity in most of patients as expected and 97.3% of patients demonstrated to be satisfied or very satisfied with this technique. CONCLUSION: It consists in a viable technique for correction of near, intermediate and distant vision on cataract surgery as demonstrated by the high rate of satisfaction (97.3%) by the modified VF-7 questionnaire, especially when the patient has no access to a multifocal intraocular lens.

Fidelidade do "potential acuity meter" (PAM) no prognóstico da acuidade visual pós-operatória de cirurgia de catarata / Fidelity of the potential acuity meter in the postoperative visual acuity of cataract surgery

OBJETIVO: Avaliar a relação da acuidade visual (AV) obtida pelo "potential acuity meter" (PAM) no pré-operatório de cirurgia de catarata com a acuidade visual obtida no pós-operatório, bem como, sua correlação com a classificação morfológica dominante da catarata. MÉTODOS: Trata-se de um estudo prospectivo realizado no setor de Catarata do Centro de Estudos do Hospital Monumento envolvendo 63 olhos de 45 pacientes avaliados de julho a setembro de 2006, submetidos à cirurgia de catarata sob a técnica de facoemulsificação com implante de lente intra-ocular, sendo posteriormente excluído 1 olho. No período pré-operatório, foi realizado o PAM sob midríase e seu resultado foi comparado à melhor acuidade visual pós-operatória do terceiro mês e correlacionado com a classificação morfológica da catarata, sendo denominado satisfatório aquele resultado que não variou mais do que duas linhas na tabela de Snellen. RESULTADOS: A média de idade foi de 45,3 anos com média da acuidade visual obtida pelo PAM de 0,64 logMAR. No terceiro mês pós-operatório, a média da melhor acuidade visual corrigida (MAVC) foi de 0,09 logMAR. O PAM hiperestimou o resultado da MAVC em 8 olhos (13 por cento), hipoestimou em 41 olhos (66 por cento) e nos 13 olhos restantes (21 por cento), as acuidades foram idênticas. Este apresentou uma fidelidade inversamente proporcional à intensidade de opacidade do cristalino no caso da catarata nuclear (1+ com 75,5 por cento e 4+ com 33,3 por cento), entretanto esta acurácia foi maior nos casos de subcapsular posterior (85,7 por cento). CONCLUSÃO: O PAM hipoestimou ou manteve da acuidade visual na maioria dos casos (87 por cento). Apresentou uma fidelidade inversamente proporcional à intensidade de opacidade do cristalino no caso da catarata nuclear, 1+ com 75,5 por cento e 4+ com 33,3 por cento; entretanto esta acurácia foi maior nos casos de subcapsular posterior (85,7 por cento).

PURPOSE: To evaluate the correlation between the preoperative visual acuity (VA) obtained by the potential acuity meter (PAM) and the postoperative VA in a patient submitted to cataract surgery, as well as its correlation with the dominant morphologic classification of the cataract. METHODS: This is a prospective study performed at the Hospital Monumento Study Center. Sixty-three eyes of 45 patients submitted to phacoemulsification with intraocular lens implantation were enrolled in this study and 1 eye had been excluded. Besides the complete examination in the preoperative period, PAM was used and its results were compared with the VA at the third postoperative month and correlated with the dominant morphologic cataract classification. The result was called satisfactory when the variation was equal to or less than two lines at the Snellen chart. We transformed the AV into logMAR for comparison with the literature. RESULTS: The mean age was 45.3 years with a mean VA of 0.64 logMAR by the PAM. At the third postoperative month, the mean best corrected visual acuity (BCVA) was 0.09 logMAR. The PAM overestimated the BCVA in 8 eyes (13 percent), underestimated it in 41 eyes (66 percent) and in 13 eyes (21 percent) the BCVA were the same. The satisfactory results regarding nuclear cataract were reduced in cases of higher density (1+/4 with 75.5 percent e 4+/4 with 33.3 percent) and increased in the posterior subcapsular cataracts (85.7 percent). CONCLUSION: PAM revealed an underestimation or maintenance of the BCVA in most cases (87 percent). Its fidelity was inversely proportional in the nuclear cataracts (1+/4 with 75.5 percent e 4+/4 with 33.3 percent) and higher in the posterior subcapsular cataracts.

[Evaluation of the modified capsular tension ring in cases of traumatic lens subluxation]. / Avaliação do uso do anel endocapsular modificado em casos de subluxação traumática do cristalino.

PURPOSE: To evaluate the behavior of the modified capsular tension ring (MCTR) in traumatic subluxated cataracts analyzing the visual acuity, centration of the capsular bag, pseudophacodonesis, postoperative follow-up and intra- and postoperative complications. SETTING: Cincinnati Eye Institute, Cincinnati, Ohio, USA. METHODS: Twenty-two eyes of 22 patients with traumatic loss of zonular support had phacoemulsification using PCIOL and MCTR implantation. The preoperative examination included best correct visual acuity (BCVA) and the presence or absence of phacodonesis, lens decentration and vitreous prolapse. The postoperative evaluation included BCVA, the presence of pseudophacodonesis, PCIOL centration, necessity of vitrectomy and other complications. RESULTS: 21 eyes (95.45%) had an improvement in BCVA. The preoperative examination disclosed phacodonesis in 11 eyes (50%) and no eye presented pseudophacodonesis in the postoperative period. Preoperatively, symptomatic decentration was presented by 10 eyes (45.45%) and 22 eyes (100%) had no decentration after surgery. The preoperative examination revealed vitreous prolapse in the anterior chamber in 9 eyes (40.90%). Vitrectomy was required in 11 eyes (50%). CONCLUSIONS: The use of the MCTR resulted in a good centration of the capsular bag and the PC IOL in 22 eyes with traumatic cataract and loss of zonular support.

Avaliação do uso do anel endocapsular modificado em casos de subluxação traumática do cristalino / Evaluation of the modified capsular tension ring in cases of traumatic lens subluxation

OBJETIVO: Avaliar o comportamento do anel modificado de tensão capsular em cataratas traumáticas com subluxação, analisando a acuidade visual, centração do saco capsular, pseudofacodonese, seguimento pós-operatório, e complicações intra e pós-operatórias. LOCAL: Cincinnati Eye Institute, Cincinnati, Ohio, USA. MÉTODOS: Vinte e dois olhos de 22 pacientes com perda traumática de suporte zonular foram submetidos à facoemulsificação utilizando lente intra-ocular de câmara posterior e o implante do anel capsular modificado. O exame pré-operatório incluiu melhor acuidade visual corrigida (MAVC), a presença ou ausência de facodonese, descentração do cristalino e prolapso vítreo. A avaliação pós-operatória incluiu MAVC, presença de pseudofacodonese, centração do implante, necessidade de vitrectomia e outras complicações. RESULTADOS: Vinte e um olhos (95,45 por cento) tiveram melhora da MAVC. O exame pré-operatório revelou facodonese em 11 olhos (50 por cento) e nenhum olho apresentou pseudofacodonese. No exame pré-operatório, a descentração sintomática estava presente em 10 olhos (45,45 por cento). Todos os olhos apresentaram centração do complexo saco capsular/LIO no pós-operatório. Prolapso vítreo foi diagnosticado antes da cirurgia em 9 olhos (40,90 por cento) e a vitrectomia foi necessária em 11 olhos (50 por cento). CONCLUSÃO: O uso do anel modificado de tensão capsular resultou em boa centração do complexo saco capsular/lente intra-ocular nos olhos estudados com catarata traumática e perda de suporte zonular.

Unilateral dysphotopsia after bilateral intraocular lens implantation using the AR40e IOL model: case report.

The authors report a recent complication during the postoperative period of cataract surgery. A patient was submitted to cataract surgery in both eyes with IOL implantation (Sensar) inside the capsular bag. The postoperative period of right eye was uneventful, however, in the left eye the patient noted a dark shadow at the temporal visual field at the first postoperative week. This diagnosis was confirmed with the presence of a temporal scotoma revealed by the computerized visual field (first reported in this study) and also reducing the pupil area with miotic drops. The treatment of this complication was performed by using brimonidine tartrate and after 6 months this symptom completely disappeared as confirmed by the computerized visual field. The treatment should be based on reducing the pupil area with miotic drops and we also recommend to observe these cases until the 6th postoperative month before indicating an IOL exchange since the capsular edge that overlaps the IOL may opacify creating an optical barrier reducing or eliminating negative dysphotopsia.

[Unintentional staining of lens posterior capsule with trypan blue during extracapsular cataract extraction: case report]. / Impregnação inadvertida da cápsula posterior do cristalino com azul de tripano durante a facectomia extracapsular: relato de caso.

Report of a complication related to the use of 0.1% trypan blue during capsular staining of the anterior crystalline lens capsule in an extracapsular cataract extraction with intraocular lens implantation. The capsular dye was injected using an air-bubble technique, inadvertently, it was done using high pressure dispersing the dye through the zonules leading to a complete lost of red reflex, the following steps of the procedure becoming more difficult after the cataract extraction and causing a temporary disturbance of visual acuity in the postoperative period. In order to avoid this complication, the authors also describe the use of "Modified air-bubble technique" where dispersive viscoelastic is placed into the iridolenticular space 360 degrees to create a protection barrier.

Impregnacão inadvertida da cápsula posterior do cristalino com azul de tripano durante a facectomia extracapsular: relato de caso / Unintentional staining of lens posterior capsule with trypan blue during extracapsular cataract extraction: case report

Relato de complicacão relacionada ao uso do azul de tripano 0,1 por cento ocorrida ao corar a cápsula anterior do cristalino em facectomia extracapsular com implante de lente intra-ocular. O corante foi injetado sob alta pressão utilizando a técnica de bolha de ar ocasionando a migracão deste através da zônula e conseqüente perda do reflexo vermelho no peroperatório dificultando os passos subseqüentes à extracão da catarata e comprometendo temporariamente a acuidade visual no pós-operatório. Tendo como objetivo evitar esta complicacão, os autores descrevem ainda, o uso da "Técnica de bolha de ar modificada" no qual o viscoelástico dispersivo é injetado no espaco iridolenticular 360º para compor uma barreira de protecão.

Comparação dos custos da cirurgia de catarata em um hospital público utilizando duas incisões distintas (córneoescleral e túnel escleral) para a técnica de facectomia extra-capsular com implante de lente intra-ocular / Financial comparison of cataract surgery in a public hospital using two different incisions (corneoscleral and scleral tunnel) to the extracapsular extraction of a cataract wich an intraocular implant

Objetivo: Comparar o faturamento da cirurgia de catarata no Departamento de Oftalmologia da Faculdade de Medicina ABC (FMABC) utilizando duas incisões distintas (córneoescleral e túnel escleral) para a técnica de facectomia extra-capsular (FEC) com implante de lente intra-ocular tendo como base o astigmatismo induzido. Métodos: Foi realizado um estudo prospectivo randomizado utilizando 32 pacientes distribuídos em dois grupos. Estes foram submetidos à facectomia (FEC) com implante de lente intra-ocular (LIO) tendo como única variável o tipo de incisão, utilizando incisão córneoescleral no grupo A e túnel escleral no grupo B. A medida do astigmatismo induzido foi realizada na primeira semana, quarta semana, no terceiro mês e sexto mês utilizando videoceratoscopia. A necessidade de retirada de pontos na sétima semana e de retornar na nona semana foram comparadas entre os grupos. O valor de cada procedimento foi fornecido pelo Departamento financeiro da FMABC. Resultados: O astigmatismo induzido foi estatisticamente significante na primeira e quarta semanas no grupo A quando comparado ao grupo B (p<0.05). Porém, a partir do terceiro mês, não houve diferença estatística. Sete pacientes do grupo A (77,78%) e dois do grupo B (22,22%) necessitaram retornar na nona semana, portanto, o grupo A apresentou uma redução no faturamento de 55,4% maior do que no grupo B. Conclusão: A FEC com implante de LIO utilizando a incisão túnel escleral proporcionou um menor astigmatismo induzido, estabelecendo assim, uma menor redução do faturamento decorrente da diminuição do número de reavaliações quando comparada à técnica córneoescleral.
