    OBJETIVOS: Relatar os resultados de vitrectomia via pars plana com utilização de perfluocarbono líquido (Perfluoroctano-Ophtalmos®), como tamponante vítreo-retiniano de curta duração, no pós-operatório de portadores de descolamento de retina, por ruptura gigante. MÉTODOS: Estudaram-se dez desses pacientes. Todos os casos eram complicados por vitreorretinopatia proliferativa grau B ou pior com rupturas que variavam em extensão de 90º a 210º. O perfluorocarbono líquido foi introduzido, por via pars plana, com o volume necessário para ultrapassar o limite posterior da ruptura, permanecendo no pós-operatório por cinco dias, estando os pacientes em decúbito dorsal. Após esse período submetiam-se a segunda intervenção para troca do perfluorocarbono líquido para gás ou óleo de silicone. RESULTADOS: Após período de acompanhamento médio de 16,2 ± 12,4 meses (2 a 43 meses), 80% das retinas estavam aplicadas, sendo necessária a repetição desta técnica em 1 caso (10%) caso e em 2 casos (20%) não houve reaplicação da retina por vitreorretinopatia avançada. Houve melhora da acuidade visual em 5 casos (50%). CONCLUSÃO: Observaram-se bons resultados quanto à aplicação da retina (80%) e melhora da acuidade visual (50%) quando do uso do perfluorocarbono líquido como tamponante vitreorretiniano de curta duração no pós-operatório de cirurgias de descolamento de retina por rupturas gigantes.

    PURPOSE: To report the visual outcomes and complications of congenital cataract surgery with primary intraocular lens implantation in microphthalmic eyes of children younger than 4 years of age. METHODS:This retrospective interventional case series included 14 microphthalmic eyes from 10 children who underwent congenital cataract surgery with primary intraocular lens implantation younger than 4 years of age. Seven patients had bilateral cataracts (11 eyes met the study's inclusion criteria) and 3 patients had unilateral cataract. Patients' medical charts were reviewed to obtain information regarding the preoperative and postoperative ophthalmological examination. Main outcome measures were intraocular pressure (IOP), best-corrected visual acuity, and intraoperative and postoperative complications. RESULTS: Mean age at the time of surgery was 21.7 ± 2.9 months. Mean ocular axial length was 19.2 ± 0.9 mm. Mean preoperative IOP was 9.7 ± 1.7 mmHg and 10.3 ± 3.1 mmHg on final follow-up (P=0.18). There were no intraoperative complications. Two (15.4%) eyes developed secondary visual axis opacification, of which only one needed to be reoperated due to significantly decreased vision (0.5 logMAR). Preoperative and postoperative best-corrected visual acuity was 2.09 ± 0.97 logMAR and 0.38 ± 0.08 logMAR in bilateral cases and 1.83 ± 1.04 logMAR and 0.42 ± 0.13 logMAR in unilateral cases, respectively. CONCLUSION: Primary intraocular lens implantation in congenital cataract surgery in microphthalmic eyes resulted in a significant best-corrected visual acuity improvement with no intraoperative complications and minimal postoperative complications.

    ABSTRACT Purpose: To assess the efficacy of using a nonste­roidal anti-inflammatory drug preoperatively and of applying the re-dilation technique when necessary to minimize pupil size variation when comparing the degree of mydriasis before femtosecond laser pretreatment with that at the beginning of phacoemulsification. Methods: This retrospective study included patients who underwent cataract surgery using the LenSx (Alcon Laboratories, Inc., Fort Worth, TX). Our routine dilating regimen with flurbiprofen, tropicamide, and phenylephrine was used. The re-dilation technique was applied on eyes that manifested with a pupillary diameter that was smaller than the programmed capsulotomy diameter after laser pretreatment. The technique consists of overcoming pupillary contraction by instilling tropicamide and phenylephrine before phacoemulsification. Pupil size was assessed before femtosecond laser application and at the beginning of phacoemulsification. Results: Seventy-five eyes (70 patients) were included. Nine (12%) eyes underwent the re-dilation technique. There was no significant difference in mean pupillary diameter and mean pupillary area between the two studied surgical time points (p=0.412 and 0.437, respectively). The overall pupillary area constriction was 2.4 mm2. Immediately before opening the wounds for phacoemulsification, none of the eyes presented with a pupillary diameter <5 mm, and 61 (85.3%) eyes had a pupillary diameter >6 mm. Conclusion: Preoperative administration of nonsteroidal anti-inflammatory drug and the re-dilation technique resulted in no significant pupil size variation in eyes that were pretreated with the femtosecond laser, when comparing the measurements made before the laser application and at the beginning of phacoemulsification. This approach can avoid the need to proceed with cataract extraction with a constricted pupil.

    OBJETIVO: Avaliar o impacto das doenças oculares sobre a qualidade de vida de uma população idosa do sertão de Pernambuco, localizado na região nordeste do Brasil. MÉTODOS: Foram entrevistados 580 indivíduos acima de 59 anos, por meio do questionário de avaliação de qualidade de vida "Visual Functioning Questionnaire" (VFQ). Todos os indivíduos foram submetidos a exame oftalmológico completo. Os resultados das variáveis quantitativas foram expressos por suas médias e desvios- padrão. Os resultados das variáveis qualitativas foram expressos por suas frequências absolutas e relativas. RESULTADOS: A média de idade foi de 70 ± 8,1 anos. Cerca de 86,0% dos entrevistados declararam ser analfabetos ou ter o ensino fundamental incompleto. As principais queixas foram: baixa visual (71,1%) e ardor/prurido (69,0%). A acuidade visual não era normal em 37,4% dos idosos. Por volta de 75,0% dos entrevistados relataram ter saúde regular ou ruim, e 77,0% diziam ter uma visão regular ou ruim. A qualidade de vida foi considerada pior conforme a piora da condição visual do idoso. CONCLUSÃO: O déficit visual representou um impacto negativo sobre a qualidade de vida dos idosos do sertão Pernambucano.

    Abstract We report an unusual case of a 65-year old patient that developed localized bilateral Descemet membrane detachment during non-simultaneous femtosecond laser-assisted cataract surgery (FLACS). The detachment occurred when the laser was performing the secondary incision. In the operating room, the isolate-and-release technique was used to effectively manage this complication. To the best of our knowledge, this is the first reported case of bilateral Descemet membrane detachment during FLACS.

    OBJECTIVE: To evaluate clinical features of patients related to opacification of hydrophilic acrylic intraocular lenses, four years after surgery. METHODS: We evaluated six cases of late opacification of Ioflex intraocular lenses (case group) compared to 24 patients (control group) with no opacification. Both groups underwent phacoemulsification as a result of a community campaign for underprivileged people. Patients who underwent bilateral cataract surgery had only the right eye included on the study. The patients were submitted to ophthalmic examination, including measurements of corrected distance visual acuity and biomicroscopy slitlamp evaluation. Detailed medical histories were obtained. Surgical details were retrieved. RESULTS: Systemic arterial hypertension was recorded in 4 patients from the case group and 11 in the control group, with no statistically significant difference between groups. A single patient in the control group had diabetes mellitus, and so was not considered for statistical analysis. No environmental factor could be related. There were no statistically significant differences for mean visual acuity between the groups of patients regarding the evaluation periods. One eye in the control group received an Ioflex intraocular lens with the same lot number as one of the opacified lenses. CONCLUSION: No clear patient factor could be related to late Ioflex lens opacification.

    Purpose: To evaluate the incidence of posterior capsule opacification (PCO) four years after the implantation of a hydrophilic acrylic intraocular lens (IOL). Methods: Fifty-eight randomly selected eyes from 58 patients were analyzed four years after phacoemulsification and Ioflex IOL implantation. The patients underwent an ophthalmic examination to detect PCO and a detailed medical history was obtained. The patients' charts were reviewed for their corrected distance visual acuity prior to the IOL implantation, as well as for one month postoperatively. The Student's t-test was used for statistical analysis. Results: The mean age of patients without PCO was 74.6 ± 9.5 years, compared to 70.3 ± 15 years in patients with PCO. Four years after surgery, 39 of the 58 eyes (67%) had detectable PCO and 24 eyes (41.3%) had decreased visual acuity (VA) due to PCO. These patients were referred for Nd:YAG laser capsulotomy. Three patients (5.1%) had decreased VA due to glaucoma, IOL opacification, or age-related macular degeneration. Twelve eyes (20.7%) presented mild PCO with unchanged VA. Systemic arterial hypertension was reported by 45% of the patients, and in 3.5% of these cases this was associated with diabetes mellitus. Conclusion: This study found the incidence of PCO to be 67% four years after phacoemulsification and Ioflex IOL implantation.
