ABSTRACT
PURPOSE: This study is to describe the clinical outcome of penetrating keratoplasty combined with implantation of a novel intraocular lens with an artificial iris, aided by continuous vitreous chamber infusion, in patients with severe aniridia and corneal alterations. METHODS: This was a prospective single-center case series study involving five patients with corneal alterations and aniridia. All subjects underwent simultaneous penetrating keratoplasty and implantation of a new intraocular lens with an artificial iris with the assistance of infusion into the vitreous chamber to regulate intraocular pressure during the surgical procedure. Visual acuity, corneal endothelial cell density, and intraocular pressure assessments were performed in the postoperative period. The final cosmetic outcome of the iris prosthesis placement was also evaluated. RESULTS: In all cases, increased visual acuity and a good aesthetic result were observed in all affected eyes except one in which, despite the excellent aesthetic outcome, the eye was very hypotonic as it had high myopia and had undergone several previous surgeries. CONCLUSION: The single surgical procedure combining implantation of an intraocular lens-iris prosthesis with penetrating keratoplasty is an effective technique for the simultaneous treatment of aphakia and aniridia. However, larger series with longer-term follow-up are needed to definitively establish the benefits of this technique.

PURPOSE: To report our first clinical and patient-reported outcomes in the early postoperative period with a new model of trifocal diffractive intraocular lens (IOL). METHODS: Pilot prospective analysis of the results of 26 eyes of 13 patients (age, 44-79 years) undergoing cataract surgery with implantation of the trifocal diffractive IOL Liberty 677MY (Medicontur Medical Engineering Ltd., Zsámbék, Hungary). The following clinical outcomes were evaluated during the first postoperative month: measurement of distance, intermediate and near visual acuity, binocular defocus curve, and level of spectacle independence, patient satisfaction, perception of photic phenomena, and difficulty in performing several vision-related daily tasks by means of a questionnaire. RESULTS: Mean binocular LogMAR uncorrected distance, intermediate and near visual acuities were -0.03 ± 0.13, 0.21 ± 0.16, and 0.16 ± 0.09, respectively. Furthermore, 100.0%, 84.6% and 92.3% of patients achieved a binocular corrected distance, distance-corrected intermediate and distance-corrected near visual acuity of 20/32 or better, respectively. In the defocus curve, visual acuities were better than 0.2 logMAR for defocus levels between +1.00 and -3.00 D. Spectacle independence was referred by all patients, with any of them reporting dissatisfaction with the outcome of the surgery. The postoperative vision did not lead to difficulties in the daily life in 92.3% of patients. Bothersome halos, glare or starbursts were only reported by only 7.7% of patients. CONCLUSIONS: The trifocal IOL evaluated provides a successful visual rehabilitation with minimal photic phenomena associated, leading to high levels of spectacle independence and patient satisfaction.

Las duplicaciones intestinales son anomalías infrecuentes; el sitio de presentación más común es el ileon terminal. Se presenta el caso de un niño con malformación doble de ileon terminal (triplicación) con porción tubular y quística simultánea a una duplicación esofágica. Esta anomalía probablemente no ha sido descrita; y debe ser excepcional. El cuadro se inició con dolor abdominal, sangrado del tubo digestivo y posteriormente abdomen agudo. El diagnóstico se estableció mediante gammagrafía con Tecnecio 99 en el caso de la lesión intestinal; con radiografía de tórax, esofagograma y tomografía axial por computadora de la lesión torácica. Se trataron quirúrgicamente ambas anomalías; la torácica por toracotomía derecha; las lesiones intestinales con laparotomía exploradora y resección del ileon terminal en las partes afectadas

Se presenta el caso de una paciente de tres días de nacida con diagnóstico de atresia de esófago y una fístula traqueoesofágica de segmentos sumamente separados. El abordaje quirúrgico consistió en: 1. Miotomóa es espiral (cuatro vueltas) para elongar el esófago proximal. 2. Anastomosis término-terminal de primera intención para la reconstrucción del esófago en periodo neonatal
