ABSTRACT

El buen desempeño de los LIOs (Lentes Intraoculares) tipo tóricos, se basa en que la rotación del implante sea mínima y en la adecuada selección preoperatoria de los pacientes. En este estudio, se describió el comportamientos de estos LIOs en nuestra población, por medio de la medición de diferentes parámetros de calidad visual aportados por el OPD Scan III, teniendo en cuenta la técnica quirúrgica y demarcación de un solo cirujano. Aunque la muestra no fue lo suficientemente grande para permitir resultados estadísticamente significativos, estos demuestran una relación directamente proporcional de la rotación con las aberrometrías de alto orden e inversamente proporcional con las agudezas visuales, a pesar de que la rotación máxima fue sólo de 15 grados. Se sugiere continuar este estudio con otro de tipo analítico e incluyendo LIO multifocales para la medición de descentramiento y su repercusión sobre parámetros de calidad visual medidos con el OPD Scan III.


The good performance of toric intraocular lens is based on implant minimal rotation and appropriate preoperative patient selection. In this study, we described the results of these IOLs in our population, by measuring different visual quality parameters provided by the OPD Scan III, considering the surgical technique and demarcation of a single surgeon. Although the sample was not large enough to allow statistically signifi cant results, these show a directly proportional relationship of the rotation with high order aberrations and inversely proportional to visual acuity, even though the maximum rotation was only 15 degrees. This study should continue with analytical studies including multifocal IOLs to describe descentration and its impact on visual quality parameters measured with the OPD Scan III.

ABSTRACT

Objetivo: evaluar los resultados visuales después de cirugía de catarata con implante de lente multifocal tórico. Materiales y Métodos: se realizó un estudio observacional descriptivo tipo serie de casos, de pacientes que se operaron de catarata con implante de lente multifocal tórico Acrysoft IQ Restor (Alcon Labs, Inc, Fort Worth Texas) desde Abril del 2011 hasta Abril de 2013 en la Fundación Oftalmológica de Santander (FOSCAL). Se evaluaron la agudeza visual sin corrección en visión lejana (AVSCVL, a 6 m) y cercana (AVSCVC a 40cm), el equivalente esférico postoperatorio (EEPOP), el astigmatismo refractivo residual, el astigmatismo inducido por el cirujano (AIC) y el uso de gafas a los 3 meses del post-operatorio. Resultados: el estudio incluyó 36 ojos (23 pacientes) con catarata y astigmatismo corneal. La AVSCVL promedio post-operatoria fue 0.21 logMAR, la AVSCVC promedio post-operatoria fue 0.22 logMAR. El EEPOP fué 0.1 D. El astigmatismo refractivo residual promedio fue -0.34 D. El astigmatismo inducido por el cirujano fue de 0.36 D. El uso de gafas para la visión lejana, próxima y en ambas distancias fue de 0%, 13% y 17% respectivamente. El 65% del total de los pacientes no usa gafas. Conclusión: el implante de lente multifocal tórico en pacientes con catarata y astigmatismo corneal regular muestra muy buenos resultados en la agudeza visual lejana y cercana, permitiendo a los pacientes gozar de independencia de gafas.


Objective: to evaluate visual outcomes after cataract surgery with toric multifocal intraocular lens (IOL). Materials and Methods: this is a case series study which included patients who had cataract surgery with implantation of an Acrysof IQ Restor toric IOL from April 2011 until April 2013 at Fundación Oftalmológica de Santander (FOSCAL). We evaluated uncorrected distance visual acuity, uncorrected near visual acuity, spherical equivalent refraction, residual astigmatism, surgeon induced astigmatism and spectacles use at 3 months post-operatively. Results: the study included 36 eyes (23 patients) with cataract and corneal astigmatism. The mean UCDVA was 0.21 logMAR, mean UCNVA was 0.22 logMAR. The spherical equivalent was 0.1 D. The residual refractive astigmatism was -0.34 D. Surgeon-induced astigmatism was 0.36 D. The use of glasses for distance vision, near vision and both was 0 %, 13 % and 17 %, respectively. 65% of the patients don't wear glasses. Conclusion: implantation of toric multifocal IOL in patients with cataract and regular corneal astigmatism showed good outcomes in distance and near vision, allowing patients get independence from spectacle wear.

ABSTRACT

Objetivo: describir una nueva técnica quirúrgica para realizar queratoplastia lamelar profunda que facilita la disección de planos corneales a un espesor predeterminado, utilizando instrumental con el cual el cirujano de córnea está familiarizado. Métodos: se describe el caso de una paciente de 32 años con queratocono avanzado sin antecedente de hidrops, cicatrices estromales de la córnea o cirugía previa. Se realizó queratoplastia lamelar profunda en el ojo izquierdo inicialmente y tres meses después en el ojo derecho efectuando el procedimiento a profundidad conocida utilizando instrumental para implante de segmentos intraestromales Intacs® (Addition Technology, Inc., Fremont, CA). Se determinó un plano corneal con el disector de Melles (DORC®, Spijkenisse, Países Bajos) con posterior inyección de viscoelástico para su separación y realización del corte con trépanos de Barron (Katena products, inc. Denville, USA) para donante y receptor de un mismo diámetro (8mm) con sutura combinada con nylon 10-0 (Ethicon, Inc, San Angelo, USA). Resultados: se realizó seguimiento a 4 años con una AVSC de 20/150+1 OD y 20/80-1 OI. La mejor visión corregida lejana fué de 20/25 en OD y 20/20- en el OI. Conclusiones: la queratoplastia lamelar profunda asistida por tunelizador corneal promete ser una técnica segura que permite efectuar la disección a una profundidad planeada sin penetrar a cámara anterior. Se observaron excelentes resultados con una técnica amigable para el cirujano de córnea sin incrementar significativamente el tiempo quirúrgico y además, permitiendo obtener las ventajas al preservar el endotelio corneal con una técnica con cámara cerrada.


Purpose: to describe a new surgical technique for deep lamellar keratoplasty which facilitates corneal lamellar dissection to a predetermined thickness using instruments known by a corneal surgeon to implant Intacs intrastromal ring segments. Methods: We described a case of a 32 year old patient without history of hydrops, corneal stromal scars or previous corneal surgery. Deep lamellar keratoplasty was performed initially in the left eye and three months later in the right eye performing procedure in a known depth using Intacs® Prolate System (Addition Technology, Inc. Fremont, CA). Lamellar corneal dissection was performed with Melles dissector (DORC®, Spijkenisse Netherlands) and viscoelastic substance was injected to dissect planes. Trephination was performed with Barron-Hessburg corneal system (Katena products, inc. Denville, USA) with same size for donor and recipient (8mm) and sutured with a combined 10-0 Nylon suture technique (Ethicon, Inc, San Angelo, USA). Outcome: 4-years follow-up has show an UCVA of 20/150(+1) OD and 20/80(-1) OS. Best corrected distance vision of 20/25 OD and 20/208(-1) in OS were achieved. Conclusions: prolate system corneal assisted deep anterior lamellar keratoplasty promises to be a safe and novel technique allowing corneal dissection to a planned depth without anterior chamber penetration. Excellent results in a friendly technique to any corneal surgeon offers standard surgical time and the advantage to preserve recipient endothelium layer in a closed anterior chamber surgical technique.

ABSTRACT

Objetivo: examinar resultados anatómicos y visuales de los pacientes con membranas epirretinianas idiopáticas (MER) tratados mediante pelaje de membranas y su correlación funcional post-operatoria. Métodos: Estudio de serie de casos donde se revisaron las historias clínicas de 27 pacientes elegidos de manera aleatoria y a quienes se realizó pelaje de membranas epirretinianas idiopáticas con seguimiento clínico por 6 meses del post-operatorio. Al 90% (n=24) de los pacientes se les realizó cirugía combinada de facovitrectomía. Se tomaron como variables a analizar la agudeza visual pre y post-operatoria a la semana, al mes y a los 6 meses, tomografía de coherencia óptica pre y post-operatoria al mes y a los 6 meses de la cirugía. Se comparó la agudeza visual y el grosor retiniano en el milímetro central entre la medida pre y postoperatoria utilizando la prueba de t de student. Resultados: la media de agudeza visual pre-operatoria fué de 20/60 y post-operatoria (6 meses) de 20/30. La media del grosor retiniano en el milímetro central pre-operatoria resultó 409.7 micras con un valor post-operatoria (6 meses) de 341 micras. En el 82% de los pacientes se observó una mejoría en la agudeza visual post-operatoria a los 6 meses. Los pacientes con mejores agudezas visuales fueron aquellos cuya agudeza visual pre-operatoria estuvo alrededor del 20/50. Conclusiones: la agudeza visual y el grosor retiniano pre-operatorio son los mejores factores pronósticos para estimar la agudeza visual post-operatoria en pacientes operados con diagnóstico de MER. La agudeza visual post-operatoria definitiva se alcanza posterior a los 6 meses de la cirugía. Se recomienda establecer como punto de corte para la decisión quirúrgica aquellos pacientes con agudezas visuales de 20/50 o peor.


Objective: to examine anatomic and visual outcomes in patients undergoing epiretinal membrane surgery. Methods: a case series study. Twentyseven eyes from 27 patients who underwent epiretinal membrane surgery were reviewed. Correlations between preoperative and first week, one and six months post-operative bestcorrected visual acuity and Optical Coherence Tomography (OCT) findings were obtained and analyzed using t student test. Results: mean pre-operative best corrected visual acuity (BCVA) was 20/60 and six months post-op was 20/30. Mean pre-op retinal central thickness was 409.7 microns and six months post-op was 341 microns. BCVA significantly improved in 82% of the patients after six months of surgery. Patients whom achieved higher BCVA levels post-op were those with pre-op BCVA around 20/50. Conclusions: pre-operative BCVA and central retinal thickness are the most importante factors to estimate post-operative BCVA. Highest BCVA levels were achieved after six months of surgery. It is recommended to use pre-op BCVA of 20/50 as cut-off level to consider surgical treatment.

ABSTRACT

PURPOSE: To analyze trends in rhegmatogenous retinal detachment (RRD) surgery among the members of the Korean Retina Society from 2001 to 2013. METHODS: In 2013, surveys were conducted by email and post to investigate the current practice patterns regarding RRD treatment. Questions included how surgeons would manage six cases of hypothetical RRD. Results were compared to those reported in 2001. RESULTS: A total of 133 members (60.7%) in 2013 and 46 members(79.3%) in 2001 responded to the survey. Preference for pneumatic retinopexy has decreased in uncomplicated primary RRD (p = 0.004). More respondents in 2013 selected vitrectomy as the primary procedure when mild vitreous hemorrhage (p = 0.001), myopia (p = 0.044) and history of successful scleral buckling on the fellow eye (p = 0.044) were added to the primary scenario. Vitrectomy was over twice as popular in cases of pseudophakic, macula-off RRD with posterior capsular opacity (p = 0.001). CONCLUSIONS: For RRD with myopia, pseudophakia and media opacity, surgical interventions over the last decade have drastically shifted from scleral buckling and pneumatic retinopexy to vitrectomy.

ABSTRACT

Glaucoma is a serious sight-threatening disorder aptly named the Silent thief of sight. India, being the second most populous country in the world, has about 20% of the world glaucoma population. The complex geographical and socioeconomic architecture and the economic extremes have a profound effect on its health system. The present times are abundant with fresh developments in the field of glaucoma. Though newer modalities are present in India, they are not ample and are unequally distributed. Adherence and persistence with medical therapy is an issue owing to a multitude of factors. In such a setting, most of the ophthalmologists find themselves performing glaucoma surgeries quite often. In the present era, there are a number of new surgeries to choose from, especially procedures which are nonpenetrating and blebless. Faced with a spectrum of surgeries from shunts to canal surgeries and trabecular bypass devices, the surgeon is often in a dilemma. Still, trabeculectomy remains the gold standard with an increasing trend toward glaucoma drainage devices. The new procedures and devices are worth exploring but await long-term results, good training of surgeons and cost effectiveness.

ABSTRACT

Foram estudados 96 olhos com comprimento axial menor que 22.0 mm, submetidos a facectomia extracapsular com implante de lente intraocular de câmara posterior. O "folow-up" mínimo foi de 3 meses e o máximo de 84, com média de 24 meses, o poder dióptrico das lentes variou de 20.0 a 28.0, com média de 23.5. Näo foram observadas complicaçöes intra e pós-operatórias que comprometessem a acuidade visual final, com 89.6% dos casos alcançando 20/40 ou melhor. Do ponto de vista refracional, obtivemos com a fórmula SRKII um erro menor que 0.50, 1.25 e 2.00 dioptrias em 23.9%,61.4% e 87.5% dos casos, respectivamente. Com a fórmula SRK, observamos percentuais similares (28.1%, 66.7% e 83.3%). Porém, foi observada a tendência de se manter o olho pseudofácico hipermétrope em 66.7% dos casos, com a SRK e míope em igual percentual com a SRKII

ABSTRACT

Entre 100 pacientes com diagnóstico angiográfico de degeneraçäo macular relacionada a idade 23 exibiram sinais hipofluorescentes sugestivos e indiretos de eventual espessamento a nível do epitélio pigmentar e ou estruturas contíguas. Embora näo haja confirmaçäo histo-patológica, estes aspectos podem fazer parte dos fatores envolvidos na gênese deste quadro. A hipofluorescência definida a partir do tempo de trânsito do corante pode vir ou de um déficit perfusional na coriocapilar ou de um bloqueio mecânico ou difusional do corante
