24 Month Outcome of Gonioscopy Assisted Transluminal Trabeculotomy (GATT) in Eyes with Prior Corneal Transplant Surgery

INTRODUCTION: To compare the surgical outcomes of anterior chamber (AC) and posterior chamber (PC) implantation of iris claw lens (ICL) combined with penetrating corneal transplantation (P-CT), in eyes with no capsular support. METHODS: The records of 20 P-CT cases who underwent ICL implantation were retrospectively evaluated. The eyes were grouped according to the location of implantation; AC ICL and PC ICL. Pre- and post-surgical best-corrected visual acuity (BCVA), post-operative complications and graft rejection rates were compared between the two groups. Mean follow-up time was 28 (range, 12 and 76) months. RESULTS: ICLs were implanted during P-CT surgery in 14 (70%) eyes, and as a secondary procedure after P-CT in 6 (30%) eyes. ICLs were implanted in PC in 12 (60%) and in AC in 8 (40%) eyes. Mean preoperative BCVA was 0.064 (range, 0.001-0.02) in PC group and 0.02 (range, 0.001-0.1) in AC group (p=0.86). Mean postoperative BCVA was 0.17 (range, 0.0001-1.0) in PC group and 0.14 (range, 0.0001-0.4) in AC group (p=0.81). Glaucoma developed in 5 (41.6%) eyes with PC ICL. No eye with AC ICL developed glaucoma over time. DISCUSSION AND CONCLUSION: Both AC and PC ICL implantation provide favorable visual outcomes and complication rates in CT patients. However, PC implantation of ICL seems to increase glaucoma incidence.

First Time

We describe a case with complex Descemet membrane detachment (DMD) which persisted despite initial two failed surgical attempts to appose the ocular tissues. However, over time, tissue alignment was obtained spontaneously. A 60-year-old woman, operated trabeculectomy, had a total DMD intraoperatively during a complicated cataract surgery. Initial attempt to DM repositioning with intracameral air injection failed. Anterior Segment Optical Coherence Tomography (ASOCT) showed detachment of both DM and pre-Descemet’s layer (PDL). After consultation with a corneal surgeon, patient was again attempted for Intra-operative Optical Coherence Tomography (iOCT)-guided settlement of DMD with intracameral air which again failed. So, the patient was registered for lamellar corneal transplant, but at 3 months follow-up, DM had spontaneously attached, confirmed on ASOCT. This case shows for the first time that even complex DMDs involving PDL, can spontaneously appose despite failed surgical interventions.

Work Up

BackgroundThis study examined whether corneas from bacteremic donors could be used for corneal transplant.MethodsCorneas donated to the National Eye Bank of Taiwan between 1 January 2014 and 30 June 2017 were included in this study. All the corneas had corneoscleral rim cultures during the retrieval process and were hypothermic preserved in the Optisol-GS storage medium. A microbial work-up flow chart was used for the sterility check of all grafts. Bacteremic donors were defined as those whose last blood culture before corneal donation was positive. The microbial contamination rates, the endothelial cell densities, the tissue utility rates and early complications after transplants were compared between the corneas from bacteremic versus non-bacteremic donors.Results697 corneas from 356 donors were analysed, 70 of which were from bacteremic donors. The microbial contamination rates of the corneas from bacteremic and non-bacteremic donors (7.1% vs 9.1%)(p=0.30) were close. None of the contaminated corneas grew the same bacterial strains as those from their blood cultures. The corneas from bacteremic donors and non-bacteremic donors have similar endothelial cell densities (2931±297 cells/mm2 vs 2903 ± 470 cells/mm2) (p=0.63). Corneas from bacteremic and non-bacteremic donors shared a similar utility rate (98.6% vs 99.4%)(p=0.41). None of the corneas caused infectious complications after transplants.ConclusionOur study showed that corneas from bacteremic and non-bacteremic donors have equally low contamination rates and are of the same quality in terms of endothelial cell density and safety.

Abstract Background: Corneal transplantations are surgeries performed for irreparable corneal diseases and damage. However, there is a gap between the number of potential recipients and the number of donor corneas available. The main aim of the study was to determine the awareness and attitudes toward corneal donation among applicants and staff of DVLA, Kumasi-Ghana. Methods: A descriptive cross-sectional study was conducted. 100 participants were selected using convenient sampling method. A structured questionnaire was used to elicit responses from participants concerning awareness and attitudes toward corneal transplant. Results: The mean ± SD age of the participants was 32.05 ± 11.48years and age range, 18-67years. Males were 66% whilst females constituted 34%. 32.7% of the participants were aware of corneal donation. Majority of the participants were Christians (83.1%) and Singles (63%). Television was the source of information with the highest preponderance (49.4%). 67.3% were willing to donate their corneas after death. 63.9% were willing to indicate their donor statuses on drivers’ license form which had a significant association with willingness to donate cornea after death (p<0.05, ᵪ 2 = 12.187). Conclusion: There is a poor level of awareness (32.7%) of transplant and donation amongst the study population but a good level of willingness to donate organs (67%). Consent via driving license would seem to be a good potential mode of obtaining consent to supplement the harvesting of adequate tissues for transplant if adequate awareness is created.

Objetivou-se identificar o significado dos olhos nas representações sociais de clientes transplantados de córnea e suas implicações para o cuidado de si. Tratase de uma pesquisa descritiva qualitativa, adotando a Teoria das Representações Sociais na perspectiva de Moscovici. Fizeram parte deste estudo, 15 clientes submetidos a transplantes de córnea e que se encontravam em acompanhamento no Consultório de Oftalmologia do Ambulatório do Hospital Ophir Loyola, em Belém, PA. Os depoentes atribuíram significados diversos aos seus olhos, substanciados por sentimentos de tristeza e insatisfação, que contribuíram para mudanças significativas no cuidado de si. Há necessidade de se cogitar sobre o compromisso do enfermeiro com o cliente transplantado de córnea que, muitas vezes, encontra-se fragilizado, necessitando de um olhar mais atento.Descritores: Enfermagem, Transplante de Córnea, Cuidado de Si.Eye on the meaning of social representations corneal transplantation customers and it’s implications for the care of youThe aim of this study was to identify the meaning of the eyes of customers in the social representations of corneal transplant and its implications for self-care. It is a descriptive and qualitative study, adopting the Social Representation Theory in the context of Moscovici. The sample comprised 15 clients who underwent corneal transplantation and were followed up in the office of the Ophthalmology Clinic of the Ophir Loyola Hospital, in Belem, Pará. The respondents attributed different meanings to their eyes; substantiated by feelings of sadness and dissatisfaction, that contributed to significant changes in self-care. There is need to think about the commitment of the nurse with the client cornea transplant, which often is fragile, requiring a closer look.Descriptors: Nursing, Corneal Transplantation, Self-care.Los ojos sobre el significado de los clientes representataciones sociales transplante de córnea y sus conscuencias para el cuidad de ustedEl objetivo fue identificar el significado de los ojos de los clientes en las representaciones sociales de trasplante de córnea y sus implicaciones para el autocuidado.
