Abstract

Indonesia merupakan negara yang terbentuk akibat tumbukan dari tiga lempeng tektonik, hal ini menyebabkan terbentuknya gunungapi, sehingga proses mineralisasi akibat altrasi hidrotermal berkembang dibeberapa tempat. Tujuan dari penelitian ini yaitu untuk mengetahui komposisi mineral serta perkembangan mineral alterasi dan petrogenesis berdasarkan sampel Bor lapangan “X” berdasarkan analisis data XRD dan data Bor. Hasil penelitian ditemui tiga intrusi yaitu, tonalit pada zona innerprophylitic-pottasic ditunjukan adanya mineral feldspar-Epidoteactinolit-biotit-Magnetit 78.3% , mikrodiorit berkembang pada zona innerprophylitic dengan kandungan chlorit-Zeolit-albitbiotit-magnetit 40.6% dan zona argillic illite-kaoline sebanyak 31.9%, dan diorite berkembang pada zona innerprophylitic-outherprophylitic dengan komposisi Chlorit-zeoliteepidote-biotitmagnetit 72.3%.

Abstract

Introduction & Objectives : Myopia is a major healthcare burden worldwide. Refractive surgery is used to correct refractive error for patients who wanted less reliance on glasses and contact lenses. LASIK is one of the most commonly used procedures for correction of myopia. This study aims to evaluate the long-term outcomes of LASIK procedure for myopia. Methods : A literature search was conducted for the years of 2017 to 2013 from PubMed with the search term "LASIK" AND "myopia" AND ("efficacy" OR "long-term outcomes"). All abstracts were reviewed and evaluated, and articles relevant to the topic was reviewed for this study. Results : Out of 71 articles from search results, 7 articles were selected for review. At the last follow up from 3-12 years, uncorrected distance visual acuity (UDVA) of -0.03 – 0.39 logMAR was achieved. Around 64% - 90% patients achieved UDVA of 20/20 or better. Myopic progression was found with the mean of 0.63 – 0.97 D. The efficacy index and safety index was at 0.67 - 1.01 MR and 1.02 - 1.09 respectively at the end of follow up. Conclusion : The data showed that LASIK had an excellent long-term safety and efficacy for treatment of myopia, although small percentage of patients experienced mild myopic progression.

Abstract

Introduction & Objectives : Infectious keratitis and endophthalmitis are rare yet devastating complications of corneal transplantation. Some studies have demonstrated increased incidence of infectious post-keratoplasty complications are related to contaminated corneal donor, although its risk factors remain controversial. This study provides concise review on possible risk factors of corneal donor contamination which related to post-keratoplasty infectious complications. Methods : This literature review was conducted by searching PubMed and Proquest for “corneal donor contamination” AND (“infectious complication” OR infection OR endophthalmitis) from the period of 2018-2023. Relevant articles were reviewed and selected for further understanding regarding various risk factors of corneal donor contamination leading to post-keratoplasty infectious complications and its preventive strategies. Results : The rate of corneal contamination varied between studies, ranging from 1,3 to 7,8%. The most common risks of contamination are donor’s diseases (e.g. cardiovascular, cerebrovascular accident) and prolonged time between death and donor retrieval. Longer preservation time (>5 days), environmental situation (temperature and humidity), and prolonged treatment duration on intensive care unit (>4 days) are also considered as its risk factors. Corneoscleral rim culture, addition of antifungal and antibacterial to corneal storage medium, and shortening of corneal processing time should be considered as probable preventive strategies. Conclusion : Donor diseases, prolonged donor retrieval time from death, and longer donor preservation and hospitalization duration, are associated with higher rates of corneal donor contamination. Rapid retrieval and donor handling time, together with corneoscleral rims culture, at least for fungus regarding its better predictive values, should be taken into consideration by corneal donors providing eye banks.
