Observational Study of 10 Cases of Lamellar Corneal Transplants Performed at a Tertiary Hospital - Abstract
Introduction: In recent decades, with the advancement of research, lamellar corneal transplants have gained an increasingly significant role in the treatment of corneal disorders. However, as this technique becomes more popular, also observe an increase in descriptions of associated complications Objectives: This study aims to analyze ten cases of lamellar transplants in Pontifical Catholic University Campinas Hospital. The study will report indications for lamellar corneal transplants, associated ocular pathologies, and prior surgeries. It includes an evaluation of pre and post-operative visual acuity describe complications, graft rejection and failure. As a secondary objective, the study aims to analyze and quantify patient data for potential future approaches and strategies in this specific service and context. Materials and methods: The study was conducted in a descriptive and retrospective manner, utilizing secondary data obtained from ophthalmological medical records of patients undergoing lamellar corneal transplants at PUC-Campinas Hospital. Patient details, including gender and age, eye laterality, preoperative diagnosis, type of lamellar transplant, and any previous ocular surgeries were analyzed. Visual acuity was assessed both pre and posttransplant, while intra and post-operative complications, the presence of rejection, and the progression to graft failure were monitored. Results: Ten lamellar corneal transplants performed in the department were analyzed. Gender: 60% male (M), 40% female (F); 30% left eyes (OS), 70% right eyes (OD); diagnosis: 70% preoperatively diagnosed with pseudophakic bullous keratopathy (PBK), 20% with Fuchs’ endothelial dystrophy, 10% with macular dystrophy; previous eye surgeries: 80% underwent phacoemulsification with intraocular lens implantation.Conclusion: Lamellar corneal transplant techniques have stood out due to their enhanced effectiveness and safety, providing a quicker and more efficient
visual rehabilitation, reducing induced astigmatism, and minimizing changes in the refractive power of the transplanted cornea. Additionally, they significantly reduce the risk of graft rejection and failure.
