Resumen
Objective: To analyze, in a university hospital of reference, the rate of a new penetrating corneal transplantation in patients that had previously undergone a tectonic keratoplasty and analyze the results after one year of surgery. Methods: Retrospective review of patients undergoing penetrating corneal transplantation, from november of 2010 to november of 2014. Comparative analysis of best corrected visual acuity (BCVA), intraocular pressure and corneal transparency before surgery and after one year, in the group of patients in which it was performed a re-graft after a failed tectonic transplantation. Results: A total of 318 patients underwent penetrating corneal transplantation during the study period. Of the 199 patients who underwent tectonic transplantation, 36 were subjected to re-graft and re-grafts were performed more than once in 2 eyes, with total of 38 transplants (19,09%). The results showed improvement of BCVA in 20 (52.63%), worsening in 8 (21.05%) and unchanged in 10 (26.31%); improvement of intraocular pressure in 3 (7.89%), deterioration in 3 (7.89%) and unchanged in 32 (84.21%); improvement of corneal transparency 25 (65.78%), worsening 4 (10.52%) and 9 unchanged (23.68%) patients. Conclusion: This study demonstrated a considerable number of repeated penetrating keratoplasty in patients with a history of failed tectonic corneal transplantation. In spite of bad prognosis in cases where there is high-risk corneal recipients and history of a failed tectonic transplant, there was improvement of the corneal transparency and best corrected visual acuity even after a year of surgery. 74 6 355 357 Williams, K.A., Coster, D.J., The immunobiology of corneal transplantation (2007) Transplantation., 84 (7), pp. 806-813 Huang, T., Planck, S.R., Rosenbaum, J.T., Lee, E.J., Feasibility study of lamellar keratoplasty in a murine model (2009) Ocul Immunol Inflamm., 17 (4), pp. 257-264 Ehlers, N., Hjortdal, J., Nielsen, K., Corneal grafting and banking (2009) Dev Ophthalmol., 43 (1), pp. 1-14 Terry, M.A., Mark, A., The evolution of lamellar grafting techniques over twenty-five years (2000) Cornea., 19 (5), pp. 611-616 Qu, L.J., Xie, L.X., Changing indications for lamellar keratoplasty in Shandong, 1993-2008 (2010) Chin Med J (Engl), 123 (22), pp. 3268-3271 Patel, N.P., Kim, T., Rapuano, C.J., Cohen, E.J., Laibson, P.R., Indications for and outcomes of repeat penetrating keratoplasty, 1989-1995 (2000) Ophthalmology., 107 (4), pp. 719-724 Panda, A., Vanathi, M., Kumar, A., Dash, Y., Priya, S., Corneal graft rejection (2007) Surv Ophthalmol., 52 (4), pp. 375-396 Williams, K.A., Lowe, M., Bartlett, C., Kelly, T.L., Coster, D.J., Risk factors for human corneal graft failure within the Australian corneal graft registry (2008) Transplantation., 86 (12), pp. 1720-1724 Bachmann, B., Taylor, R.S., Cursiefen, C., Corneal neovascularization as a risk factor for graft failure and rejection after keratoplasty: an evidence-based meta-analysis (2010) Ophthalmology., 117 (7), pp. 1300-1305.e7 Ti, S.E., Scott, J.A., Janardhanan, P., Tan, D.T., Therapeutic keratoplasty for advanced suppurative keratitis (2007) Am J Ophthalmol., 143 (5), pp. 755-762.e2 Yokogawa, H., Kobayashi, A., Yamazaki, N., Masaki, T., Sugiyama, K., Surgical therapies for corneal perforations: 10 years of cases in a tertiary referral hospital (2014) Clin Ophthalmol, 8, pp. 2165-2170 Bersudsky, V., Blum-Hareuveni, T., Rehany, U., Rumelt, S., The profile of repeated corneal transplantation (2001) Ophthalmology., 108 (3), pp. 461-469 Weisbrod, D.J., Sit, M., Naor, J., Slomovic, A.R., Outcomes of repeat penetrating keratoplasty and risk factors for graft failure (2003) Cornea., 22 (5), pp. 429-434 Yildiz, E.H., Hoskins, E., Fram, N., Rapuano, C.J., Hammersmith, K.M., Laibson, P.R., Third or greater penetrating keratoplasties: indications, survival, and visual outcomes (2010) Cornea., 29 (3), pp. 254-259
