“…The proposed advantages of FLAK over traditional PK include faster postoperative healing and stitch removal, less postoperative refractive error, and decreased likelihood of wound dehiscence because of the increased contact surface area between the graft and the host. [139][140][141] Similar results were reported by Busin with manual dissection of a top hat configuration. 142 Rush et al reviewed their 18-month postoperative results for FLAK with 8.5/8.6-mm diameter zigzag trephinations in 12 patients with a history of either globe trauma with cornea scarring or failed penetrating keratoplasty.…”

Glaucoma is the leading cause of irreversible vision loss post-keratoplasty and an important cause of graft failure. With newer techniques, such as lamellar, endothelial, and laser-assisted keratoplasty as well as keratoprosthesis gaining popularity, clinicians will need to consider the incidence, risks, evaluation, and management of glaucoma for each type of keratoplasty when determining which type of transplant may be most appropriate. A comprehensive literature search of glaucoma in the setting of corneal transplantation was performed and serves as the basis for this review. Preexisting glaucoma and aphakia are notable risk factors. Patients that are candidates for deep anterior lamellar keratoplasty may benefit from reduced rates of post-keratoplasty glaucoma. Although glaucoma also complicates eyes with Descemet stripping endothelial keratoplasty, the severity is less and the intraocular pressure is more easily controlled when compared to penetrating keratoplasty. Endothelial keratoplasty creates unique perioperative issues mostly related to management of anterior chamber air bubbles.

“…3 In addition, this approach enables early suture removal. 4,5 Furthermore, this approach allows for either the endothelial or epithelial surface of the cornea to be transplanted widely as needed depending on the underlying disease. Finally, FLAK has demonstrated less endothelial cell damage and superior wound healing results compared with that which occurs after manual trephination.…”

“…Chamberlain et al studied postoperative astigmatism in a series of patients submitted to PK, comparing the manual technique with the FS laser-assisted procedure. (11) The latter provided better control of astigmatism in the early postoperative period. However, after 6 months of follow-up there was no significant difference in postoperative astigmatism between the two groups.…”

RESUMOApresentamos um relato de astigmatismo tardio progressivo pós-transplante de córnea para ceratocone, associado à afinamento periférico na junção doador-receptor, o que presumidamente pode ser considerado como recorrência da ectasia. O caso foi tratado por meio de Topoplastia de Cvintal assistida por laser de femtossegundo para a confecção da incisão com geometria "top hat", seguido de sutura com ajuste per-operatório guiado por ceratoscopia.Descritores: Astigmatismo/etiologia; Córnea/patologia; Ceratoplastia penetrante/efeitos adversos; Ceratocone/cirurgia; Terapia a laser/métodos; Complicações pós-operatórias; Relatos de casos ABSTRACTWe present a case of late high progressive astigmatism following penetrating keratoplasty for keratoconus, which was associated with peripheral thinning in the donor-receptor area, which may be recognized as recurrence of ectasia. Treatment was accomplished with Cvintal's Topoplasty assisted by femtosecond laser for a "top hat", followed by resuture with peroperative adjustment guided by ceratoscopy.
