Femtosecond laser-assisted deep anterior lamellar keratoplasty for keratoconus and keratectasia

摘要: Aim To describe the initial outcomes and safety of femtosecond laser-assisted deep anterior lamellar keratoplasty (DALK) for keratoconus post-LASIK keratectasia. Methods In this non-comparative case series, 10 eyes 9 patients underwent DALK procedures with a laser (Carl Zeiss Meditec AG, Jena, Germany). Of patients, 7 had 2 A 500 kHz VisuMax was used to perform corneal cuts on both donor recipient corneas. The outcome measures were uncorrected visual acuity (UCVA), best-corrected (BCVA), thickness, astigmatism, endothelial density count (EDC), power. Results All successfully treated. Early postoperative evaluation showed clear graft in all cases. Intraoperative complications included one small Descemet's membrane perforation. Postoperatively, there stromal rejection, loosened sutures, wound dehiscence. normal pattern topography transparency restored, UCVA BCVA improved significantly, astigmatism slightly. There no statistically significant decrease EDC. Conclusion Our early results indicate that could improve pathology. This approach shows promise as safe effective surgical choice treatment
