Questionnaire: In the meantime, we are routinely conducting routinely perforating keratoplasties, endothelial transplants, and tunnel prunctions prior to implantation of ICRS (= intracorneal ring segments) with femtosecond laser Femtec (20/10 Perfect Vision, Heidelberg). Whether this innovative technology can actually set a new standard for the respective operations, we will provide detailed information. Whether the successful surgery will also result in stable postoperative patient data for the long term, we will postoperatively follow the pKPL with 18-month data postoperatively and post-operative with the Keratokonus treatment with ICRS implantations with 24 month data. Method: By means of casuistics and video sequences, we are able to carry out the respective operation, take into account the advantages of the improved Femtec fs laser in the operative procedure and report on long-term postoperative results in pKPL and keratoconus treatment. Results: After the pKPL had been performed, we were able to measure a significantly improved visual acuity between 0.25 and 0.35 postoperatively for 12 months. The transplants were well adapted in the long term to all patients. In one patient, we found discrete descemetals, and in a further patient we observed discrete incidences. After successful endothelial transplantation (DLEK), we found a clear cornea 1 month postoperatively and only a few striae on the endothelial side. After implantation of the ICRS, all patients also showed a significantly flattened keratoconus and significantly reduced astigmatism up to 24 months postoperatively. In all patients an improvement in the visual acuity was observed by approx. 50%. Conclusions: Our previous interventions as well as the long-term postoperative results show that the technology of the femtosecond laser can only be used successfully and successfully. The new standard for pKPL also shows good postoperative results in the long term. Another new standard is the use of this innovative technology in performing endothelial transplantation (DLEK). Individual parameters can be taken into consideration during the pruning of implantation tunnels. The implantation of ICRS is performed under optimal conditions and results in long-term postoperative results.
