| Titre | 90 and 80 micron flaps in LASIK with the Ziemer LDV Femtosecond Laser. |
| But | The Ziemer LDV femtosecond laser delivers small, low energy pulses at a much higher frequency than conventional femtosecond lasers in a precise cutting plane. To estimate the predictability of the thickness and the size of flap cut by the LDV laser in 150 eyes when using the 90 InterShield spacer foil and in 25 eyes using the 80 foil. To evaluate the quality of the stromal bed and the safety of the procedure in recording complications and visual results. |
| Méthodes | Since January 2008- using the Ziemer LDV femtosecond laser in performing LASIK for the treatment of myopia or hyperopia - 150 eyes were cut using the 90 Interspace foil (90 group) and 75 eyes using the 80 foil (80 group) with an intended flap thickness of 90 and 80 µ. Preoperative flap thickness, flap size and hinge size were measured and the quality of the stromal bed was recorded. The laser treatment was done using the WaveLight Allegretto Eye Q-400 excimer laser. UCVA and BCVA were recorded at day 1 and at 2 months. |
| Résultats | The mean flap thickness was 89.29 ± 11.71 microns in the 90 group and 82.21 ± 6.43 microns in the 80 group. The flap diameter was 9.56 ± 0,27 mm for both groups. Bed quality was excellent in most cases. In the 90 group no clinically relevant complications occurred during surgery. In the 80 group 2 cases of adhesions needed an immediate recut, in one eye a pseudobuttonhole occurred. Visual recovery observed on day one and 2 months and the visual results were similar to conventional LASIK. |
| Conclusion | The Ziemer LDV femtosecond laser offers a high-degree of precision in the creation of 90 and 80 micron flaps in LASIK. In the 90 group no clinically relevant complications occurred during surgery. In the 80 group some minor complications did not result in a significant visual loss. |
