TitreThe Zeiss VisuMax Femtosecond laser as a Flapmaker and as a Refractive tool.
ButTo discuss technical features, applications, results of the Zeiss scientific study group and early personal experience using Zeiss VisuMax Femtosecond Laser
MéthodesThe VisuMax Zeiss Femtosecond laser makes a very precise corneal flap in preparation of laser surgery with the Mel 8o laser using an ergonomic pivoting patient bed -and can perform FLEX: Femtosecond Lenticule Extraction for correction of refractive anomalies. With FLEX, instead of ablating tissue, the VisuMax excises tissue with a precision of 2 micron in order to obtain the planned refractive change. Other Refractive applications of the VisuMax are: creating tunnels for Intacs, performing incisions for A.K and LRI.and performing Penetrating and Lamellar keratoplasty and Dsaek
Complicated cases such as retreatments -surgery after RK and in very steep and flat cornea’s will be discussed.
RésultatsPrecision of the VisuMax equals the resolution of OCT measurement=3 Mikron.Flap thickness had a SD of +/_7 Micron.
12 months follow up of Refractive outcomes for myopia are 98%+/- 0, 5 d obtained- intended using the classical ablation approach and 93% using the Flex technique. At 6 months 98 % of eyes were 10/10 (20/20) uncorrected in both series.
Not one eye lost more than one line of Bscva.No complications were encountered in all series. Patient satisfaction was very high. The stability over a 6 month fup was excellent with less than 0, 1 Dptr.change.
ConclusionThe VisuMax Zeiss Femtosecond laser revolutionizes refractive surgery with a new extremely safe and less invasive approach -FLEX -Excision instead of ablation. The VisuMax is an extremely accurate flapmaker and a marvellous tool for Keratoplasty
