  • The Xen45 implant was launched in Malaysia by Allergan at the Conexxion@Nexus in Kuala Lumpur on 22nd September 2016. 
  • This Xen45 is designed as a simple Minimally Invasive Glaucoma Surgery (MIGS) implant for mild to moderate glaucomas.

  • Inserted through the cornea, the tube is injected to lie between the anterior chamber and subconjunctival space, where it drains aqueous.

  • Although the procedure looks simple, there seems to be a learning curve involved. 
  • It is also not clear what complications commonly occur and of course, the long term results are yet to be known. 

  • According to Dr Chelvin Sng, nearly 20% of the cases require needling at some stage.

  • It can be done during phacoemulsification as a one step procedure.

  • (A suggestion: Would injection of a little BSS in the area where the Xen is supposed to come out, to balloon the conjunctiva, reduce the rates of conjunctival perforation ?) 

  • The Xen45 will be available in the Malaysian market by next year.
