XENIA IMPLANT - THE STORY SO FAR

To study the long term effects of Xenia Implant in restoring normal anatomy of cornea in patients suffering from keratoconus and Post Lasik ectasia

Xenia Implant made from porcine collagen and supplied by Gebauer

Optimax Lser Eye Clinic, Leicester, UK

Prospective study of keratocnus and post lasik ectasia patients who underwent Xenia implantation over a period of 2 years

10 eyes of 10 patients

Intralase Femtosecond Laser stromal pocket created at 100 to 130 microns deep, 8.7 mm dimater, 3.7 mm access port. Gebauer Lenticule of varying thicknesses were used (75 to 120 microns) Pre and post operative vision, corneal thickness, corneal curvatures were measured. Antibiotics and steroid eye drops were used postoperatively

 

Average cornea thickness increased from 350 to 513 microns; average corneal astigmatism decreased from 7.4 D to 2 D. Unaided vision improved from 1.74 LogMar to 1.54 LogMar

Tkicker Xenia implants have a tendency to opacify while thinner version remains transparent

Keratoconus and post lasik ectasia patients have only a few treatment options of which Xenia Implants seems to offer promising results

The newer version of Xenia (75 microns) tends to remain transparent resulting in better visual outcome
