My base prescription was around -9.00 in both eyes with high astigmatism and I had worn gas permeable lenses for 15 years. I am now 6 days post op and as far as I can tell, the sight in my left eye is already perfect and although my right eye is perhaps still a little short-sighted (no more than, say 0.5 a dioptre) the quality of vision is improving daily.
The Optegra facilities themselves were top noch (certainly more modern than Moorfields, where I had also had a consultation), with what I understand to be the latest technologies. Rob Morris (surgeon) was excellent - friendly, plain speaking and clearly experienced in LASIK.
Although relatively early days yet (esp. with my prescription) Rob believes that my sight is likely to be excellent in both eyes, within a couple of weeks.
I Would thoroughly recommend Optegra!!!
