LASIK (LASer-assisted-In-situ-Keratomileusis) surgery is the most common form of laser eye surgery. It is used to treat short-sightedness and long-sightedness – with or without astigmatism. Many patients prefer it because of the rapid healing, with very little discomfort, and rapid visual recovery and stability.










At the Sheffield Vision Centre our preferred lasik treatment is 'all-laser-LASIK'.  Here our Zeiss Visumax femtosecond laser is used to create the LASIK flap, then our Mel90 excimer laser precisely reshapes the underlying cornea to give the desired refractive result.

Your Eye is anaesthetised with eye drops and a lid speculum is gently positioned to prevent you from accidently blinking. A thin flap of corneal tissue is then created with the femtosecond laser and folded gently back. The excimer laser is then applied for a few seconds to accurately reshape the inner cornea that has been exposed. This layer is then rinsed and the flap is carefully repositioned.

The whole treatment usually takes between 15 to 20 minutes, the actual laser is in operation for only a tiny fraction of this time, and after a quick post operative check by your surgeon, you are free to go. The recovery from Lasik is generally quite comfortable and the visual recovery quick. You will have navigational vision when you get up off the couch but it is always wise to take a few days off after your surgery. Follow up appointments are generally the next day, then between 7 and 14 days, then 1-3 monhs and then 6 months later. We tend to judge the success of LASIK treatment at about 4-8 weeks but you should have good vision well before that. We will keep a check on your progress for at least 9 to 12 months.

We frequently use PRESBYOND® Laser Blended Vision when we undertake LASIK in the over 45s.  This treatment, developed in conjunction with Carl Zeiss uses 'micro-monovision' combined with manipulation of 'spherical abberation' to reduce the need for reading or bifocal glasses in this age group.  If you are interested in PRESBYOND or just in LASIK in general, please contact us for more information.
