LASER EYE SURGERY
LASIK & ADVANCED SURFACE TREATMENT (LASEK)
More than 50 million people are now enjoying the results of LASIK and LASEK laser vision correction. You can hear some of their stories by clicking here. We only do ALL LASER laser eye treatment with no blades. This treatment is best for you if you are aged between about 20 and 50. If you're older then lens replacement is usually a better solution. Our strategy for giving you the best result we can is by:
1. Getting accurate information about you and your eyes
Your lifestyle, eyes and vision are unique. We measure thousands of points on the surface and inside your eyes using high tech scanners. Each scan only takes a few seconds and they help us to decide on a customised, personal treatment solution that's best for you, your eyes and your lifestyle.
2. Surgeon Mark Wevill discusses your lifestyle, examines your eyes and agrees a personal, customised treatment plan with you
Mark's been correcting vision for 20 years with intraocular lenses and lasers, is a Fellow of the Royal College of Surgeons of Edinburgh and has been invited to speak to surgeon colleagues at over 20 national & international surgeon congerences. Read more here.
LASIK is a 2 stage procedure. We don't use any blades. First a thin flap is made on the surface of your eye using the only Zeiss Visumax femtosecond laser in Birmingham and it's the most gentle and comfortable femtosecond laser of all. Each laser pulse lasts a femtosecond (which is one billionth of one millionth of a second) and is accurate to within a few microns (1/1000 of a millimeter). The second stage accurately reshapes your cornea with the B&L or latest Zeiss Mel 90 laser using precision optics for which Zeiss is so well known. The whole treatment takes less than 10 minutes and most people can drive by the next day.
LASEK, also known as advanced surface treatment, is also a 2 stage procedure and is better for some eyes, sports and occupations. First the surface epithelial layer of the cornea is loosened and removed. Then the underlying surface is reshaped using the same B&L or Zeiss Mel 90 vision correction laser used in LASIK. Once again no blades are used but no flap is created. The treatment is quicker but the recovery is slower than LASIK. Mark will advise you which treatment is better for you.
QUESTIONS & ANSWERS:
How long do the results of laser last, does the laser "wear off"?
The effects of the laser on your cornea are permanent, it can't "wear off". But your eye can change especially as you age which can change the overall focus of your eye again. When the lens in your eye ages (called presbyopia) you'll need reading glasses, but there are treatment options for this too, including multifocal intraocular lens surgery and monovision laser treatment.
Do optometrists and eye surgeons have laser eye surgery themselves?
Yes, over 90% of refractive surgeons have recommended or performed refractive surgery (surgery to replace glasses) on their immediate family members. And refractive surgeons are approximately five times more likely than the general public to have refractive surgery on their own eyes. (Scientific journal publication). Mark Wevill has recommended and done refractive surgery on fellow surgeons, optometrists, friends and family, including his sister and wife.
Which celebrities and sports people have entrusted their eyes to laser eye surgery?
There is a very long list which includes Sir Elton John, Brad Pitt, Tiger Woods, Vijay Singh, Kim Kardashian, Richard Branson, Jessica Simpson, Nicole Kidman, Cindy Crawford, and many others. Mark has treated celebrities who do not want to be named.
What are the risks of laser eye surgery?
All treatment carries risks which must be carefully considered before having the treatment. The risks will be extensively discussed at your consultation, but here are some of the more common and severe risks. A severe infection can cause corneal scarring (about a 1/10,000 risk). A more common, but less severe risk is an over or under response which occurs in less than 5% of treatments and occurs because we're all different, we don't all heal the same and another "fine tuning" treatment may be necessary. Some people develop dryness of their eyes afterwards especially if their eyes are dry in contact lenses before treatment. This usually improves quickly with eye drops but occasionally the eye drops are necessary for a long time. And you can be sensitive to light afterwards. You are less likely to have halo's and glare at night after laser eye surgery than with older lasers. A review of 97 scientific publications and 68,000 eyes concluded that advances in laser technology have improved results significantly and only 1.2% of people were dissatisfied with the results of their laser eye surgery (Scientific journal publication).
What is wavefront?
Photographers and astronomers minimise blur from aberrations with special lenses to take crisp, clear photographs or see distant stars and planets more clearly. If you need glasses, then most of the blur in your vision comes from having myopia, hyperopia or astigmatism. However wavefront errors or aberrations aren't corrected by glasses or contact lenses and can cause some blur. Conventional lasers worsen aberrations while advanced, wavefront-enabled lasers can treat these aberrations.
