Surgery to improve your eyesight is known as "refractive surgery" or "vision correction". There are 2 different types: laser eye surgery and lens surgery.
Both types of surgery can make you less dependent on glasses or contact lenses. Research shows that both are safe and effective.
According to the Royal College of Ophthalmologists, more than 95% of people who've had refractive surgery are happy with the results.
What type of refractive surgery will suit you best depends on a range of things, including your eyesight, eye health, age, budget and lifestyle.
Your surgeon will examine your eyes, assess your needs and help you decide on the best option for you.
When weighing up the risks and benefits of refractive surgery bear in mind that wearing contact lenses also carries some risks for your eye health.
See more about contact lens safety.
Refractive surgery is not available on the NHS for people who just want to improve their eyesight.
Most people have it done at a private clinic. Costs vary according to what kind of surgery you're having.
Laser eye surgery, or laser vision correction, involves using lasers to reshape the front surface (cornea) of your eyes so that you can focus better. It can correct short-sightedness, long-sightedness and astigmatism.
Laser eye surgery is suitable for most people over 18. Ideally your eye prescription will have stayed more or less the same for about two years. Lens surgery may be more suitable if you have a high spectacle prescription or later in life.
There are 3 main types of laser eye surgery: LASIK, SMILE and surface laser treatments.
All 3 types of laser eye surgery have similar results. Your surgeon will talk through your options with you and help you decide on the most helpful one for you.
About 1 in 10 people who have laser eye surgery need more surgery to get the best possible results. There's usually no extra cost for this.
Common side effects include:
Severe loss of vision is very rare.
See more information from the Royal College of Ophthalmologists about laser vision correction (PDF, 436kb).
There are 2 main types of lens surgery: phakic intraocular lens (PIOL) surgery and refractive lens exchange (RLE).
With PIOL artificial lenses are placed in your eyes without removing your own natural lenses. It's a bit like building contact lenses into your eyes.
Because the lens is inside your eye, you can do things you couldn't normally do in contact lenses, such as swimming or water sports.
PIOL can be a good option for younger people who are not able to have eye laser surgery, perhaps because they have a high eye prescription or a high degree of astigmatism. Later in life, RLE may be a better alternative.
The surgeon makes a small cut in the surface of your eye and slips the news lens in through this. No stitches are needed.
Your surgeon will discuss any side effects and risks with you before you go ahead with surgery.
It's normal to get some disturbance in your vision after PIOL but this should gradually settle down. Glare from oncoming headlights while driving at night is common to begin with.
The surface of your eye may feel uncomfortable for a while. You may also have red blotches on the white of your eye for few weeks.
Serious complications are rare and, if you do have any problems after surgery, they can usually be corrected. Cataracts (when the lenses in the eyes become cloudy) may develop earlier in life after PIOL.
See more information from the Royal College of Ophthalmologists about PIOL (PDF, 446kb).
RLE is basically the same as cataract surgery. The natural lens in your eye is removed and replaced with a new, artificial one.
RLE may be a good option if you're older and you are not suitable for laser eye surgery, perhaps because you have a high eye prescription or have the beginnings of cataracts.
There are 2 different types of artificial lens used for RLE: monofocal and multifocal.
Most people have some visual side effects and discomfort in the weeks or months after surgery but these should gradually settle down.
Serious complications are more common after RLE than after laser eye surgery or PIOL surgery. About 1 in 500 people have significant loss of vision after RLE.
Your surgeon can tell you more about the risks before you go ahead with surgery.
See more information from the Royal College of Ophthalmologists about RLE (PDF, 459kb).
