Refractive surgery is a variety of eye surgery that can correct refractive errors such as nearsightedness, farsightedness, and astigmatism. These errors occur when the form of the cornea (the clear front the main eye) is not bent correctly, that causes light to concentrate incorrectly on the retina (the light-sensitive tissue in the rear of the eye). Refractive surgery reshapes the cornea to improve the way light is focused, so that you can see more clearly without glasses or contact lenses.

There are several different types of refractive surgery, each with its own advantages and drawbacks. The most common types are:

LASIK (laser-assisted in situ keratomileusis): This is the most popular type of refractive surgery. It uses a laser to manufacture a flap in the cornea, and then an excimer laser is used to reshape the underlying corneal tissue. LASIK is generally considered to be effective and safe, with a high success rate. However, it can also cause side effects such as dry eyes, glare, and halos.

PRK (photorefractive keratectomy): This type of surgery uses an excimer laser to remove a thin layer of tissue from the cornea. PRK is less intrusive than LASIK, but it can also be more painful and have a longer recovery time.

SMILE (small incision lenticule extraction): This is a newer type of refractive surgery that uses a femtosecond laser to manufacture a lenticule (a small part of corneal tissue) in the cornea. The lenticule is then removed via a small incision in the cornea. SMILE is generally considered to be less intrusive than LASIK or PRK, with a shorter recovery time and fewer side effects.

RLE (refractive lens exchange): This type of surgery involves removing the natural lens of the eye and replacing it with an artificial lens. RLE can be used to correct refractive errors in people who are bad candidates for other styles of refractive surgery, such as people with thin corneas or dry eyes.

The best type of refractive surgery for you will depend on your own needs and preferences. Your eye doctor can help you decide which sort of surgery is right for you.

Risks and benefits of refractive surgery

Different types of refractive surgery have some risks, but the risks are generally low chirurgia refrattiva migliore in italia. Some of the potential risks of refractive surgery include:

Dry eyes

Glare and halos

Undercorrection or overcorrection of the refractive error



Delayed healing

Visual trouble

The benefits of refractive surgery include:

The ability to see clearly without glasses or contact lenses

Improved quality lifestyle

Increased self-confidence

When to consider refractive surgery

Refractive surgery is a good option for those who are tired of wearing glasses or contact lenses and who are looking for a permanent solution to their refractive error. It is also a good option for those who have difficulties wearing glasses or contact lenses because of their lifestyle or profession.

However, refractive surgery is not right for everyone. People who are bad candidates for refractive surgery include:

People with certain eye diseases, such as glaucoma or macular deterioration

People with thin corneas

People with dry eyes

People who are pregnant or breastfeeding

Before you decide to have refractive surgery, it is important to speak to your eye doctor about the risks and benefits of the process. You should also make sure that you are a good candidate for the procedure.
