Do You Need Refractive Surgery?

 

Refractive eye surgery is very important non-invasive eye surgery designed to increase the refractive condition of your eye and reduce or even remove dependence on eyeglasses or contact lenses. This can involve different techniques of cosmetic surgical repositioning of your eye's iris, lens placement or lens replacement. It may also mean that your eye is reshaped so that the eyesight is improved. It is also called LASIK (low-amplitude refractive surgery) or PRK (high-amplitude refractive surgery).Chick here for more details about chirurgia refrattiva

As the term suggests, refractive surgery alters the natural shape of the eyeball and thus reshapes the corneal surface of the eye. Some of these procedures include LASIK (lower-eye-laser keratomileusis), PRK (presbyopia replacement) and LASEK (lower-Lasek eye correction). As there are many different techniques involved in refractive surgery, some people may have to undergo several surgeries before they find one that works for them.

One of its major advantages is that it can be performed without the help of an eye doctor or even a qualified eye care professional. In fact, the patient will have to do most of the required preparation for the surgery, including wearing eyeglasses, contact lenses and even making use of contacts while at home. However, this is one of the major drawbacks of refractive surgery: There are no guarantees that the procedure will lead to an improvement in the patient's vision. Many factors such as age, lifestyle and health conditions can affect the vision of people. Hence, these factors need to be carefully considered and taken into account before undergoing refractive surgery.

As mentioned, refractive surgery can involve the reshaping of your eye by reshaping the corneal surface. Some of these procedures involve removal of the uppermost portion of the iris or the whole cornea and replacing it with an artificial lens or a bifocal. These methods can be used as part of the PRK method or in LASEK. In other cases, there is only one eyelid that is removed, or a flap of skin is lifted to make room for the implant. {to be fitted onto the corneal surface. Sometimes the entire iris or even the entire cornea is removed.

While these corrective surgeries are not permanent in nature, they are quite effective. The main problem with refractive surgery is that the patient must have to wait for several months or even years before results show up, and then he or she has to wait again for a few more months or even years to see some visible results.

On the other hand, LASIK and PRK can bring about long-term results, because the eye surgeon can perform both operations simultaneously. The surgeon may also use laser technology to reshape the eyesight for patients who suffer from nearsightedness or farsightedness, as well as for patients who need correction of astigmatism.
