lasik risks

Hazards during LASIK surgery occur at a relatively low rate of 3 to 5 percent of all cases ; However, it is important to be aware of all the risks of LASIK that may occur during this procedure when considering this surgery. Rate risk has declined steadily since the late 1990s, with the most experienced surgeons and new advances in LASIK technology that improves the results of this procedure.

General confidence has also increased because of the high success rate of this procedure as indicated by the U.S. military , who used this surgery favorably since 2000 to reduce the need for glasses and lenses bulky contact. Over 16,000 soldiers have undergone LASIK surgery , the number of risks to LASIK surgery were small , studies show that 86 % had visual acuity of 20 /20 or better without glasses or contact lenses and 98% achieving vision of 20/ 40 or better without glasses or contact lenses.

The Ophthalmology February 2005 also stated that the side effects associated with patients in this study were rare. Most of the risks associated with this type of surgery can be corrected, and the LASIK procedure is considered one of the safest for operations. And on a final note, you can consider the fact that the rate of serious complications for users of contact lenses is 3% , so with complications such as corneal abrasions , conjunctivitis papillary , and more often require surgery to treat . For more information on the risks for LASIK , please see the list below:

During the correction / Under Correction

LASIK can correct and reshape the cornea to some extent , even with the most advanced technology and experienced surgeons are available today ; although this is often sufficient for most patients , will be a number of cases in which most of the correction or under-correction results . In these cases, these patients are usually required to wear weaker glasses or contact lenses after surgery.

Irregular Flap / Flap wrinkles

During the surgical procedure LASIK , a flap is created to remove an amount of corneal tissue and re - shape of the cornea ; this component is closed after being re -shaped cornea - and naturally adheres after closing. However, if the flap is not cut correctly either , or cut too thin or thick, it may not adhere properly and smoothly, but it may wrinkle . Other causes of wrinkles flap include the patient to close his eyes tightly during the first day after surgery. In general, however , there is a rare complication , occurring in less than one percent of all cases ; if there are no such problems occur as a result of this ride then it is fixed in most cases by re - treatment and surgery. However, there are a number of additional problems that may result from flap wrinkles or irregular component requiring other types of treatment :

1 - keratoconus. It is a condition resulting from a section cut too deep or too much tissue when the shape of the cornea is removed during the LASIK procedure, causing swelling of the surface of the eye and distort the patient's vision . Unfortunately, these conditions can not be treated with laser enhancement , and hard contact lenses or implants may be necessary to maintain a regular cornea.

Two irregular astigmatism - . This may be the result of a shock resulting from an increase in flap and create the irregular surface of the cornea. This condition is characterized by double vision, also known as diplopia, and treated with additional laser surgery .

3 islands of the central cornea - . This is a condition which results in the cornea is not eliminated in a uniform manner , resulting in small pieces of tissue from the cornea to the corneal surface . Although this complication usually heals in a few months , further improvements may be necessary or contact lenses to smooth the surface of the cornea.

4 Halos and sparks - they affect the night vision of patients as they are at night looking at the bright lights, and are characterized by blurred images with circles from the center . ; if it is not treated, it can prevent the patient from driving at night . Although often heal within two months , glasses or additional surgery may sometimes be necessary to correct them.

5 visual regression - . This condition is characterized by visual darkness and loss of visual clarity , and usually heals in the first three months after surgery.

Diffuse lamellar keratosis

This condition follows from the cellular debris that may have been loosened LASIK surgical procedure and embed within the corneal flap , creating inflammation below the lid , as the cornea reacts to the presence of these foreign groups. Scarring can occur in rare cases , resulting in a permanent loss of vision if not treated immediately with antibiotics ; This condition can also be treated with additional surgery to lift the flap and remove the inflamed cells .

Infection / inflammation

Any surgical orocedure contains the resulting and LASIK surgery is no exception risk of infection and inflammation. Antibiotic eye drops are commonly prescribed after all LASIK to prevent infection , and they kill most bacteria that may have entered the system through surgery . If infection of the patient does not respond to antibiotic drops and then the anti- inflammatory drugs such as steroids can also be prescribed.

The epidermal growth

This is one of the rarest of all the risks occur during LASIK surgery , which occurs when the cornea epithelial cells grow out of control under the flap of the cornea to the point that alter or affect vision ; This is treated with surgery that removes cells that grow inward beneath the flap . This complication occurs in less than 1 percent of all LASIK surgeries .

In 2006, a study that concluded that contact wearers are at a greater risk of infection was made that people who have had LASIK surgery. Over the past 10 years, more than 3 million people have experienced the benefits of Lasik with nearly perfect results . Would you be one of them ?
