LASIK eye surgery is intended for correcting myopia (nearsightedness), hyperopia (farsightedness) and astigmatism (blurred image caused by an imperfection in the curvature of the cornea).During the procedure, an ophthalmologist (eye doctor/specialist) uses a laser to reshape the cornea making vision permanently clear. While this may seem like a simple procedure and the ultimate solution for any bespectacled person, LASIK should only be considered once you are totally aware of all aspects relating to this eye procedure.

The Pro’s – Advantages of LASIK

According to the American Academy of Ophthalmology (AAO), LASIK eye surgery has a 90 percent success rate and the procedure has a “low” rate of complications and a “high” rate of satisfaction. Some of the pros include :

High Tech & Quick Procedure

It is a fairly safe, and effective procedure in which a laser, guided by a computer, very precisely and accurately corrects the curvature of the cornea. Performed as an outpatient procedure, LASIK eye surgery takes about 10 to 15 minutes for each eye and it is relatively painless.

Short Post-Operative Recovery

Immediately after surgery a patient may experience a sense of burning, itching or a feeling that something is in the eye, this usually settles within a day. Vision may appear blurry or hazy but it improves by the next day.

Painless & Low Risk

Pain and discomfort is minimal and this is of great advantage for the patient. Since a local anesthetic is used, the patient is awake and aware, without fearing any complications from general anesthesia.

Good Prognosis

Complete recovery of a patients vision is very individualistic but it may take anything from 2 weeks to 6 months for a patients vision to stabilize. Overall Lasik surgery is a painless, quick procedure, recovery occurs relatively quickly and vision is restored in most patients.

Convenience and Comfort Over Other Corrective Methods

Wearing glasses offers many restrictions for patients, peripheral vision is obscured, there maybe a glare or reflection, glasses require a frame that maybe also be expensive. Contacts lenses allow for increased chances of getting infection and are high maintenance therefore one of the greatest benefits of Lasik eye surgery is that vision is corrected and the patient no longer requires the use of glasses and contact lenses, greatly improving the patients quality of life.

Self Esteem

Improving a patient’s vision can assist boost one’s self – confidence, because poor vision can affect participation in certain sports, traveling, arts and crafts and glasses and contacts are impossible to wear or they can be cumbersome in these activities. Many people are also self conscious of wearing glasses and this affects their social and professional life, Lasik eye surgery greatly improves their situation.

The Cons – Disadvantages of LASIK

In most cases, the disadvantages of LASIK may seem fairly insignificant compared to the advantages for those living with glasses. However, both aspects should be considered for making an informed decision.

Cost of LASIK

One of the major disadvantages of LASIK eye surgery is that the cost of a corneal scan and assessement, the LASIK procedure itself as well as post operative care may not be affordable for many patients . A patient is expected to visit the ophthalmologist regularly and in some instances repeat surgery is required because the initial surgery did not produce an optimum level of vision correction. All of this is done at an additional cost to the patient. LASIK eye surgery is considered as being a cosmetic surgery and many medical insurance plans do not cover the cost of the surgery.

Irreversible Procedure

Changes made to the cornea by LASIK eye surgery cannot be reversed and the results are not always guaranteed. Some patients may experience a glare or halo around images, difficulty driving at night, fluctuating vision and dry eyes. Patients who have LASIK eye surgery may require prescription glasses as they get older and their vision deteriorates.

These are the main disadvantages of LASIK eye surgery and while they may not often occur, it is nevertheless important to consider these possibilities. The final decision for or against LASIK eye surgery should be made by the patient, without coercion from the practitioner or staff, and for this reason, informed consent is a prerequisite before any patient undertakes the procedure.
