PRK and LASIK Surgeries Post 2

Costs
Of course, the cost of this procedure varies from region to region and from doctor to doctor. In determining a fee for this procedure, clinics take into account administrative costs, maintenance costs, pre- and postoperative time spent with the patient, as well as postoperative medications. The average cost is estimated to be anywhere from $1,200 to $2,500 per eye. The cost of this procedure, however, is dropping. The cost for the LASIK procedure tends to be a bit more because more equipment is used.

PRK

Procedure
The outpatient procedure takes about 5-10 minutes per eye. Drops are applied to the eye as an anesthetic. In order for the eye to remain open throughout the whole procedure, a device called speculum is placed over the eye. A laser, called an excimer laser, is used to remove accurate amounts of tissue from the cornea.

Risks
About 1-2 percent of patients will get an infection or a hazy cornea after the procedure. Serious complications are extremely rare. Infection can usually be eliminated with antibiotic medications. Other possible problems include delayed surface healing and or scarring, over- or under-correction, and the development of astigmatism. These, and other problems can usually be treated with antibiotics.

LASIK

Procedure
Like PRK, LASIK procedure takes about 5-10 minutes. A suction ring is placed over the cornea of the eye after anesthetic eye drops are applied. The LASIK procedure uses two devices: the microkeratome and the excimer laser. The microkeratome is a mechanical “shaver” that moves back and forth at an excessive rate. The suction ring contains “guide tracks” that maintain an accurate path for the microkeratome. The microkeratome lifts the cap of the cornea, with a portion of the cornea left in tact to provide a hinge. The suction ring and the microkeratome are then removed. The middle portion of the cornea is exposed after the flap of cornea is folded back. Tissue is then removed and the center of the cornea is reshaped using the excimer laser. The hinged flap of cornea is folded back into its original location.

Risks
The side effects of the LASIK procedure are similar to those of the PRK. The most common side effects are temporary light sensitivity and halos. This is usually temporary. Infections can occur as well. This is an extremely rare occurrence. Antibiotics are usually used in the postoperative period.

20/20 Guarantee?

People eager to indulge in the dream of having 20/20 vision without glasses and contacts will be disappointed. As a matter of fact, almost all post-surgery patients still need to wear their contacts or glasses for night driving and reading.

Is it right for me?
Unfortunately not everyone can be a candidate for laser eye surgery. Since eye prescriptions fluctuate throughout adolescence, it is essential that a potential patient be at least 21 years of age and maintain the same prescription for about a year. Likewise, a candidate must not be pregnant or nursing at the time of the surgery. It is also important to take note of the fact that each person will react to the surgery differently depending on his or her healing process.

Subsequent surgery may be required for some people who have extremely high prescriptions and large pupils. They are also most likely to have night vision disturbance and dry eyes. Again, it is imperative to openly discuss these issues with the surgeon.
