other procedures

LASIK is an effective surgical procedure to lessen or eliminate your dependency on glasses or contact lenses.
However, other types of eye surgeries are available to treat certain vision problems. It is important to remember
that each of these LASIK alternatives is specific to a certain group of patients and may not be appropriate in your
particular situation. These include:

PRK (photorefractive keratectomy)
Intracorneal rings
Phakic intraocular lenses
Refractive lensectomy
RK (radial keratotomy)
AK (astigmatic keratotomy)

Another alternative is to simply continue wearing your glasses or contact lenses.

PRK
PRK is a laser procedure used to treat some of the same conditions as LASIK. It is an option for people whose corneas are too thin for LASIK, or whose eyelids are too narrow for the microkeratome to be placed. Instead of
making a flap in the cornea, PRK actually removes the top layer of the cornea, called the epithelium, and the
laser is used to reshape the eye.

Because no flap is created, PRK does not have any possible flap complications. However, PRK does carry a
higher risk of haze or scarring; for people who need a greater correction, sometimes original successful results
can decrease over time. PRK also requires a longer recovery period, usually 7 to 10 days, and patients may
experience more discomfort during healing.

Intracorneal Rings
Placing intracorneal rings into your cornea is a procedure to correct low levels of nearsightedness or myopia.
This surgical procedure does not correct astigmatism or farsightedness (also called hyperopia), and can only be
used in patients with small pupils.

Phakic Intraocular Lenses
Phakic intraocular lenses (or phakic IOL) are a good option for patients who are very nearsighted or very
farsighted. In this procedure, a permanent corrective lens is placed inside the eye. These implantable contact
lenses are fairly new, so the long-term results from this procedure are not yet available.

Refractive Lensectomy
Refractive lensectomy involves removing the natural lens in the eye and replacing it with a plastic lens. This
operation is essentially the same as that done for older patients who develop a cataract, which is a clouding of
the natural lens. In both situations, patients elect to have the lens implant to improve their vision and decrease
their dependency on glasses. Refractive lensectomy is used especially for cases of high myopia and high
hyperopia. It is a relatively complex procedure, as it involves going into the eye, and has a different set of potential
complications, including:

Bleeding and infection inside the eye
Retinal detachment
Other potential serious problems

RK and AK
RK is an incisional procedure for nearsightedness. This is an older procedure that can produce very good results, but it has lost popularity due to the fluctuations patients experience in their vision after
the procedure. Compared to PRK and LASIK, the outcomes are generally less reliable.

AK is a procedure to correct astigmatism, and is sometimes performed along with other eye
surgeries, such as cataract surgery and LASIK. In AK, incisions are made in the outside part of
the cornea to correct astigmatism. Because of the location of the incisions, AK provides a
correction of astigmatism in most cases without fluctuations in vision. There are very specific
requirements to be a candidate for AK, which Dr. Dodge can discuss with you.
