CONDUCTIVE KERATOPLASTY (CK)
How it works: CK is a non-laser vision correction
technique that was approved by the FDA in April of 2002. A low-energy, high
frequency radio current is applied directly to the periphery of the cornea.
This technique is done manually by the physician with a metal tip that
conducts the current. The application is patterned in such a way that it steepens the central cornea in the far-sighted patient.
Who can benefit: A farsighted patient over 40 is the
best candidate for CK. The patient should be between +0.75 and +3.00 diopters
of correction and have less than .75 of astigmatism.

PHAKIC INTRAOCULAR LENSES
|
|
| |
How it works: The procedure, Phakic IOL is
currently under FDA investigation. It involves the use of an
implantable, synthetic lens and may be used either in front of or behind the
iris.
Who can benefit: This procedure works best for patients
with either high levels of nearsightedness or farsightedness. The
advantages of the Phakic IOL include instant vision correction and the lens
may be removed or replaced at any time.

INTRASTROMAL CORNEAL RING SEGMENTS (INTACS)
 |
| Intacs can be removed or replaced at any
time. |
How it works: Intacs
is a non-laser FDA approved procedure for the benefit of the mildly
nearsighted patient. It involves implanting two tiny plastic arcs in the
cornea. These crescents are placed in the outer edge of the cornea and
opposite each other. This procedure actually helps to flatten the cornea.
Who can benefit: This procedure is best for a patient
with a mild degree of nearsighted error with little or no astigmatism. This
procedure is also reversible. More...
See Intacs for Keratoconus in Technology and Research.
CLEAR LENS EXTRACTION (CLE)
 |
| |
How it works: Clear Lens Extraction is similar to cataract surger. Both
require the removal of the eye’s natural lens and replacing it with a
synthetic lens. There are different lens options to correct either distance
and/or near vision with an option for those with astigmatism.
Who can benefit: The best candidate for this
procedure is someone who is very farsighted. However, this procedure
may be used on patients with low levels of farsightedness and also for high
levels of nearsightedness. More...
PRELEX (PRESBYOPIC LENS EXCHANGE)
How it works: Prelex is similar to
the Clear Lens Extraction procedure. The difference is the use of a
multifocal intraocular lens to correct vision for those patients who are
presbyopic. Refer to Glossary Link, (presbyopia).
Who can benefit: The best candidate for Prelex is the
farsighted patient with presbyopia. Patients with high levels of
nearsightedness can benefit as well.
