Lasik Eye Surgery With Fewer Risks Using IntraLase
Bianca Tavares
The introduction of laser eye surgery a number of years ago -
first via the PRK procedure and then using LASIK (an acronym for
Laser Assisted In-situ Keratomileusis) - marked a major step
forward in vision correction without having to wear eyeglasses
or contact lenses.
Whilst the LASIK procedure has proven very popular with millions
of successful operations carried out around the world, there has
always been a slight risk of an unsuccessful operation or of
complications. These risks are primarily associated with the
first stage of the operation in which a hand-held microkeratome
blade is used to create a corneal flap. This flap is of vital
importance to the overall success of the operation. If it is too
thick or too thin or incorrectly shaped it could adversely
affect the quality of vision.
Advances in laser technology have now made it possible to reduce
the risks associated with LASIK eye surgery through a procedure
known as IntraLase. The IntraLase procedure performs the first
crucial part of the operation without use of a blade and as such
improves on the safety, precision and outcome of traditional
LASIK surgery.
With IntraLase, the corneal flap is created by the surgeon using
a computer-guided laser with great precision, enabling the
surgeon to have exact control over its dimensions. Accuracy is
achievable within the range +/-10 microns. The result being that
the flap can be tailored to meet the precise needs of each
individual patient. It even means that patients who aren't
suitable candidates for traditional LASIK due to having corneas
that are too thin, can now benefit from the operation.
Furthermore, by using IntraLase LASIK there is a much reduced
risk of the corneal flap being displaced - a complication which
can arise with the microkeratome operation. IntraLase creates a
distinct beveled edge to the flap, enabling precise
repositioning and alignment after the procedure. This results in
optimal healing of the cornea following the operation.
The IntraLase operation is also quicker than traditional LASIK -
depending on the laser used, typically 30 seconds per eye as
opposed to around one minute. This has the benefit of greater
comfort and less worry for the patient.
With regard to outcome of the procedure, results of clinical
studies indicate that IntraLase patients have better resultant
vision than those who underwent the traditional LASIK procedure
employing a manual blade technique. The following are some of
the benefits:
* More patients achieved 20/20 or better vision * Reduced
frequency of post-operative night-time glare and halos * Reduced
incidence of dry eye symptoms * Fewer enhancement procedures
needed following the initial operation * Reduced frequency of
induced astigmatism after the operation * Patient satisfaction
much higher in those expressing a preference
The cost of an IntraLase operation is higher than that of
traditional LASIK eye surgery. About a 20% increase has been
quoted. However the added degree of safety combined with the
promise of better vision is persuading increasingly more laser
eye surgery patients to opt for IntraLase.
