SURGERY REFRACTIVA IN MIOPIA AND ASTIGMATISM
Myopia, hipermetrophy and
astigmatism they are ocular faults or also called mistakes refractive
due to an alteration in the projection of the images on the plane
of the retina. These images will have to be focused in the retina,
and nevertheless they are not it, nice for increase or decrease
of the size of the eye or for an excess or fault of the curvature
of the cornea. The persons with these faults generally have the
healthy eyes, but a problem exists: the vision is blurry and distorted,
needing alteration by means of glasses or contact lenses.
Nowadays and for some time an alternative
exists to the glasses and to contact lenses that it is of type
surgical (radial(road) Queratotomia, extraction of crystalline
transparent with implant intraocular, queratectomia photo refractive,
implantation of lenses intraocular of previous chamber or posterior
chamber PRL or ICL, etc.), but in our opinion and experience,
the surgical option more indicated at present for its case is
" Queratomia in situ attended by laser Excimer " or
also named "Lasik", and this prestificada for different
(labour) aesthetic motives, intolerance to contact lenses, bad
vision with glasses, sport, bad quality of life when glasses or
contact lens depends in everything of, etc.
It is important to emphasize that
with this treatment there are not modified the previous conditions
of the myopic eye or astigmate (possible degeneracy of the retina
and risk of own alone detaching of the very high near-sighted
persons, increases of the myopia for development, pregnancy, etc.)
there are not even modified the previous conditions of the eye
hipermetrope-astigmate (since predisposition though exceptionally
not frequently, to the Glaucoma), that can follow its natural
course in spite of the intervention
How it occurs with Lasik/Lasek?
To correct the myopia, the hipermetrophy
and the astigmatism with this technology(skill), it is necessary
to modify the corneous curvature of the previous face. This is
obtained carving by means of the laser Excimer a minimal quantity
of fabric in the central part of the cornea. Our medical equipment(team)
fulfils this remodelled one of the cornea by means of the laser
Excimer MED-70. This photocoagulation of the fabric, it is not
realized on the surface of the cornea, but to more of 150 microns
of depth, for which is necessary to prepare a thin corneous sheet
that will cover in the postoperatory one the zone treated by the
laser.
This procedure - system
LASIK - has three advantages:
1. Absence of pain in the postoperatory
one.
2. Visual rapid recovery.
3. Need of retreatment stops to fit very low. The final lens is
to reach, its optical alteration, a visual useful keenness of
90-95 % reducing y/o eliminating the dependence of glasses or
contact lenses for the immense majority of daily and like that
activities to improve the quality of life.
Which are the results that will be obtained?
In our experience the wished result
(neither useful vision nor optical some alteration) is obtained
in almost all the cases (> 90 %), nevertheless in 5 % a weeks
they must be portrayed. The visual recovery is rapid with a stable
vision in the time in the majority of the cases. Every day thousands
of interventions are realized, if You. It chooses to produce(operate
on), his(its) decision must be based well. The patient more satisfied
is that one that has a suitable information. |
