The "Allegretto Wave front Technology"
Excimer laser corrects refractive errors within
seconds by modifying the corneal curvature
A refractive error results when incoming rays
of light are not brought to a precise focus
on the light sensitive retina lining at the
back of the eye. Myopia (Short-sight), hyperopia
(Long-sight), and astigmatism (cylindrical
error) can result in poor vision. Spectacles
and contact lenses are conventionally used
to correct refractive errors. Incisional techniques,
like Radial Keratometry have been attempted
in the past to correct myopia. However, the
long-term hazards and complications of this
procedure have made it obsolete. The EXCIMER
LASER has emerged as a promising tool that
has vastly improved the accuracy and safety
of Refractive surgery. The EXCIMER LASER destroys
intermolecular bonds in corneal tissue, enabling
precise tissue removal. Altering the corneal
shape corrects refractive errors - the procedure
is termed photo refractive keratectomy (PRK).
A newer modification of the treatment is the
procedure called LASIK which has further enhanced
the efficiency of the procedure. The Indian
Oil Corporation Excimer Laser Centre at Sankara
Nethralaya acquired the first summit Excimer
laser in India, in November 1992. We are proud
to announce the acquisition of the state-of-art
Allegretto Wave Excimer Laser in December,
2001, in order to bring the best treatment
to the people of our country. This equipment
has several unique features, that ensure a
very high level of precision in the treatment
of refractive errors. The center has performed
in excess of 8000 refractive surgical procedures
with good results, comparable with results
achieved in other reputed Refractive Centers
anywhere in the World.
