Laser With Online Pachymetry Introduced
EHM News Bureau - Mumbai
Imagine waking up and seeing clearly without having to reach
for your glasses or contact lenses. Laser vision correction (LASIK) with online
pachymetry is making this dream a reality for millions of people worldwide.
With refractive surgery for the treatment of Myopia, Hypermetropia and Astigmatism
gaining popularity, the ESIRIS Schwind Excimer Laser (Germany) with online pachymetry
is a breakthrough in correcting the refractive error of the eye with a greater
degree of accuracy.
The equipment has been installed at Doctor Eye Institute Pvt Ltd, Mumbai for
the first time in India. Says Dr Kumar Doctor, Medical Director, Doctor Eye
Institute, who has introduced this technology for the first time in India, "The
use of excimer laser is a quantum leap in the precision and safety of refractive
surgery over the previously dominant (manual) technique such as radial keratotomy
(RK) that involved the use of hand-held knife."
Excimer laser with LASIK surgery is performed under anesthetic eye drops. No
injection is necessary. "It is a painless, 10-20 minutes procedure. Both
eyes can be treated at the same time. Work can be resumed in 24 hours. We are
routinely using wave front and topo guided treatment for best visual outcome
and quality of vision at night," explains Dr Doctor.
The machine is also equipped with the latest orbscan II corneal topography system
used to map the cornea just as scientists map the Earth. This machine measures
the thickness of the cornea, which helps in determining how much cornea can
be fattened in order to achieve a satisfactory result without disturbing the
minimum required thickness. This helps in minimising tissue damage.
What is Pachymetry? Pachymetry (measurement of corneal thickness) is important
for determining whether adequate corneal tissue exists for performing the procedure.
This is particularly an issue in high myopia cases, where large amounts of corneal
corrections are required. A few years ago, there were no possibilities to measure
the corneal thickness during refractive corneal surgery or procedure. With this
new system, high-resolution micrometer measurements of corneal thickness can
be taken without the instrument actually touching the eye.
