LASIK
Refractive errors are an aberration of the
optic of the eye wherein light from the object of regard is not
clearly focused on the retina. This disability is commonalty
corrected by the use of spectacles and contact lenses. Thus the
patient is dependent on these aids, for clear vision.
Refractive surgery permanently alters the counter of the cornea
( the most important focusing apparatus of the eye ) allowing
good vision without the use of spectacles or contact lenses
Wave front guided lasik : is the latest
technology for refractive procedure, which Dhami Eye Care
Hospital. Our post-operative results as presented at Annual
Conference of ASCRS were as good as proved in FDA trails in USA.
LASEK
(LASER SUBEPITHELIAL KERATOMILEUSIS)
Lasek Procedure mimics the Lasic procedure
except that the corneal flap that is lifted is only 50-60
microns in thickness as opposed to 160 micron thick flap in
lasic. This gives extra 100 micron thickness to the corneal bed
for excimer laser to work on.

Lasek procedure is used for eyes having relatively higher
refractive error or in eyes with thin corneas in whom Lasic
can not give good results.
A Thorough evaluation of your refractive
error and your cornea is essential before surgery is planned. If
your cornea is adequately thick as compared to your refractive
error you could safely go ahead with LASIK. But if you have a
relatively thinner cornea, LASEK could well be the procedure for
your eye.
Aberrometer: is used to
determine the total effective refractive error of the eye .the
procedure then corrects the total refractive error and not just
the error of the corneal curvature.it is very accurate and may
even achieve "super vision" in selective cases.
Topography : To evaluate the
corneal surface,shape and power
Pachymetry : To measure the
corneal thickness |
