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
