Tests Involved


Schirmer’s test is a measure of the tear secreting capacity of the eye. Deficiency in tear secretion can lead to a chronic condition called dry eye. The test involves the placement of a special filter paper strip across the lower eyelid margin and measuring the length of the strip that is wetted by the tears over a one-minute period.

Keratometry involves the measurement of the corneal curvature in two meridians. The cornea is the front portion of the eye that is clear like a watch glass. The curvature of the cornea helps it to focus on the light parts. Measurement of the corneal curvature is needed for fitting the proper contact lens. It is also needed for the calculation of the IOL power before cataract surgery.


Corneal topography is the detailed mapping of the surface of the cornea. Advanced computer analysis of several spots on the surface of the cornea using the study of the reflected image is done. Color-coded graphs of the surface map enable the doctor to diagnose certain conditions such as keratoconus. Before undergoing excimer laser treatment for getting rid of glasses, one needs to perform this test to understand the surface of the cornea better and plan the treatment accordingly.

Pachymetry is the study of the thickness of the cornea. The accurate measurement of the thickness is made possible by using ultrasound or optical means. Measurement of the thickness is important in the diagnosis and management of certain corneal conditions such as keratoconus, corneal endothelial dystrophy, etc.


Specular microscopy is a test that enables the evaluation of the back-most layer of the cornea called the endothelium. The health of this layer is important in maintaining the clarity of the cornea. With age, injury, surgery, and in some diseases this layer may have a reduced number of cells and become abnormal. The study of this layer is done by counting the number of cells per square millimeter as well as study the type of cells. This study is important in planning certain surgeries.
