Experimental errors in digital image processing for the determination of geometrical parameters of the human eye.
A new method is presented for measuring geometrical parameters of the anterior segment of human eye. A digital imaging technique is employed in conjunction with a slit lamp and TV camera. A method was developed to analyze images and the problem of minimizing measuring errors was studied. The method was tested using a contact lens to simulate the anterior corneal surface.
