A NEWLY MODIFIED AND IMPROVED LASER APPARATUS (MODEL II) TO DETERMINE POSTMORTEM CORNEAL TURBIDITY IS REPORTED.
Abstract
THE WORKING PRINCIPLE OF THE LASER APPARATUS MODEL II IS THAT THE INTENSITY OF A LASER BEAM, PASSING THROUGH AN EXCISED CORNEA IS CONVERTED INTO ELECTRICAL PULSES BY A PHOTO-CELL, AND THE PULSES ARE AMPLIFED AND REGISTERED TO A VOLTMETER. THE DEGREE OF THE CORNEAL TURBIDITY IS, THEREFORE, EXPRESSED IN AN OBJECTIVE READING OF THE VOLTMETER. BY USING A LASER, AN ATTENUATOR, A COLLIMATER, A SPECIAL FILTER AND A CONTROL ARRANGEMENT IN THE LASAR APPARATUS MODEL II, THE ACCURACY AND EASE IN DETERMINING CORNEAL TURBIDITY AND IN MAINTAINING THE APPARATUS ARE MUCH IMPROVED BY COMPARISON WITH THE EARLIER MODEL. SUMMARY IN JAPANESE.
