An instrument has been designed to study the pulsatile motion of the eye by analysis of a beam of light reflected from the corneal surface. A laser light beam probe of small spot size and low divergence strikes the cornea apex and the reflected movement is recorded by a sensor. Analysis of the beam movement reveals the energy in the eye pulse without the necessity of physically touching the eye. The value of the intraocular pressure is determined from the calculated power spectrum. The sensitivity, accuracy and efficiency of the light beam makes possible studying both eyes concurrently and comparison of the pulse parameters of onset, amplitude and duration reveals any delay in circulation to an eye.

Reflective non-contact ocular pulse analyzer for clinical diagnosis of eye and cerebrovascular disease

This invention provides apparatus and method for preventing eye damage, particularly to the retina, resulting from direct exposure of the eye to intense light from a light source during eye surgery. A shield having a diameter less than that of the cornea is placed directly on the cornea, between the light source and the retina. By so doing, this shield prevents damage to the eye, and especially to the retina, to thereby enhance probability and speed of full recovery after eye surgery.
