WHAT IS LASER INTERFEROMETERY ?
Laser interferometer is an equipment meant clinically to determine outcome of a cataract surgery especially where cataract is mature or hyper mature.
In this type of cataract, retinal details cannot be seen hence in spite of best surgery, outcome may not be rewarding due to associated macular pathology.
Laser interferometry done prior to surgery, tells us how much vision should be expected.
It is based on the principle of interference. Patient sees stripes whose size can be varied as desired.
Depending upon size of stripe appreciated patient’s vision can be assessed.
However this test is more of academic importance and has not been able to gain any clinical significance because of its limitations.
