The Lens Opacity Meter 701 (Interzeag, Switzerland) is a recently developed instrument for assessing cataract. It measures the degree of scatter of a red light beam by the lens. Fifty patients prior to cataract surgery had measurements made before and after dilatation of the pupil. Inconsistent results were found at pupil diameters of less than 4 mm. It is postulated that this was due to absorption of scattered light by the iris.
晶状体混浊度仪701型（瑞士Interzeag公司）是最近研发的一种用于评估白内障的仪器。它通过测量晶状体对一束红光的散射程度来进行评估。50例白内障手术患者在瞳孔散大前后均进行了测量。结果发现，在瞳孔直径小于4毫米时，测量结果不一致。据推测，这是由于虹膜对散射光的吸收所致。
