Predicting acuities in capsulotomy patients: interferometers and potential acuity meter. 1983

W Faulkner

Using the Lotmar moiré fringe interferometer and the potential acuity meter, I predicted the postoperative Snellen visual acuities in 30 implanted eyes that required secondary capsulotomies. The Lotmar interferometer was within one line of the postoperative visual acuity in 29 eyes (96.6%); the potential acuity meter prediction was within one line in 10 eyes (33.3%). An earlier study defined seven clinical conditions that produced false positive results with the laser interferometer. The same results occurred with the Lotmar interferometer. When the potential acuity meter was used, six of the seven conditions produced false positive results.

D007368	Interferometry	Measurement of distances or movements by means of the phenomena caused by the interference of two rays of light (optical interferometry) or of sound (acoustic interferometry).	Interferometries
D007903	Lens Capsule, Crystalline	The thin noncellular outer covering of the CRYSTALLINE LENS composed mainly of COLLAGEN TYPE IV and GLYCOSAMINOGLYCANS. It is secreted by the embryonic anterior and posterior epithelium. The embryonic posterior epithelium later disappears.

D007908	Lens, Crystalline	A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION.	Eye Lens,Lens, Eye,Crystalline Lens

D014792	Visual Acuity	Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.	Acuities, Visual,Acuity, Visual,Visual Acuities
