Title: Method for restoring vision in case of myopia
Inventor: GRUSHNIKOV IGOR A
IPC: A61H5/00
Filed: 1995-04-04
Granted: 1997-01-20
Abstract: FIELD: medicine; particularly, ophthalmology. SUBSTANCE: to restore vision affected with myopia, use is made of test object which is stepwise removed from patient's eyes. As test object is placed at remoter distance where patient sees test object elements worse, patient, by straining eye muscles, strives to achieve improvement in visibility of test object elements. Prior to proceeding to vision restoration process, patient's astigmatism limit is determined. Astigmatism limit is determined as follows: when test object is placed before this limit, patient perceives test object elements with good sharpness and contrast, but when test object is placed beyond astigmatism limit, patient sees same elements well, but without contrast. Changes in sharpness of vision of these elements as test object passes through this boundary, take place stepwise. Thereafter, object is removed to distance more remote from astigmatism limit and in this position patient, by straining eye muscles, seeks to achieve sharp and good-contrast visual perception of test object elements. This operation of successively removing test object away from patient's eyes is repeated until patient becomes able to see test object elements sharply and in good contrast at distance of at least 5. EFFECT: complete restoration of vision affected with myopia by eliminating astigmatism. 2 dwg
