METHOD FOR CALCULATING KERATOTOMY IN CASES OF LOW AND MODERATE DEGREE MYOPIA

摘要

FIELD: medicine. SUBSTANCE: method involves measuring subjective refraction using optopatterns at 5 m distance (Rc) and accommodation in relative rest state on laser glass under artificial illumination at 1 m distance (Rl). The condition of Ra=Rc being satisfied, accommodation apparatus is considered to be in normal state, the received subjective refraction value is used for calculating keratotomy. Rc Rl being satisfied, accommodation tonus is considered to be below norm and Rc is used for calculating operation parameters. Rc Rl being the case, accommodation spasm is observed and operation is to be postponed until accommodation apparatus comes to normal state. EFFECT: high accuracy in calculating operation parameters; excluded undesirable side effects of accommodation stress. 6 dwg
