Methods Forty eight patients (90 eyes) including 32 cases (60 eyes) of high anisometropia group and 16 cases (30 eyes) of severe anisometropia underwent SBK and were followed up for six months. The uncorrected visual acuity (UCVA), the best corrected visual acuity (BCVA), near stereopsis were measured and compared before and after SBK. Results The degree of pre-operative anisometropia was (4.75 ±2.83) D and that of post-operation was (0.35 ±0.15)D. The UCVA were reached 1.0 or better in 84 naked eyes in six months after SBK, while more than 78 eyes wore glasses pre-operatively. Among 48 patients wearing glasses previously, there were 15 cases of normal stereopsis, 15 cases of abnormal stereopsis and 18 cases of stereo blindness. In six months after SBK, there were 28 cases of normal stereopsis, 14 cases of abnormal stereopsis and 6 cases of stereo blindness. The near stere
