Abstract:
From October, 1984 to December, 1988, 1177 cases of posterior chamber lens were implanted. Clinical study was done on 1030 cases which could be followed up for more than 2 months. The results were as follows: 1. The best corrected visual acuity of 0.5 or better was in 981 cases(95.2%) and 1.0 or better was in 676 cases(65.6%). 2. the best corrected visual acuity was achieved with the correction of average -1.07 +/- 1.28D by spherical equivalent. 3. The postoperative astigmatism was average 1.57 +/- 1.70D. 4. The difference between the calculated prediction of postoperative refraction and the actual postoperative refraction was less than 1.00D in 64.1% and calculated prediction tended to be biased toward hypermetropia with mean error of 0.37 +/- 1.21D.
