Postoperative visual acuity is rapidly recovered and higher than that of preoperative, as phacoemusification technique and 101 insertion technique is generalized and developed. But postopera-five low vision was not unusual. We analysed an peroperative characteristics, intraoperative problems, and postoperative complications in the group with postoperative visual acuity was decreased than preoperative or postoperative corrected visual acuity was less than 0.4
Phacoemusification with posterior chamber lens insertion were performed on 414 cataract eyes by one surgeon, from 1993 to 1995.
Eyes with postoperatvie visual acuity was decreased than peroperatively or less than 0.4 were designated Group A, 68 eyes(16.4%), and the remaining eyes were Group B, 346 eyes(83.6%), Preoperative characteristics in Group A were uveitis(16.2%), diabetic retinopathy(13.2%), Glaucoma(11.8%), macular abnormality(11.8%), etc.
Intraoperative complications, posterior capsule ruptures with vitreous loss occured in 21 eyes(5.1%). In 8 eyes(11.8%) of the 21 eyes were Group A, 13 eyes(3.8%) were Group B, and the difference between both groups were statistically significant (P<0.01).
Postoperative complications, in 12 eyes(2.9%) of 414 eyes were cystoid macular edema. In 11 eyes(16.2%) of 12 eyes were Group A, 1 eye(0.3%) was Group B, and both groups were statistically significant(P<0.01) and, 4 eyes were preceded by posterior capsule rupture. And recurred uveitis occured in 18 of the eyes(4.3%), and 12 eyes in group A, 6 eyes were Group B.
