Postoperative hyphema following cataract extraction surgery is not usually a serious complication and clears quickly in the most cases. Sutureless cataract surgery was reported to have less incidence of postoperative hyphema than conventional
cataract
surgery. We analyzed the incidence of postoperative hyphema in each group according to the depth and the length of scleral pocket incision in 500 eyes with the sutureless cataract surgery via superior incision during two years.
One day after surgery, 90 cases(18.0%) had hyphema and most of them (74.4%) showed Grade 1 severity. The incidence of hyphema was 23.0% in the deep incision group and only 11.9% in the superficial incision group (p<0.01). The percentage of grade
1
hyphema was 66.6% in the deep group and 92.6% in the superficial group, then severity was greatly reduced in the superficial incision group (p<0.01).
The incidence of hyphema in the group of 7.0mm in length was highest among the 6.0, 6.5, 7.0mm groups (p<0.01), and the shorter the incision length, the milder the severity of hyphema(p<0.01). The incidence of hyphema was the lowest(6.2%) in the
group
of 6.0mmin length and superficial incision, and it was the highest(28.5%) in the 7.0mm in length and deep incisional group (p<0.01).
