Frequency Analysis Of Radial Tear During Cataract Surgery With Anterior Capsular Fibrosis

To analyze the frequency of radial tear during cataract surgery with anterior capsular fibrosis

retrospective

From Dec 2016 to Dec 2021, medical records were retrospectively reviewed for cataract patients with anterior capsular fibrosis (ACF) who underwent phacoemulsification with intraocular lens implantation. The frequency of radial tear according to the location of ACF was analyzed by dividing the anterior capsular area into 4 quadrants. The relationship between whether the ACF is located at the margin of continuous curvilinear capsulorrhexis (CCC) or not and the frequency of radial tear was analyzed by Fisher's exact test.

In 9 out of total 24 patients (35.7%), radial tear occurred, and in 5 of them, posterior capsular rupture occurred and vitrectomy was performed. When the location of ACF was divided into quadrants, 2 out of 2 cases (100%) at quadrant I, 1 out of 1 case (100%) at quadrant II, 4 out of 7 cases (57.1%) at quadrant III, and 1 out of 7 cases (14.3%) at quadrant IV were recorded respectively. When the ACF is in the quadrant IV, the incidence of radial tear tended to be low. The incidence of radial tear when the ACF is located at the margin of CCC was 47.1% (p=0.191, Odds ratio=5.333).

The frequency of radial tear tends to be higher when the ACF is located at the margin of CCC and at quadrant I or II, so it should be noted during cataract surgery.
