Abstract Details

Purpose:

To report improvement of corneal edema after cataract surgery in patients with mild to moderate bullous keratopathy (BK).

Setting:

Osaka University Hospital, Osaka, Japan

Methods:

A retrospective case series of patients with BK in whom corneal edema was improved after cataract surgery prior to DSAEK. Medical records of 5 patients (1 man and 4 women, age; 73 ± 10 years old [mean ±SD] ) with BK were reviewed with regard to preoperative and postoperative LogMAR best corrected visual acuity (BCVA), central corneal thickness (CCT), corneal edema (CE) and anterior chamber depth (ACD). CE was graded from 0 through 4, where 0 = no edema, totally transparent, 1 = mild edema, mild loss of transparency or focal edema without visual axis involvement, 2 = moderate edema, iris details seen, 3 = intense edema, some iris details seen, 4 = severe edema, no iris details seen. The time to recurrence of corneal edema was also examined in each ease.

Results:

Of 5 patients, 4 were BK secondary to argon laser iridotomy, and 1 was Chandler syndrome. The mean LogMAR BCVA was significantly improved from preoperative 1.09 ± 0.68 to postoperative 0.42 ± 0.35 (paired t-test; p=0.047). CCT became significantly thinner postoperatively than preoperatively (710±123µm vs 569±77µm; p=0.0093). The mean CE grade was significantly improved from preoperative 2.0 ± 1.0 to postoperative 1.0 ± 0.7 (p=0.034). The mean pre and postoperative ACD was 1.61 ± 0.56 mm and 3.22 ± 0.83 mm, and there was significant difference (p=0.016). One patient of partial BK has been retaining corneal transparency 6 years after cataract surgery. In the other 4 patients, central corneal clarity was maintained for 31 ± 28 months postoperatively.

Conclusions:

Corneal edema was improved after cataract surgery in 5 patients with mild to moderate BK. One factor might be postoperative changes in anterior chamber configuration. FINANCIAL INTEREST: NONE
