Abstract Details

Purpose:

To investigate the outcome of cataract surgery in patients with legal blindness defined as best-corrected visual acuity (BCVA) of 20/1000 or lower and to determine factors influencing the visual outcome in these patients.

Setting:

Kangwon National University Hospital

Methods:

Medical records of 68 eyes of 62 patients diagnosed with legal blindness and underwent cataract surgery were reviewed. The study population was divided into 3 groups based on types of cataract (Group A : posterior subcapsular cataract, Group B : mature or brunescent cataract, and Group C : cataract combined with other ocular diseases). Data including demographics, predisposing factors, BCVA before and 6 months after surgery and post-operative complications were collected and analyzed.

Results:

Preoperative logMAR BCVA was 1.88�Â�±0.24, 2.24�Â�±0.26 and 1.96�Â�±0.31 in Groups A, B and C, respectively (P=0.003). Postoperative BCVA was 0.49�Â�±0.35, 0.51�Â�±0.47and 0.90�Â�±0.53 in Groups A, B and C, respectively (p=0.003). Significant visual improvement was shown in all 3 groups (P<0.001 in Groups A and B and, P = 0.001 in Group C). There was significant difference in visual improvement among the 3 groups P<0.001). Although there was no significant difference in visual improvement between groups A and C (P=0.379), significantly higher visual improvement was achieved in group B compared to other groups.

Conclusions:

Cataract surgery can be recommended even for patients with legal blindness.
