Abstract Details

Purpose:

To analyse influence of cataract surgery on visual acuity (VA) in patients with aniridia.

Setting:

1. Clinical Department of Ophthalmology, School of Medicine with the Division of Dentistry in Zabrze, Medical University of Silesia in Katowice, Poland 2. Dept. of Ophthalmology, District Railway Hospital in Katowice, Poland 3. Hebei Provincial Eye Hospital Xingtai, China 4. Dept. of Ophthalmology with Pediatric Unit, St. Barbara Hospital, Trauma Center, Sosnowiec, Poland

Methods:

We analysed visual acuity in 28 patients with aniridia after cataract surgery, which has been performed from 2008 to 2016. The follow-up period was at least 6 months (mean 81,2 ± 45,3). Mean age of subjects was 34,5 ± 4,9 years. Baseline visual acuity ranged from light perception to 0,02 on Snellen charts. We analysed VA fluctuations caused byPK, limbal grafts, cultivated oral epithelium transplantations, which have had impact on it.

Results:

VA improvement over observation period was achieved in 71,4% eyes, worse vision was noted in 17,8%, no improvement was observed in 10,7 % eyes. Mean VA in successful cases increased to 0,15±0,08. On follow-up 6 PKs were performed, in 12 eyes oral mucosa cultivated epithelium was transplanted, 3 eyes underwent keratectomy with amniotic membrane application. 2 eyes became blind due to glaucoma, one cornea is cloudy, despite of two regrafts.

Conclusions:

Cataract removal in aniridia is chellenging surgery, which maintain satisfactory vision despite of corneal complications.
