| Summary: |
Purpose: to
evaluate the effects of cataract extraction and lens
implantation on corneal endothelium morphology.
Material and methods: In 21 eyes of 14 children
with congenital or developmental cataract, corneal
endothelium was studied. Patient age was 9 to 19 years (mean
12.9 years). In all eyes extracapsular cataract
extraction (ECCE) with PMMA intraocular lens
implantation was performed, without primary posterior
capsulotomy or anterior vitrectomy. Lens wearers,
patients with traumatic cataract or external eye
diseases and ocular surgery in history were excluded.
The endothelium was imaged by non-contact microscope
Topcon SP-2000P. This examination was done
preoperatively and 1 month, 6 months and 1 year
postoperatively. Corneal thickness (T), corneal
endotheliel density (ECD) and mean cell area (AVG) of
endothelial cells were examined.
Results: Mean corneal thickness was 0.55 mm after
1 month, 0.54 mm after 6 months and 0.54 mm after 12
months. The mean preoperative endothelial cell density
was 3231.1 cells/mm2. ECD after 1.6 and 12 months was
2874.3; 2639.2 and 2479.9 cells/mm2 respectively. Mean
endothelial cell loss was 10.94% after 1 month, 17.85%
after 6 months and 22.68% after 12 months. AVG before
operation was 315.8 mm2, after 1 month 355.8 mm2, after
6 months 382.4 mm2 and 399.5 mm2 after 12 months.
Conclusions: Changes in corneal endothelium
morphology had no effect on transparency of the cornea. |
