| Summary: |
Purpose: The aim of
this study was to evaluate the influence of cataract
surgery on the condition of corneal endothelium, in
diabetic patients.
Material and methods: We examined 103 patients
(103 eyes) after cataract surgery (64 women and 39 men),
at the age between 49 and 89. In our study we didn't
involve any patients with intra or post-surgery
complications. Using Specular Microscope SP-1000 corneal
endothelium was examined before cataract surgery and in
the long-term follow-up: 7, 30 and 90 days after surgery.
The patients were divided into two groups: suffering
from diabetes (54) and matched control group –
non-diabetic patients with cataract (49). The same
patients were also divided depending on the type of
surgical technique: phacoemulsification (42) or
extracapsular cataract extraction (61).
Results: The mean percent loss of corneal
endothelium cells, due to surgery in diabetic patients
was: 11,31% after 7 days, 13,99% after 30 and 15,38%
after 90 days. In the control group: 5,45% after 7 days,
8,66% after 30 and 11,33% after 90 days. The mean
percent loss of corneal endothelium cells after
phacoemulsification was: 10,10% after 7 days, 13,21%
after 30 and 15,87% after 90 days; after extra-capsular
cataract extraction: 6,84% after 7 days, 9,71% after 30
and 11,48% after 90 days. Differences between mean value
of corneal endothelial cells in diabetic patients
compared with control group, were statistically
essential 7 and 30 days after cataract surgery, and near
such assessment 90 days after surgery. There were no
statistically essential differences between endothelial
cells density in both operated groups, in relation to
type of operation (phacoemulsification and
extra-capsular cataract extraction).
Conclusions: Above results are the evidence, that
cataract surgery is a big trauma for cornea, especially
for its endothellium. The operation is mainly dangerous
for patients suffering from diabetes. The surgeon should
be aware of the above threat during cataract surgery in
diabetic patients, and therefore should express high
level of caution, irrespective of the technique of
operation. |
