| Summary: |
Objective:
Assessment of post operation astigmatism and dynamics of
its reduction within three month after the procedure.
Material and methodology: The research included
cataract removal in 140 eyes by means of
phacoemulsification (100) and extracapsular (40) methods.
Central keratotomy and refraction measurements were
conducted with a refractor on 2nd, 7th, 30th and 90th
day after the procedure.
Results: Average value of postoperative
astigmatism after an extracapsular cataract removal was
4.69 D on the second day. After a phacoemulsification
without a suture the value was 1.36 D, with a single
loop suture – 1.98 D, with a single criss-cross suture
it was 2.89 D. Two alternative parameters of astigmatism
reduction were suggested: a half-value period and a rate
of reduction.
Conclusions: Average early postoperative
astigmatism values after an extracapsular cataract
removal are at least twice as high as in the case of a
phacoemulsification cataract removal. A suture applied
after a phacoemulsification results in an increase in
early postoperative astigmatism. Astigmatism half-value
period and rate of reduction provide a good description
of the dynamics of postoperative astigmatism reduction. |
