| Summary: |
In recent years, owing to
better postoperative effects, phacoemulsification has
become a leading technique of cataract surgery. Its
application, however, may pose some problems in treating
white cataract mainly due to insufficient
retroillumination. It is particularly relevant during
capsulorhexis, critical in subsequent stages of the
process, during which visualization may be improved with
the dyes application. Many dyes exist that can be used
during cataract surgery which enable the implementation
of phacoemulsification in the cases earlier reserved for
extracapsular cataract extraction. Apart from the
benefits, their application may have some side effects.
The following article has the aim to present dyes used
in cataract surgery, their potential toxicity and other
possible undesirable effects, as well as application
methods. The use of dyes provides the surgeon an equally
effective alternative, i.e. phacoemulsification, instead
of extracapsular cataract extraction in the cases of
insufficient visualization. With mature cataract,
however, phacoemulsification may result in various
complications, since those associated with insufficient
retroillumination have been greatly reduced due to the
application of dyes. |
