Cataract operation with small pupil and posterior synechia without manipulation on the iris
Roth E. H., Ludwig H.
Institut für Physiologische Optik, Düsseldorf
Objective: The film shows a cataract procedure with small pupil
without manipulation on the iris. In contrary to well known approaches
where the pupil margins are forced by retractores this procedure tries
to live without manipulation of the iris.
Method: A rhexis is performed of the pupil size and after hydrodelimination
the phako as well as the A/I is done through this small entry. Under a
little force the 5,5 mm diameter IOL is introduced in the capsular bag.
Wound closure is necessary when using this approach.
Results: An examination shows that the IOL sits in the bag. The
visual acuity raised from 0.2 to 0.7 as there were preexisting problems
caused by the iritis at the vitreous and the retina. The essential steps
of the whole procedure are shown in in the film.
Conclusion: The shown procedure is an alternative to stretching
the iris for proper view into the region of interest during the cataract
operation. The disadvantage of this method is the reduced visual overview
over the whole area of operation. The advantage is the minimum of trauma
that is done to the tissue.
