Small Pupil Clinical Trial
Official title:
Evaluation of an Iris Dilatation Ring in Cataract Surgery
During cataract surgery, it is necessary to dilate the iris in order to remove the
crystalline lens and position the implant. The diameter of the optical implant being 6 mm, in
case of capsulorhexis crystalline access 5.5 mm, the expansion should be at least 6 mm.
At pre-operative consultation, the iris is always dilated by instillation of eye drops and
measured at the slitlamp. For patients with an inadequate dilation, the intervention requires
the use of a mechanical dilatation device.
This study aims to assess the value of an alternative dilatation ring to Malyugin ring, which
can be inserted and removed through an incision of less than 2 mm in diameter, due to its
size smaller than that of the Malyugin ring.
Our hypothesis is that this Bhattacharjee ring ensures sufficient and stable iris dilation
during surgery, enabling implant placement in good conditions.
