[Evaluation of the anterior chamber depth after cataract surgery with OCT Visante].
BACKGROUND
OCT Visante allows the visualisation of the anterior segment structures and particularly of the irido-corneal angle by a non-contact method. We made a prospective study on 14 patients to demonstrate by OCT Visante the changes of irido-corneal angle and depth of the anterior chamber after cataract surgery.


METHODS
14 eyes of 14 patients have undergone a phacoemulsification of the cataract with posterior chamber lens implantation. All patients have had a complete ophthalmologic examination, an OCT Visante with angle measurement and an A-Scan for determination of the lens thickness. All these exams were repeated at 1 week and 1 month postoperatively.


RESULTS
In all patients, we noticed an increase of the postoperative iridocorneal angle. The mean preoperative angle was 18.3 degrees +/- 11.81 SD, 38.65 degrees +/- 3.95 SD at 1 week postoperatively and 45.7 degrees +/- 8.72 SD at 1 month.


CONCLUSIONS
Imagery by OCT Visante allowed us by a non-invasive method to quantify very precisely the opening of the irido-corneal angle and the increase of the anterior chamber depth after cataract surgery. OCT Visante is a method allowing the visualisation and quantification of anterior segment changes after cataract surgery.
