Ultrasound biomicroscopy of silicone posterior chamber phakic intraocular lens for myopia.
OBJECTIVE
To study the intraocular position and anatomic relationships of PRL-III (phakic refractive lens) (PRL) posterior chamber phakic intraocular lens (PCP IOL) for high myopia using ultrasound biomicroscopy (UBM).


METHODS
Centro Oftalmológico Real Vision, and Instituto de Investigaciones Oftalmológicas Ramón Castroviejo, Universidad Complutense de Madrid, Madrid, Spain.


METHODS
Sixteen phakic myopic eyes that had had PRL implantation were examined by UBM 1 month after surgery. The PRL position, PRL-crystalline lens peripheral distance, and central distance between the corneal endothelium and the PRL were measured.


RESULTS
Both haptics were on the zonule in 6 eyes, in the ciliary sulcus in 5 eyes, and impacted in the ciliary body in 1 eye. In the 4 remaining eyes, the haptics were in mixed positions. The mean PCP IOL crystalline lens peripheral distance in the minor axis was 588.1 microm +/- 232.5 (SD), and the mean PCP IOL-endothelium central distance was 2082.8 +/- 277.6 microm.


CONCLUSIONS
Phakic refractive lens implantation should be done carefully because of the sulcus location of the haptics in many cases. This, with the iris-PRL contact, suggests caution for the long-term outcome.
