Abstract Details

Purpose:

To evaluate changes on the anterior segment parameters after myopia surgery with two different phakic iols.

Setting:

Hospital de Braga, Braga, Portugal

Methods:

Forty eyes were included in this study. Twenty eyes were operated with an iris-claw phakic iol (Artiflex, Ophtec BV) and 20 eyes were operated with a posterior chamber phakic iol (ICL V4c, STAAR Surgical). Patients were evaluated preoperatively and six months after surgery with Pentacam. The parameters evaluated were: anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA), pupil diameter (PD) and intraocular pressure (IOP).

Results:

In the Artiflex group the ACD changed from 3.23mm to 3.07mm (p=0.001), the ACV changed from 206mm3 to 181mm3 (p=0.001) and the ACA from 37.9�â��° to 42.1�â��° (p=0.01). The mean PD was 2.82mm in the pre-op and 2.83mm at 6 months (p>0.05). In ICL group the ACD decreased from 2.99mm to 2.89mm (p=0.01), the ACV from 178mm3 to 125mm3 (p=0.0001), the ACA from 36.6�â��° to 26.5�â��° (p=0.0001). The mean PD decreased from 3.83mm to 3.39mm (p=0.01). There were no statistically significant differences in the IOP in both groups.

Conclusions:

Myopia surgery with phakic iols significantly changes the anterior segment parameters. Those changes are not associated with changes in the IOP.
