Abstract Details

Purpose:

To evaluate changes and impact of angle kappa after Implantable Collamer Lens (ICL) implantation upon the Quality of Vision (QOV) questionnaire.

Setting:

Shenyang He Eye Hospital, Shenyang, Liaoning, China.

Methods:

V4c (Star, Switzerland) ICL implantation was carried out in 60 eyes of 30 consecutive patients and were retrospectively analysed. During preoperative and postoperative 3-month assessment, anterior chamber depth visual acuity, angle kappa (OPD-Scan (Nidek Inc) and QOV questionnaire were assessed.

Results:

The was a significant decrease in angle kappa value postoperatively (p<0.05). Postoperative angle kappa significantly correlated with glare and halo symptoms (R=0.306, P<0.001) and (R=0.412, P<0.001) respectively and night vision problems (R=0.370, P<0.001). The preoperative angle kappa corelated significantly with glare and halo symptoms (R=0. 251, P<0.001 and R=0. 293, P<0.001 and) and night vision problems (R=0.224, P<0.001). There was no significant correlation between pre or postoperative visual acuity and angle kappa.

Conclusions:

Values of angle kappa decreased significantly after ICL implantation at 3-months assessment. Angle kappa might may play a role in the occurrence of photic phenomena after ICL implantation, however the visual acuity of the patients did not correlate with pre or postoperative angle kappa. Preoperative angle kappa along with other ocular biometric parameters may be used to predict the postoperative QOV in high myopic patients undergoing ICL implantation.
