Purpose:
To evaluate the rotational stability of an angle supported anterior chamber phakic lens (Alcon Acrysof Cachet).
Setting:
: Zentrum für Refraktive Chirurgie, Augenabteilung am St Franziskus Hospital, Münster, Germany
Methods:
Observational study of 54 consecutive myopic or myopic astigmatic eyes of 30 patients. Phakic IOLs were implanted by the same surgeon in general anesthesia. Patients were kept in supine position for 2 hours after surgery. Then a slit-lamp exam was performed and the rotational orientation of the IOL was noted by rotating a narrow beam perpendicular to the IOL until congruency with the longer diameter of the IOL was achieved. Additional follow-up exams were scheduled 1 day, 4 days, 1 month, 3 months, and 6 months after surgery. Maximum difference of orientational angles between 2 consecutive follow-up visits and between baseline and last visit were evaluated.
Results:
Implantation was uneventful in all eyes with unremarkable slit-lamp findings and normal intraocular pressure at the first and all following exams.
Rotation between first and last follow-up visit was >3° in 65%, >5° in 56%, >10° in 41%, and >20° in 17%, respectively. Maximum rotation between any 2 consecutive follow-up visits was >3° in 70%, >5° in 56%, >10° in 37%, and >20° in 19%, respectively. Maximum rotation between any 2 follow-up visits was >3° in 74%, >5° in 61%, >10° in 44%, and >20° in 19%, respectively.
Conclusions:
In the absence of adverse effects marked rotational movements were noted within the first 6 months postoperatively. Thus, this angle supported anterior chamber phakic lens may not be a good platform for a toric model.
