Abstract Details
Purpose:
Clinical evaluation of the effectiveness and safety of the method of Acrysof IQ Toric lens in the bag reposition and suture fixation after the dislocation in the posterior chamber of the eye.
Setting:
S.N. Fyodorov Eye Microsurgery Institution, Moscow, Russia
Methods:
Prospective, observational, non-comparative case that included 4 eyes of 4 patients that underwent cataract surgery with implantation Alcon AcrySof IQ Toric lens 5-8 years earlier. The mean astigmatism before repositioning was 3.25 ± 0.5 D. A day before repositioning a strong axis on the cornea was marked, after that 4 YAG laser coloboms in the iris were performed, two coloboms on each side in accordance with projected markings on the iris. On the next day, the IOL was centered and sutured to the iris based on earlier made coloboms using the 9,0 polypropylene suture.
Results:
During a control examination one year later, the sutures were consistent, the lens was centered and corresponded to the predicted axis within 5 ± 3 °. The UCVA was 0.3 ± 0.5D. VSVA = 0.6 ± 1.0D. The appearance of myopia 1.0 ± 0.5 D was detected. The iris excursion is preserved. In one case pupil ovulation was observed. In one case there was an increase of IOP after the operation, Po = 29mmHg further antiglaucoma operation was required.
Conclusions:
Combined laser method of preparation and suture fixation IOL-Capsular Bag Complex to the iris allows to save the lens, restore the quality of vision. The performed perforations of the iris help to make the suture fixation easier, allow the lens to be correctly positioned in accordance with predicted axis, exclude its rotation and preserve the pupil's excursion. Fixation of IOL to the iris leads to myopic refraction within 1.25 D. Surgical method does not cause induced astigmatism.
