Abstract Details

Purpose:

To analyze the long-term results of the IOL iris fixation in the opposite direction taking into account the position of the lens, intraocular aberrations and the state of the pupillary function

Setting:

S. Fyodorov Eye Microsurgery Federal State Institution, Irkutsk, Russia

Methods:

: 37 patients (age 67-85 years) with iris fixated IOL (AcrySof IQ SN60WF) were examined 3-5 years after the surgery. At the time of the operation, all patients had a significant weakness in the ligamentous apparatus of the lens. During the operation IOL was fixed to the peripheral part of the iris with two needles thread. The suturing was done in the direction “capsule-iris-cornea” by creating a loop suture around the lens haptic element (one surgeon, one surgical approach). Visometry, OCT images, ultrasound biometry (HiScan), aberrometry, ultrasound biometry (HiScan), pupillometry (OPD-scan II, Pentacam HR) were performed.

Results:

Visual acuity was 0.4-1.0 (decimal scale) and varied depending on the condition of the retina and the optic nerve. Macular edema was not detected in any case. The IOL was stable both in vertical and in supine position. RMS total was 0.90±0,33 µm, the pupil diameter under photopic conditions was 3.24±0.27 mm, in mesopic conditions – 4.97±0.38 мм, in target approximation – 2.60±0,52 mm.

Conclusions:

The presented of the IOL iris fixation by the method of opposite direction ensures a stable position of the IOL in a long-term period. Fixation of the IOL haptic element to the peripheral part of the iris did not affect the pupillary diaphragm functional state and did not have a significant contribution to intraocular aberrations.
