Abstract Details

Purpose:

To improve the technique for IOL repositioning and for reliable IOL intrascleral fixation without the use of viscoelastics. 1. To develop a technique for IOL repositioning and IOL fixation in various complicated clinical situations. 2. To assess the results of the developed surgical intervention.

Setting:

Eye clinic : " Spectr" 125252, Proezd Berezovoi Roschi 12, Мoscow, Russia

Methods:

67patients(72eyes),age 52-89 y.o,with dislocation of  PCIOL were observed for 10 years.IOL dislocation with PCrupture-29 eyes;in-the-bag IOL dislocation-43 eyes.Patients underwent surgery according to micro-invasive technique developed by us without use of viscoelatic.5 eyes had combined pathology of posterior segment disease .Following types of IOLs were repositioned:Alcon Acrysof IQ Natural,Acrysof 3-part, Rayner aspheric,Akreos AO,Hanita lenses.For fixation of IOL after its reposition we used the sclerocorneal-pars plana method, developed by us,which gives reliable fixation of almost any type of most frequently used IOL.VA before surgery:0.01-0.7cc (on average,0.28 ± 0.06).IOP:14-25 mmHg.

Results:

In 69 cases  IOL central stable fixation was achieved.In 3 cases IOL decentration of 1 mm was observed,which didn't affect the result of operation.IOL-Re-fixation was not required.Visual functions in patients corresponded to initial situation before IOL dislocation and degree of preservation of optic nerve and retinal layers. VA: 0.2 to 1.0 cc (on average 0.78 ± 0.08). IOP after surgery:11-23 mm Hg. in 68 cases. In 4 cases transient ocular hypertension was observed up to 26 and 37 mm Hg, treated with drops for 1.5 months.Since no scleral/conjunctival incisions were made no stitches were neededed to be removed p/o later.

Conclusions:

1.The proposed method of transscleral fixation of the IOL into the iridociliary sulcus is low-traumatic and highly effective, which is confirmed by postoperative  results. 2.In addition, it allows to preserve the pupillary function and avoid significant post-operative complications.
