Abstract Details

Purpose:

To compare the visual outcome, complication and result of conventional versus modified trans scleral fixation of IOL in combined vitreoretinal surgery.

Setting:

A prospective comparative analysis of two surgical methods carried out at 3rd eye clinic, Ahmedabad.

Methods:

50 patients were included in the study with indication of post operative dropped nucleus, traumatic dislocated or subluxated lens and dislocated IOL. Patients with co existing vitreoretinal diseases were excluded. All the patients were divided in to two equal groups randomly. All the patients had undergone complete pars plana vitrectomy along with lensectomy or removal of intraocular lens. All the patients in first group had undergone conventional scleral fixation of IOL. Patients in other group had undergone modified transcleral fixation of IOL without usage of fibrin glue. The results were assessed with visual outcome, anatomical success and complications. Visual acuity, post operative refraction, IOP, IOL position, fundus examination, UBM were done in pre and post operative period.

Results:

There was no stastical difference in final post operative visual acuity and post operative astigmatism in both the groups. Intraocular inflammation was found less with modified technique. Incidence of vitrectomy related complications were equal in both the groups. IOL decentration and heptic related problems were noted more in modified technique.

Conclusions:

Modified trans scleral fixation of intraocular lens during combined vitreo retina surgery is safe and effective technique and less time consuming compared to conventional scleral fixation. The visual outcome and complication rate is comparable in both the approach. IOL decentration and heptic related problems are main concerns in modified method.
