Abstract Details

Purpose:

To report an ab-externo direct suturation technique for the scleral fixation of a subluxated intraocular lens (IOL).

Setting:

Dokuz Eylul University School of Medicine, Izmir, Turkey.

Methods:

A 62-year-old diabetic woman presented with visual deterioration in her right eye. On ophthalmologic examination, best-corrected visual acuity (BCVA) was 20/400 in the right eye and no light perception in the fellow eye. Inferiorly subluxation of the IOL along with its capsular bag like a setting sun was detected in the affected eye on slit-lamp biomicroscopy; however a mature cataract with iridophacodonesis, rubeosis iridis and absolute glaucoma were present in the fellow eye. A surgical intervention was scheduled to fix the subluxated IOL to the scleral wall.

Results:

Conjonctival peritomies and scleral flaps were created at superior nasal and temporal quadrants. Clear corneal incisions were performed at inferior nasal and temporal quadrants. A double-armed 10/0 polypropylene suture on straight needles was consecutively inserted into anterior chamber from inferior temporal quadrant, passed inside the optic of IOL, and fixed it to the scleral wall by knotting the two arms under the scleral flap. Procedure was repeated from inferior nasal quadrant and IOL was refixed to the scleral wall at superior temporal quadrant. At the postoperative third month, BCVA was 20/50, and IOL with its capsular bag remained well-centralized.

Conclusions:

The presented technique provides a simple, effective and safe approach for repositioning and scleral fixating of a dislocated IOL with its intact capsular bag. Reduced surgical time and lack of disruption in the anterior chamber stability are the major advantages of such procedure.
