Abstract Details

Purpose:

A Intraocular Lens (IOL) implantation in cases lacking of adequate capsular support, zonulolysis or IOL malposition, may require suture fixation to iris or sclera. There are different modifications of TSSF of IOL or devices for capsular bag fixation. We propose here our own technique for TSSF of intraocular implants, different from others by having less traumatic and shorter procedure that feasible to perform by burying the knot into peripheral corneal paracentesis. This technique do not required any conjunctival or scleral dissection and suturing.

Setting:

Corneal Unit, Department of Ophthalmology, Galilee Medical Center, Faculty of Medicine Bar-Ilan University, Israel

Methods:

A double 9-0 Polypropylene suture on a long needle fixated to an intraocular implant is passed by docking into 25G needle from the eye out through the sclera and the conjunctiva 2 mm posterior to the surgical limbus, then a suture needle is passed through a conjunctival exit point into the deep sclera directed to a previously prepared 20G anterior chamber paracentesis in the same radial axis, after passing through the paracentesis tunnel, exit from outer surface of the cornea. The suture ends are retrieved through the paracentesis and tied, allowing the knot to slide into the paracentesis tunnel.

Results:

We used this technique in 18 cases, there were no specific complications after development curve and standardization.

Conclusions:

We consider our technique for TSSF of intraocular implant to be less traumatic, eliminates the risk of possible complications associated with conjunctival and scleral dissection or suturing, simplifies the procedure and shortens operation time.
