Abstract Details

Purpose:

The propose our work is create the method retention sutures for support and stability the subluxation lens in during phacoemulsification. As well, the retention sutures used as net for fixation the tree piece IOL inside the eye when the lens material had completely removed.

Setting:

Phacoemulsification cataract with lens subluxation is still causing difficulties. The first problem is a complete removal of the lens material without sinking the part of it into the vitreal cavity. The second challenge is fixation of the IOL in the eye without any capsules.

Methods:

At first, we placed three standard vitreous valve ports 25 G or 23 G. Then, we made the U shape suture with 9/0 Many needle. The needle put in to sclera at a distance of 3 mm from the limbus through the eye under the lens towards the opposite limbus. When the pic of needle appears from the eye it grasped by the forceps and the needle pulled from eye. Next stitch was from this limbus to another by the same way. Two stitches were as rule on sides of the optical zone with 4 mm distance from each other.

Results:

We performed this method in 6 cases (6 eyes) with different stage of lens subluxation. After that It was possible almost completely remove the lens, by standard phacoemulsification in 5 eyes (83%). We used the core vitrectomy for remove small debris of nucleus with vitreal body. The essential fragment of lens sank in the one case (17%). In this case, we applied the PFCl to lifted the fragment and then removed it by the probe of phacoemulsificator. In all cases, we implanted the soft three-piece IOL with a fixation on the retention U shaped sutures.

Conclusions:

The method of the U-shape retention sutures was effective and helpful for subluxation lens surgery. It prevent the lens from drowning in the vitreous cavity in most cases in during phacoemulsification. In addition, U- shape sutures are the perfect frame for the subsequent fixing of the soft three-piece IOL.
