Abstract Details

Purpose:

Propose a new surgical technique for the management of the late in-the bag intraocular lens (IOL) complex.

Setting:

Ophthalmology Service. La Mancha-Centro Hospital. Alcázar de San Juan. CR, Spain

Methods:

Prospective study (21,1 average months of follow up) of 9 patients (65,2 average age, 8 males/1 female) who previously undergone cataract surgery (7,8 years on average) with late in-the bag IOL luxation. Preoperative mean visual acuity was 0,26. In all cases this microsurgical approach (CHST) was used in combination with 25 or 23G 25-g vitrectomy system. The CHST consists in grasping and binding both haptics of the IOL (single or three pieces IOLs) with a 10-0 polypropilene suture, with the help of two disposable 25 or 23-g vitreoretinal microforceps, and suturing beneath a deep scleral flap to avoid photosuturolysis.

Results:

Repositioning of the in-the bag IOL complex in its anatomical site was achieved. Mean postoperative visual acuity improved to 0,53. No luxation recurrence was reported at last follow up.

Conclusions:

This new surgical approach could be a good option for improving visual and anatomical results for late in-the-bag IOL dislocation. Using a simple intraocular cow hitch knot, all of the objectives could be achieved: managing the bag-IOL complex, repositioning of the dislocated IOL, and preserving the capsular bag and the ocular anatomical compartmentalization.
