Technique eliminates intraocular knotting in IOL suture fixation

A modified technique for scleral fixation of an IOL can eliminate difficult intraocular maneuvers and reduce the amount of time the eye is open, according to a group of surgeons.
“These advantages are realized by creating intraocular suture loops in preparation for PC IOL placement before creating a limbal incision,” reported Ruben Grigorian, MD, and colleagues at the New Jersey Medical School in a recent publication.
The intraocular suture loops are externalized, passed through the eyehooks of the haptics and fixated to the haptic in a manner that eliminates the need for intraocular knot-tying, the authors said.
Dr. Grigorian and colleagues described the use of their modified technique in 24 eyes undergoing posterior chamber IOL implantation without capsular support. Anatomical and functional outcomes of surgery were determined during a follow-up of 2 to 40 months.
Of 18 eyes that were followed for more than 6 months, four achieved final visual acuity of 20/40 or better. Final VA improved in nine eyes, did not change in eight eyes and worsened in one.
In all 24 eyes, the IOL remained well centered and without tilt at 1 month. Intraocular pressure of less than 8 mm Hg was present in six eyes immediately after surgery, and IOP normalized spontaneously in all eyes.
Among the postoperative complications were mild vitreous hemorrhage, choroidal detachment, anterior uveitis, hyphema, bleeding from the suture tract, corneal edema, cystoid macular edema, proliferative vitreoretinopathy with retinal detachment and irregular corneal astigmatism.
“Comparison of the results of this small series with those in the reported literature indicates that this technique is relatively safe and effective,” the authors report in the July issue of Ophthalmology.
