Article Abstract
Purpose: This study describes a novel loop and sliding knot technique for the scleral fixation of the Akreos Adapt AO intraocular lens (IOL).
Methods: A 27G needle was inserted into the eye from two ipsilateral fixation sites, and passed through the IOL eyelet, exiting from the same limbus incision. The suture was pulled out and inserted into the needle to form a loop. A 26G needle guided the suture to pass through the superficial sclera between the two fixation sites. Part of the suture was pulled out and tied to the free suture to form a sliding knot. The knot was then buried in the scleral tunnel.
Results: A total of 12 patients (12 eyes) underwent this technique. The logarithm of the minimum angle of resolution (logMAR) for preoperative corrected visual acuity was 0.75 ± 0.62 (Snellen 20/112), which improved to 0.25 ± 0.24 (Snellen 20/35) at the final follow-up. The mean postoperative posterior chamber IOL tilt was 2.64 ± 1.28°. There were no cases of pupillary capture or suture-related complications during the follow-up period.
Conclusion: The loop and sliding knot technique offers a simple and minimally invasive method for the four-point fixation of the Akreos Adapt AO IOL.

To assess the 1-month outcomes of visual performance and positional stability of capsule-fixated intraocular lenses (IOLs) in patients with IOL-Bag complex dislocation. We enrolled 36 eyes (34 patients) with IOL-Bag complex dislocation due to pseudoexfoliation syndrome. Patients with intraoperative complications or prior posterior capsule Nd-YAG laser were excluded.

Arthroscopic knot-tying is an important skill for any arthroscopist. Many types of knots have been proposed, each with various advantages and disadvantages. The Samsung Medical Center (SMC) knot is an arthroscopic sliding knot featuring a self-locking loop that has been demonstrated to have good knot security and a low-profile construct.

A rise in knot-related complications in the 1970s due to the growing number of synthetic sutures available to surgeons led to the experimental study of the security of tied surgical knots. Great progress in the understanding of the effect of knot configuration on knot security has been made since that time, but the findings have had uneven penetration both among and within the various surgical specialties. The emergence of multiple different knot-tying lexicons as well as inconsistencies between the verbal descriptions and illustrations of some of these lexicons presents a challenge to surgeons interested in learning about the subject.
