Results in comparison between 30 gauge ultrathin wall and 27 gauge needle in sutureless intraocular lens flanged technique in diabetic patients: 24-month follow-up study.

AIMS: Intraoperative complications in cataract surgery are more common in diabetic patients. Solving aphakia in these circumstances remains a challenge, as the scleral structure has been shown to be different in diabetes. This study aims to analyze the role of a secondary sutureless scleral intraocular lens (IOL) flanged fixation in diabetic patients without capsular support and to compare the anatomical and functional outcomes using a 30 gauge (G) ultrathin wall needle vs. a 27G needle. METHODS: Retrospective, observational cohort study. 105 eyes (105 patients) who underwent PPV with secondary IOL fixation using a sutureless 27G (n = 51) or a 30G ultrathin wall (UTW) needle technique (n = 54) and had a 24 months postoperative follow up. Consecutive patients' records were reviewed for lens stability and centration parameters, intra- and postoperative complications at 7 days, 1, 3, 6, 12, and 24 months after surgery. Correlations between outcome measures and needle size (27G vs. 30G UTW) were analyzed. RESULTS: IOL displacement occurred in 30 patients (41.2%) in the 27G group and did not occur in the 30G UTW needle group (p < 0.001). Mean time until IOL displacement was 10.5 ± 7.0 months (range: 7 days-24 months). IOL centricity was significantly better in the 30G ultrathin wall needle group compared to 27 G (p = 0.001). Additional surgical interventions were necessary only in the 27G group (n = 14). CONCLUSIONS: Sutureless IOL flanged technique using a 30G UTW needle is more predictable and has less complications in aphakic diabetic patients, compared to a 27G needle technique.

Deep and Superficial Closure.

All operative interventions in plastic surgery have one thing in common: closure of an incision or wound at the conclusion of the procedure. For many years, the only option to accomplish this task was the use of sutures. Today's surgeon, however, has many more options available, ranging from smooth to barbed suture, external to internal staples, internal to external adhesive glues, and incisional negative-pressure wound therapy. These devices are designed with the goal of making wound closure more rapid and secure, and decreasing postoperative sequelae. This paper reviews methods available to perform incisional closure and the published clinical data regarding their use.
