Purpose:
To develop a novel, sutureless, single-piece, nonfoldable intraocular lens (IOL) intrascleral fixation technique based on the existing Malbran IOL scleral fixation and Yamane double-needle techniques.
Methods:
The novel method uses a 5.0 polypropylene suture and a bipolar cautery to create 2 flanges in the eyelets of the IOL and 2 flanges outside to insert inside the scleral tunnel and thus fixate the IOL.
Results:
This technique had been applied in 4 patients with aphakia after phacoemulsification complications. The mean preoperative and postoperative corrected distance visual acuities were 0.45 ± 0.17 and 0.67 ± 0.27 (Snellen decimal units), respectively.
Conclusions:
The 4-flanged technique improves and simplifies the existing single-piece, nonfoldable IOL intrascleral fixation techniques.
A new technique for fixating the capsular bag in patients with ectopia lentis is presented. In this technique, the capsulorhexis is performed using a femtosecond laser, followed by the insertion of a standard capsular tension ring to redistribute capsular forces. The nucleus is hydroprolapsed into the anterior chamber and nuclear disassembly is performed above the iris plane to reduce zonular stress. Finally, a 5-0 polypropylene monofilament is used to fixate a capsular tension segment and subluxated capsular bag. This novel double-flanged method, achieved with cautery, does not require direct suturing of the monofilament on the sclera. This article describes the use of this new technique in 3 eyes, 2 in patients with Marfan syndrome and 1 in a patient with microspherophakia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
