Intrascleral Suture Anchoring: A Flapless/Grooveless Four-Point Intraocular Lens Fixation Technique.

ABSTRACT:

Purpose

We describe a minimally invasive suture fixation technique for four-point fixation of intraocular lenses (IOLs) in the treatment of aphakic eyes, namely, the intrascleral suture anchoring technique. Neither scleral flaps nor large conjunctival dissections are required.

Methods

This study included 11 eyes (11 patients). After looping the eyelets on the IOL haptics and externalizing the threads, the curved needle attached to the externalized thread was started with two sequential intrascleral passes from the first fixation point to reach the second fixation point. The same procedure was performed for the other side of the IOL. A fixation knot was created in the sclerotomy by the two ends of the thread to close the suture loop for IOL fixation. Another knot was created about 2 to 3?mm from the exiting point and was intrasclerally anchored by the aid of the attached curved needle.

Results

The mean postoperative follow-up period was 9.7?±?5.8 months (range 5-15 months). The IOLs of all eyes remained well positioned and stable postoperatively. The postoperative visual acuities were improved. No suture erosion, suture loosening, hypotony, scleral atrophy, chronic inflammation, retinal tear, and/or detachment were observed within the follow-up period.

Conclusion

The present technique is an alternative, flapless method for the four-point suture fixation of IOLs. It provides both minimal surgical trauma and reliable stability.

Project description:PurposeTo report two patients with a complication of Yamane intrascleral haptic fixation surgery (ISHF) with the Zeiss CT Lucia 602 lens: severely tilted intraocular lens (IOL) leading to significantly decreased vision in the early post-operative period.ObservationsWe report two patients presenting with severely tilted IOL implants one day and one month following Yamane ISHF. The first patient is a monocular 81-year-old woman referred for treatment of cornea edema. Initial surgery involved replacement of an anterior chamber lens with a CT Lucia 602 posterior chamber lens using Yamane technique and Descemet's stripping endothelial keratoplasty. The patient returned at one month follow-up with poor vision and IOL tilt observable at the slit lamp through a peripheral iridectomy site. Explanation of the Zeiss lens revealed haptic distortion at the optic-haptic insertion point such that each haptic was about 45° off axis to the plane of the optic in approximately equal and opposite directions. The second patient, a 75-year-old woman, was referred with a completely dislocated lens-bag complex in the right eye. The initial operative treatment for this patient included pars plana vitrectomy, retrieval and removal of the dislocated lens-bag complex, and placement of a Zeiss 602 lens via Yamane ISHF technique. On the first postoperative day, the patient was count fingers in the right eye with an intraocular pressure of 5 mm Hg and obvious IOL tilt on slit lamp examination. Explanation of the lens revealed severely distorted haptics relative to the optic by more than a 60-degree angle on both sides. In both cases, initial surgery was performed with an IOL inspected prior to implantation and found to have normal appearing haptics. At the end of each case, there was adequate centration and no tilt of the IOL. Management in both patients included removal of the defective lens and placement of a new, same power CT Lucia 602 lens via the Yamane technique. Visual acuity improved from CF to 20/30 best corrected after reoperation in both cases.Conclusions and importanceIn summary, we describe a complication of Yamane ISHF with the CT Lucia 602 lens in which there is lens tilting associated with distortion at the optic-haptic fastening zone in the early postoperative period. In the event of a titled lens following Yamane ISHF, awareness of this complication may help surgeons consider lens replacement, as the haptics may be permanently distorted or damaged.
