Gore‑Tex scleral IOL technique

A scleral-sutured intraocular lens is basically the backup plan when the eye’s natural capsular bag can’t hold a lens anymore. That happens in aphakia, trauma, prior complicated cataract surgery, or a dislocated implant. On May 7, Patrick Commiskey, MD, posted a video walking through one version of that rescue operation — secondary fixation of an Alcon CZ70BD lens using Gore-Tex sutures. The point of the technique is simple: keep the lens in the posterior chamber, keep it centered, and keep it there for years. ### What is this operation actually for? This is for eyes with poor or absent capsular support — meaning the normal scaffold for an intraocular lens is gone or unreliable. In that setting, surgeons usually choose among anterior chamber lenses, iris-fixated lenses, or scleral-fixated lenses. Scleral fixation is attractive because it keeps the lens farther from the cornea and angle, which can matter in younger patients and in eyes already prone to glaucoma, corneal trouble, or inflammation.

Those eyelets are the whole appeal here — they give the suture a defined place to sit, which makes fixation more controlled. The tradeoff is that PMMA is not foldable, so the surgeon needs a large incision, around 7 mm, instead of the smaller wounds used for foldable lenses like the Akreos or enVista.

Gore-Tex — expanded polytetrafluoroethylene — got popular because it is strong, easy to see, easy to handle, and has shown little evidence of late breakage in ophthalmic use. That matters because older scleral-sutured lenses raised long-term anxiety about suture fatigue and late redislocation. The catch is that Gore-Tex is being used off-label in the eye, and if the knot or suture ends are left exposed, erosion can still become a real problem.

The standard Gore-Tex playbook is to mark fixation points a few millimeters behind the limbus and keep the sclerotomies symmetric. If those passes are off, even by a little, the lens can tilt or decenter. Four-point fixation helps because tension can be adjusted from multiple directions instead of letting the lens rock on two unsupported points. (aao.org) ### Why is vitrectomy part of the story? Because vitreous is the enemy here. Any residual vitreous around the wounds or sutures can tug on the lens, distort the pupil, or raise the risk of hemorrhage and retinal complications. That is why these cases are often paired with anterior vitrectomy or full pars plana vitrectomy, especially when the eye already has a dislocated lens or prior posterior-segment disease.

The usual list is not trivial — hypotony from leaking sclerotomies, vitreous hemorrhage, cystoid macular edema, retinal detachment, pressure problems, decentration, and suture or knot exposure. Some series have shown good tolerance and low rates of suture-related failure, but more recent reports also describe exposed Gore-Tex sutures that needed patch-graft management. So the operation is durable, not carefree. (retinatoday.com) ### Why does this video matter now? Because this is the kind of surgery that lives or dies on small technical choices, not on the headline idea. Commiskey’s video is useful as a procedural map for a real-world rescue case — patient selection, eyelet-based fixation, centration strategy, and the complications worth actively trying to prevent. ### Bottom line This is not a flashy new device. It is a durable salvage technique for eyes that have run out of easy options. (retinatoday.com) When the measurements are clean and the sutures stay buried, a Gore-Tex-sutured CZ70BD can put a lens back where it belongs — but the margin for sloppiness is tiny. (youtube.com)
