Iris-fixated lenses were first described in 1954 ("collar stud": Epstein 1954, "iris-clip": Binkhorst 1959). In the early 1960s, Collar implanted the first iris-fixated lens after an intra-capsular cataract extraction, but in 1971, Worst came in with the Iris Claw lens, and its modification evolved in the Artisan lens. [6] [7] Iris claw lens is an effective, predictable and safe option for ...

Iris-fixated intraocular lens is an intraocular lens that is implanted surgically into the eye and attached to the iris. Originally developed for aphakia, phakic versions have also been produced to correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

2006年9月1日 · Iris suture fixation is also useful for treating the increasing number of cases of late in-the-bag IOL dislocation, a complication that appears to be related to the advent of continuous curvilinear capsulorhexis. 1 “Rather than taking the [dislocated] lenses out and using big incisions, iris fixation can be used in many of those cases as well ...

Iris-fixated intraocular lenses (IOL) use the patient’s iris to support secondary lenses in the absence of adequate capsular support. They may be positioned anteriorly (in front of the iris) or posteriorly (retropupillary location).

2020年1月3日 · A chart review and data analysis of eyes that underwent iris fixation of posterior chamber (PC) IOL for correction of aphakia, dislocated and subluxed IOLs, ectopia lentis, and IOL exchange.

Implantation of intraocular lens with Iris-fixation is a safe, efficient and predictable surgical procedure, which empowers the refractive surgeon with singular capabilities. Among their advantages are the reversibility, preservation of ...

2024年10月30日 · Background/Objectives: To compare the clinical outcome of suture and sutureless iris fixation techniques for dislocated intraocular lenses (IOLs). Methods: Retrospective cohort study including patients who underwent surgery for late IOL dislocation over a 10-year period. IOL repositioning was achieved either by suturing the original IOL to the iris using the Siepser slipknot technique or by ...

This study is a meta-analysis comparing the efficacy, predictability, and safety of correcting myopia via implantation of two types of phakic intraocular lens (PIOLs): the implantable collamer lens (ICL) and iris-fixed PIOL. The Cochrane library, ...

2012年8月15日 · The IOL haptics provide an adequate fixation point for securing the lens to the peripheral iris. Because specially made lenses for iris suturing do not fold, many retina surgeons prefer to use traditional three-piece IOLs that can be folded and inserted through a …

2023年3月3日 · Single haptic iris fixation technique is used where there is a loss of 6 clock hours anterior capsular support. It helps the anterior segment surgeon to fix the intraocular lens to the iris on the side of absent capsular support and place the other haptic ...
