<p>Intraocular Lens Implantation In The Ciliary Sulcus: Challenges And Risks</p>

Abstract

PurposeThis article reviews the current literature on the risks and challenges associated with intraocular lens (IOL) implantation in the ciliary sulcus.Recent findingsThe development of IOLs designed specifically for placement in the ciliary sulcus continues to be an area of interest for the ophthalmic industry. Currently the one-piece PMMA (polymethylmethacrylate) lens or a three-piece IOL are the best available options for IOL placement in the ciliary sulcus space. Single piece acrylic (SPA) IOLs are not designed for sulcus placement and there is growing evidence of chronic complications related to their use in the ciliary sulcus. Many of these eyes ultimately require surgical intervention, including lens exchange. Endoscopic imaging and ultrasound biomicroscopy (UBM) have enabled a better understanding of ciliary sulcus anatomy and measurements in the living eye.SummaryWhen the capsular bag is compromised, IOL placement in the ciliary sulcus is a reasonable option. In these circumstances, appropriate choice of IOL, knowledge of the sulcus anatomy, and correct technique can improve results and reduce postoperative complications.

Secondary Piggyback Intraocular Lens for Management of Residual Ametropia after Cataract Surgery

“…[15] Furthermore, this procedure achieves the best results when performed soon before the formation of capsular adhesions, which is not feasible in all patients. [4,7,10] Recently, secondary piggyback IOL implantation has received more attention due to its promising safety profile and easier surgical techniques. [6,[15][16][17][18] Additionally, there are many studies reporting predictable refractive outcomes with the application of power calculation of the second IOL, which is not very complicated.…”

“…[4,7] However, the increased risk of glaucoma, iris pigment release, and intralenticular opacification make this procedure controversial for many surgeons. [8][9][10][11] Piggyback IOL implantation is considered primary when the refractive error is higher than can be corrected with one IOL and secondary when the residual refractive error is corrected. In secondary piggyback IOL implantation, in which the second IOL is placed in the ciliary sulcus, different IOL designs and types are used, including monofocal, multifocal, and toric.…”

Reversibility of the duet procedure: Bilateral exchange of a supplementary trifocal sulcus-fixated intraocular lens for correction of a postoperative refractive error

“…Therefore it is recommended to choose an IOL specifically designed for implanting into the ciliary sulcus. 13 An important feature of supplementary IOLs is the changed optical design, away from the biconvex to the convex-concave design. The concave posterior optic surface shape prevents interlenticular opacification by providing space between the supplementary lens and the primarily implanted IOL.…”

Retrospektywna ocena powikłanych operacji zaćmy z implantacją na torebkę przednią jednoczęściowych zwijalnych soczewek wewnątrzgałkowych

“…Na podstawie pomiarów anatomicznych uważa się, że średnica bruzdy ciała rzęskowego wynosi 11-12,5 mm [16,17]. Jak wynika z piśmiennictwa, wymiar soczewki powyżej 12,5 mm może zapewnić stabilną pozycję implantu [18]. Stosowana jest również technika optic-capture, która polega na umieszczeniu haptyków na torebce przedniej, podczas gdy część optyczna pozostaje za torebką [19,20].…”
