Łątkowska M, Gajdzis M, Kaczmarek R. Emulsification of Silicone Oils: Altering Factors and Possible Complications-A Narrative Review. J Clin Med 2024; 13:2407. [PMID: 38673681 PMCID: PMC11051299 DOI: 10.3390/jcm13082407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/16/2024] [Accepted: 04/18/2024] [Indexed: 04/28/2024] Open
Abstract
Background: Endotamponade of the vitreous body with silicone oil is a common procedure, being the basis of many vitreoretinal surgeries. However, emulsification may happen, which is a clinically relevant adverse event of silicone oil use. Methods: This review provides a thorough analysis of the emulsification process. It focuses on describing factors affecting this event as well as its possible subsequent complications. Results: The viscosity of silicone oil, the duration of emulsification, the status of the lens and many other factors have an influence on the onset and intensity of emulsification. This phenomenon carries several risks for operated eyes such as increased intraocular pressure, keratopathy or structural changes to the retina. Conclusions: The use of modern imaging techniques, especially optical coherence tomography, enables faster detection of the emulsification process. This allows for an adequate clinical response and more accurate follow-up of the patient.

Abstract
PURPOSE To introduce a surgical technique, "pound-shape silicone oil retention suture in aphakic eye with intact iris." METHODS A retrospective analysis of medical records was performed. Each patient had an aphakic eye with intact iris and received the pound-shape silicone oil retention suture during vitrectomy combined with silicone oil injection. RESULTS In the four patients who received the pound-shape silicone oil retention suture, the silicone oil was confined behind the suture for 3 months to 7 months without prolapse into the anterior chamber. Increased intraocular pressure was not observed in any patient, although peripheral iridectomy was not performed. CONCLUSION Pound-shape silicone oil retention suture is a simple and effective surgical technique to prevent silicone oil prolapse into the anterior chamber.

Evaluations of bridging sutures in preventing iris capture in eyes with intrascleral fixation of implanted intraocular lens. Graefes Arch Clin Exp Ophthalmol 2023; 261:427-434. [PMID: 36042055 DOI: 10.1007/s00417-022-05816-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 08/11/2022] [Accepted: 08/19/2022] [Indexed: 01/17/2023] Open
Abstract
PURPOSE The study aims to determine the effectiveness of bridging sutures in preventing iris capture and a subsequent reverse pupillary block after an intrascleral fixation of an implanted intraocular lens (IOL). METHODS We studied 6 eyes that had an iris capture with reverse pupillary block due to a dislocated IOL after an intrascleral fixation. After the dislocated IOL was repositioned, 10-0 polypropylene sutures were inserted 1.5 mm posterior to the limbus and directed to run between the iris and the IOL. The sutures were placed orthogonal to the haptics of the IOL. Anterior segment optical coherence tomography (AS-OCT) was used in 4 eyes to evaluate the degree of iridodonesis before and after the bridging sutures. The heights of the temporal and nasal sectors of the middle iris from the iris plane (the line between anterior chamber angles) were compared for each 0.2-s AS-OCT image taken immediately after the eye moved from a lateral to a primary position. RESULTS None of the eyes had a recurrence of the iris capture after the bridging sutures. The refractive error, anterior chamber depth, and vision were not significantly altered after the bridging sutures were placed. The AS-OCT images showed that the height of the nasal iris was decreased more at 0 s postoperatively blocking the excessive downward movement of the nasal iris but not the iridodonesis. CONCLUSION Bridging sutures were effective in preventing iris capture and subsequent reverse pupillary block after an intrascleral fixation of an IOL.

The Double-Deck Viscoelastic Technique: a Novel Surgical Technique to Protect the Corneal Endothelium in Penetrating Keratoplasty of Aphakic Silicone Oil-Dependent Eyes after Severe Ocular Injury. Ophthalmol Ther 2023; 12:613-623. [PMID: 36309624 PMCID: PMC9834487 DOI: 10.1007/s40123-022-00594-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 10/06/2022] [Indexed: 01/16/2023] Open
Abstract
INTRODUCTION The purpose of this study is to summarize the benefits of the double-deck viscoelastic technique (DDVT), a novel and cost-effective surgical technique that creates a barrier to hinder silicone oil (SO) from connecting and damaging the corneal endothelium in aphakic and SO-dependent eyes. METHODS Five SO-dependent and aphakic eyes underwent double-deck viscoelastic embedment and penetrating keratoplasty (PKP) in this retrospective case series. At 1, 6, 12, 18, and 24 months after surgery, clinical outcomes including best corrected visual acuity (BCVA), intraocular pressure (IOP), corneal endothelial cell density (ECD), and double-deck viscoelastic layer imaging were evaluated. A Heidelberg Retina Tomograph confocal microscope was used to measure ECD. Ultrasound biomicroscopy (UBM) was used to image the double-deck viscoelastic layer. RESULTS Postoperatively, the BCVA of the patients ranged from hand motion detection to 20/200, and their IOP was between 7 and 10 mmHg. The two-deck viscoelastic layer remained mostly static. Patients showed varying degrees of ECD reduction, with ECD loss rates in the first 6 months ranging from 6.7 to 75.8 cells/mm2/month and then declining to 2.2-14.3 cells/mm2/month. CONCLUSION In SO-dependent aphakic eyes, double-deck viscoelastic embedment could effectively inhibit SO-corneal endothelium interaction. This technique could lower the pace of ECD loss and lengthen the time of corneal transparency, giving aphakic and silicone oil-dependent patients the opportunity to accept PKP surgery and get better vision quality.

Abstract
Purpose: The purpose of this article is to discuss the early- and late-onset corneal complications that can occur following vitreoretinal surgery. Methods: A systematic review of the literature was conducted using PubMed and Google Scholar databases. Articles detailing the clinical findings and the associations between surgical techniques, irrigating solutions, and microsurgical instruments used for vitreoretinal surgery and postoperative corneal complications were included in this review. Results: Vitreoretinal surgery can be associated with corneal complications such as persistent corneal epithelial defects, neurotrophic keratopathy, band keratopathy, ocular surface disruption, and endothelial cell damage. Risk factors for the development of cornea complications after posterior segment surgery include history of uncontrolled diabetes mellitus, aphakia or pseudophakia, disrupted anterior lens capsule integrity, use of irrigating solutions without appropriate buffers, use of contact viewing lenses intraoperatively, intraocular gases or silicone oil after vitrectomy, and prolonged duration of surgery. Conclusions: Corneal complications secondary to vitreoretinal surgery are multifactorial, but more commonly arise in diabetic patients, those with preexisting ocular comorbidities, and under certain surgical-related conditions. Special pre-, peri-, and postoperative considerations, with a focus on early identification and management of risk factors, are required to help decrease the incidence of corneal complications.

Abstract
We aim to describe a technique for intraocular lens (IOL) implantation with suture clamping for aphakic capsules. This prospective, noncomparative, interventional case study included three eyes of three patients with an aphakic capsule after vitrectomy, in which the IOL was clamped by suturing. The suturing procedure was transconjunctival or subconjunctival performed without scleral flaps. The IOLs were implanted without difficulty, and visual acuity improved after IOL implantation. There were no severe complications, and the position of each IOL remained correct through 18 months of follow-up. The present technique is straightforward and effective in the treatment of eyes with an aphakic capsule.

Risk Factors for Band Keratopathy in Aphakic Eyes With Silicone Oil Tamponade for Open-Globe Injuries: A Multicenter Case-Control Study. Front Med (Lausanne) 2021; 8:713599. [PMID: 34368200 PMCID: PMC8342885 DOI: 10.3389/fmed.2021.713599] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2021] [Accepted: 06/30/2021] [Indexed: 11/13/2022] Open
Abstract
Band keratopathy (BK) is a common complication in aphakic eyes with silicone oil tamponade for open-globe injury (OGI), characterized by the grayish-white opacities in the cornea, resulting in a significantly decreased vision when extending to the visual axis. To identify the risk factors for BK in aphakic eyes following vitreoretinal surgical treatment with silicone oil tamponade for OGIs, we performed a multicenter case-control study. The incidence of BK was 28% (28/100 eyes). The multivariate binary logistic regression revealed the silicone oil retention time (SORT) ≥6 months and zone III injury were significant risk factors for BK. From the hierarchical interaction, SORT ≥6 months had a significant risk for BK in eyes with rupture, aniridia, and zone III injury, while zone III injury had a significant risk for BK in eyes with rupture, incomplete/complete iris, and SORT ≥6 months. By using restricted cubic splines with three knots at the 25th, 50th, and 75th centiles to model the association of SORT with BK, we also found a marked increase in the risk for BK at ≥10 months and a slow increase after 6 months, but almost stable within 4-6 months.

Surgical Management for Silicone Oil Barrier of Traumatic Aniridia with Aphakia: Suturing of Temporary Iris-Diaphragm Prior to Final Iris-Lens-Diaphragm Implantation. Clin Ophthalmol 2020; 14:4439-4450. [PMID: 33376298 PMCID: PMC7762446 DOI: 10.2147/opth.s284159] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Accepted: 11/24/2020] [Indexed: 12/30/2022] Open
Abstract
Purpose Patients with traumatic aniridia, aphakia and retinal complications can require silicone oil endotamponade. In the absence of compartmentalization, there is a risk of silicone oil migrating to the anterior chamber which can cause long-term complications. We report a two-step procedure in trauma cases, using sutures for silicone oil retention in primary care and subsequently prior to secondary artificial iris (AI) and intraocular lens (IOL) implantation, to achieve a reconstruction of the anterior and posterior chamber. Material and Methods Seven patients with loss of the iris-lens-diaphragm after an ocular trauma and the need for silicone oil endotamponade underwent a primary intervention including wound closure, placement of silicone oil retention sutures and silicone oil filling. Four of those underwent secondary reconstruction with silicone oil removal and AI and IOL implantation and could be included in this retrospective observational study. All main outcome measures were evaluated after the first and after the second surgery. The main outcome measures were morphological findings, subjective impairment from glare, subjective cosmetic disfigurement, patient satisfaction and intraocular pressure (IOP) as well as best-corrected distance visual acuity and objective refraction. Results The retention sutures could effectively prevent silicone oil migration into the anterior chamber in the first surgery. Silicone oil emulsifications in the anterior chamber were observed in one patient. In two patients, pigment deposition at the sutures was seen. Subjective impairment from glare and subjective cosmetic disfigurement could be reduced after the second surgery compared to the evaluation after the first surgery. IOP and best-corrected distance visual acuity remained stable. No eye needed silicone oil refilling after the secondary reconstruction surgery. Conclusion Our two-step approach is viable and provides good functional and aesthetic results. We observed a high patient satisfaction.
