ABSTRACT

We aimed to test a novel concept based on multiple IOL-implantation, targeting spectacle independence for patients with high and excessive myopia (26.0 mm < axial length; 6.0 D < refractive error). Therefore, we introduced the first results of five patients with high myopia. After clear lens extraction, one eye was targeted to emmetropia, and the other to mild myopia by implanting monofocal capsular bag IOLs with appropriate refractive powers in each case. The emmetropic eye was aimed to result in magnification and improved distance vision, while the mild myopic eye was supposed to ensure good intermediate vision. Thereafter, a Scharioth Macula Lens (SML) was implanted into the emmetropic eye in order to achieve sharp near vision. Visual acuity curves and defocus curves were plotted postoperatively. According to our results, this new concept seems to be an efficient approach of achieving appropriate uncorrected vision at all distances, by creating binocular trifocal monovision.

ABSTRACT

The modern glaucoma surgeon is faced with many surgical alternatives for the management of glaucoma. In recent years, numerous techniques that make Schlemm's canal (SC) more accessible for surgery by being less invasive and surgically less challenging were introduced. Since its first introduction, canaloplasty has become a well-established method of glaucoma surgery. The aim of this paper was to present an overview of canaloplasty and its modifications, and to highlight their strong points and potential drawbacks based on available data on the effectiveness of each technique. Furthermore, it offered an overview of the development of canaloplasty over time and the clinical aspects that should be considered in patient selection. Abbreviations: ABiC = Canaloplasty ab interno, AH = aqueous humour, CSD = Canaloplasty with suprachoroidal drainage, IOP = intraocular pressure, MIGS = minimally invasive glaucoma surgery, OAG = open angle glaucoma, PEXG = pseudoexfoliation glaucoma, SC = Schlemm's canal, TDM = trabeculo-Descemet's membrane.

ABSTRACT

Objective: To compare the number of surge events and efficacy of phacoemulsification using a near-physiological intraocular pressure (IOP) setting and a standard IOP setting. Materials and methods: The surgical data of patients who underwent phacoemulsification with IOL implantation using the CENTURION Vision System's Active Fluidics setting and Active Sentry Handpiece (Alcon Laboratories, USA) were analyzed. Results: The study included 181 patients (204 eyes). In Group 1, the IOP was set at 20 mmHg (n=102, 50%), and in Group 2, the IOP was set at 60 mmHg (n=102, 50%). Total case time was significantly lower (p=.036) in Group 1 (0:03:17.20 ± 0:00:34.55 vs. 0:03:28.71 ± 0:00:43.03). There was no statistically significant difference between the mean cumulative dissipated energy (CDE) (7.06 ± 3.20 vs. 7.59 ± 3.26) and mean ultrasound (UJS) time (0:00:36 ± 0:00:12 vs. 0:00:38 ± 0:00:13) between the two groups (p=0.24 and p=0.31, respectively). Active sentry (AS) engaged less often (p<0.001) in Group 1. There was no statistically significant correlation between the CDE and AS activation in Group 1 (p=0.96). A strong statistically significant correlation between the CDE and AS activation (p<0.0001, r=0.61, CI (0.47 to 0.72)) was observed in group 2. Conclusion: During phacoemulsification, surge events are more likely to occur when operating at high IOP settings.

ABSTRACT

OBJECTIVE: To report the visual and refractive outcomes following monocular implantation of a supplementary (piggyback) Scharioth macula lens (SML) in previously pseudophakic eyes with age-related macular degeneration (AMD). METHODS AND ANALYSIS: Prospective European multicentre clinical trial. 50 eyes of 50 pseudophakic patients with either dry or previously treated and stable neovascular AMD for at least 6 months were included. The inclusion criteria were age over 55, corrected distance visual acuity (CDVA) of 0.4-0.1 (decimal), improvement of at least three lines of corrected near visual acuity (CNVA) when tested with a +6.0 dioptre (D) reading addition at 15 cm, compared with a +2.5 D reading addition at 40 cm using a standardised, self-illuminated Early Treatment Diabetic Retinopathy Study near vision chart. The SML intraocular lens (IOL) was implanted as an add-on/piggyback IOL in the ciliary sulcus, monocularly in the better seeing eye of each subject meeting the inclusion criteria. RESULTS: There were no intraoperative complications. One subject had the SML explanted in the postoperative period due to postoperative glare/halos. The mean CNVA improved from 0.23±0.12 (decimal) preoperatively to 0.57±0.33 at 1 year. The mean CDVA remained unchanged measuring 0.19±0.13 preoperatively and 0.19±0.09 at 1 year postoperatively. CONCLUSION: The SML appears to be safe and effective in improving the CNVA in patients with AMD. Data suggest that the CDVA remains unaffected following implantation. Further data are needed to assess the long-term safety and efficacy.

ABSTRACT

UNLABELLED: We present a new option for visual rehabilitation of patients with advanced macular degeneration and evaluate the outcomes in the first 8 patients who had implantation of the ciliary sulcus-fixated macular add-on intraocular lens (IOL) (Scharioth Macula Lens) at our institute. The surgical technique for implantation of the add-on IOL is described. Near vision improved in 7 eyes and was stable in 1 eye. The corrected near visual acuity improved by 4.4 lines with the macular add-on IOL at 15 cm versus with glasses at 40 cm; it improved by 2.1 lines with the macular add-on IOL at 15 cm versus with glasses at 15 cm. Distance vision was stable in all eyes. No intraoperative or postoperative complication occurred. The macular add-on IOL has the potential of improving near vision and reading ability in patients with advanced age-related macular degeneration. FINANCIAL DISCLOSURE: Dr. Scharioth is a consultant to Alcon Laboratories, Inc., and Medicontur Ltd. He is the inventor of the Scharioth Macula Lens and receives royalties.

ABSTRACT

Purpose. To report one-year results of phacoemulsification combined with deep sclerectomy and goniosynechiolysis ab interno for chronic glaucoma associated with peripheral anterior synechiae (PAS). Methods. We retrospectively analyzed medical charts of 16 patients (20 eyes) treated by one-site combined phacoemulsification and deep sclerectomy with goniosynechiolysis ab interno. PAS were transected by a spatula introduced into the anterior chamber through a paracentesis. To account for the correlation of right and left eyes a linear mixed model with unstructured covariance structure was calculated. Results. The mean preoperative intraocular pressure (IOP) was 20.3 ± 5.2 mmHg with 2.4 ± 1.0 medications. One year postoperatively, the mean IOP was 15.3 ± 3.3 mmHg (P = 0.004, paired t-test) with 0.6 ± 1.0 medications. A postoperative IOP of ≤21 mmHg without medication was achieved in 17 of 19 eyes (89.5%) and in 12/19 eyes (63.2%) at 3 and 12 months after surgery, respectively. In the remaining eyes (10.5% at 3 months and 36.8% at 12 months), additional medication led to an IOP ≤21 mmHg or the target pressure. No case required further glaucoma surgery. In one eye, conversion of the surgery to trabeculectomy was necessary due to Descemet's window rupture. Conclusions. With goniosynechiolysis ab interno, effective and safe nonpenetrating glaucoma surgery is possible in presence of PAS.

ABSTRACT

PURPOSE: To evaluate the feasibility of two novel 'heavy' dye solutions for staining the internal limiting membrane (ILM) and epiretinal membranes (ERMs), without the need for a prior fluid-air exchange, during macular surgery. METHODS: In this prospective nonrandomized multicenter cohort study, the high molecular weight dyes ILM-Blue™ [0.025% brilliant blue G, 4% polyethylene glycol (PEG)] and MembraneBlue-Dual™ (0.15% trypan blue, 0.025% brilliant blue G, 4% PEG) were randomly used in vitrectomy surgeries for macular disease in 127 eyes of 127 patients. Dye enhanced membrane visualization of the ILM and ERMs, 'ease of membrane peeling', visually detectable perioperative retinal damage, postoperative best-corrected visual acuity (BCVA), dye remnants and other unexpected clinical events were documented by 21 surgeons. RESULTS: All surgeries were uneventful, and a clear bluish staining, facilitating the identification, delineation and removal of the ILM and ERMs, was reported in all but five cases. None of the surgeries required a fluid-air exchange to assist the dye application. BCVA at 1 month after surgery improved in 83% of the eyes in the MembraneBlue-Dual™ group and in 88% in the ILM-Blue™ group. No dye remnants were detected by ophthalmoscopy, and no retinal adverse effects related to the surgery or use of the dyes were observed. CONCLUSION: The 'heavy' dye solutions ILM-Blue™ and MembraneBlue-Dual™ can be injected into a fluid-filled vitreous cavity and may facilitate staining and removal of the ILM and/or ERMs in macular surgery without an additional fluid-air exchange.

ABSTRACT

PURPOSE: To present a technique for sutureless fixation of a three-piece, multifocal, posterior chamber intraocular lens (IOL) in the ciliary sulcus. METHODS: A 24-year-old woman presented with bilateral subluxation of the crystalline lens. Two straight sclerotomies were prepared with a 24-gauge cannula 2.0 mm from the limbus 180° apart from each other. The cannula was used to create a 2.0- to 3.0-mm tunnel parallel to the limbus starting from the sclerotomies. The leading haptic of the multifocal IOL was grasped at its tip with end-gripping, 25-gauge forceps and pulled through the sclerotomy. The forceps was used to introduce the IOL haptic into the scleral tunnel parallel to the limbus. RESULTS: Multifocal posterior chamber IOLs were stable and well centered. No postoperative complications occurred in the 16-month follow-up period. Preoperative astigmatism was corrected after IOL implantation with corneal wavefront-guided laser epithelial keratomileusis. CONCLUSIONS: Sutureless fixation of multifocal posterior chamber IOL haptics in a scleral tunnel parallel to the limbus can be successful, resulting in long-term centration and three-dimensional axial stability for optimal refractive results. If necessary, postoperative wavefront-guided refractive correction can be performed to optimize final refraction.

ABSTRACT

PURPOSE: To report the intermediate multicenter results of a technique of sutureless intrascleral fixation of a standard 3-piece posterior chamber intraocular lens (PC IOL) in the ciliary sulcus. SETTING: Four European ophthalmology centers. METHODS: A technique for sutureless intrascleral fixation of the haptics of a standard 3-piece PC IOL was retrospectively evaluated. The technique uses standardized maneuvers to fixate the PC IOL without need for special haptic architecture or preparation or haptic suturing. All patients having IOL implantation by the technique were evaluated for preoperative status (visual acuity, refractive error, preexisting ocular conditions, optical biometry), postoperative status, complications, and need for further surgery. RESULTS: The study evaluated 63 consecutive patients from 4 institutions (4 surgeons). The median follow-up was 7 months. Two dislocated PC IOLs (3.6%) were decentered; the other 61 IOLs (96.8%) were stable and well centered. There were no cases of recurrent dislocation, endophthalmitis, retinal detachment, or glaucoma. CONCLUSION: Fixation of PC IOL haptics in a limbus-parallel scleral tunnel provided exact centration and axial stability of the IOL and prevented distortion and subluxation in most cases.

ABSTRACT

BACKGROUND: The purpose of this study was to report the adverse effect of iridolenticular block glaucoma after vitreoretinal surgery and endotamponade with heavy silicone oil in cases of complicated retinal detachment. METHODS: A retrospective analysis of 23 eyes of 23 patients who underwent a pars plana vitrectomy and heavy silicone oil (Densiron 68) endotamponade for repair of complex inferior retinal detachment. RESULTS: Two patients developed high intraocular pressure postoperatively. The mechanism of secondary glaucoma in both patients was a prolapse of heavy silicone oil into the anterior chamber. When lying in a supine position for a prolonged period, the heavy silicone oil occluded the pupil, causing an iridolenticular block. CONCLUSION: In the presence of heavy silicone oil in the anterior chamber, lying in a supine position causes the oil drop to sink, blocking the entire diameter of the pupil, and inducing an iridolenticular block with acute angle-closure glaucoma. We conclude that every case of heavy silicone oil migration into the anterior chamber should be regarded as an emergency. The possible treatment could include pupil dilation, anterior chamber irrigation, or an Nd YAG-laser iridotomy.

ABSTRACT

OBJECTIVE: To evaluate the early effects of triamcinolone acetonide (TA) on inflammation, proliferation, and vascular endothelial growth factor (VEGF) in human choroidal neovascularization (CNV). METHODS: Retrospective review of an interventional case series of 29 patients who underwent macular translocation. Fourteen CNV membranes without previous therapy (control CNV group) and 4 CNV membranes excised 3 days after photodynamic therapy (PDT CNV group) comprised the control groups. Eleven patients were treated with intravitreal TA (TA CNV group; n = 5) or PDT and TA combined (PDT+TA CNV group; n = 6) 3 to 9 days preoperatively. The CNV membranes were stained for cytokeratin 18, CD34, VEGF, intercellular adhesion molecule-1 (ICAM-1), E-selectin, CD68, CD45, Ki-67, and Thy-1. RESULTS: Treatment with TA and PDT+TA resulted in increased immunostaining of ICAM-1 in endothelial cells and the stroma and a higher percentage of Thy-1 expression than controls. The density of macrophages was significantly increased in PDT+TA CNV membranes. Leukocyte density and proliferative activity were lower in TA and PDT+TA CNV membranes. The total VEGF score was significantly increased in TA and PDT+TA CNV membranes compared with the control CNV membranes. Evidence of VEGF in the retinal pigment epithelium of PDT+TA CNV membranes was stronger than in control CNV membranes. CONCLUSIONS: Triamcinolone acetonide has no inhibitory effect on macrophage infiltration or ICAM-1, Thy-1, or VEGF expression in CNV membranes in the early term. The clinical benefits of TA are probably not based on pure antiinflammatory or VEGF-suppressing mechanisms.
