Iris Claw

An iris-claw intraocular lens (IOL) has been widely used as a secondary implant in aphakic patients. The study presents the results of implanting the anterior chamber iris-claw Artisan IOL in cases of where an appropriate posterior capsular support is lacking. The study included 132 patients subjected to primary IOL implantation during complicated cataract surgery with damage to the posterior capsule (I), secondary implantation in aphakia (II), secondary implantation during penetrating keratoplasty (III), and secondary implantation during pars plana vitrectomy with luxated IOL extraction (IV). We analyzed the records of best-corrected visual acuity (BCVA), spherical equivalent (SE), intraocular pressure (IOP), and corneal endothelial cell count (cECC), taken before and 1, 2, 3, and 4 years after the surgery. BCVA depended on the time after IOL implantation and the primary indication. Four years post-surgery, the SE values were the lowest in group III. IOP was the same in all groups both before and after the surgery, but 4 years after the surgery IOP values in group IV were higher than in group III. The cECC decreased every year after the surgery in all groups, but four years after the IOL implantation, the lowest cECC values were observed in group IV. At the same time, all groups of patients showed improved BCVA, stable refraction, and a low percentage of postoperative complications.

AbstractWe aimed to investigate the efficacy and safety of primary retropupillary iris claw intraocular lens (R-IOL) implantation in patients with complete intraocular lens (IOL) dislocation. In this single-center retrospective case series, we reviewed the medical records of patients who underwent R-IOL implantation surgery with pars plana vitrectomy for the treatment of IOL dislocation between September 2014 and July 2019. The primary outcome was change in visual acuity (VA) up to 24 months postoperatively. The secondary outcomes included changes in intraocular pressure (IOP), refractive errors, and endothelial cell count (ECC) over the same period. Data of 103 eyes (98 patients) were analyzed. The mean uncorrected VA was significantly improved at one month postoperatively (− 0.69 logMAR, P < 0.001), compared to the preoperative value. IOP (− 2.3 mmHg, P = 0.008) and ECC (− 333.4 cells/mm2, P = 0.027) significantly decreased one month post-surgery and remained stable thereafter. Postoperative mean spherical equivalents were similar to the prediction error throughout the follow-up period. IOP elevation (n = 8, 7.8%), cystoid macular edema (n = 4, 3.9%), and dislocation of the R-IOL (n = 10, 9.7%) were managed successfully. Overall, primary R-IOL implantation with pars plana vitrectomy is effective and safe for correcting IOL dislocation due to various causes.

Background: The surgical case of a dropped intraocular lens inside the vitreous cavity constitutes a real challenge for the operating surgeon. Herein, we describe a case series where an alternative optical rehabilitation technique for late intraocular lens-bag complex dislocation has been used. Methods: A modern vitrectomy device was used to remove the capsule with the dropped intraocular lens using sutureless 25-gauge pars plana vitrectomy. To ensure a better aesthetic result, with faster patient recovery and a reduced number of operations, the whole procedure was performed during the same operating session; an iris-claw intraocular lens for aphakia was selected for implantation. The implant was passed behind the constricted iris with the concave surface facing it. The lens was grasped with the manufacturer’s holding forceps and fixed onto the posterior surface of the iris using the special enclavation needles. Results: We have operated 12 eyes in two different clinical centres successfully, with minimal intra- and/or postoperative complications. Conclusion: We believe that this is a viable solution for the visual rehabilitation of patients, who would otherwise need more than one operation for a lens exchange.

Background: The role of fluoride in preventing tooth decay both for children and adult has been acknowledged internationally. There are several types of fluoride modalities either topically or systemic way. In Indonesia the modalities used to apply are fluoride tablet, fluocol solution and fluoride containing toothpaste. The purpose of this research is to find the effectiveness of fluoride modalities.Method: The study design was quasy experimental with 40 extracted teeth (Premolar teeth). The teeth divided into four groups D group I soaked on tablet fluor, Group II ; soaked on fluocol solution, Group III soaked on fluoride tooth paste and group IV soaked on Mill J (Aquadest/ Control solution). Fluoride concentration before and after soaking was determined using Spectrophotometer UV-Vis. Fluoride absorption was determined by the reduction of fluoride concentration after soaking.Result: Research result shown that the highest fluoride absorption was on soaking in fluoride tablet, followed by soaking on fluocol and tooth paste (mean fluoride absorption was 0,32; 0,08 and 0,04 ppm). Anova test shown significance level was 0,000.Conclusion: there were a significance of fluoride absorption on soaking in tablet fluoride, fluocol solution and toothpaste. The mechanism of fluoride regimens shown different fluoride absorption.

Abstract Background The aim of this study was to evaluate the clinical outcomes of pars plana vitrectomy (PPV) combined with penetrating keratoplasty (PKP) and transscleral-sutured intraocular lens (IOL) implantation (IOL-suture) in complex eyes.Methods In this prospective, consecutive interventional case series, patients who underwent PKP combined with PPV and IOL implantation from July 2014 to March 2018 at Yokohama Minami Kyosai Hospital were enrolled. The postoperative best corrected visual acuity (BCVA) (converted to logarithm of the minimal angle of resolution [logMAR] units), intraocular pressure (IOP, mmHg), endothelial cell density (ECD, cells/mm2), graft survival, complications, astigmatism, and spherical equivalent (dioptres [D]) were evaluated. Results This study included 11 eyes of 11 patients (three females and eight males; mean age, 61.8 ± 13.9 years) with an injury (n = 6) or bullous keratopathy (n = 5). The BCVA significantly improved from 1.50 ± 0.66 logMAR preoperatively to 0.78 ± 0.59 logMAR (p < 0.001) postoperatively. The baseline ECD significantly decreased from 2396 ± 238 cells/mm2 preoperatively to 1132 ± 323 cells/mm2 (p < 0.001) postoperatively. Despite two rejection episodes, graft survival rates were 100%. The mean follow-up period was 38.0 ± 20.5 months. Two patients required combined glaucoma surgery, and three patients underwent subsequent glaucoma surgery. Postoperative astigmatism and spherical equivalent were 3.9 ± 3.2 D and 0.29 ± 2.18 D, respectively.Conclusion The combination of PKP, PPV, and IOL-suture implantation could be a safe and effective approach for eyes requiring anterior segment surgery; however, these eyes are associated with a higher incidence of glaucoma surgery.

Tunnel Syndrome

Carpal tunnel syndrome is the compression neuropathy in upper extremity. Several researches have been done to see the effect of various treatments separately. But very little research work is available for comparison of treatments. So the study was aimed to study the clinical and electrophysiological findings and their Comparision before and after various treatments. NCS was carried out in 200 CTS patients before and after 6weeks of treatment. Patients were divided into 4 groups. Group I- operative, Group II-medicinal treatment, Group III-exercise, Group IV-medicine+exercise. Clinical and electrophysiological parameters all groups were compared before and after treatment. Group (I), showed significant changes in all parameters except SNAP in operated Rt. Hand as compared to Lt. Hand. Group-II showed significant changes in DML,DML(diff.),DSL,DSL(Diff.)except CMAP,SNAP,&SCV in Rt. Hand but in Lt. hand DML,DML(diff.)DSL showed significant changes where as DSL(Diff.) CMAP,SNAP,&SCV were non-significant. Group-III showed significant changes in DML, DML(diff.),DSL,DSL(Diff.) but SCV,SNAP and CMAP were non-significant in Rt. hand but in Lt. hand only DML(diff.) was significant . Group-IV showed significant changes in all parameters except SCV in Rt. hand but in Lt. hand DML, DML (diff.),DSL, DSL(Diff.) were significant , where as SNAP, CMAP, and SCV were non-significant. It was concluded that maximum improvement was observed in clinical and electrophysiological parameters in operative group, then Medicine + exercise Group, then exercise Group and minimum in Medicinal treatment Group. So operative method is the method of choice for CTS; however the duration of treatment should be more so that further improvements can be seen in all parameters.

Abstract Background: The incidence of nucleus drop or intraocular lens (IOL) drop as the complication of phacoemulsification increases due to the increased frequency of phacoemulsification. Pars plana vitrectomy (PPV) followed by endofragmentation and secondary IOL implantation is the choice of procedure for management. This study aims to determine the frequency, outcomes, and complication of PPV in the case of nucleus drop or IOL drop in the Department of Ophthalmology, Fakultas Kedokteran Universitas Indonesia – Rumah Sakit Cipto Mangunkusumo (FKUI-RSCM) Methods: This study is a retrospective descriptive study conducted in the Vitreoretinal Division of the Department of Ophthalmology, FKUI - RSCM. Research data was taken from the medical records of all nucleus drop or IOL drop patients underwent PPV in January 2017-December 2017. Results: There were 19 cases studied. The incidence of nucleus drop occurred in phacoemulsification surgery techniques (94.7%) and ECCE techniques (5.3%). Vitrectomy surgery was performed ≤2 weeks in 31.6% and >2 weeks in 68.4% after the patient first arrived at the vitreoretinal clinic. Most pre-PPV visual acuity was 1/60-6/60 (47.1%). In the final follow-up, visual acuity improved from 6/45 to 6/6 occurred in 42.2% of cases. Complication after PPV and secondary IOL implantation include elevated IOP (10.5%), IOL decentration (5.3%), corneal decompensation (5.3%), macular edema (5.3%), and retinal detachment (5.3%). Conclusion: Nucleus drop or IOL drop generally occurs in phacoemulsification cataract surgery techniques. Improved visual acuity was achieved after PPV and secondary IOL implantation at the end of the follow-up period. Most common post-PPV complication is elevated IOP.

Purpose. To describe and explore an alternative approach for sulcus intraocular lens (IOL) implantation in the absence of capsular support.Methods. The commonly available one-piece poly(methyl methacrylate) (PMMA) lens is stabilized in the sulcus by two intraocular horizontal strings of 10/0 polypropylene suture passed through the lens dialing holes in opposite directions to achieve a mechanical balance. The horizontal strings of 10/0 polypropylene work as a rail track for the IOL optics, allowing some side to side lens adjustment even following wound closure. The stability of the IOL was tested in vitro. Six aphakic patients underwent in-sulcus IOL secondary implantation using the balanced two-string technique. Patients were followed up for a minimum of six months. Best spectacle corrected vision was assessed. Lens centration and lens tilt were measured by anterior segment optical coherence tomography (AS-OCT).Results. All patients had successful lens insertion. Best spectacle corrected visual acuity (BSCVA) improved in all patients. Lens decentration ranged between 0.21 mm and 0.9 mm (average 0.53 mm). Lens tilt ranged between 1.2° and 2.8° (average 2.17°).Conclusion. The mechanically balanced two-string technique is an alternative option for sulcus IOL implantation in absence of capsular support, allowing lens centration adjustment with no additional risks.
