Öğe Clinical results of implantation of the Medevec® mini-loop haptic anchor plate foldable lenses(Springer Netherlands, 1998) Kaskaloglu M.; Erakgun T.Purpose: To evaluate the surgical performance and postoperative outcomes of 50 consecutive implantations of the Medevec VS 2 UV(TM) mini-loop silicone plate lenses. Setting: Ege University Hospital, Eye Department, Izmir, Turkey. Methods: Forty-three patients of either sex, aged 49 years, or older, were included in the study. Clear corneal incision, circular curvilinear capsulorhexis, phacoemulsification and implantation of the Medevec VS 2 UV(TM) mini-loop silicone plate lenses using the injector-cartridge system was performed in all cases. The mean outcome measures were ease of implantation, intraoperative and postoperative complications, postoperative centration and visual acuity. Results: The mean follow-up was 10.2 months (range 8-11 months). Twenty-two lenses (44 required two or more manoeuvers. In 6 cases, the lens was implanted into a bag with torn anterior capsule and in 3 patients (6 implanted into the sulcus because of a torn posterior capsule during phacoemulsification. Best corrected visual acuity was ? 7/10 in 48 eyes (96%) and ? 10/10 in 42 eyes (84%) at 8 months. The examination of the lenses after 8 months showed no sign of haze, discoloration or tilt. Mean decentration of the lenses was 0.32 mm ± 0.19 (SD). There were no cases of cystoid macular edema or retinal detachment. YAG capsulatomy was performed in one eye. Conclusions: Medevec VS 2 UV(TM) mini-loop silicone plate lenses appeared to have some learning curve for the implantation. They provided - even in the sulcus - excellent centration, good visual acuity and minimal postoperative complications.Öğe Conventional buckling surgery or primary vitrectomy with silicone oil tamponade in rhegmatogenous retinal detachment with multiple breaks(2004) Afrashi F.; Erakgun T.; Akkin C.; Kaskaloglu M.; Mentes J.Background: There is controversy about the most appropriate operating methods for complicated rhegmatogenous retinal detachment (RD) including multiple tears, and surgical techniques may be changed according to the preference of the surgeon. In this retrospective study, we compared the surgical results of conventional buckling surgery and vitrectomy with silicone oil tamponade for rhegmatogenous (RD) with multiple breaks. Methods: Thirty patients who underwent scleral buckling surgery (group 1) and 22 patients who underwent pars plana vitrectomy with silicone oil tamponade (group 2) as the primary surgery for rhegmatogenous RD with multiple breaks were included in this study. The follow-up period was longer than 6 months after surgery. The anatomical success rates and complications were evaluated for both groups. Results: Retinal reattachment was achieved in 24 of 30 eyes (80%) in group 1 and in 20 of 22 eyes (90.9%) in group 2 after the initial surgery. In group 1, subretinal hemorrhage developed due to the drainage of subretinal fluid in 2 eyes (6.6%) intraoperatively. Elevated intraocular pressure (3.3%), ocular motility disturbances (13.2%), and proliferative vitreoretinopathy (3.3%) were seen in the postoperative period. In group 2, iatrogenic breaks (7.3%) and lens damage (9.09%) occurred during the operation. Macular pucker (4.5%), postoperative cataract progression (22.7%), ocular hypertension (9.09%) and PVR (9.09%) were noted postoperatively. Conclusions: Both surgical procedures can achieve favorable and comparable anatomic outcomes in the majority of patients in the treatment of RD with multiple breaks. Intra-and postoperative complications are different in the two procedures. © Springer-Verlag 2004.Öğe Dense opacification of the optical component of a hydrophilic acrylic intraocular lens: A clinicopathological analysis of 9 explanted lenses(2001) Werner L.; Apple D.J.; Kaskaloglu M.; Pandey S.K.Purpose: To report clinical, pathological, histochemical, ultrastructural, and spectrographic analyses of explanted hydrophilic acrylic intraocular lenses (IOLs) obtained from patients who had visual disturbances caused by postoperative opacification of the lens optic. Setting: Center for Research on Ocular Therapeutics and Biodevices, Storm Eye Institute, Medical University of South Carolina, Charleston, South Carolina, USA, and Ege University, Alsancak Izmir, Turkey. Methods: Nine hydrophilic IOLs (SC60B-OUV, MDR Inc.) were explanted from 9 patients with decreased visual acuity. Most patients became symptomatic approximately 24 months after uneventful phacoemulsification and IOL implantation. Opacification was noted and appeared clinically to be associated with a fine granularity within the substance of the IOL optic. The IOLs were forwarded to the center and examined by gross and light microscopy. Full-thickness cut sections of the optics were stained with 1% alizarin red and the von Kossa method (special stains for calcium). Some were submitted for scanning electron microscopy and energy dispersive x-ray spectroscopy. Results: Microscopic analyses revealed multiple fine, granular deposits of variable sizes within the lens optics, usually distributed in a line parallel to the anterior and posterior curvatures of the optic, with a clear zone just beneath the optic surface. The deposits stained positive with alizarin red and the von Kossa method. Energy dispersive x-ray spectroscopy of the internal substance of sectioned IOLs demonstrated the presence of calcium within the deposits. Conclusion: This is the first clinicopathological report of optic opacification occurring with this hydrophilic acrylic IOL model. Studies of similar cases with this lens should be done to determine the incidence and possible mechanisms of the phenomenon. © 2001 ASCRS and ESCRS.Öğe Öğe Hydrophilic acrylic intraocular lens optic and haptics opacification in a diabetic patient: Bilateral case report and clinicopathologic correlation(2002) Pandey S.K.; Werner L.; Apple D.J.; Kaskaloglu M.Objective: To report clinicopathologic and ultrastructural features of two opacified single-piece hydrophilic acrylic intraocular lenses (IOLs) explanted from a diabetic patient. Design: Interventional case report with clinicopathologic correlation. Setting: A 64-year-old white female underwent phacoemulsification and implantation of a single-piece hydrophilic acrylic lens (SC60B-OUV; Medical Developmental Research, Inc., Clear Water, FL) in October 1998 in the left eye and in July 1999 in the right eye. The best-corrected visual acuity after surgery was 20/60 in the left eye and 20/50 in the right eye. The patient had a marked decrease in visual acuity in June 2000 as a result of a milky, white opalescence of both lenses. Intraocular lens explantation and exchange was performed in both eyes and the explanted IOLs were submitted to our center for detailed pathologic, histochemical, and ultrastructural evaluation. They were stained with alizarin red and the von Kossa method for calcium, and also underwent scanning electron microscopy and energy dispersive radiograph spectroscopy to ascertain the nature of the deposits leading to opacification. Main Outcome Measures: Documentation of calcium deposits confirmed by histochemical stains and surface analyses. Results: Opacification of the IOL was found to be the cause of decreased visual acuity. The opacification involved both the IOL optic and the haptics in the left eye and was confined to the IOL optic in the right eye. Histochemical and ultrastructural analyses revealed that the opacity was caused by deposition of calcium and phosphate within the lens optic and haptics. Conclusions: There are two features that distinguish this case from those reported earlier. This is the first clinicopathologic report of lens opacification that has involved completely the lens optic and the haptics. Second, these two explanted IOLs document the first bilateral case. This process of intraoptic and haptic opacification represents dystrophic calcification of unknown cause. Diabetic patients appear to be more severely and more often affected by lens opacification. Long-term follow-up of diabetic patients implanted with this IOL design should be maintained by surgeons and manufacturers. © 2002 by the American Academy of Ophthalmology, Inc.Öğe Postoperative opacification of the peripheral optic region and haptics of a hydrophilic acrylic intraocular lens: Case report and clinicopathologic correlation(2006) Kleinmann G.; Werner L.; Kaskaloglu M.; Pandey S.K.; Neuhann I.M.; Mamalis N.We report the first case of opacification of the BioComFold 92S (Morcher GmbH) intraocular lens. The opacification pattern is unique, presenting mainly in the periphery of the optic and the haptics of the lens, leaving the central portion of the optic clear. The clinical course of this opacification pattern is not observed typically with other hydrophilic acrylic lens designs and requires further study. © 2006 ASCRS and ESCRS.Öğe A simple 'lasso' for intraocular foreign bodies(1999) Erakgün T.; Ates H.; Akkin C.; Kaskaloglu M.Three patients had foreign bodies in their anterior chambers following penetrating ocular injuries. These foreign bodies were removed by a closed chamber technique using a simple loop. The loop was created by a 22-gauge intravenous cannula and a 7-0 polypropylene suture. Retained cilia in one patient and metallic foreign bodies in two patients were removed using this intraocular 'lasso.' Sutures were not placed at the incision sites at the end of the surgery. This is an inexpensive and easy to prepare technique that introduces minimal surgical trauma. In addition, two hands are not needed for loop manipulation. This technique may be an excellent alternative for removal of small intraocular foreign bodies.Öğe Therapeutic effect of intracameral streptokinase injection in eyes with pseudophakic fibrinoid reaction [INTRAKAMERAL STREPTOKINAZ ENJEKSIYONUNUN PSODAFAKIK FIBRINOID MEMBRANLI GOZDEKI TERAPOTIK ETKISI](1994) Akkin C.; Mentes J.; Kaskaloglu M.; Erbakan G.; Kose S.Intracameral 1000 IU purified streptokinase was injected into the eyes with pseudophakic fibrinoid pupillary membrane, occurred in 8 eyes of 8 patients after cataract operation. Three of them had been operated for traumatic cataract, one for congenital cataract, one for complicated cataract, and the others for senile cataract with concurrent pathologic conditions like diabetes mellitus and glaucoma. In 7 eyes (%87.5), pupillary fibrinoid membrane disappeared in a period ranging from one hour to 5 days. The visual acuity improved in all patients, and increased from mean 0.06 to mean 0.3 after the injection. None of the eyes developed hyphema or corneal edema during follow-up time of mean 4.3 months. We concluded that intracameral streptokinase injection is an effective treatment modality of pseudophakic fibrinoid pupillary membrane.
