BACKGROUND AND OBJECTIVE: Effects of repeat surgery in failed primary full-thickness macular hole (FTMH) closure with the inverted internal limiting membrane (ILM) flap technique. PATIENTS AND METHODS: Retrospective analysis of patients operated with the inverted ILM flap technique. Optical coherence tomography was performed before initial and secondary surgeries and then at up to 12 months post-surgery. RESULTS: During the second surgery, the inverted ILM flap created at the first attempt had returned to its original position, instead of covering the FTMH...

BACKGROUND AND OBJECTIVE: To investigate changes in the pattern of metamorphopsia in patients after idiopathic macular hole (MH) surgery and the relationship between metamorphopsia, visual acuity (VA), and macular parameters. PATIENTS AND METHODS: This prospective, interventional study included 53 eyes of 53 patients with idiopathic full-thickness MH. The severity of metamorphopsia was quantified using M-CHARTs. Minimal and basal diameter of MH and disrupted length of ellipsoid zone were measured using spectral-domain optical coherence tomography...

BACKGROUND AND OBJECTIVE: To investigate the predictive factors of visual acuity (VA) after cataract surgery in patients with retinitis pigmentosa (RP). PATIENTS AND METHODS: Retrospective, observational study. The authors reviewed a consecutive series of 70 patients (109 eyes) with RP who underwent cataract surgery. The changes in best-corrected visual acuity (BCVA) before and 3 months after surgery were measured. The relationship between preoperative ellipsoid zone (EZ) conditions, external limiting membrane (ELM) conditions, central macular thickness (CMT), and postoperative BCVA were investigated...

BACKGROUND AND OBJECTIVE: To report anatomical and functional outcomes of surgery in each of the eyes in cases of bilateral macular hole (MH). PATIENTS AND METHODS: The anatomical and functional results for 42 patients with bilateral idiopathic MH were evaluated retrospectively. First-operated and fellow eyes were compared at various time points for preoperative characteristics and postoperative outcomes. RESULTS: Anatomical success was achieved in all patients after a single operation, and no reopening of an initially closed MH was observed during the follow-up period...

BACKGTOUND: Photorefractive keratectomy (PRK) is used for a wide range of refractive errors such as low to moderate myopia, hyperopia and astigmatism. While many improvements have been made in laser application and accuracy as well as the modes of corneal flap removal, and although the results are somewhat predictable, regression of refractive errors is still a common complaint among the patients undergoing refractive surgery with Excimer Laser. We aimed to determine related factors of regression following photorefractive keratectomy (PRK) in different types of refractive errors...

Methods: A cross-sectional study in type 2 diabetic patients was conducted in a community of Fushun between July 2012 and May 2013. Questionnaire, detailed ophthalmic examination and laboratory tests were completed to collect the information about sociodemographic and healthcare characteristics...

PURPOSE: To report a central retinal artery occlusion with cilioretinal artery sparing in a 48-year-old woman after laser-assisted in situ keratomileusis surgery. METHODS: Case history and clinical examination including best-corrected visual acuity, serum markers, slit-lamp biomicroscopy, indirect ophthalmoscopy, fundus photography, fluorescein angiography, and optical coherence tomography. RESULTS: A 48-year-old woman underwent routine laser-assisted in situ keratomileusis surgery in both eyes...

PURPOSE: Presentation of a case with ocular hypertension who developed cystoid macular edema (CME) following selective laser trabeculoplasty (SLT). CASE REPORT: A 62-year-old male patient who had undergone phacoemulsification surgery for traumatic cataract 9 years ago was on ocular hypertension treatment for the last 5 years. Due to uncontrolled intraocular pressure and side effect of medications, a 360° SLT was performed. The patient returned with decrased visual acuity 1 week after the procedure...

Patients who have had previous refractive procedures often require cataract surgery at an early age; however, postoperative results are compromised by corneal aberrations and difficulties achieving a desired refractive endpoint. We describe the use of the IC-8 small-aperture intraocular lens (IOL) in 3 patients who had previous laser in situ keratomileusis (LASIK). Standard cataract surgery was performed in all cases. The small-aperture IOL was implanted in the patient's nondominant eye, and a clear aspheric monofocal IOL was implanted in the dominant eye...

Purpose: To describe a case of interface fluid formation caused by uncontrollable intraocular pressure (IOP) 16 years after laser-assisted in situ keratomileusis (LASIK) surgery secondary to Posner Schlossman Syndrome (PSS). Observations: After trabeculectomy operation, IOP of the operative eye was back to normal, and the interface fluid refluxed over time. Conclusions: and importance: Interface Fluid Syndrome can be a potential lifelong complication after LASIK surgery...
