PURPOSE: To compare the aqueous oxidative stress, prostaglandin E2 (PGE2 ), and cytokine levels after low-energy femtosecond laser-assisted cataract surgery versus conventional phacoemulsification, and to evaluate the effect of a nonsteroidal antiinflammatory drug (NSAID) on the aqueous profiles. SETTING: Singapore National Eye Center, Singapore. DESIGN: Randomized controlled trial. METHODS: Thirty-five patients were randomized to receive conventional phacoemulsification in one eye and femtosecond laser-assisted cataract surgery in the fellow eye...

New optical technologies enhancing localization or assessing viability of parathyroid glands (PG) during endocrine surgery have been reported in clinical studies. These technologies could become complementary to the surgeon's eyes and may improve surgical outcomes in thyroidectomy and parathyroidectomy. Here, we conducted a systematic review focusing on PG identification and functional assessment using optical methods to enhance surgery. A systematic literature review was performed using MEDLINE and Embase database...

Introduction: Laser in situ keratomileusis (LASIK), a refractive surgery procedure is being performed in a large number among people with refractive errors. In all the people undergoing the procedure, there is a potential risk to misdiagnose the glaucoma disease due to changes in central corneal thickness (CCT). In subjects who have undergone laser refractive interventions, intraocular tension may be lower and underestimated, and this can lead to later detection of glaucoma. Aim: The objective of this study was to analyze the intraocular pressure (IOP) after LASIK in patients with myopia...

The purpose of this study was to present the surgical outcome in optic disc pit associated maculopathy in a patient who was treated with vitrectomy, internal limiting membrane (ILM) peeling, barrage laser photocoagulation, and silicone oil tamponade. A 21-year-old Indian male was diagnosed with optic disc pit maculopathy in his left eye with a best-corrected visual acuity (BCVA) of 20/200. A 23-gauge pars plana vitrectomy with peeling of ILM was done using brilliant blue dye. After completion of vitrectomy, fluid-air exchange was performed and silicone oil was instilled into eye...

The article reviews the particularities of development and pathogenesis of secondary dry eye syndrome (DES) after refractive surgeries including a complex of problems related to changes in tear film content, damage of eye surface and neurotrophic epitheliopathy. Additionally, modern algorithms of treatment and prevention of secondary DES in patients after refractive surgeries are described. Despite the transient nature of the changes, excimer-laser surgery can lead to lasting deficiencies of eye surface in some patients...

Nd:YAG laser vitreolysis has been used as a noninvasive approach to treat visually significant vitreous strands and floaters. However, severe vision-threatening complications may occur. The authors describe a rare case of a 60-year-old woman who had suffered rupture of the posterior lens capsule with subsequent cataract formation 1 week post-Nd:YAG laser vitreolysis in the right eye. The authors performed phacoemulsification, pars plana vitrectomy, and intraocular lens implantation at the ciliary sulcus. At 1 month post-surgery, the patient's visual acuity had not recovered well and optical coherence tomography showed epiretinal membrane (ERM) formation...

The authors present the first case of macular hole (MH) after a single inhalation of poppers. A 13-year-old girl presented with vision loss in the left eye (OS). Pediatric and neurology exams were normal. Funduscopy revealed bilateral papilledema and yellow foveal spot OS. Optic neuritis was diagnosed and treated. Due to foveal alteration, optical coherence tomography was performed, and MH was diagnosed. Twenty-three-gauge pars plana vitrectomy, peeling of the internal limiting membrane, and SF6 exchange were performed...

BACKGROUND AND OBJECTIVE: To compare the surgical outcomes of epiretinal membrane (ERM) treatment between eyes with and without an ectopic inner foveal layer (EIFL). PATIENTS AND METHODS: Seventy-seven ERM eyes of 76 consecutive patients were investigated retrospectively. Optical coherence tomography examinations and best-corrected visual acuity (BCVA) measurements were performed before and at 6 and 12 months after vitrectomy. RESULTS: In both eyes with and without an EIFL, the BCVAs at 6 and 12 months after vitrectomy were significantly better than those before vitrectomy (P < ...

AIM: Femtosecond laser assisted cataract surgery is associated with pupillary constriction. This study aims to look at patient and surgical factors predisposing to abnormal pupil behaviour during FLACS. METHODS: This prospective observational study included all patients undergoing FLACS in the Princess of Wales Hospital, Bridgend, UK between February and June 2017. Pupils were measured at three time points; immediately before and after laser pre-treatment, and at the start of surgery...

PURPOSE: To systematically compare the efficacy, predictability, safety, postoperative haze, pain scores, and epithelial healing time of four corneal surface ablation procedures. METHODS: PubMed, Embase, Cochrane Library, and the U.S. trial registry were searched up to June 2018. Randomized controlled trials were selected. Efficacy (uncorrected distance visual acuity of 20/20 or better), predictability (refractive spherical equivalent within ±0.50 diopters [D] of the target), and safety (loss of two or more lines of spectacle corrected distance visual acuity) were set as primary outcome measures...

Purpose: To evaluate the visual, refractive, and topographic outcomes after simultaneous topography-guided transepithelial photorefractive keratectomy (transepithelial TG-PRK) using the Amaris Excimer laser platform and accelerated corneal cross-linking (CXL) in eyes with keratoconus. Materials and Methods: Patients with 2 years of follow-up were included in this retrospective case series. Manifest refraction (MR), uncorrected (UDVA) and corrected (CDVA) distance visual acuity, corneal topography, and pachymetry were evaluated at 1, 3, 6, 12, and 24 months after surgery...
