Purpose: Optical properties of commonly used multifocal and extended-depth-of-focus (EDOF) intraocular lenses (IOLs) can induce artifacts or changes in optical coherence tomography (OCT) measurements. Our purpose was to investigate the possible effects of different IOLs on peripapillary and macular OCT parameters.
Methods: The preoperative and postoperative third-month peripapillary OCT and ganglion cell analysis (GCA) parameters of patients having monofocal (Alcon IQ), multifocal (PanOptix), or EDOF (Vivity) IOL implanted during cataract surgery were compared.
Purpose: To compare the severity and duration of ocular discomfort after three different epithelial debridement techniques for corneal collagen cross-linking in the treatment of keratoconus.
Methods: Fifty-five patients (65 eyes) known to have keratoconus were enrolled in this retrospective study. The eyes were divided into three groups based on the technique used for epithelial debridement for corneal collagen cross-linking procedure; excimer laser transepithelial phototherapeutic keratectomy was used in group 1 (18 eyes), alcohol-assisted epithelial removal was used in group 2 (27 eyes), and mechanical epithelial debridement was used in group 3 (20 eyes).
Purpose: To determine the galectin-3 (Gal3), interleukin-1 (IL-1), interleukin-6 (IL-6), and epidermal growth factor (EGF) levels in corneal epithelium of patients with recurrent corneal erosion (RCE) syndrome and compare them with healthy controls.
Methods: In this prospective interventional case control study, 32 eyes of 32 patients with RCE syndrome who had corneal epithelial erosions and 28 eyes of 28 healthy participants scheduled for photorefractive keratectomy (control group) were included. Exclusion criteria included corneal dystrophies, ectasia, dry eye, previous ocular surgery or topical medications, and systemic diseases.
Descemet Membrane Endothelial Keratoplasty: Outcomes in the First Year of Experience.
Exp Clin Transplant
March 2018
Objectives: We aimed to report the clinical outcomes of Descemet membrane endothelial keratoplasty in our first year of experience.
Materials And Methods: Patients who underwent Descemet membrane endothelial keratoplasty at the Baskent University Faculty of Medicine, Department of Ophthalmology, between 2015 and 2016 were included in the study. Patient demographics, cause of endothelial dysfunction, best-corrected visual acuity, central corneal thickness, graft survival, follow-up duration, and intraoperative and postoperative complications were recorded.
Purpose: To evaluate the elastic modulus, hardness, and mechanical properties of the anterior lens capsule in different types of cataract and to assess the correlation with age.
Setting: Baskent University Hospital, Department of Ophthalmology, Ankara, Turkey.
Design: Prospective comparative study.
Objective: To evaluate the effect of dry eye on Scheimpflug imaging of the cornea and elevation data.
Design: Prospective observational study.
Participants: Scheimpflug images of 50 patients with dry eye who were being tested for eligibility for corneal refractive surgery were screened.
Objectives: Here, our aim was to report our treatment strategies and their results performed for visual rehabilitation after penetrating keratoplasty.
Materials And Methods: The medical records of 98 patients (54 male/44 female), with results from 104 eyes, who underwent penetrating keratoplasty between January 2013 and January 2015 at the Baskent University Faculty of Medicine, Department of Ophthalmology were reviewed. Patient age, indication for penetrating keratoplasty, interventions performed for visual rehabilitation, follow-up duration, topographic and refractive astigmatism at the end of follow-up, and final best corrected visual acuity results were recorded.
Clinical outcomes of scleral Misa lenses for visual rehabilitation in patients with pellucid marginal degeneration.
Cont Lens Anterior Eye
December 2016
Article Synopsis
- The study investigates the effectiveness of scleral Misa lenses for visual rehabilitation in patients with pellucid marginal degeneration (PMD), involving 24 eyes of 12 patients.
- Results showed a significant improvement in best-corrected visual acuity, with patients experiencing an average gain of 3.3 lines after using the lenses, and a majority (67%) wore the lenses for over 8 hours daily.
- The findings suggest scleral lenses are beneficial for PMD patients who cannot tolerate other types of lenses, particularly those with lower initial visual acuity who see the most improvement.
A silicone hydrogel contact lens after 7 years of continuous wear.
Cont Lens Anterior Eye
August 2013
Purpose: To report an unusual case with a bandage silicone hydrogel lens that was applied over cyanoacrylate glue application for corneal perforation.
Design: Retrospective, interventional case report.
Methods: A 67-year-old woman with a history of corneal trauma experienced spontaneous corneal perforation in her left eye.
Severe corneal changes following intravitreal injection of bevacizumab.
Ocul Immunol Inflamm
August 2010
Purpose: To report a series of severe corneal changes following intravitreal injection of bevacizumab (Avastin) for age-related macular degeneration.
Design: Retrospective noncomparative case series.
Methods: The authors retrospectively reviewed the corneal changes that developed after the procedure in 1200 (460 patients) intravitreal injections of bevacizumab.
Purpose: To evaluate the ocular surface changes and tear-film functions in patients treated with systemic isotretinoin.
Methods: Fifty subjects treated with 0.8 mg/kg oral isotretinoin were enrolled in this prospective clinical trial.
Article Synopsis
- The study aimed to compare the clinical outcomes of conjunctival autograft versus amniotic membrane transplantation (AMT) for pterygium surgery to assess cosmetic results.
- In a randomized study involving 78 patients, results showed no significant difference in recurrence rates between the two techniques, but conjunctival autografting had better final cosmetic appearances.
- While conjunctival autografting was more effective for appearance, AMT remains a viable option for patients with limited conjunctival tissue.
Purpose: To evaluate the ocular surface changes in a rabbit dry eye model by using a modified impression cytology technique.
Methods: Nitrocellulose filter paper with a pore diameter of 0.45 microm was used to collect the specimens from 12 rabbits that were injected with atropine every day for 3 days.
Article Synopsis
- The study investigates graft vascularization using indocyanine green angiography after pterygium surgery with two types of grafts: limbal-conjunctival autograft transplantation (LCAT) and amniotic membrane transplantation (AMT).
- After evaluating anterior segment ICGA findings at multiple time points, results showed early vascularization in LCAT grafts by day 7, while AMT grafts exhibited no vascularization throughout the studied period.
- The findings suggest that LCAT provides better early graft health, while AMT may experience delayed vascularization, possibly affecting graft perfusion and recurrence of pterygium, indicating a need for further research.
Purpose: To evaluate the effects of smoking on ocular surface.
Design: Prospective, comparative, interventional case series.
Methods: setting: Institutional.
