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.
Application of topical 2% cyclosporine A in inflammatory ocular surface diseases.
Int Ophthalmol
November 2023
Purpose: To report our experience with the 2% cyclosporin A (CsA) in a series of challenging inflammatory ocular surface diseases due to different etiologies.
Methods: The records of patients who received topical 2% CsA for different indications were reviewed retrospectively. Demographic characteristics, indications for treatment, patient symptoms and clinical findings were recorded.
Purpose: To compare visual performance and quality of life (QoL) following bilateral implantation of a new nondiffractive extended depth-of-focus (EDOF) intraocular lens (IOL) and a trifocal IOL.
Setting: Department of Ophthalmology, Baskent University Faculty of Medicine, Ankara, Turkey.
Design: Prospective comparative interventional case series.
Impact of the COVID-19 Pandemic on Corneal Transplantation and Cornea Procurement.
Exp Clin Transplant
August 2022
Objectives: In this study, we aimed to analyze the effects of the COVID-19 pandemic in its first year on corneal transplant outcomes performed at a tertiary eye care center in Turkey.
Materials And Methods: Clinical records of patients who underwent corneal transplant between March 2020 and February 2021 (group A) at the Baskent University Faculty of Medicine, Department of Ophthalmology, were analyzed retrospectively. Patient demographics, indications for transplant, type of transplant procedure (lamellar vs penetrating), follow-up duration, and postoperative complications were recorded.
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).
Clinical Relevance: Effective treatment of corneal epithelial defects is crucial to prevent secondary infectious keratitis and visual impairment due to loss of corneal transparency. Therefore, it is important to determine the effect of different topical agents on corneal wound healing response.
Background: The aim was to compare the effects of three different eye drops on corneal epithelial wound healing in an experimental model.
Purpose: To assess agreement of a swept source-optical coherence tomography (SS-OCT) based Biometer with a standard IOLMaster device and Scheimpflug Imaging (SI) to acquire keratometric measurements in cataract patients.
Methods: In this prospective comparative study, 101 eyes of 101 cataract surgery candidates, aged 24-81 years, were sequentially examined using three devices. Keratometry values at the flat (K1) and steep (K2) axis, mean corneal power (Km) and magnitude of corneal astigmatism as well as J0 and J45 vectoral components of astigmatism obtained with the SS-OCT based biometer (IOLMaster 700) were compared with those obtained with the IOLMaster 500 and SI.
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.
Purpose: To investigate the effects of human breast milk on corneal epithelial wound healing.
Methods: The effects of human breast milk on epithelial healing is compared with autologous serum and artificial tears on 24 female Bal-b/C mice. A central corneal epithelial defect was created using a 2 mm trephine.
Clinical outcomes of scleral Misa lenses for visual rehabilitation in patients with pellucid marginal degeneration.
Cont Lens Anterior Eye
December 2016
Purpose: To report the clinical outcomes of scleral Misa lenses (Microlens Contactlens Technolgy, Arnhem, Netherlands) for visual rehabilitation in patients with pellucid marginal degeneration (PMD).
Mehods: In this prospective interventional case series, 24 eyes of 12 PMD patients were fitted with scleral Misa lenses. Patients were followed regularly for continuous daily wearing time (CDWT), contact lens handling issues, visual acuity, and any subjective or objective contact lens related complications.
Topical Bevacizumab for the Treatment of Ocular Surface Squamous Neoplasia.
J Ocul Pharmacol Ther
October 2015
Purpose: To determine the efficacy and safety of topical bevacizumab treatment in patients with ocular surface squamous neoplasia (OSSN).
Methods: Six eyes of 6 patients with primary OSSN confirmed by impression cytology received topical 5 mg/mL bevacizumab 4 times daily for a period of 8 weeks. Patients were evaluated in 2-week intervals.
Purpose: To compare the clinical results of conjunctival autograft and amniotic membrane transplantation (AMT) for primary and recurrent pterygium excision. In an effort to determine whether AMT yields acceptable cosmetic results as conjunctival autografting in pterygium surgery, we compared the final cosmetic outcomes of these 2 techniques.
Methods: We performed a prospective, randomized clinical study of 78 eyes (78 patients) divided into 2 groups.
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.
Purpose: To monitor the development of graft vascularization by indocyanine green angiography (ICGA) after pterygium excision with limbal-conjunctival autograft transplantation (LCAT) and amniotic membrane transplantation (AMT).
Design: Randomized prospective interventional case series.
Methods: Anterior segment ICGA findings at one, seven, and 30 days after surgery were evaluated in eyes with primary pterygium treated by excision and LCAT (14 eyes of 14 patients) or AMT (13 eyes of 13 patients), and the results for graft vascularization were compared.
Purpose: To evaluate the effects of smoking on ocular surface.
Design: Prospective, comparative, interventional case series.
Methods: setting: Institutional.
