Purpose: To evaluate the changes in corneal biomechanical properties and tear film layer analysis after upper eyelid blepharoplasty surgery.
Method: Sixty eyes of 30 patients were included in our prospective study. Corneal hysteresis (CH), corneal resistance factor (CRF), corneal compensated intraocular pressure (IOPcc) and Goldmann intraocular pressure (IOPg) measurements were taken with the Ocular Response Analyzer (ORA) device at the preoperative, postoperative 1st and 3rd months.
Purpose: The current study is aimed to present the long-term results of the patients who underwent conjunctivolimbal autograft (CLAU) as the primary operation in unilateral limbal stem cell deficiency and the ocular surface safety of the donor eyes. The patients were followed up for five years or longer.
Methods: The records of all patients who underwent CLAU as the primary operation were retrospectively analyzed.
Purpose: We aimed to investigate the efficacy and safety of single-dose autologous serum eye drops (ASEDs) for treatment of persistent corneal epithelial defects (PEDs).
Methods: About 34 eyes of 26 patients treated from March 2016 to May 2020 with a single dose of ASEDs for PEDs that did not respond to conventional treatment were retrospectively evaluated. Patient demographics, predisposing factors, size, and duration of the PED, duration of treatment, and dosage of ASEDs, PED healing time, success rate of the ASED treatment, and follow-up time after the onset of ASED treatment were recorded.
Article Synopsis
- The study aims to evaluate the use of donor corneal grafts for repairing scleral surface problems in patients whose corneal tissues were not suitable for traditional keratoplasty or were leftover from such surgeries.
- Retrospective analysis of 16 patients showed various indications for corneal grafts, including trauma, glaucoma surgeries, and implant erosions, with a mean follow-up of 14 months and no reported complications.
- The results indicate that using these donor grafts effectively restores the ocular surface and improves cosmetic appearance in patients with scleral tissue loss, prompting further investigation into their long-term efficacy and safety.

February 2021
Objectives: To compare our combined surgery (CS) and sequential surgery (SS) results.
Materials And Methods: The files of 44 patients who underwent CS (penetrating keratoplasty [PK], cataract extraction, and intraocular lens [IOL] implantation) and 126 patients who underwent SS (cataract extraction and IOL implantation in a second session after PK) between January 2009 and December 2018 were evaluated retrospectively. One eye of the patients who were followed up for at least 1 year was included in the study.
Purpose: To evaluate the efficacy of topical fresh frozen plasma (FFP) therapy on clinical symptoms, findings, and prognosis after anterior segment surgeries in patients with ligneous conjunctivitis (LC).
Methods: Retrospective case note review.
Results: Eleven eyes of 7 cases whose remission was not achieved after medical treatment such as topical corticosteroids, cyclosporine A, and heparin were included in the study.
Purpose: To evaluate anterior segment findings in Behçet's disease patients within the ocular involvement inactive period.
Methods: One hundred twenty patients with Behçet uveitis in the inactive period (Behçet's disease group) and 121-age and sex matched healthy subjects (control group) were examined. Anterior segment parameters were assessed by Scheimpflug camera.
Purpose: To determine the indications, frequency, influential factors and clinical outcomes of resuturing in an atraumatic setting after penetrating keratoplasty (PK).
Methods: Medical records of all patients who underwent resuturing in the absence of traumatic wound dehiscences after PK between January 1, 2007 and December 31, 2015 were reviewed. The cases were divided into 2 groups: patients with suture-related problems underwent mandatory resuturing (mandatory group), and patients with post-PK ectasia or a progressive increase in K values and surgically induced astigmatism underwent optional resuturing (Optional group).
Purpose: To evaluate the efficacy and safety of corneal collagen cross-linking with photoactivated chromophore (PACK-CXL) plus medical treatment in comparison with the non-CXL group in the management of graft infections after penetrating keratoplasty.
Methods: Forty eyes of 40 patients, 18 eyes in the PACK-CXL group and 22 eyes in the non-CXL group, with graft infections were retrospectively reviewed. Patients with microbial keratitis who were resistant to medical treatment for at least 1 week were treated with PACK-CXL in conjunction with medical treatment.
Background: The purpose of this study was to investigate factors affecting wound dehiscence due to blunt trauma following penetrating keratoplasty (PK) and the clinical outcomes.
Methods: The medical records of patients who experienced blunt traumatic wound dehiscence after PK between 1995 and 2015 were analyzed retrospectively. The incidence and etiology of the trauma, the time interval between PK and globe rupture, final graft clarity, best-corrected visual acuity, complications, secondary surgeries, and factors potentially affecting wound dehiscence size were recorded.
Infectious keratitis after corneal lamellar surgery is a rare complication. In this report, we present unexpected complications after crescentic lamellar wedge resection (CLWR) and their treatment in a patient with pellucid marginal degeneration. A 42-year-old male patient developed fungal keratitis due to in the late postoperative period after CLWR.

Materials And Methods: We retrospectively evaluated 200 eyes and 200 consecutive patients who underwent penetrating keratoplasty by using domestic and imported donor corneas between January 2013 and December 2013. The donor characteristics, preoperative clinical features, and clinical outcomes at 6, 12, 24, and 36 months were assessed.
Purpose: To assess and compare the outcomes of trabeculectomy with and without antimetabolites (AMs) and glaucoma drainage devices (GDDs) in the management of elevated intraocular pressure (IOP) after penetrating keratoplasty (PK).
Methods: Data of 84 eyes of 81 patients who underwent trabeculectomy (12 eyes without an AM and 42 eyes with an AM) or GDD implantation (30 eyes) after PK were reviewed retrospectively. The main outcome measures were IOP control, corneal graft survival, and postoperative ocular complications.
Background: To evaluate the ocular findings in children between 3 and 5 years of age who had received phototherapy in the neonatal period and to investigate whether they had phototherapy-related permanent ocular damage clinically.
Methods: The phototherapy group (n = 57) consisted of children who had undergone phototherapy for at least 24 h, and the control group (n = 43) comprised children who had not received phototherapy. Ophthalmic examinations consisted of assessment of visual acuity, convergence near point, ocular movements, ocular alignment, dynamic retinoscopy, cycloplegic refraction and biomicroscopic examination of anterior segment and posterior segment (using a 90 D lens in the latest).
