Purpose: The length of Descemet's membrane and donor graft sizes in deep anterior lamellar keratoplasty do not match in very steep corneas, which can lead to Descemet's membrane folds. The aim of this study is to establish a theoretical model for graft size calculations for deep anterior lamellar keratoplasty and evaluate its efficacy for preventing Descemet's membrane folds.
Methods: We calculated the arc diameter of the recipient bed by using the cosine formula and developed a table to aid surgeons in donor punch size selection.
This report describes a case of hypotony maculopathy developing in a patient with GAPO syndrome following a trabeculectomy with mitomycin C (MMC). A 42-year-old man with a diagnosis of GAPO syndrome underwent a trabeculectomy with an MMC application of 0.4 mg/mL for 1 minute.

Methods: The study included seven eyes of seven patients with previous PK who underwent circular keratotomy combined with wedge resection. The uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), spherical equivalent (SE) refraction, and keratometric powers obtained by corneal topography were evaluated.
Purpose: Evaluation of the etiopathogenesis and management of topographic reverse pellucid pattern after rigid intraocular lens (IOL) implantation with wide limbal clear corneal incision (CCI).
Methods: Fifteen eyes with a history of gradual decrease in vision after IOL surgery with at least 6.5-mm CCI were diagnosed with wound dehiscence and were managed with tight resuturation, delayed, and selective suture removal.
Objective: To evaluate the effectiveness of crescentic corneal lamellar wedge resection for the treatment of pellucid marginal degeneration (PMD) in improving refractive, visual, and corneal aberrometry.
Methods: The study included 10 eyes of 10 patients who had undergone corneal lamellar wedge resection for PMD. Pellucid marginal degeneration was diagnosed based on the clinical signs and corneal topography.
Purpose: The authors report a case with multiple iris burns after conductive keratoplasty to correct hyperopia.
Methods: Case report.
Results: A 52-year-old woman with hyperopia had a previous conductive keratoplasty procedure and underwent a conductive keratoplasty re-treatment 6 months later.
Intraoperative complications in intumescent cataract surgery using a phaco capsulotomy technique.

August 2016
Purpose: To evaluate intraoperative complications of a modified phaco capsulotomy technique and the ophthalmic viscosurgical device (OVD)-assisted capsulorhexis in eyes with intumescent white cataract.
Setting: Lütfi Kırdar Kartal Eye Training and Research Hospital, Department of Ophthalmology, Istanbul, Turkey.
Design: Comparative randomized case study.
Corneal collagen crosslinking for ectasia after laser in situ keratomileusis: long-term results.
J Cataract Refract Surg
October 2014
Purpose: To report the long-term results of corneal collagen crosslinking (CXL) treatment for post-laser in situ keratomileusis (LASIK) ectasia.
Settings: Turkiye Hospital Eye Clinic and Fatih University Medical Faculty, Department of Ophthalmology, Istanbul, Turkey.
Design: Retrospective case series study.
Long-term outcomes of intrastromal corneal ring segment implantation for post-LASIK ectasia.
Cont Lens Anterior Eye
December 2014
Purpose: To report the long-term results of intrastromal corneal ring segments (ICRS) for postoperative LASIK ectasia.
Method: In this retrospective interventional cases series, 8 eyes of 6 patients who underwent femtosecond laser-assisted ICRS implantation for post-LASIK ectasia were enrolled. Main outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical equivalent refraction, and average keratometry (Kavg) values were assessed.
Article Synopsis
- The study evaluated the long-term effectiveness of combining intrastromal corneal ring segment placement with corneal collagen cross-linking (CXL) in patients experiencing ectasia after LASIK surgery.
- Sixteen eyes from 14 patients were treated, showing significant improvements in uncorrected and corrected distance visual acuity, as well as reductions in both spherical and cylindrical refraction after an average follow-up of 43 months.
- No serious complications were observed, indicating that this combined treatment approach is both safe and effective for managing postoperative LASIK ectasia.
Objective: To compare visual outcomes, corneal astigmatism, and keratometric readings in patients with progressive keratoconus undergoing intrastromal corneal ring implantation (ICRSI) only and in combination with ultraviolet A riboflavin mediated corneal collagen crosslinking (CXL).
Methods: In this retrospective comparative study, there were 2 groups of keratoconus patients. Group 1 consisted of only ICRSI patients.
Purpose: To report the use of intracorneal ring segment (ICRS) implantation in a case of severe corneal thinning and irregularity secondary to alkali burn.
Case Report: A 33-year-old man who had a history of ocular alkali burn in the right eye was admitted. His best corrected visual acuity was 0.
Purpose: To evaluate the long-term visual results of Acufocus ACI-7000 (now Kamra) intracorneal inlay implantation in presbyopic phakic patients.
Setting: Beyoğlu Eye Training and Research Hospital, Istanbul, Turkey.
Design: Clinical trial.
PURPOSE:To evaluate the results of combined intracorneal ring (Keraring, Mediphacos Ltd) and anterior chamber, iris-fixated, phakic intraocular lens (pIOL) (Artisan and Artiflex, Ophtec BV) implantation in patients with ectatic corneal conditions and secondary high myopic and astigmatic refractive error. METHODS:Ten eyes of eight consecutive patients with different ectatic corneal diseases underwent sequential intracorneal Keraring and iris-fixated pIOL implantation. Two eyes with keratoconus, one eye with pellucid marginal degeneration, and one eye with iatrogenic corneal ectasia were implanted with the Artisan pIOL; six eyes with keratoconus were implanted with the Artiflex pIOL.

Methods: In this cross-sectional study, 42 eyes of 42 patients with a mean SE of - 4.69 +/- 4.
Purpose: To evaluate the results of LASIK for hyperopia in pediatric eyes with amblyopia resulting from anisometropia.
Methods: Thirty-two children with anisometropic amblyopia in whom conventional therapy was unsuccessful underwent unilateral LASIK between 1999 and 2005. Mean patient age was 10.
Background: Vogt-Koyanagi-Harada syndrome (VKH) is a multisystem disorder, characterized by the T-cell-mediated autoimmune process directed against melanocytic antigens in the ocular, nervous, auditory and integumentary systems. The ocular hallmarks of the disease involve severe bilateral panuveitis associated with exudative retinal detachment.
Case Report: We report a pediatric case of probable VKH Syndrome with isolated ocular findings, in which bilateral vitritis, papillitis and serous retinal detachments involving the macula with intra-retinal edema and choroideal thickening were detected.
Purpose: To report a case of laser in situ keratomileusis (LASIK) that used the Intralase femtosecond laser 14 years after radial keratotomy (RK) for residual myopic astigmatism.
Methods: A 39 year-old male patient had undergone a bilateral RK operation for myopic correction. The manifest refraction was -1.
