A comparison of NCT, Goldman application tonometry values with and without fluorescein.

Purpose: The aim of the study was to statistically compare intraocular pressure (IOP) values measured using noncontact tonometer (NCT), Goldmann applanation tonometry (GAT) with fluorescein (fGAT), and GAT without fluorescein (nGAT). The study was also performed to test whether the values obtained using each technique change in accordance with the central corneal thickness (CCT) and refractive and keratometric values.

Study Design: This study was a prospective study of 188 eyes of 94 healthy volunteers.

Helvacioglu reproducibility index: a new algorithm to evaluate the effects of misalignments on the measurements of retinal nerve fiber layer by spectral-domain OCT.

Aim: To evaluate the effect of misalignment on the measurements of retinal nerve fiber layer (RNFL) by spectral-domain optical coherence tomography (OCT).

Methods: A total of 42 eyes from 21 healthy young subjects underwent RNFL measurements with RTVue spectral-domain OCT (Optovue Inc., Fremont, California, USA).

Optical coherence tomography of bilateral nanophthalmos with macular folds and high hyperopia.

Importance. There is a conflict about the content of the macular folds in nanophthalmic eyes in the literature. Our study clearly demonstrated that papillomacular folds seen in nanophthalmos or posterior microphthalmos were only composed of neurosensory retina without involvement of retinal pigment epithelium and choroid.

Comparison of two different ultrasound methods of phacoemulsification.

Purpose: To compare the safety and efficacy of microcoaxial phacoemulsification surgeries performed with the OZil Intelligent Phaco torsional mode (Alcon Laboratories, Inc., Fort Worth, USA) and combined torsional/longitudinal ultrasound mode using 45 degree aperture angled tips.

Design: Prospective randomized clinical trial.

Outcomes of torsional microcoaxial phacoemulsification using tips with 30-degree and 45-degree aperture angles.

Purpose: To compare the safety and efficacy of Ozil Intelligent Phaco torsional microcoaxial phacoemulsification surgeries performed using 30-degree and 45-degree aperture angled tips.

Setting: Maltepe University School of Medicine Department of Ophthalmology, Istanbul, Turkey.

Design: Comparative case series.

Histologic Findings of Corneal Buttons in Decompensated Corneas With Toxic Anterior Segment Syndrome After Cataract Surgery.

Purpose: To report the histologic findings of penetrating keratoplasty buttons in decompensated corneas with toxic anterior segment syndrome (TASS) after a cataract surgery is performed.

Methods: We evaluated the histologic findings of 16 corneal buttons of 16 patients who exhibited decompensation findings because of TASS by means of light microscopy. The patients were classified into 3 groups: The first group consisted of 5 corneal buttons with mild symptoms in which the central corneal thicknesses (CCTs) were ≤650 μm, and the visual acuities (VAs) were ≥0.

Outcomes of torsional microcoaxial phacoemulsification performed by 12-degree and 22-degree bent tips.

Purpose: To compare the safety and efficacy of Ozil Intelligent Phaco torsional microcoaxial phacoemulsification surgeries performed with 12-degree and 22-degree bent tips using the Infiniti Vision System.

Setting: Maltepe University School of Medicine Department of Ophthalmology, Istanbul, Turkey.

Design: Comparative case series.

Evaluation of intrastromal corneal ring segments for treatment of keratoconus with a mechanical implantation technique.

Purpose: To evaluate the clinical outcomes of intrastromal corneal ring segment (ICRS) implantation in patients with keratoconus using a mechanical implantation technique.

Materials And Methods: Thirty eyes of 17 patients with keratoconus were enrolled. ICRSs (Keraring) were implanted after dissection of the tunnel using Tunc's specially designed dissector under suction.

Supraciliary contraction segments: a new method for the treatment of presbyopia.

Background And Objective: To evaluate the safety and effectiveness of supraciliary contraction segment implants (SCSIs) for the treatment of presbyopia.

Materials And Methods: This prospective, non-comparative study comprised 10 eyes from five phakic and emmetropic 50-year-old subjects. Preoperative and postoperative near and distance visual acuity, topography, axial length, pachymetry, and intraocular pressure were analyzed.

Ozil IP torsional mode versus combined torsional/longitudinal microcoaxial phacoemulsification.

Purpose: To compare the safety and efficacy of microcoaxial phacoemulsification surgeries performed with the Ozil Intelligent Phaco (IP) torsional mode and combined torsional/longitudinal ultrasound (US) mode using the Infiniti Vision System (Alcon Laboratories).

Methods: In this prospective randomized comparative study, 60 eyes were assigned to 2.2-mm microcoaxial phacoemulsification using the Ozil IP torsional mode (group 1) or combined torsional/longitudinal US mode (group 2).

Evaluation of intrastromal corneal ring segments for treatment of post-LASIK ectasia patients with a mechanical implantation technique.

Aim: To evaluate the clinical outcomes of Keraring segment implantation in patients with post- laser-assisted in situ keratomileusis (LASIK) ectasia, using a mechanical implantation technique.

Materials And Methods: Twelve eyes of 10 patients with post-LASIK ectasia were enrolled. Intracorneal ring segments (ICRS) were implanted after dissection of the tunnel using Tunc's specially designed dissector under suction.

Fixed, dilated pupil after phakic intraocular lens implantation.

A 26-year-old man with degenerative high myopia had bilateral anterior chamber phakic intraocular lens (IOL) implantation under general anesthesia. The preoperative slitlamp examination was normal. No mydriatic drops were used before, during, or after the procedure.
