Optical Quality and Visual Performance With Different Toric Contact Lens Designs.

Objectives: To evaluate the optical quality of different toric contact lens (CL) designs and compare their on-eye visual correction performance.

Methods: Twenty soft CL wearers aged 20 to 39 years were enrolled. Two daily disposable silicone-hydrogel toric CLs were tested: the "Eyelid Stabilized Design" (ESD-CL) and prism-ballast design (PB-CL); a spherical daily disposable silicone hydrogel CL (spherical CL) was used as a control.

Case of Primary Intraocular Lymphoma with Extraocular Extension.

Purpose: To describe a case of primary intraocular lymphoma (PIOL) with an extension through the sclera that was confirmed to be part of the PIOL by histopathological examinations.

Case: An 89-year-old woman was referred to a local clinic with a 1-year history of persistent blurred vision in her left eye. After 2 years without aggressive treatments, she had a marked reduction of vision and pain in her left eye.

Higher-order aberrations of anterior and posterior corneal surfaces in patients with keratectasia after LASIK.

Purpose: We investigated higher-order aberrations (HOAs) of the anterior and posterior corneal surfaces in patients with keratectasia after LASIK.

Methods: The subjects comprised four groups: 12 eyes with keratectasia after LASIK, 30 eyes following LASIK without keratectasia, 30 keratoconic eyes, and 30 normal eyes. Corneal HOAs due to the anterior and posterior corneal surfaces for 6-mm pupils (root mean square [μm]) were obtained using a Scheimpflug-based corneal tomographer and compared among the four groups.

[Higher-order aberrations in eye implanted with aspherical intraocular lenses].

Purpose: To compare efficacy of aspherical intraocular lenses (IOLs) with spherical IOLs by measuring the ocular and internal higher-order aberrations.

Methods: Two hundred four eyes of 145 patients were evaluated at Kozaki eye clinic after phacoemulsification with implantation of 2 aspherical IOLs (45 eyes with the Hoya FY60AD, and 43 eyes with the Nidek N4-18YG); or 3 spherical IOLs (38 eyes with the Hoya YA60BBR, 32 eyes with the Kowa AU6K and 46 eyes with the Alcon MZ30BD). The 3rd and 4th higher-order aberrations (HOAs) were measured with KR9000PW for a 6-mm-diameter pupil, and then the ocular and internal HOAs were compared between the groups.

Effect of NIDEK optimized aspheric transition zone ablation profile on higher order aberrations during LASIK for myopia.

Purpose: To investigate the effect of the Optimized Aspheric Transition zone profile (OATz) that was devised to minimize the "red ring" in corneal topography on ocular higher order aberrations following LASIK for myopia.

Methods: Laser in situ keratomileusis with OATz using the Nidek Advanced Vision Excimer Laser Platform (NAVEX) was performed on 22 eyes with a 4.5-mm optical zone and 8.

Higher-order aberrations due to the posterior corneal surface in patients with keratoconus.

Purpose: This study was designed to investigate higher-order aberrations (HOAs) due to the posterior corneal surface in keratoconic eyes compared with normal eyes.

Methods: We studied 24 normal and 28 keratoconic eyes. The anterior/posterior corneal heights and pachymetric data were obtained with a rotating Scheimpflug camera.

Characteristics of ocular higher-order aberrations in patients with pellucid marginal corneal degeneration.

Purpose: To evaluate the characteristics of higher-order aberrations (HOAs) in eyes with pellucid marginal corneal degeneration (PMCD).

Setting: Department of Ophthalmology, Osaka University Medical School, Osaka, Japan.

Methods: Ocular HOAs were measured by aberrometry in 20 eyes with PMCD (PMCD group), 76 eyes with keratoconus (KC group), and 105 normal eyes (control group) with a 4.

Three cases of idiopathic "multiple-parallel-line" endotheliitis.

Purpose: To report 3 cases of idiopathic endotheliitis that appeared clinically as multiple parallel lines of keratic precipitates on the corneal endothelium.

Methods: Interventional case reports.

Results: Slit-lamp examinations of the 3 patients showed several parallel dotted lines of keratic precipitates on the corneal endothelium.

Magnitude and orientation of Zernike terms in patients with keratoconus.

Purpose: To measure the magnitude and orientation of the Zernike terms in keratoconic eyes, with and without rigid gas-permeable (RGP) contact lenses.

Methods: A total of 76 eyes with keratoconus, 58 eyes with keratoconus suspect, and 105 normal eyes were studied. To determine the effect of RGP lenses, 19 eyes with keratoconus, 9 eyes with keratoconus suspect, and 17 normal eyes, with and without an RGP lenses, were compared.

The use of competitive PCR for quantitation of HSV-1 DNA.

Purpose: Polymerase chain reaction (PCR) detects the genomic materials of etiological agents with high specificity and sensitivity. However, in herpes simplex virus type 1 (HSV-1) infection, the clinical significance of the results often poses controversy because of the subclinical viral shedding during latent infection. Quantitative PCR might provide additional information to help clinical evaluation of the results.
