Pterygium surgery using the principle of contact inhibition: results of 13 years' experience.

Purpose: To report a technique to prevent pterygium recurrence using the principle of contact inhibition.

Methods: Two hundred and fifteen patients (232 eyes; average age, 64.1 years) with primary pterygia who underwent pterygium surgery at the Hara Eye Hospital between 1999 and 2012.

Posterior capsular opacification in highly myopic eyes with an endocapsular equator ring.

Purpose: Closed 9.5-mm-diameter endocapsular equator rings (E-rings) prevent posterior capsular opacification (PCO). However, in our research, some highly myopic patients unexpectedly developed late, extensive PCO that required capsulotomy.

Structure of the entire capsular bag containing an endocapsular equator ring and intraocular lens.

Unlabelled: We report in vivo observation of a capsular bag containing an endocapsular equator ring and intraocular lens that was explanted 5 years after the initial surgery. The capsule equator remained completely circular. The inside of the capsular bag retained the open space, and the endocapsular equator ring blocked proliferative tissue under the anterior capsule at the equator and prevented posterior capsule opacification.

Long-term study of posterior capsular opacification prevention with endocapsular equator rings in humans.

Objective: To confirm the effect of a square-edged, closed endocapsular equator ring (E-ring) for preventing posterior capsular opacification (PCO) after cataract extraction.

Methods: Fifty-one eyes underwent cataract surgery associated with E-ring implantation between October 2002 and March 2008. Group 1 included 14 patients (14 eyes) who received an E-ring and intraocular lens (IOL) in 1 eye before March 2006.

Infero-eyebrow blepharoplasty for the upper eyelids of elderly patients.

Aims: To describe a procedure for removing excess wrinkles from the upper lids of elderly patients.

Methods: Excess wrinkles were resected with a razor blade and scissors or CO(2) laser along the lower eyebrow margin. Ninety-five patients (average age 74 ± 8.

Generation of high-quality higher-order Laguerre-Gaussian beams using liquid-crystal-on-silicon spatial light modulators.

We report on the high-quality holographic generation of higher-order Laguerre-Gaussian (LG) beams using a liquid-crystal-on-silicon spatial light modulator. The effects of the input beam pattern on the output LG beam quality are investigated in detail through theoretical discussions and experiments. Correlation analyses between observed beam patterns and theoretical mode profiles reveal that higher beam quality is achieved for output LG beams generated from a top-hat input beam than from a Gaussian input beam.

Epithelial photorefractive keratectomy as an enhancement procedure after laser in situ keratomileusis.

The authors describe the refractive effect of epithelial photorefractive keratectomy (E-PRK) on 10 eyes that had undergone LASIK (group 1) and 13 eyes that had not been operated on (group 2). The central 6 mm was ablated. The mean corneal epithelium removed was 15.

Universal generation of higher-order multiringed Laguerre-Gaussian beams by using a spatial light modulator.

Laguerre-Gaussian (LG) beams of various higher-order radial modes are generated by using a reflective phase-only liquid crystal on silicon (LCOS) spatial light modulator (SLM). Because of the LCOS SLM's phase-modulation characteristic of a wide spatial bandwidth, a phase modulation scheme effectively generates higher-order LG beams of up to the fifth-order radial mode. We also perform correlation analyses between the observed and the theoretical two-dimensional mode profiles to universally obtain correlation coefficients of more than 0.

Preventing posterior capsular opacification with an endocapsular equator ring in a young human eye: 2-year follow-up.

Objective: To report the results of a specially designed closed ring with a square edge (endocapsular equator ring) in a young patient to prevent posterior capsular opacification.

Methods: One eye of a 22-year-old atopic patient underwent endocapsular equator ring implantation with a 1-piece polymethylmethacrylate intraocular lens immediately after phacoemulsification at Hara Eye Hospital on January 10, 2003. The solid flexible silicone ring has an outer diameter of 9.

Total care system for maintaining a comfortable prone position after vitreoretinal surgery.

A care system to maintain a comfortable prone position after vitreoretinal surgery was developed. Four positions and face-down gear including a TV-watching table were prepared in patients' rooms. Patients could take one position and then change to another position actively as desired.

Increase of peak intraocular pressure during sleep in reproduced diurnal changes by posture.

Objective: To characterize diurnal intraocular pressure (IOP) changes in primary open-angle glaucoma by reproducing IOPs based on patient posture.

Methods: In 148 patients with untreated primary open-angle glaucoma who had IOPs recorded during clinic hours that were less than 21 mm Hg (average, 14.8 +/- 3.

Ten-year results of anterior chamber fixation of the posterior chamber intraocular lens.

Objective: To report the outcomes in eyes in which a Sinskey-type conventional posterior chamber intraocular lens (PC-IOL) was fixed in the anterior chamber and followed up for an average of 10 years.

Methods: Twenty-one eyes were included in the study. The IOLs were conventional hard PC-IOLs, 13.

Lipoprotein lipase activator NO-1886 improves fatty liver caused by high-fat feeding in streptozotocin-induced diabetic rats.

NO-1886 is a lipoprotein lipase (LPL) activator. Administration of NO-1886 results in an increase in plasma high-density lipoprotein cholesterol (HDL-C) and a decrease in plasma triglyceride (TG) levels. The aim of this study was to ascertain whether NO-1886 improves fatty liver caused by high-fat feeding in streptozotocin (STZ)-induced diabetic rats.

Ethyl icosapentate (omega-3 fatty acid) causes accumulation of lipids in skeletal muscle but suppresses insulin resistance in OLETF rats. Otsuka Long-Evans Tokushima Fatty.

Ethyl icosapentate (EPA) is known to improve insulin resistance in non-insulin-dependent diabetes mellitus (NIDDM); however, its mechanism is unclear. In this study, we attempted to determine the mechanism of EPA's effects on insulin resistance in Otsuka Long-Evans Tokushima Fatty (OLETF) rats. Administration of EPA caused a reduction in plasma cholesterol and triglycerides, but increased cholesterol and triglyceride contents in skeletal muscle.

A lipoprotein lipase activator, NO-1886 prevents impaired endothelium-dependent relaxation of aorta caused by exercise in aged rats.

Exercise decreases plasma total cholesterol and triglycerides, and simultaneously, increases high density lipoprotein (HDL) cholesterol. As a result, exercise is believed to aid in preventing atherosclerosis. However, we do not know whether exercise protects against the development of atherosclerosis in the elderly.

Correlation between lipid and glycogen contents in liver and insulin resistance in high-fat-fed rats treated with the lipoprotein lipase activator NO-1886.

Insulin resistance results in accumulation of triglyceride content and reduction of glycogen content in skeletal muscle. However, very few studies have measured lipid content and glycogen content in liver associated with insulin resistance. We studied the relationship between liver lipid content, liver glycogen, and insulin resistance in high-fat-fed rats, which are animal models of insulin resistance.
