Management of Dry Eye Disease for Intraocular Lens Power Calculation in Cataract Surgery: A Systematic Review.

Cataracts are characterized by the crystalline lens of the eye becoming cloudy, and dry eye disease (DED) is a multifactorial disease in which the homeostasis of the tear film is lost. As the prevalence of both diseases increases with age, there is a high prevalence of DED among patients who are candidates for cataract surgery. In recent years, cataract surgery has evolved from vision restoration surgery to refractive surgery.

Treatment of Dry Eye Disease (DED) in Asia: Strategies for Short Tear Film Breakup Time-Type DED.

Dry eye disease (DED) is a multifactorial disorder in which tear fluid homeostasis is lost, resulting in increased tear film osmolarity and ocular surface irritation. In Asia, the short tear film breakup time-type DED, which has become a global problem in recent years, is common. While the mainstay of DED treatment in the West is the suppression of inflammation, the first goal of treatment is the stabilization of the tear film in Asia.

A very early steroid responder after cataract surgery: a case report.

Background: Increased intraocular pressure (IOP), a side effect of corticosteroid eye drops, typically develops during the first few weeks of administration, and steroid response is not generally considered a cause of increased IOP immediately after cataract surgery.

Case Presentation: Here, I report a rare case of increased IOP due to steroid eye drops immediately after surgery. A man in his 80s presented with vision loss.

Predicting Residual Astigmatism in Cataract Surgery.

The purpose of this review is to evaluate the prediction of postoperative residual astigmatism and to determine the best prediction method for astigmatism correction. In recent findings for residual astigmatism in non-toric monofocal intraocular lens (IOL) implanted eyes, vector analysis can be used to correctly evaluate residual astigmatism by decomposing it. In predicting residual astigmatism, the with-the-rule (WTR) and against-the-rule (ATR) astigmatism components can now be almost predicted.

Prediction of postoperative refractive astigmatism before toric intraocular lens implantation.

Background: To determine the preoperative factors influencing refractive astigmatism after cataract surgery for astigmatism correction by toric intraocular lens (IOL) implantation and to evaluate the prediction model using these factors.

Methods: Prospective, observational case series. The right eyes of forty consecutive patients with preoperative corneal astigmatism of the total cornea of 1.

Multivariate Regression Analysis to Predict Postoperative Refractive Astigmatism in Cataract Surgery.

Purpose: To assess the correlation between postoperative refractive astigmatism and preoperative parameters in cataract surgery.

Methods: Left eyes of 100 consecutive patients scheduled for cataract surgery with a 2.4 mm clear corneal incision were examined prospectively.

Acoustic emissions of (Mammalia: Soricidae): Assessing the echo-based orientation hypothesis.

Shrew species have been proposed to utilize an echo-based orientation system to obtain additional acoustic information while surveying their environments. This system has been supported by changes in vocal emission rates when shrews encounter different habitats of varying complexity, although detailed acoustic features in this system have not been reported. In this study, behavioral experiments were conducted using the long-clawed shrew () to assess this orientation system.

Comparison of refractive and keratometric astigmatism after microincision cataract surgery.

Purpose: To measure the correlation between refractive and keratometric astigmatism after microincision cataract surgery (MICS).

Setting: Takayanagi Clinic, Kushiro, Hokkaido, Japan.

Design: Retrospective case series.

Effects of Diquafosol Ophthalmic Solution on Quality of Life in Dry Eye Assessed Using the Dry Eye-Related Quality-of-Life Score Questionnaire: Effectiveness in Patients While Reading and Using Visual Display Terminals.

Purpose: Diquafosol ophthalmic solution improves objective findings in the ocular surface and subjective symptoms in patients with dry eye. The Dry Eye-Related Quality-of-Life Score (DEQS) questionnaire was developed to assess dry eye symptoms and their effects on quality of life. However, because little research using the DEQS has been reported, we evaluated the effects of diquafosol ophthalmic solution on ocular surface findings and quality of life using the DEQS in patients with dry eye.

Vector analysis investigation of toric intraocular lens with no deviation from the intended axis.

Aim: The aim of this research was to evaluate vector analysis after implantation of toric intraocular lenses (IOLs) without deviation from the intended axis.

Methods: The study included 18 eyes of 16 patients who underwent cataract surgery with the insertion of a toric implant (AcrySof IQ Toric). The postoperative IOL meridian placement completely corresponded to that planned.

Comparison of effect of nepafenac and diclofenac ophthalmic solutions on cornea, tear film, and ocular surface after cataract surgery: the results of a randomized trial.

Background: The aim of this study was to compare the effects of nepafenac ophthalmic suspension 0.1% (Nevanac) and diclofenac sodium ophthalmic solution 0.1% (Diclod) on the cornea, tear film, and ocular surface after cataract surgery.

Usefulness of 3-dimensional CT angiograms obtained by 64-section multidetector row CT scanner for dural arteriovenous fistula.

The authors reported a case of a dural arteriovenous fistula (DAVF) in the left transverse-sigmoid sinus, in which 3-dimensional computed tomography (CT) angiograms (3D-CTAs) by a 64-section multidetector row CT scanner were useful for its diagnosis and treatment. The DAVF in the left transverse-sigmoid sinus appeared on the digital subtraction angiogram. 3D-CTAs were obtained by a 64-section multidetector row CT scanner before an endovascular treatment.

Role of nitric oxide in regulation of retinal blood flow in response to hyperoxia in cats.

Purpose: To investigate whether nitric oxide (NO) regulates retinal circulation during and after induction of hyperoxia in cats.

Methods: Hyperoxia was induced for 10 minutes with 100% oxygen. The vessel diameter and blood velocity were measured simultaneously in second-order retinal arterioles by laser Doppler velocimetry; the retinal blood flow (RBF) and wall shear rate (WSR) were calculated during and after hyperoxia.

Adenosine agonist regulation of outward active transport of fluorescein across retinal pigment epithelium in rabbits.

To investigate the effect of an adenosine agonist, 2-5'-N-ethylcarboxamidoadenosine (NECA), on the outward active transport of fluorescein across the retinal pigment epithelium (RPE) in rabbits. High (5x10(-4)-2x10(-3) M) and low (1x10(-5)-1x10(-4) M) concentrations of NECA or phosphate buffered saline (PBS) were intravitreously injected into Dutch-belted rabbits. Sodium fluorescein was injected intravenously 180 min after NECA.
