Effect of pupil size on uncorrected visual acuity in astigmatic eyes.
AIM To determine the effects of pupil size on uncorrected visual acuity (UCVA) in astigmatic eyes. METHODS The authors examined 20 normal eyes of 20 healthy volunteers (age 26.7±4.9 years (mean±SD); 8 men, 12 women). After fully correcting cycloplegic refraction, the authors created with-the-rule and against-the-rule astigmatism of 1, 2, and 3 dioptres (D) in each eye, and then assessed UCVA ...
متن کاملEffect of pupil size on uncorrected visual acuity in pseudophakic eyes with astigmatism.
PURPOSE To study the effect of pupil size on the relationship between refractive astigmatism and uncorrected distance visual acuity (UDVA) and pseudoaccommodation in pseudophakic eyes. METHODS Thirty-six eyes from 36 patients who underwent phacoemulsification and intraocular lens (IOL) implantation were included. All eyes were divided into two groups based on the presence of postoperative-wit...
متن کاملEffect of Pupil Size on Optical Quality Parameters in Astigmatic Eyes Using a Double-Pass Instrument
PURPOSE To objectively determine the effects of pupil size on optical quality parameters in astigmatic eyes using a double-pass instrument. METHODS We examined twenty-two eyes of 22 healthy volunteers (mean age ± standard deviation, 27.1 ± 2.8 years) who had no ophthalmic diseases other than refractive errors (manifest cylinder ≤ 0.25 diopters (D)). After we fully corrected cycloplegic refr...
متن کاملEffect of axis orientation on visual performance in astigmatic eyes.
PURPOSE To determine the effect of axis orientation on visual performance in astigmatic eyes. SETTING Department of Ophthalmology, Kitasato University, Kanagawa, Japan. DESIGN Investigational simulation. METHODS Healthy volunteers with no ophthalmic disease other than refractive errors were enrolled. After cycloplegic refraction was fully corrected with a 3.0 mm artificial pupil, with-the...
متن کاملEffect of Pupil Size on Trust
During close interactions with fellow group members, humans look into one another’s eyes, follow gaze, and quickly grasp emotion signals. The eye-catching morphology of human eyes, with unique eye whites, draws attention to the middle part, to the pupils, and their autonomic changes, which signal arousal, cognitive load, and interest (including social interest). Here, we examined whether and ho...
