Postoperative Astigmatic Outcomes Based on the Haptic Axis of Intraocular Lenses Inserted in Cataract Surgery
PURPOSE This study was conducted to compare post-operative astigmatic outcomes of two groups, with-the-rule (WTR) and against-the-rule (ATR) astigmatism patients, according to the haptic axis of intraocular lenses (IOLs) inserted in cataract surgery. METHODS Seventy-two eyes with WTR astigmatism and 79 eyes with ATR astigmatism had cataract surgery through a clear corneal temporal incision. T...
متن کاملComparison between toric and spherical phakic intraocular lenses combined with astigmatic keratotomy for high myopic astigmatism
BACKGROUND To compare the outcomes of a toric phakic intraocular lens (PIOL) and a spherical PIOL combined with astigmatic keratotomy (AK) for the correction of high myopic astigmatism. METHODS This study enrolled patients with high myopic astigmatism, including 30 eyes (22 patients) that received a toric PIOL implantation (TICL group), and 32 eyes (24 patients) that received combined AK and ...
متن کاملStudies on Copper Metabolism. Xix
Ferrokinetic studies were performed in three copper-deficient swine and the results have been compared with similar studies in 18 normal pigs. The mean value for the plasma iron turnover rate in the deficient swine was 1.76 mg./kg. day; for the red cell iron incorporation rate, 1.24 mg./kg. day; for the red cell iron turnover rate, 1.18 mg./kg. day; for the red cell life span, 13 days. Correspo...
متن کاملComparison of the Astigmatic Power of Toric Intraocular Lenses Using Three Toric Calculators
PURPOSE To compare the astigmatic power of toric intraocular lenses (IOLs) obtained from the AcrySof, TECNIS, and iTrace toric calculator in patients with preoperative with-the-rule (WTR) or against-the-rule (ATR) corneal astigmatism. MATERIALS AND METHODS Fifty eyes with cataract and corneal astigmatism greater than 0.75 diopters were enrolled in each group (WTR and ATR). Keratometric values...
متن کاملXix. Neurophysiology A. New Methods for Testing Camera Lenses (part Ii)
In Quarterly Progress Report No. 73 (pages 209-216) we described a new method for testing camera lenses and cameras. This method, which makes use of an especially designed analyzer lens placed in front of the camera lens, together with a polar coordinate test chart, permits simple diagnosis of the focal properties of the lenscamera combination. In particular, our method was shown to be sensitiv...
