In contrast, the automated CST device made use of bull’s-eye sine-wave gratings, which is a rotationally symmetric target. For two patients with the same magnitude of astigmatism but at different orientations, the target will appear the same, and no advantage or disadvantage will happen based...

This study involved thirty Malay university students aged between 19 and 23 years old (7 males, 23 females), with their spherical refractive error ranging between plano and 7.75D, astigmatism ranging from plano to 1.75D, anisometropia less than 1.00D and with no history of ocular injury or pa...
Methods: The clinical charts of 687 patients (1374 eyes) with mean age 27.6 ± 7.5 years who desired laser vision correction and underwent a pre-LASIK work-up were reviewed retrospectively. Refractive errors were classified as myopia, hyperopia and astigmatism. Manifest refraction spherical ...
The classroom allows you to pick myopia, presbyopia, and astigmatism. For Myopia and Presbyopia, visitors can select none or levels 1, 2, or 3. Level 1 is mild and Level 3 is severe. Astigmatism is different from the other two as it can distort and blur a person’s vision. It can ...
patients with &62; 4 D of hypermetropia(p&61;0.028), without correction after treatment (p&61;0.235).The initial binocular BCVA was not different betweenastigmatism groups, but final BCVA levels were significantlylower in 4-6D of astigmatism compared with 2-4D of astigmatism (p&61;0.001). ...
Long-term Analysis of Surgically Induced Astigmatism after Combined Vitrectomy and Cataract Surgery versus Cataract Surgery Alone Flat keratometry (K1), steep keratometry (K2), and astigmatism axis were measured with automatic keratometry before and after the surgery. Vector analysis ... Z. Byun,Jung...
Methods: This study included 112 right eyes of 112 patients who previously underwent WFG FS-LASIK for correcting myopia and myopic astigmatism. The patients were divided into two groups based on the mean values of preoperative total ocular HOAs (0.30 ± 0.09 m): HOA ≤ 0.3 and >...

The error in predicted residual astigmatism was ...
