Low-order and high-order aberrations are types of optical imperfections in the eye that affect vision quality. Here’s a breakdown of each: Low-Order Aberrations (LOAs): These are common refractive errors that can be corrected with glasses, contact lenses, or basic refractive surgery (like LASIK). Types: Myopia (Nearsightedness): When the eye is too long or the cornea is too curved, causing distant objects to appear blurry. Hyperopia (Farsightedness): When the eye is too short or the cornea is too flat, making near objects appear blurry. Astigmatism: When the cornea or lens has an irregular shape, causing blurred or distorted vision at all distances. Effect on vision: These errors can usually be corrected to 20/20 vision with standard corrective lenses. High-Order Aberrations (HOAs): These are more complex optical imperfections that cannot be fully corrected with glasses or standard contact lenses. Types: Coma: A distortion that causes light points (like stars) to appear smeared or stretched, often in a comet-like shape. Spherical Aberration: Occurs when light rays entering the eye at different distances from the optical axis focus at different points, leading to blurry or distorted vision, especially in low-light conditions. Trefoil, Tetrafoil, etc.: More complex distortions that affect visual clarity. Effect on vision: These aberrations can cause halos, glare, starbursts, or reduced contrast sensitivity, particularly noticeable at night or in low-light conditions. They typically reduce the overall quality of vision even if the person has 20/20 visual acuity. ________________________________________________________________________ Motwani LASIK Institute / Cornea Revolution is the most technologically advanced laser center in the United States performing supranormal LASIK/PRK and corneal repair for keratoconus, RK/LASIK/PRK/corneal scar repair.
