JCAHPO Certified Ophthalmic Assistant - Why Exam Edge Sample Questions

What is an aspheric lens designed to do?

Correct Answer:
eliminate pincushion distortions of the aphakic patient


an aspheric lens is specially designed to eliminate distortions in vision, particularly pincushion distortions, which are more common in aphakic patients. aphakia is a condition where the eye's natural crystalline lens is absent. this can occur due to surgical removal during cataract surgery, or less commonly, due to a congenital absence or trauma. normally, the crystalline lens of the eye helps to focus light onto the retina, but when it is missing, optical devices such as glasses or contact lenses are needed to correct vision.

standard spherical lenses, commonly used in glasses, have a uniform curvature across their surface. while effective in correcting vision, they often introduce certain optical aberrations or distortions, such as pincushion distortion. pincushion distortion makes images appear pinched at the center, causing straight lines to curve inward towards the center of the visual field. this can be particularly disorienting for aphakic patients, affecting their spatial perception and visual comfort.

aspheric lenses address these issues by having a non-uniform curvature. their surface curvature gradually changes from the center to the edge of the lens, which helps to focus light more precisely on the retina. this design reduces the spherical aberration and other distortions associated with spherical lenses. consequently, aspheric lenses provide clearer, sharper vision with less visual noise, improving both the quality of sight and the overall visual experience for the wearer.

for aphakic patients, the use of aspheric lenses is particularly beneficial. by eliminating pincushion distortions, these lenses help in restoring a more natural and accurate visual field, which is crucial for performing daily activities and maintaining independence. moreover, aspheric lenses are often thinner and lighter than conventional spherical lenses, offering aesthetic and comfort advantages, which contribute to patient satisfaction.

in summary, aspheric lenses are essential in optimizing visual correction for aphakic patients by eliminating undesirable distortions and enhancing visual clarity and comfort. their tailored design and advanced optical properties make them an ideal choice for addressing the specific challenges faced by individuals without a natural crystalline lens.
