Vision improvement by correcting higher-order aberrations with customized soft contact lenses in keratoconic eyes.
Higher-order aberration correction in abnormal eyes can result in significant vision improvement, especially in eyes with abnormal corneas. Customized optics such as phase plates and customized contact lenses are one of the most practical, nonsurgical ways to correct these ocular higher-order aberrations. We demonstrate the feasibility of correcting higher-order aberrations and improving visual...
متن کاملBiomicroscopy of papillae associated with wearing of soft contact lenses.
We studied the topographical, macrostructural, and fluorescein staining characteristics of papillary changes of the upper tarsal conjunctiva associated with the wearing of hydrophilic (soft) contact lenses. Fifty soft contact lens wearers with elevated conjunctival papillae greater than 0.3 mm in diameter were studied. Topographic characteristics recorded were distribution and number of papilla...
متن کاملGeneration of Higher Order Aberrations with Soft Contact Lens by Excimer Laser Ablation
Although the human eye has a relatively simple optical system, it is not perfect. It has been well known that the human eye suffers from the wavefront aberration that includes both lower (defocus and astigmatism) and higher order aberrations. The lower order aberration has been effectively corrected with conventional ophthalmic lenses such as spectacles and contact lenses. However, it is more c...
متن کاملThe impact of wearing single vision soft contact lenses on the peripheral refractive error
The purpose of this study was to determine the changes in the relative Aim: peripheral refractive error produced by soft single vision contact lenses in myopic schoolchildren. 27 myopic schoolchildren aged between 13 to 15 years were Methods: included in this study. The measurements of central and peripheral refraction were made only on the right eye using a Grand-Seiko WR-5100K open-field auto...
متن کاملComparison of fitting stability of the different soft toric contact lenses.
PURPOSE To compare lens orientation and rotational recovery of five currently available soft toric lenses. METHODS Twenty subjects were recruited and trialed with each of the study lenses in a random order. Study lenses were PureVision(®) Toric (B&L), Air Optix(®) for Astigmatism (Alcon), Biofinity(®) Toric (CooperVision), Acuvue(®) Advance for Astigmatism (Vistakon), and Proclear(®) Toric (C...
