Cycloplegic Effects on the Cylindrical Components of the Refraction
Journal of Ophthalmology, Volume 2021, Issue 1, 2021., 2021 It is important to predict which astigmatic patients require separate refraction for near vision. This study compared cylindrical components changes by cyclopentolate 1% for the low and high amount of astigmatism. The right eyes of 1014 healthy individuals (307 males and 707 females) with cylindrical refractive power more than −0.5 diopter on ...

Journal of Healthcare Engineering, Volume 2021, Issue 1, 2021., 2021 The front part of the eye is exposed to the surface of the body, making it susceptible to injury. Blunt eye injuries often destroy the tissue structure in the anterior part of the eye. Often there is detachment of the iris root, separation of the ciliary body, the angle of retraction of the chamber, and complete dislocation or subluxation of the lens ...

Changes in Higher-Order Aberrations after Scleral Buckling Surgery for Rhegmatogenous Retinal Detachment [PDF]
, 2008 Scleral buckling surgery significantly increased HOAs. The segmental buckling procedure increased the HOAs to a greater extent and for a longer duration than the encircling procedure.

Changes in forward light scatter parameters as a function of refractive error in young adults [PDF]
, 2020 Background/aims Some aspects of visual performance worsen with increasing myopia. Whilst the underlying causes are not always clear, reduction in retinal image quality is often attributed to structural changes in the posterior myopic eye.
