Introduction The incidence of ectasia following refractive surgery is unclear. This review
sought to determine the worldwide rates of ectasia after photorefractive keratectomy (PRK) …

This book describes the optical structure and optical properties of the human eye. For ease
of reference, the most commonly useful topics are at the beginning and topics with narrower …

Strategies such as monitoring inflammatory factors and using immune or inflammatory
modulators, including managing subclinical inflammation, may be clinically beneficial in …

MUCH OF THE INFORMATION in this article—as with previous annual reports—is obtained
from a combination of recent research and polling of both the Contact Lens Spectrum (CLS) …

Purpose: To discuss factors influencing corneal aberrations that might influence the optical
quality after intraocular lens (IOL) implantation. Methods: PubMed and Scopus were the …

Objectives: To evaluate the utility of the SPOT scleral lens (Oxygen Permeable Scleral Lens
of Thonon; LAO, Thonon-les-Bains, France) in the management of the irregular cornea after …

Purpose To investigate the effect of varying the fluid reservoir (FR) thickness of scleral
lenses (SL) on corrected distance visual acuity (CDVA), contrast sensitivity (CS) and higher …

Objective: To compare corneal biomechanics and intraocular pressure (IOP) in keratoconus
and penetrating keratoplasty eyes before and after nonfenestrated scleral lens wear …

Keratoconus (KC) is a complex multifactorial corneal ectatic disorder, with disease onset
commonly in the second-third decades significantly affecting quantity, quality of vision, and …

Purpose The fit and optical performance of a scleral lens is affected by the alignment of the
landing zone with the underlying ocular surface. The aim of this research was to quantify the …
