The aim of this study is to compare the subjective performance of the comfilcon A contact lens against lotrafilcon B contact lens after 4 weeks of reusable lens wear.
The purpose of this trial is to evaluate the factors affecting comfortable contact lens wear and how those factors affect contact lens replacement frequency.
The purpose of this study is to compare visual acuity and redness of eyes between a new contact lens and an already marketed contact lens.
In an effort to improve the comfort of lotrafilcon A subjective responses and lens fit variables will be obtained during 4 weeks of wear of lotrafilcon A upgrade lenses and compared to res...
The primary objective of this trial is to compare the performance of lotrafilcon B to habitual HEMA and SiHy spherical contact lenses in a selected segment of the contact lens wearing popu...
The outermost surface composition of 11 silicone hydrogel (SiHy) lenses was measured using X-ray photoelectron spectroscopy (XPS) to understand differences in wettability and potential interactions wi...
To investigate characteristics of the eyelid margins, meibomian glands and the tear film of contact lens wearers, and to determine whether these characteristics were related to symptoms of contact len...
The purpose of this article is to provide a review of existing literature describing complications with contemporary contact lenses and their management. It is envisioned that this will serve as a use...
Contact lens cases become contaminated with microbes during use. We wished to compare the adhesion of uncommon bacterial contaminants isolated from lens cases to contact lenses with and without organi...
To determine the effects of contact lens (CL) wear on biometry measurements for cataract surgery and whether a CL hiatus can reduce the prediction error of intraocular lens (IOL) calculations.
Sterile solutions used to clean and disinfect contact lenses.
Insertion of an artificial lens to replace the natural CRYSTALLINE LENS after CATARACT EXTRACTION or to supplement the natural lens which is left in place.
Examination of the angle of the anterior chamber of the eye with a specialized optical instrument (gonioscope) or a contact prism lens.
The portion of the crystalline lens surrounding the nucleus and bound anteriorly by the epithelium and posteriorly by the capsule. It contains lens fibers and amorphous, intercellular substance.
Incomplete rupture of the zonule with the displaced lens remaining behind the pupil. In dislocation, or complete rupture, the lens is displaced forward into the anterior chamber or backward into the vitreous body. When congenital, this condition is known as ECTOPIA LENTIS.
