EYE-RUBBING AND CONTACT LENSES

Bilateral anterior chamber intraocular lenses dislocation in a patient with habitual eye rubbing.

A 61-year-old Chinese man presented with bilateral posteriorly dislocated anterior chamber intraocular lenses (AC IOLs) one year after successful vitrectomy, removal of bilateral dislocated mature cataractous lenses and AC IOLs implantation. A thorough clinical evaluation revealed habitual eye rubbing as the only possible cause.

Release of Moxifloxacin from Contact Lenses Using an In Vitro Eye Model: Impact of Artificial Tear Fluid Composition and Mechanical Rubbing

PURPOSE The aim of this study was to evaluate and compare the release of moxifloxacin from a variety of daily disposable (DD) contact lenses (CLs) under various conditions using a novel in vitro eye model. METHODS Four commercially available DD conventional hydrogel (CH) CLs (nelfilcon A, omafilcon A, etafilcon A, and ocufilcon B) and three silicone hydrogel (SH) CLs (somofilcon A, narafilcon...

Corneal Sensitivity and Contact Lenses.

IT is a matter of experience that certain persons adjust well to contact lenses while others do not, despite perfect fitting. This adjustment is greatly facilitated if the sensitivity of the cornea is decreased, as it is after cataract extraction. One is therefore tempted to consider corneal sensitivity as a determining factor for the success of a fitting. Previous investigation of the subject ...

Corneal vascularisation and contact lenses.

EDITORIAL The cornea is avascular for the simple reason that to be otherwise would compromise its role as the primary refracting surface of the eye. As a result, situations that may cause vascularisation of this beautifully transparent tissue are energetically avoided. Visual disturbance caused by vascular encroachment upon the central cornea region is, perhaps, the most obvious threat. However...
