CONTACT LENS CARE & COMPLIANCE
Article IN-OFFICE CONTACT LENS DISINFECTION By MELISSA BARNETT, OD January 1, 2020 For those of us in clinical practice, the use of diagnostic, or trial, contact lenses is customary. These must be disinfected prior to storage and use on another patient. Contact lens practitioners face the threat of transferring potential pathogens from one patient to another when reusing diagnostic contact lenses on multiple patients in practice.
THE ROLE OF THE OCULAR SURFACE IN CONTACT LENS WEAR
Reducing contact lens dropout rates has always been a goal, and often a challenge, for even the best contact lens practitioners. The primary reasons why patients discontinue contact lens wear are poor vision and reduced comfort.
CONTACT LENS CARE & COMPLIANCE
Article A CLOSER LOOK AT POLYHEXAMETHYLENE BIGUANIDE By MELISSA BARNETT, OD November 1, 2019 Polyhexamethylene biguanide (PHMB) is a broad-spectrum antimicrobial biocide used as a disinfectant and antiseptic. PHMB is efficacious against gram-positive and gram-negative bacteria including methicillin-resistant Staphylococcus aureus (MRSA) (Müller and Kramer, 2008), fungi, parasites, Aspergillus brasiliensis (mold), and certain viruses.
CONTACT LENS CARE & COMPLIANCE
Article THE IMPORTANCE OF A LENS CARE SOLUTION PRESCRIPTION By MELISSA BARNETT, OD September 1, 2019 According to Merriam-Webster’s dictionary, the word prescribe comes from the Latin word praescribere, which means to write at the beginning, dictate, or order. How does this relate to contact lens care solutions? A myriad of contact lens complications can occur due to misusing a recommended care solution or to using a non-prescribed care solution.
Contact Lens Care & Compliance: Hydrogen Peroxide and the Ocular Surface
Because vision and comfort with contact lenses are intertwined, having a pristine ocular surface may not only enhance lens comfort, vision may also improve. Rao and Simpson (2016) established that there is an association between clarity of vision and ocular comfort. Vision under blurred conditions for both spatial blur and dioptric defocus was graded significantly different (p < 0.001) from clear viewing conditions (Rao and Simpson, 2016).
Product Focus: Experiences with Bruder's Eyeleve Compress
Bruder Healthcare offers the Eyeleve Contact Lens Compress, which the company says delivers consistent, therapeutic moist heat that alleviates symptoms of meibomian gland dysfunction and contact lens-related dry eye. The Eyeleve Contact Lens Compress utilizes silver ion MediBeads that retain moisture naturally and deliver clean, moist heat, according to Bruder. In addition, the company says that the beads will not break down, even when washed.
Assess Scleral Lens Fits
More than 60% of respondents to the 2018 GP Annual Report indicated that scleral lenses have increased slightly, and almost 20% of respondents reported that scleral lens fitting has increased greatly.1 This growth makes sense, when one considers the myriad indications for scleral lenses: ocular surface rehabilitation in severe ocular surface disease, vision improvement by correcting corneal irregularities from corneal ectasias, recovery following corneal surgery and, most recently,...
CONTACT LENS CARE & COMPLIANCE
Article COMPLIANCE WITH COSMETIC CONTACT LENSES By MELISSA BARNETT, OD May 1, 2019 Cosmetic contact lenses were originally designed for people who had disfiguring abnormalities of the iris and cornea; they are now also regularly worn by people who have normal, healthy eyes for cosmetic transformation (Abdelkader, 2014; Singh et al, 2012). Decorative lenses, like contact lenses prescribed for vision correction, are classified by the U.S. Food and Drug Administration (FDA) as medical devices.
Contact Lens Spectrum - The Laboratory Consultants
Whenever you make a major purchase (for example, to construct a home), do you simply think: “I know exactly what I want, how to design it, where to build it, and what furniture and appliances would be optimum”? Similarly, what if you or a loved one develops a systemic health condition that will require frequent monitoring from an appropriate medical specialist? Would you simply throw a bunch of names against the wall and see which one sticks? We didn’t think so.
Contact Lens Care & Compliance: New Kid on the Block
A disinfection solution needs to be safe and effective, kill pathogens associated with eye infections, have minimal side effects, and be cost effective. Infection due to contact lenses may occur from bacteria, fungi, viruses, parasites, or amoebae. The most common methods of GP disinfection are hydrogen peroxide or polyhexamethylene biguanide, either alone or in combination with chlorhexidine (Choy et al, 2013). The hydrogen peroxide disinfecting process loosens dirt, debris, protein, and deposits.
Clinical Controversies: Myopia Management
For the sixth consecutive year, the American Optometric Association (AOA) Contact Lens & Cornea Section (CLCS) presented a two-hour course on the topic of “Clinical Controversies” at Optometry’s Meeting, which took place in June in Denver. The focus of the 2018 Clinical Controversies program was two-fold: 1) Myopia Management, and 2) Controversies in Advocacy. The latter topic, presented by CLCS Past Chair Dr. Jeff Sonsino, will be published as a separate article.
Contact Lens Care & Compliance: The Importance of Hand Hygiene
Article THE IMPORTANCE OF HAND HYGIENE By MELISSA BARNETT, OD January 1, 2019 Did you know that only 5% of people wash their hands correctly? According to a study of 3,749 people in a college environment, the majority of people do not wash their hands as recommended by the Centers for Disease Control and Prevention (CDC) (Borchgrevink et al, 2013).
CLINICAL CONTROVERSIES: PRESBYOPIA CORRECTION
For the fifth consecutive year, the American Optometric Association (AOA) Contact Lens & Cornea Section (CLCS) presented a two-hour course on the topic of clinical controversies at Optometry’s Meeting, which was most recently held from June 21 to 25, 2017 in Washington, DC.
