It is estimated that over 25 million people in the U.S. suffer from dry eye to one degree or another. Some $3.8 billion annually is spent on various forms of [...]

But that's good news for your astigmatic patients who otherwise must live with over-or undercorrected vision. Does this scenario sound familiar? A 34-year-old female patient with a strong desire to [...]

This doctor's approach acknowledges there are more options than ever, and they're easier for you to fit, too. You're about to prescribe correction for a patient with 0.75D to 1.00D [...]

The article offers information on the second annual Current, Relevant, Useful (CRU) Eye Symposium to be held at Silverado Resort in Napa Valley, California on November 10-12, 2023.

The article discusses the highlights of the inaugural International Keratoconus Academy (IKA) Keratoconus Symposium held in Scottsdale, Arizona in 2023. Topics covered include the goal and mission of the symposium, how the special populations with keratoconus were addressed and the outcome of the symposium.

Steady-state visual evoked potentials (VEPs) in response to contrast reversed vertical grating patterns and uniformly flickering fields were recorded in patients with glaucoma and in controls. In steady-state VEPs, response to temporal and spatial aspects of visual stimuli are combined, which makes the assessment of visual function dependent on their interaction. Fourier analysis of pattern reversal VEP waveforms showed marked deficits in temporal processing of spatial contrast for glaucoma patients. The degree of glaucomatous damage, as manifested by greater optic nerve atrophy and visual field loss, was correlated with progressive disruption of the VEP waveform and progressive failure in temporal processing of spatial contrast progressive patterns. The VEPs in response to uniform full-field flicker showed no deficit.

The plasma leptin concentration adjusted for fat mass is affected by mutant gene dosage in older animals segregating for Lepr^fa. Because the plasma of neonatal rats contains leptin, although their adipocytes contain virtually no triglyceride, we determined whether mutation dose-dependent differences in plasma leptin concentration exist before the postnatal onset of triglyceride storage. Plasma samples were obtained 10 min after birth of each rat pup and leptin concentration determined by radioimmunoassay. Plasma leptin in homozygous wild-type (+/+) pups was 1.60.2 ng/ml (n=20) and 2.40.2 ng/ml in +/fa (n=32) littermates (least-square meansSE, P<0.05, two-way ANOVA with litter and genotype as factors). The corresponding values for +/fa (n=21) and fa/fa (n=15) littermates were 2.40.2 and. 4.00.3 ng/ml respectively (P<0.001). Lepr^fa gene dose-dependent elevations in plasma leptin are, therefore, present at birth and constitute the only Lepr^fa-related phenotypic trait presently known to precede the onset of increased fat storage.

The article reports on the advantages and disadvantages that are associated with soft toric contact lenses and discusses factors which eye care professionals need to consider when attempting to successfully choose and fit soft toric contact lenses in their patients. Reasons that eye care professional often give for not wanting to prescribe soft toric lenses are discussed.

The article discusses advanced technologies that can aid in contact lenses fitting. Advanced technologies such as corneal topography, corneal Scheimpflug imaging tomography and anterior segment optical coherence tomography (OCT) can reportedly measure corneal and anterior segment anatomy and allow virtual contact lens fittings. Focus is also given on software options for contact lens fitting including Medmont E300 Software, Oculus Contact Lens Fitting Software, and Corneal Reshaping Software.

The article introduces new concepts in combination lens designs (CLD) that enable contact lens practitioners to offer gas permeable (GP) optics with soft lens comfort. It provides a working model for fitting patients with hybrid lenses and with the newer soft-GP combination lenses. It also explores the benefits of CLD particularly in solving problems associated with vision and CL complications.

The article offers information on the new discoveries and advancement that are beneficial for the practitioners ability to diagnose, measure and manage patients suffering from corneal irregularities. It discusses several categories of advanced technology which includes, topography, aberrometry and optical coherence tomography.

The article focuses on how to manage patients with dry eye symptoms linked with contact lens through the use of several over the counter (OTC) tear agents products. It says that patients must have a stable tear film to avoid bacterial infection and to ensure enough oxygen transmission. It also says that artificial tears increase patient's performance and contact lens tolerance. It mentions several OTC products including Systane Balance, Soothe XP, and Oasis Tear Products.

The article discusses a study on the qualities of some of the most commonly used contact lens solutions and how their use may affect contact lens-wearing patient. Eye care practitioners are advised to instruct their patients to read the ingredients label of private label solutions. It cites the lubricants and surfactants that keep lenses lubricated and contribute to keeping them clean. It also suggests discussing with the patients why a particular solution was chosen.

The article discusses the advanced technologies with the greatest impact in contact lens practices such as Pentacam corneal topography, Konan specular microscopy system and Oculus Keratograph Topography System. The Pentacam corneal topography utilizes a 360-degree Scheimpflug imaging to deliver true elevation data of the anterior and posterior corneal surface. The Konan specular microscopy system is used as a screening procedure for all contact lens patients. The Oculus Keratograph Topography System helps in the assessment of tear miniscus height.

The article discusses the top reasons for contact lens wear discontinuation and suggests ways for successfully addressing them. The number one reason for contact lens wear dropout is contact lens-related dryness and its associated discomfort. Another is discomfort, which prompts patients to undergo refractive surgery. The poor state of the U.S. economy also dissuades patients to continue wearing contact lens. Dry eye testing and emphasizing the benefits of savings of contact lenses are recommended.

The article shows how contact lens practitioners can point out the differences between soft and rigid contact lens models for multifocal fittings that can suit their patients. It lists out the ways of how practitioners can test the multifocal lenses for their patients, such as putting the contact lens in front of the patient's pupil and selecting the best design, selecting the add prescription, and noting the problems associated with contact lens types and designs.

The article discusses a study that examined the performance of the SynergEyes A lens design when used for a prolonged period of time with different lens care systems. SynergEyes A lenses are said to be hybrid contact lenses composed of a Gas Permeable center made from Paragon HDS. In the study, four care systems were evaluated including Clear Care, ReNu MultiPlus and Aquify. The results of the study showed that selecting the appropriate lens care system is essential for greatest lens comfort, optimal lens movement, and best vision clarity.

The article offers information on the alternative approach for the management of fitting hybrid contact lenses with Multifocal designs and SynergEyes A. It mentions that the hybrid contact lenses fitting should be based on various factors such as corneal diameter data, keratometric, and refractive. It states that the alternative fitting approach of hybrid contact lenses includes skirt curve and proper base curve which address inflammatory ocular and seal-off problems.
