Eye care professionals are adopting wavefront optics to correct subtle visual issues and monitor eye health. The technique, inspired by astronomy, offers new tools for assessing and correcting higher-order aberrations in the eye.
A study found that using well-designed tools to assess patient-reported outcomes can lead to new insights for improving cataract care. Patient-reported measures were affected by clinical measures such as visual acuity and ocular comorbidity, but also by factors related to better or worse patient-reported outcomes.
A study identifies three advanced optical measures that predict faster age-related declines in visual acuity, including wavefront error and lens clouding. These metrics may help detect patients at risk before their vision loss occurs.
A study by Dr. Susana T.L. Chung reveals that the visual system of older adults with central vision loss is still plastic and can be modified through experiences. Perceptual learning techniques targeting the preferred retinal location led to an average 50 percent increase in reading speed, improving daily functioning.
A study published in Optometry and Vision Science found that changing lens type or lens care product can bring relief to about half of patients experiencing discomfort with contact lenses. The study ranked different combinations, with one showing significant improvement in ocular comfort and symptoms.
A new study found that wearing OK contact lenses every night can restore age-related loss of near vision, allowing patients to read and perform up-close tasks without bifocals or reading glasses. The technique is safe and reversible, with the cornea returning to its previous shape after stopping lens wear.
Three University of Houston optometry educators, all UHCO graduates, received top honors from the Texas Optometric Association. Kevin Gee assumed TOA presidency, Nancy George received the William D. Pittman Leadership Award, and Pat Segu was awarded Educator of the Year.
Researchers found that OK lenses primarily reshape the front of the cornea to correct myopia. After a 14-day treatment period, the changes were significant and vision improved substantially.
A study published in Optometry and Vision Science found high rates of vision problems in both military and civilian patients with TBI, including difficulty reading and light sensitivity. Comprehensive eye examinations are recommended following even mild traumatic brain injury.
A study found that individuals with age-related macular degeneration exhibit decreased focus on internal facial features, leading to difficulty in recognizing faces. The researchers used optical coherence tomography/scanning laser ophthalmoscopy to examine the interior of the eye in nine patients with AMD.
A study published in Optometry and Vision Science found that replacing extended-wear/continuous-wear contact lenses in the morning reduces overall adverse event rates by about four percent compared to nightly replacement. Morning lens replacement also significantly lowers mechanical adverse events, such as corneal scratches.
A simple test of eyelid sensitivity may help vision professionals evaluate one of the most common eye-related symptoms: dry eyes. Researchers found that increased lower lid sensitivity is related to hyperosmolarity of the tear film, suggesting a potential new approach to assessing tear osmolarity via lower lid sensitivity measures.

The research aims to enhance clinicians' understanding of glaucoma development and progression, leading to earlier recognition of structural damage and improved diagnostics.
A simple finger prick test during routine eye exams at high street opticians can identify millions of people with undiagnosed Type 2 diabetes. This could lead to better disease management and cost savings for the NHS.
A recent study by Dr. David C. Musch found that most eye care providers test visual acuity and peripheral vision but often fail to ask about other factors affecting driving ability, such as medical conditions or medications. Eye care providers identify a need for better guidelines and resources to assess driving capabilities.
Earl Smith, University of Houston's Dean of Optometry, has developed a treatment strategy to slow the progression of myopia in children. His team is partnering with researchers in Australia to develop new contact lenses that can be used to implement these strategies.
William R. Baldwin, O.D., was inducted into the National Optometry Hall of Fame for his contributions to the field of optometry. He led the University of Houston's College of Optometry and took steps towards becoming a recognized vision research center.
Ronald S. Harwerth, a world-class glaucoma researcher, has received the 2011 Esther Farfel Award for his outstanding contributions to visual sciences. His work on diagnosing initial stages of glaucoma and binocular vision has earned him recognition as one of the premier visual scientists.
Smith's breakthrough discovery involves new technologies to control myopia progression through peripheral optics manipulation, which can slow disease progression and mitigate vision loss. His work aims to provide practical implications for clinical management of myopia and offers a fundamental shift in optical interventions.
A new study shows that using a more expensive but accurate tool to test for glaucoma can reduce unnecessary referrals by nearly two thirds. This could alleviate pressure on hospitals and lower costs for patients.
Researchers found that low-level lead exposure during gestation increases retinal progenitor cell proliferation and rod photoreceptor and bipolar cell neurogenesis in mice. This discovery could potentially treat retinal degenerations and blindness by transforming human embryonic retinal stem cells into neurons.
Researchers found a new training method to reduce sensory eye dominance by making the weak eye work while suppressing vision in the strong eye. This approach improves depth perception and may be beneficial for professions that require fine depth perception, such as dentists and surgeons.
A new study published in Brain Injury found that traumatic brain injury can cause olfactory loss in patients, with frontal lesions more likely to result in impaired sense of smell. The study recruited 49 people with TBI and found that 55% had an impaired sense of smell.

Researchers at the University of Houston's College of Optometry have developed custom contact lenses to address the needs of patients with eye diseases that affect focus. The lenses correct higher-order aberrations, providing improved vision and quality of life. Early-stage patients have shown dramatic results, and the team aims to mak...
Research shows in-clinic therapy and at-home reinforcement are more effective than home-based programs in treating convergence insufficiency, a condition that affects students' performance in school.
A recent study found that children as young as 8 years old who wear contact lenses have improved perceptions of their physical appearance, athletic competitiveness, and social acceptance compared to those wearing glasses. The researchers suggest that nearsighted children should be given the option to select contact lenses over glasses.
A study found that young children tend to associate glasses with intelligence and honesty, but not attractiveness. The findings suggest that media portrayals may be reinforcing stereotypes among young children.
Research from Cardiff University finds that a third of Down's syndrome children who wear bifocals can switch to ordinary glasses within two years. The study, led by Dr Maggie Woodhouse, reveals that bifocals may be 'teaching' children with the condition to use their own focusing ability.
A recent study found that individuals who purchase contact lenses online are less likely to follow FDA-recommended eye care practices. Online purchasers are also more likely to experience discomfort and vision problems due to incorrect prescriptions.

A recent study by Ohio State University found that almost one in 13 soft contact lens wearers develop severe corneal abrasions, leading to infections or other problems. The study suggests that optometrists monitor their patients for such abrasions and proper hygiene habits can prevent them.
A new study from Ohio State University found that nearly a quarter of LASIK patients experience nighttime vision problems, including halos, starbursts, and glare. These symptoms may persist long after the eye heals and are linked to factors such as having had the surgery repeated or having flatter corneas at the outset.
A study of 50 patients found that almost twice as many preferred disposable extended-wear lenses due to their convenience. The subjects reported no differences in vision, comfort, or eye health between the two types of lenses.
