A study of 104 eyes found that superior-hinged LASIK flaps resulted in reduced corneal sensation and increased dry eye symptoms. The American Academy of Ophthalmology recommends using nasal-hinged flaps to minimize the risk of dry eye complications.
Schepens Eye Research Institute scientists have discovered a new drug that can trap abnormal growth factors in the cornea, potentially improving corneal transplants. Additionally, a gene therapy approach has shown promise in preventing and treating autoimmune diseases like uveitis by inducing a protein called a-MSH.
A new LASIK procedure uses femtosecond lasers to create precise, high-precision cuts in the human cornea, reducing complications and improving reliability. The technology has been safely used in over 30,000 procedures, offering a bladeless alternative to traditional microkeratome-based methods.
Researchers at Cornell University found that the human eye can compensate for certain types of optical faults, such as corneal astigmatism and high-order aberrations. The study used wavefront analysis to measure deviations in the eye's optics and found evidence of internal compensation mechanisms.
The Bio-X program has awarded grants to 21 new interdisciplinary research projects, including the development of an artificial cornea and a wireless gastric endocapsule. These projects aim to boost collaborations among faculty, students, and staff across departments and schools.
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.
UC Davis researchers have successfully restored vision in 10 of 14 patients suffering from severe corneal damage, using a new technique to grow replacement cornea tissue in a laboratory dish. The treatment showed significant improvement in visual acuity, enabling patients to regain their independence.
Researchers found that wearing reverse-geometry gas permeable contact lenses for 7 nights improved the daytime eyesight of 7 out of 8 nearsighted subjects. By the end of a 60-day trial, all subjects could see clearly without contacts or glasses.
Research suggests that REM sleep plays a crucial role in protecting the cornea from suffocation by circulating aqueous humor. This theory challenges the conventional view of REM as a dream-processing mechanism, proposing a new purpose for this stage of sleep.
