Astigmatism News and Research

RSS

Astigmatism is a type of refractive inaccuracy in which the shape of the normally curved surface of the cornea is curved to different degrees in different areas. As a result of this abnormality, the light rays that enter the eye fails to converge at a focal point and instead comes to a focus at different focal points with a distance between them.

Bausch & Lomb's Lo-Torque- lens design delivers better rotational recovery

Bausch & Lomb today announced that the company's Lo-Torque- lens design demonstrates significantly better rotational recovery, which can lead to more consistent vision, compared with Acuvue's accelerated stabilization design. These findings from two clinical studies were presented at Academy 2009, the American Academy of Optometry annual meeting in Orlando, Fla.

Children who spend more time outdoors are less likely to develop short-sightedness

"The results of this study are consistent with an American study which found that outdoor sport was protective, however our study shows that the crucial feature is being outdoors irrespective of the activity you are doing."

Older children more likely to develop cross-eye and lazy eye

In a study of more than 6,000 Los Angeles-area children – the largest study of its kind – researchers at the Keck School of Medicine of the University of Southern California (USC) found that both strabismus (commonly known as cross-eyed or wall-eyed) and amblyopia (often referred to as lazy eye) were more prevalent in older children than in younger children.

New insights into visual disturbances accompanying skull deformations

Most children with a craniofacial deformity known as unicoronal synostosis have the eye-alignment abnormality strabismus, reports a study in the May Journal of Craniofacial Surgery , published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Custom-designed contacts improve vision for subjects with keratoconic eyes

Keratoconic eyes are rare but disabling. From the side, the eyes look more pointed or cone-shaped than round. The apex shift from visual axis in the cornea causes people with the condition to see halos and double and triple images. About 1 in 2,000 people suffer from the disease, usually in both eyes.

LASIK for patients 40-69 years old

A new University of Illinois at Chicago study appearing in the online edition of the journal Ophthalmology reports on the safety, efficacy and predictability of laser eye surgery (laser in situ keratomileusis or LASIK) in patients 40-69 years old.

Ophthalmologists improve LASIK

Ophthalmologists have developed a formula that slashes by nearly two-thirds the likelihood that patients will need repeat visits to an eye surgeon to adjust their vision after their initial LASIK visit. That's because the formula makes it more likely that surgeons will get it right the first time.

Bladeless LASIK as good as standard microkeratome LASIK

A Mayo Clinic study comparing femtosecond (bladeless) and mechanical microkeratome LASIK surgeries has found equal results from both types six months post-surgery, using a variety of vision and eye health measurements.

Researchers characterize the proteome of the human cornea

In doing so, they have identified 141 distinct proteins, 99 of which had not been previously recognized in mammalian corneas. The details of their findings appear in the August/September issue of Molecular and Cellular Proteomics, an American Society for Biochemistry and Molecular Biology journal.

Laser refractive surgery is a safe, effective way to correct myopia, hyperopia and astigmatism

Hopkins researchers have found that patients experiencing vision problems following cataract removal and intraocular lens implantation (CE-IOL) may have better results from laser refractive surgery, which spares them potential complications of lens implant replacement and the inconvenience of glasses.

Confusion over Lasik eye surgery terminology

The Eye Surgery Education Council of the American Society of Cataract and Refractive Surgery Foundation today issued a clarification on the use of the terms "wavefront-guided," and "wavefront-optimized" in connection with laser-based procedures (LASIK, PRK, etc.) and implantable lenses used for vision correction purposes.
