The cornea-based correction technique Intracor is an effective means of improving sight in people with near vision problems, it has been claimed.
This technology applies femtosecond laser energy pulses inside the cornea but does not involve removing cells, making it a reliable alternative to other means of laser surgery, according to Dr Mike Holzer, from University of Heidelberg, Germany.
A study led by the expert found that 25 patients showed "significant gains" in near vision without glasses and maintained good distance vision after undergoing Intracor treatment.
Dr Holzer explained that the procedure is painless and because no tissue is removed, the risk of infection is very low.
"The cornea is not weakened, as it can be with other types of refractive surgery. Patients' vision improved within hours of the procedure and remained stable over the follow-up period," he noted.
In other research, a new study by experts from the American Academy of Ophthalmology found that beta carotene can help to improve vision in people suffering from the retinal disease retinitis pigmentosa.
