Gas-permeable lenses "can help keratoconus patients"

Gas-permeable lenses "can help keratoconus patients"

A new type of contact lenses may be effective in improving vision in people who cannot usually wear them, according to a new study.

A report published by the French Society of Ophthalmology claims that gas-permeable scleral contact lenses could benefit keratoconus patients who are intolerant of traditional rigid lenses, along with people suffering from ocular surface diseases, OSN reports.

According to the experts, the larger lenses, which range from 17 mm to 23 mm in diameter, are filled with balanced salt solution and are placed on the eye by using a suction cup.

Dr Benedicte Brousseau, author of the study, commented: "Patients need some time to learn how to use them and also some time to adapt to them, but they are well-tolerated and definitely improve vision as well as the life quality of the patient."

Recently, specialists at Moorfields Eye Hospital NHS Foundation Trust in London claimed that new technique for correcting short-sightedness may be more effective than laser eye surgery.
