Can eye drops end this need for reading glasses?

Statistics no Lying: after the age of 65, Most people He will struggle to focus visually on things closely. You may have seen this between your friends and relatives, or even try yourself, or hold books, magazines, or your phone away from your face to try to bring words and pictures to focus. Many of these affected people start using reading glasses. But the new treatment can become available: eye drops.

The deterioration of the vision is called this sheikh. It is not a disease but rather a physiological change from aging – specifically due to the loss of flexibility and flexibility Crystal At the front of the eye, which weakens the eye’s ability to change the curvature of the lens to bring things to focus. This sclerosis begins in middle age and tends to settle at the age of 65. For people with nearsightedness, or nearsightedness, who are struggling to see distant things clearly, the appearance of exercises may lead to vision at the beginning by compensating their current condition. For those who suffer from delayed, or over -control, the effects of the sheikhdom are often present early in the rest of the population.

It can cause livelihood with priests by fatigue and headache, and in rare cases dual vision, but generally not anxiety. But its correction can make daily activities easier and help maintain the quality of good life. The classic method of correction is reading glasses, although people choose ophthalmology in some cases – either laser refractive surgery to reshape the cornea to compensate for losing flexibility in the lens or inside the eye to replace the lens with artificial control. The latter is often proposed when there is also some mystery in the lens (cataracts).

But recently, researchers have been working on eye drops, in various ways depending on the active ingredient used, improving near the concentration. Two types were approved by the American Food and Drug Administration: one depends on a substance called Aceclidine, and the other on Pilocarpine.

Pilocarpine is the stars molecule, with multiple experiences of current new combinations. It is a natural alkaloid that interacts with parts of the nervous system, which has an effect, in an eye, to stimulate miosis – narrowing the student’s diameter – and shrinking the cordial muscles, the muscle loop that controls the shape of the lens. The two common effects improve the flexibility of the lens and the ability to focus on nearby organisms.

accident trial In Argentina, she tested the decrease in the pelocarbin eye with various concentrations (1 percent, 2 percent, 3 percent) in a mixture of diclofenac, which is an anti -inflammatory non -steroid that calms the harmful effects of blockpine such as irritation and discomfort. (Pelocarbin drops approved by FDA are 1.25 percent.

In a retro -impact study of two years of 766 people, an average age of 55 years, researchers found that eye drops enabled the majority of patients to improve their vision. “Our most important results have entered into rapid and sustainable improvements in the near vision of all three concentrations,” said the lead researcher Giovana Benzzi. presentation Research in the conference 43 of the European Association for Air lens and refraction surgeons.
