For over some decades ophthalmologists have been treating presbyopia with drugs with the aim of stopping it and helping patients to recover their vision.

The simplest non invasive treatment consists of using drops which give the eye back its aptitude to focus, the same way we could do when we were young without the need of glasses.

This medicine is obtained from a medicinal plant which was used by the aborigines of the north of Brazil before colonization.

The great majority of the patients who begin this treatment manage to drive, work, read, use the computer and write text messages without the need of glasses.

Due to the rising requirements of our society in general and of technological advances in particular, we have observed an increase in the demand of solutions to improve and preserve vision over the last years.

Our recommendation is to use preventive treatments which are neither invasive nor risky and to pay attention to some simple habits such as: being moderate with muscle relaxants and psychoactive drugs (sedatives and tranquilizers), wearing glasses for presbyopia as little as possible, reading using good quality light (if possible solar or incandescent) and avoiding wearing glasses while walking, including either bifocals or multifocals.

Preventive treatment

Successful research has been carried out for over the past decades on presbyopia and hyperopia treatment and some diseases of the accommodation and refraction of the eye.

As a result, significant progress has been made in the knowledge and treatment of diseases of the visual system (related to genetic influence as in the case of hyperopia or caused by aging as presbyopia) allowing to reduce or to stop the advancement of the loss of vision in a great number of people.

The preventive treatment is drug based. It has been used in research for over thirty years and at present is administered combining drugs.

It is a very simple method and it is the most appropriate one for those willing to stop wearing glasses.

The composition and dosage varies according to each particular case and is administered following medical evaluation.

In short, the idea is to find the solution for presbyopia and to preserve a good quality of vision during our entire life, which is both the wish of our patients and what is expected from us.


Hyperopia, also known as farsightedness, longsightedness or hypermetropia, is a defect of vision caused by an imperfection in the eye refraction which affects about 10 percent of population.

Hyperopia develops in eyes that focus images behind the retina instead of on the retina, which can result in blurred vision.

This occurs when the eyeball is too short, which prevents incoming light from focusing directly on the retina. It may also be caused by an abnormal shape of the cornea or lens.

Farsightedness often starts in early childhood. But normal growth corrects the problem. If a child is still a bit farsighted when the eye has stopped growing (at around 9 years of age), the eye can usually adjust to make up for the problem. This allows the child to see clearly. But as we age, our eyes can no longer adjust as well, and farsightedness becomes more obvious.

Symptoms and clasification:

Young people with mild to moderate hyperopia are often able to see clearly because their natural lens can adjust, or accommodate to increase the eye’s focusing ability. However, as the eye gradually loses the ability to accommodate (beginning at about 40 years of age), blurred vision from hyperopia often becomes more apparent.

Symptoms depend on the degree of hyperopia. Some individuals may have no symptoms, while others have blurry near vision and clear distance vision, and those with the most severe cases have blurry near and distance vision. Headaches and eyestrain may also occur, particularly when doing close work.

People with hyperopia can experience blurred vision, asthenopia, accommodative dysfunction, binocular dysfunction, amblyopia, and strabismus.

Hyperopia is typically classified according to clinical appearance, its severity, or how it relates to the eye's accommodative status.

Various eye care professionals, including ophthalmologists, optometrists, orthoptists, and opticians, are involved in the treatment and management of hyperopia.

There is already a variety of existing methods, some drug based, others optical and surgical. All of them are used efficiently meeting the requirements of the different stages of the eye disorder, both prematurely working with prevention and later with recovery of the vision.

Minor amounts of hyperopia are sometimes left uncorrected. However, larger amounts may be corrected with convex lenses in eyeglasses or contact lenses. Convex lenses have a positive dioptric value, which causes the light to focus closer than its normal range.

Hyperopia is sometimes correctable with various refractive surgery procedures;LASIK or conductive keratoplasty. It can also be corrected with implanted special concave lenses.

Moreover, the benefits of this treatment are to avoid both the dependence on glasses and the rebound effect of glasses, to improve close and far vision and to recover or avoid blurred vision caused by some medicaments such as muscle relaxants and psychoactive drugs (sedatives and tranquilizers).

Thus, this treatment provides the great majority of its users the satisfaction of maintaining their vision in spite of years going by. And a great number of people who could only see properly wearing glasses or contact lenses can improve their vision significantly.

As regards present treatments which are optical or surgical, the administration of this medicament is helpful since it avoids progressive changes in the adjustment of glasses and prevents relapse of hyperopia in the post operation period.

As a preventive method, its efficacy varies according to the patient’s age when starting the treatment.

Its strongest effect is between thirty five and sixty nine years old.

It can be administered among children and youngsters as well.

The duration of the treatment is optional and it depends on each individual; it can even be continued for a lifetime.

Stopping the treatment does not have unwanted effects and it is observed that the vision returns to the level at the starting point, according to the patient’s age and previous refraction.

In very few cases has the treatment been cancelled due to adverse effects such as allergic reactions in the conjunctiva or cephalea in hyperreactive patients.

Scientific base principles:

The ciliary muscle controls the shape of the lens through suspended suspensory ligaments called zonules. This provides the acomodation ability to the eye.

Like most smooth muscles, the ciliary muscle has a dual innervation, receiving both sympathetic and parasympathetic fibers.

In the ciliary muscle, the contraction necessary for accommodation is under parasympathetic control.

Most current theories of accommodation assume that the condition of physiological rest of accommodation occurs when the emmetropic eye focuses on a distant target, demanding good resolution.

Accordingly, in the natural resting state of the eye, the parasympathetic system maintains ciliary muscle tone, i.e., the ciliary muscle is contracted and zonular tension is relaxed such that the lens is more spherical and in a forward position increasing the refractive power of the eye. Thus, the eye is naturally in a “tonic accommodative” state and with appropriate stimulus is capable of further active positive accommodation.

Aging studies on the brain have demonstrated a loss of function of the parasympathetic system that is due to a decline in the neurotransmitter substance acetylcholine. This is probably due to a decreased production by the enzyme cholineacetyl transferate (CHAT) acetylcholine synthetase as there is no decline in parasympathetic receptor cells with age. That is, the ciliary muscle has the same number of receptors and the contractile ability of the muscle is the same in young and old individuals.

The administration of the lacking neurotransmitter or muscarinic agonist may restore the lost vision.

This compounds are known in the art for their purposes, and are known to be safe under ordinary conditions of use.

Thus, the treatment can be administered by substantially conventional means, consistent with known eye treatments, and while avoiding irritation, discomfort or the need of unusual application procedures.
