The refractive capacity of the normal eye is 60 diopters: approximately 43 in the cornea, 15 in the lens and the rest in the aqueous and vitreous humours. When there is a problem in the cornea, this loses its capacity of refracting its 43 diopters necessary for focusing the image on the retina and seeing correctly. To make up for this shortage of diopters, it is necessary to wear a false lens, glasses or contact lenses, with the curvature required to restore the original 43 diopters.

When this lens is added, the image is once again refracted and focused on the retina correctly.

TREATMENT THE NEW AMARIS LASER

- LASER AMARIS (LASEK Y LASIK)
- ICL
- INTAC
- MULTIFOCAL MUDDLE

IOTT presents—exclusively in Catalonia—the new AMARIS Laser for refractive surgery operations,
Indicated for use in patients with myopia, astigmatism, eyestrain or hyperopia, visual recovery of 90% is guaranteed in the first 24 hours. manufactured by the company, Oftaltech, in 2007.

This is a much faster, more effective, safer and reliable laser than any other laser on the market. Once again using high technology, the AMARIS is capable of eliminating up to eight dioptres in just a few minutes and without complications. Among its main features, the AMARIS laser offers a pulse frequency of 500Hz, shortening operation times by approximately five minutes per eye.

Furthermore, its improved mechanism gives the surgeon total control of the eye during the operation, allowing for safer, more effective and more personalized operations.

How the laser works?

Laser performs ablation in the deeper layers of the cornea.
80% recovery of vision occurs within 24 hours, 100% being attained in just a few days. It has become the technique of choice, thousands of operations having already been carried out with absolute safety and success.    

Why do we no longer need glasses after laser surgery? 

The laser acts directly on the cornea to restore its curvature of 43 diopters. By restoring its capacity to focus the image perfectly on the retina, it is no longer necessary to wear other lenses, since the eye works correctly by itself. This surgery is called refractive precisely because it restores to the cornea its natural refractive capacity

• ICL

Implantable Contact Lenses, i.e. contact lenses which can be inserted into the eye, are the ideal option for all those patients whose profile does not allow them to receive laser surgery.
The lens, of a very slim appearance, is made of collamer, a very flexible material which is highly compatible with the eye, preventing rejection of the same.

There are lenses for correcting refraction defects of up to 18 diopters of myopia and 10 of hyperopia, as well as those which are ideal for correcting astigmatism.

The simple operation begins about fifteen days before surgery. In the doctor’s surgery, two small, entirely painless perforations are made at the periphery of the iris in order to avoid possible complications. When the fifteen days have elapsed, the lens is implanted in the operating theatre, using an injector which enables it to be placed within the eye without being touched.

This operation lasts approximately ten minutes and is completely reversible. 

• INTAC

Intacs are thin, transparent inlays which are inserted at the periphery of the cornea, highly recommended in slight myopias or in persons with keratoconus, a degenerative disease of the cornea.

They carefully remodel the cornea and restore correct refraction to the eye, without the need to remove tissue or manipulate the interior of the eyeball. Intacs are safe and highly effective.

The simple, totally risk-free operation, consists of a making a small incision in the surface of the cornea, to later insert the intacs: Two layers of the corneal tissue are separated by way of a semicircular tunnel of negligible size, and the intacs are inserted by way of corneal attachment.

The intacs flatten the cornea by exerting a light outward pressure. As a result, light is centred on the retina and clearer, sharper vision is achieved immediately.

Doctor Emilio Juaréz was elected “professor” in the implantation of intacs.

• MULTIFOCAL MUDDLE

They are permanent lenses surgically implanted within the eye to replace the natural lens.
They are used to correct focusing after surgery, such as cataract operations for example, or to eliminate long-sightedness or eyestrain.  

Optical correction is constant and the images seen by both eyes are the same . Intraocular lenses are currently the best method for replacing the lens due to their great reliability thanks to the materials they are made of. Multifocal intraocular lenses offer the patient the chance of having excellent near, far and medium vision at the same time.

The lens of the human eye is equivalent to a 15 diopter lens, such that when an intraocular lens is inserted, care is taken for this to have the same or more diopters than this. They are surgically implanted directly into the eyeball and play the role of the lens, enabling the eye to focus on both near and far objects without the need to use glasses.

Intraocular lenses are implanted in the eye by means of a very simple, fast operation with immediate results. The technique known as microsurgical phacoemulsification consists of aspirating the affected lens and replacing it with the multifocal lens. It is carried out with local anaesthetic, a few drops in each eye, and visual recovery, both far and near, is practically immediate, enabling the person operated to take up his/her daily activities in just two or three days.

What does having diopters mean?

This is called “factory defect”. It is a variation in the refractive power of the different meridians of the cornea, causing distorted eyesight and a blurred image at any distance, rather like in a hall of mirrors in which an object may appear wider, taller or thinner than it really is. This may appear alone or in combination with myopia and hyperopia.
