It consists of the modification of the shape of the cornea to change its power or total graduation of the eye. To do this, the epithelium (thin and superficial layer) must be carefully separated from the cornea, either mechanically or with the extremely precise FEMTOSECOND LASER, and then apply the excimer laser that models the cornea to correct the desired diopters. Finally, the area treated with the epithelium is covered, previously separated, without the need for suture, to restore the standard eye surface. Currently, the excimer laser allows personalized treatments to increase the accuracy of the correction and the quality of vision in special situations such as night vision, while respecting more efficiently the thickness of the cornea. Laser surgery is performed with topical anesthesia (anesthetic drops) in a few minutes and tends to restore vision in a few hours, so that the patient can often perform most of his usual activities the day after the operation without the necessity to use optical correction.
When defining refractive surgery, the most important factors to consider are the magnitude of these defects, the characteristics of the eye to be treated and the age of the patient. In young patients with moderate to severe defects and with a thin cornea, the most appropriate technique is one that uses phakic lenses (no need to remove the lens) such as the ICL. This intraocular lens was designed for the correction of myopia or hyperopia in young patients, and allows them to retain the ability to see closely without correction since it does not replace the natural lens. Our experience with this Premium lens dates back to 1993, when Dr. Roberto Zaldivar became one of the main surgeons involved in the development not only of the ICL lens but of its implantation technique. Thanks to this scientific merit, Dr. Roberto Zaldivar constantly receives international recognition.
It consists of the extraction of the opacified lens and its replacement by an artificial one (intraocular implant) that is placed in the same place of the lens allowing the person, in most cases, to recover the lost vision. The operation is usually performed under local anesthesia and is ambulatory; that is, the patient returns home the same day of the intervention.
The surgery is reversible, that is, the rings can be completely removed or exchanged for a different size. The tunnel inside the cornea is performed with a FEMTOSECOND laser that is programmed according to each patient, that is, it is a personalized treatment. The laser procedure per eye lasts 7 to 10 seconds, depending on the parameters used. After the laser the rings are placed inside the tunnel.
Transplantation of a healthy donor endothelium (DSAEK). It is possible to place a new cell layer on the back of the cornea that, when correctly performing its biological functions, returns transparency to the corneal tissue in most cases.
To be able to see, the light has to pass through the vitreous to the retina. Sometimes, the light cannot pass because the vitreous is cloudy due to the presence of blood, inflammation or infection, and in other cases the retina may be damaged, for example, in a retinal detachment. By removing the vitreous you can eliminate these problems or you can have better access for retinal repair.
These drugs are injected inside the eye, into a chamber located in the back of the eye, in front of the retina, called the vitreous cavity, occupied by a jelly called vitreous humour. This injection is performed under strict aseptic conditions, equivalent to those of an eye surgery. To do this, drops of a powerful bactericide (iodopovidone) are instilled on the surface of the eye. Currently, in many cases, after 3 initial monthly injections, "of attack", intravitreal injections are repeated according to the results of the controls.
The treatment only lasts a few minutes. It is not invasive, it is ambulatory, it does not hurt and does not require anesthesia. The patient is comfortably seated in a treatment chair. The specialist puts eye protection glasses and gel in the region of the cheekbones to be treated. A sequence of flashes is performed on the skin of one cheekbone and then the other. Manual expression of the Meibomian glands is performed.
The treatment only lasts a few minutes. It is not invasive, it is ambulatory and it does not hurt. "The patient" is comfortably seated in a treatment chair. The specialist puts a drop of topical anesthesia on each eye. Heat and local compression is applied to the eyelids of each eye to be treated. The mechanical expression of the Meibomian glands is performed.
