This polyvalent intervention is possible thanks to the implantation of a multifocal toric intraocular lens. A procedure that, today, is simple but is the result of many years of research and development in the field of ophthalmology.
The doctor. Cabot is an expert in eye problems such as myopia, hyperopia, astigmatism, presbyopia and cataracts. He has dedicated a long time of his investigations in knowing and analyzing the vanguard of his treatments.
The diffractive multifocal toric lens is the latest contribution in the field of refractive surgery and its implementation allows to please all those patients who do not want to wear glasses, neither for far nor to read, and who have a previous corneal astigmatism associated. This technology is aimed at presbyte patients with failure of the intrinsic ability of the young crystalline lens to focus on nearby objects. This usually happens from the age of 45 in emmetropic patients, that is to say without any defect in sight, a little before in hyperopic patients and a little later in myopic patients.
Thanks to its variety and design, the lenses allow to offer different ranges of vision, thus adapting to the physiological peculiarities of each patient and their preferences.. They are lenses with excellent technical characteristics such as bioadhesion to the capsular bag or filter of UV light and blue. All the advantages of multifocal technology, in addition to the correction of astigmatism.
The treatment consists in replacing, by means of a minimally invasive intervention, the non-functional crystalline lens, and therefore without accommodation capacity, by a diffractive permanent intraocular lens, that is, with two image foci, one for distant objects, more than 4 meters away, and another for nearby objects, approximately 40 centimeters.
The exchange of the lens through the toric multifocal lens is done through a 2 mm wide incision that closes spontaneously without any suturing.. At 48 hours the incision is completely sealed. In addition, the procedure is performed without the need for a puncture, only with topical anesthetic. Patients can leave the outpatient clinic by their own feet after 30 minutes of treatment and join their usual activities. The entire process takes just over 2 hours. The risks of this intervention are inherent to any surgical procedure, basically the risk of infection. Although the use of last generation antibiotics minimizes it, it still exists and, therefore, the process requires the proper supervision of properly trained and trained professionals for the task.
