This multipurpose procedure is possible thanks to the implantation of a multifocal toric intraocular lens. A procedure that, at present, is simple but is the result of many years of research and development in the field of ophthalmology.
Dr. Cabot is an expert in eye problems such as myopia, hyperopia, astigmatism, presbyopia and cataracts. He has devoted much of his research time to understanding and analyzing the state of the art of their treatments.
The multifocal diffractive toric lens is the latest contribution in the field of refractive surgery and its implementation makes it possible to satisfy all those patients who do not want to wear glasses, neither for distance nor for reading, and who have associated previous corneal astigmatism. This technology is intended for presbyopic patients with failure of the intrinsic ability of the young crystalline lens to focus on near objects. This usually occurs from the age of 45 in emmetropic patients, i.e. without any visual defects, slightly earlier in hyperopic patients and somewhat later in myopic patients.
Thanks to their variety and design, the lenses can 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 UV and blue light filtering. All the advantages of multifocal technology, in addition to astigmatism correction.
The treatment consists of replacing, by means of a minimally invasive intervention, the non-functional crystalline lens, and therefore without accommodation capacity, with a permanent diffractive type intraocular lens, that is to say, with two image foci, one for distant objects, more than 4 meters away, and another for near objects, at approximately 40 centimeters.
The exchange of the crystalline lens for the toric multifocal lens is performed through a 2 mm wide incision that closes spontaneously without the need for sutures. After 48 hours the incision is completely sealed. In addition, the procedure is performed with no need for a needle stick, only topical anesthetic. Patients can leave the outpatient clinic on their own 30 minutes after treatment and return to their normal activities. The whole process takes just over 2 hours. The risks of this intervention are those inherent to any surgical procedure, basically the risk of infection. Although the use of the latest generation of antibiotics minimizes this risk, it still exists and, therefore, the process requires the correct supervision of professionals properly trained and qualified for the task.
