ICL lenses are the most effective alternative for the treatment of myopia, astigmatism and hyperopia where Lasik is not indicated: dry eyes, large pupils, reduced corneal thickness, alterations of corneal morphology.
The ICL lenses are made of Colamer, a substance perfectly tolerated by the eye and are soft and small so they can be injected into the eye without pain, in just a few seconds, through a very small incision in the cornea.
Once the ICL lens is injected, it is placed and adjusted in its position in front of the lens and behind the iris. Once inside the eye, the lens is invisible and is not felt at all.
The ICL lens is designed to remain indefinitely in the eye. The advantage is that it can be removed when needed as it does not damage the structures of the eye.
That is all! The entrance has no stitches, it is sealed in a natural and healthy way in a very short time.
The implantation of an ICL is considered an outpatient basis surgery and lasts about 15 minutes per eye. A few hours after the surgery, the patient can leave the clinic and return to his or her activities.
ICL lenses can correct most refractive errors when Lasik is not indicated.
Myopia and / or severe astigmatism.
Alterations of corneal morphology.
Through a small 3 millimetre incision made at the edge of the cornea we introduce a small applicator through which the lens is injected. Once inside the eye, the lens opens and is placed either in the anterior chamber or in the posterior ocular chamber. Once the implant is done, the incision is sealed without the need for stitches.
For the placement of the lens, we use local anesthesia. The intervention does not hurt and the patient returns home after the operation, keeping the eye covered until the following morning.
In cases where myopia or hyperopia coincides with astigmatism, the implantation of the lens can be complemented with the subsequent laser application, obtaining amazing precision results.
Severe Myopia And Hyperopia Surgery: Candidates
Current surgical techniques with excimer laser are limited by the thickness of the cornea (which, under normal conditions, is about 500 microns) and other factors such as corneal and pupillary parameters.
With this system up to approximately 10 dioptres of myopia and 6 of astigmatism or hyperopia can usually be removed.
When the prescriptions are higher than these, a result with the desired quality of vision is not usually achieved with the laser.
There are cases in which, either by excessive dioptres, or by having an excessively thin cornea, or by other less usual causes, the limits of the laser are exceeded. In these cases intraocular lenses are used as a solution of great precision and with which a great quality of vision is gained.
Almost all cases of myopia and hyperopia (even with few dioptres), in which previous ophthalmological examination ruled out the existence of any ocular pathology, are candidates for this technique, however in Eye Clinic Dr. Tirado we normally reserve its use for severe prescriptions.
SEVERE MYOPIA AND HYPEROPIA SURGERY: INTRAOCULAR TRANSPLANT
The intraocular lenses are made of acrylic inert materials which are perfectly tolerated by the body and do not produce any rejection.
There are different types of intraocular lenses. Both the lens design and its positioning in the eye vary.
Therefore, there are posterior chamber lenses, which are placed behind the pupil, and anterior chamber lenses that are placed in front.
According to the characteristics of each eye and applying previous tests (ultrasonic measurement of the parameters of the eye, count of endothelial cells, etc.), the surgeon decides the most appropriate lens for each case.
