Implants for High Myopia and Hyperopia Lenses
ICL lenses
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 in corneal morphology.
ICL lenses are made of Colamer, a substance perfectly tolerated by the eye, and are soft and small so they can be painlessly injected into the eye in just a few seconds through a very small incision in the cornea. Once injected, the ICL lens unfolds and settles into position in front of the crystalline lens and behind the iris. Once inside the eye the lens is invisible and cannot be felt at all.
The ICL lens is intended to remain in the eye indefinitely. The advantage is that it can be removed when needed as it does not damage the structures of the eye.
That’s all! The entrance has no suture, seals naturally and heals in a very short time.
ICL implantation is considered outpatient surgery and takes approximately 15 minutes per eye. A few hours after surgery, they can leave the clinic and return to their activities.
Candidates for the ICL
ICL lenses can correct most refractive problems where Lasik is not indicated.
Myopia and/or high astigmatism.
Thin cornea.
Dry eye.
Alterations of corneal morphology.
Technique
Through a small 3 millimeter incision made on the edge of the cornea, we introduce a small applicator through which the lens is injected. Once inside the eye, the lens is opened and placed either in the anterior chamber or in the posterior chamber of the eye. Once the implant has been performed, the incision is sealed without the need for stitches.
For lens placement, we use local anesthesia. The procedure is painless and the patient returns home after the operation, but must keep the eye covered until the following morning.
In cases where myopia or hyperopia coincide with astigmatism, lens implantation can be complemented with the subsequent application of laser, obtaining surprisingly accurate results.
Candidates
Current excimer laser surgical techniques are limited by the thickness of the cornea (which, under normal conditions, is around 500 microns) and other factors such as corneal and pupillary parameters.
This system can usually remove up to approximately 10 diopters of myopia and 6 diopters of astigmatism or hyperopia.
With lasers, above these prescriptions, the desired quality of vision is often not achieved.
There are cases in which, either because of excess diopters, or because the cornea is too thin, or for other less common causes, the laser limits are exceeded. In these cases, the placement of INTRAOCULAR LENSES is used as a solution of great precision and with which a high quality of vision is achieved.
Candidates for this technique are practically all cases of myopia and hyperopia (even with low diopters) in which the previous ophthalmologic examination rules out the existence of any ocular pathology, although at Clínica Ocular Dr Tirado we usually reserve its use for high graduations.
Iintraocular Implant
Intraocular lenses are made of acrylic materials which, being inert, are perfectly tolerated by the body and do not cause rejection phenomena.
There are different types of intraocular lenses, varying in design and placement in the eye. Thus, there are posterior chamber lenses, which are placed behind the pupil, and anterior chamber lenses, which are placed in front.
Depending on the characteristics of each eye and with the help of the tests previously performed (ultrasonic measurement of the eye parameters, endothelial cell count, etc.), the surgeon decides the most appropriate lens for each case.
