INTRA-OCULAR PHAKIC IMPLANTS
THE TREATMENT OF MYOPIA, ASTIGMATISM, AND HYPEROPIA WITH INTRA-OCULAR PHAKIC LENS IMPLANTS
If your pre-operative assessment is satisfactory and your eyes have no contraindications for surgery, then laser surgery may not be the best option for you. Your surgeon will choose the best solution for you in order to correctly match your expectations with the different treatment possibilities.
HOW THEY WORK
Surgery-implanted lenses, also known as intraocular lenses are a solution for those who seek permanent correction of vision disorders such as myopia, hyperopia, and astigmatism. These implants resemble contact lenses and are placed behind the iris through a small, self-sealing incision in the ‘blade’ (the line between the white of the eye and the cornea).
Unlike traditional contact lenses, you will not feel an intraocular lens in your eye. In addition, phakic implants require no maintenance. Nor do they require the ablation of your corneal tissue. They function in the same way as glasses or contact lenses except that they become integral parts of your eye by being implanted behind the iris to compensate for the your vision defects.
Visual recovery is fast.
The first implants were inserted in 1993 in Europe, so we now have more than twenty years of usage and experience without serious complications.
The selected implants are made from Collamer, a combination of collagen and polymer ; a material that is 100% bio-compatible with your eyes. They are one of the latest technological advances in vision correction technology. This FDA-approved technology also corrects large refractions.
This lens has many advantages :
Excellent vision quality :Due to its unique anti-reflective properties and its high water resistance, the Collamer can diffuse light in the same way as a natural crystalline lens. This allows cleaner and clearer vision. There are no halos or glare, no poor night vision, nor effects associated with other types of implants.
Bio-compatibility :The collagen present in the collamer attracts fibronectin, a substance naturally present in your eye. The intraocular lens is small and flexible, allowing it to be folded and injected painlessly in just a few seconds through a small incision in the cornea. Once injected, it unfolds and is positioned effortlessly between the iris and the crystalline lens and is perfectly accepted by the body.
Invisibility :It is invisible. It functions as a conventional contact lens, with the difference that it is placed inside the eye and not on its surface. Other than the fact that it corrects your visual disorder, you cannot see it, or feel it, so you’ll forget it’s even there !
Reversibility :It is removable. This lens is designed to remain indefinitely in the eye. It can however be removed if necessary because it does not alter or damage in any way the structures of the eye or the cornea.
UV protection :Long-term exposure to UV radiation can damage your eyes and increase the risk of blurred vision, and also includes the development of cataracts and retinal problems. Intraocular lenses contain a UV blocker that prevent UVA and UVB rays from entering the eye. Your eye is thus protected under all circumstances.
Results :Studies on this lens show a satisfaction rate of higher than 99%. In some rare cases it may be necessary to carry out additional laser treatment on the cornea in order to optimize the result.
Your operation in three steps :
Before your operation
The entire procedure for intraocular lens implantation lasts about 30 minutes. The procedure is painless. The anesthesia may be deep local, localized potentiated (neurolept-analgesia) or general. On the day of your surgery you will be prescribed an anxiolytic, if necessary. You will return to the operating room and will be given a sterile operating robe to wear. The procedure can then begin.
During your operation
During your operation you will be lying on an ophthalmological chair. After following strict antiseptic rules, the anesthesia of your choice is performed.
The procedure consists of two steps:
- The creation of one or two small openings at the base of the cornea, which will be used to position the lens.
- The insertion of the correction lens, chosen according to your visual impairment.
The procedure is not painful and is perfectly safe. We use the ZEISS OPMI LUMERA 700 Microscope.
After your operation
During the first hours it is advisable to rest with eyes closed. Transparent googles are recommended to wear while sleeping during the first week. Following your surgeon's instructions, you will start the antibiotic and anti-inflammatory treatment on the evening of the procedure as indicated on the prescription.
It is essential not to expose yourself to "at risk" atmospheres during the first week. Avoid all situations that may expose your eyes to micro-organisms (bacteria, viruses, fungi). It is essential to observe strict rules of hygiene, in particular to washing hands thoroughly before putting in your eye drops. You should also avoid rubbing your eyes, and of course avoid eye trauma.
Post-operative follow-up is provided by Dr. Donate. A follow-up visit is planned for the next day, then a week later, and then a month after the surgery.
