Phakic intraocular lenses (phakic IOL) or commonly known as implantable contact lenses are lenses that are implanted into the eye so that they could work with the crystalline lens to correct myopia or farsightedness – a state where the person involved could not see far distance object clearly. Implantable contact lenses can correct a wider range of myopia compares to a laser refractive procedure. And this is the reason why it is more preferred nowadays compares to the latter.
Unlike an intraocular lens which will replace the eye’s natural lens completely, an implantable contact lens is an additional lens that placed into the eye to work together with the eye’s natural lens.
Intraocular lens is basically used when the natural lens could no longer work and needed a replacement such as in the case of eye cataract. On the other hand, implantable contact lenses are used for the sole purpose of rectifying the vision problems, in which the natural eye lens is still in a good condition but rather requires correction in the angle of vision. Well, it works just how a normal contact lens does its job.
This is a very simple surgery and the patient can rest assured that it is very safe (There is still risk involved but it varies for different individual case, please consult your doctor for more advices). Moreover, unlike any other lens replacement surgery, these types of lenses can be removed without doing any damage to the natural lens and so if the patient does not feel comfortable with it, he or she always can have it removed without any problem. This surgery rarely cause any discomfort issue as it is quite the same as a normal contact lens. And so if the patient does not have issue with the contact lens, he or she should be alright with implantable contact lenses.
Quite normally, the doctor will only implant one lens at a time before proceeding to the next one. The reason for this is to provide the patient with a period of settling time so that he can make use of it before proceed with the other eye. However, the doctor will still perform surgery on both eyes under special request from the patient.
The patient will able to see clearly once the procedures are done. And most importantly, he or she does not need to rely on the contact lens for temporary vision correction.
