Refractive eye surgery is the general term used for surgeries designed to help people see more clearly. There are many variants of this kind of surgery, including laser eye surgery, cataract surgery and other procedures such as conductive keratoplasty. It is important to get a brief overview of these kinds of surgeries just in case you, or someone you know, should ever need to ever need this kind of treatment.
The most popular kind of refractive eye surgery is the laser surgery, or more specifically LASIK surgery. The reasons why it is more popular is that there is a relatively fast recovery time after LASIK, there are no visible marks left in the eye after surgery and that many patients have undergone this type of procedure. A popular refractive eye surgery like this also has its drawbacks, such as that the risks after LASIK surgery include flap complications, which could lead to eye infections, dry eyes and experiencing visual distortions such as glare, haloes, starbursts and double vision. This is a rare occurrence and such complications can usually be resolved by an enhancement surgery or simply by waiting for it to resolve itself ophtalmologues Courbevoie.
Cataract surgery is also a kind of refractive eye surgery, but only performed on those who have cataracts. Cataracts are normally caused by the lens of the eye losing its transparency, or becoming cloudy as we age. This is due to the lens continually adding lens fibres to itself, combined with metabolic changes. As such, the lens can no longer accommodate to focus the rays of light from an image onto the retina to form a sharp focus. Also, the loss of transparency of the lens causes light to be scattered around the eye and this also contributes to the blurriness of the image. What cataract surgery does is replace your lens with a clear artificial intraocular lens (IOL) so that you can see clearly again, even in old age.
There are other lessen known refractive eye surgery procedures as well. These types of surgeries are usually more applicable for those with long-sightedness, as laser eye surgery is more appropriate for those with short-sightedness and astigmatism. Nevertheless, these procedures are still in demand and it is still good to know one or two things about it. Conductive keratoplasty (CK) is one the lesser known procedures whereby a high frequency electric probe is used to emit radio waves to shrink the peripheral cornea. In doing so, this helps increase the power of the cornea and thus helps treat those with mild to moderate amounts of long-sightedness. There is also a more recent development called corneal inlays where a porous black ring is inserted under the corneal flap, as with LASIK surgery, or in a stromal pocket to help those with presbyopia.
As you can see, refractive eye surgery can be one of many surgeries. It all depends on your individual needs and preferences of the type of surgery that you want to have performed on you.
