What are the Different Kinds of Refractive Eye Surgery
Hyperopia or farsightedness, myopia or nearsightedness, and astigmatism are three of the most common eye problems that over millions of people around the world suffer from. What these three eye complications have in common is that they are refractive errors which are the result when light is not properly focused right onto the retina of the person’s eyes which is what happens when their corneas are irregularly shaped. People who suffer from refractive errors look towards corrective devices like contacts and glasses which help adjust light coming in so that the focus hits the retina properly.
However, places like the Houston Eye Center offer other solutions which may be a viable option especially for those who dislike glasses or contacts which can get in the way at times and even be lost rendering one basically blind. These other solutions come in the form of refractive surgery which is performed by eye surgeons who work with the right tools and equipment to treat the eyes of their patients. Today we are going to take a look into the different kinds of refractive surgery.
1.) Intracorneal ring segments – Intracorneal ring segments or intacts for short are thin plastic implants which are implanted onto the peripheral cornea of a patient which causes the cornea to flatten out. Intacts are only used in light cases of myopia and can treat up to negative three diopters of nearsightedness. Note that recovery isn’t as fast with intacts.
2.) Lasik eye surgery – This type of refractive surgery involves using an excimer laser to ablate or reshape the patient’s cornea. Lasik Surgery results in a more “long term” result and patients who have undergone lasik eye surgery may no longer have a need for corrective devices in the future. However, there are also risks like the development of side effects associated with lasik surgery.
3.) Phakic intraocular lenses – In cases where other forms of refractive surgery are no longer ideal options especially in patients who suffer from extreme nearsightedness, Phakic intraocular lenses are implanted onto the eyes of the patient and it can help treat up to negative twenty diopters of myopia or nearsightedness.
4.) Conductive keratoplasty – Conductive keratoplasty or CK treatment for short offers a temporary solution to patients who have hyperopia and presbyopia. In this surgical procedure radio waves are directed onto the peripheral area of the cornea which results in it shrinking and becoming step in the center. This treatment is quite safe but it doesn’t last long and regression can occur within a few years.
5.) Advanced surface ablation – This form of refractive surgery is actually a more advanced form of lasik eye surgery. Where lasik eye surgery requires the surgeon to cut out a corneal flap in order to access the corneal tissue underneath to proceed with the ablation process, advanced surface ablation doesn’t. During the surgical process, the epithelium (the cornea’s top most layer) is also reshaped.
So these are the different types of refractive surgery. If you know someone who is considering undergoing one, look to Houston Eye Center which can offer you great quality service with their facilities and skilled eye surgeons.
