Corneal surgery is also known as refractive surgery. and it includes the following types of procedures. It includes corneal transplant eye surgery, penetrating keratoplasty, keratoprosthesis, phototherapeutic keratectomy, pterygium excision, and corneal tattooing. All the aforementioned are forms of corneal modification surgery, and their purpose is to increase the function of the refractive state of the eye or lower the need for visual aids. Today, most forms of corneal surgery depend on photoablation by way of an excimer laser.
This kind of surgery is done for two reasons. The first has to do with taking away either scarring or clouding on the cornea that has the tendency to cloud over vision. The equally important, second reason is to modify or correct the cornea s curve in order to fix vision problems. Some of these problems may be, but are not limited to, farsightedness and nearsightedness.
As with any type of surgery, there are going to be people who make better candidates than others. In relation to corneal surgery, those who make good candidates for this procedure are generally people who are enduring corneal conditions. These conditions are permanent and stubborn: They cannot be corrected by just wearing contact lenses or glasses. Other people who make suitable candidates for corneal surgery include those people who are not pleased with their appearance with glasses and so want to correct their cornea for cosmetic reasons.
In corneal transplant surgery, the damaged cornea gets replaced by cornea tissue that s been donated; this transplant may be done in its entirety or only in part. In keratoprosthesis, a cornea that is no longer viable is replaced by a totally artificial cornea. Phototherapeutic keratectomy involves eye surgery where a laser treats eye disorders by removing certain tissue from the cornea. Corneal tattooing entails actually tattooing a patient s cornea, but this is done to improve the sight of the patient, although it may also be used for purely cosmetic purposes. Even patients using corneal tattooing for cosmetic reasons mainly do so to repair the image of their eye after it has been damaged in an accident or due to illness.
Corneal surgery is most commonly regarded as simply an outpatient type of operation. A site such as a same-day surgery center is usually where these types of procedures are carried out. After a successful surgery, the patient may still have to wear an eye patch to aid in recovery, and the patient is then wheeled into the surgery recovery room. A determination is made that the patient is ready to go home when the anesthesia wears off, and the patient is capable enough to drink fluids without feeling any nausea.
Once at home, the convalescing patient has to make sure he avoids the danger of infecting the eye. Antibiotic eyedrops are used for this purpose. For some patients, the use of artificial eyedrops referred to as artificial tears may be beneficial to make their eyes more comfortable. Most people who undergo the various types of corneal surgery enjoy good results and experience total vision correction. However, even so, the recovery time for this type of surgery can take several months, and some patients may still need to depend on visual aids. In this case, more surgery will be prescribed as a way of dealing with unsatisfactory results.
