Basic Information About Refractive Surgery

Refractive eye surgery is cosmetic eye surgery designed to alter the normal refractive condition of the eyes and reduce or even remove dependency on glasses or contacts. This can consist of many methods of cosmetic surgical repair of the iris, lens implantation, corneal flap or ligate scarring. As these procedures are considered to be non-invasive, there is no need to worry about any complications that may arise after the procedure.Chick here for more details about chirurgia refrattiva

Refractive surgery for the eyes involves three main stages: the preoperative stage, the preoperative diagnostic stage and the postoperative stage. The preoperative stage is very important because it is the first stage that deals with the identification and diagnosis of the problems that may cause refractive errors. During this stage, the patient's eyes are examined by a qualified eye surgeon so that he can provide the necessary treatment for the patients. During the preoperative stage, there may be changes in the intraocular pressure, visual field defects, irregular corneal structure, abnormal growth of cells and ocular hypertension.

In the diagnostic stage, the eye doctor examines the corneal tissue, the optic nerve and the retina. These are all important factors that determine the correct refractive correction. In addition, if a patient is already suffering from vision loss, other tests are usually carried out. If these tests show clear evidence of vision loss, the physician may choose to carry out an ocular examination in order to establish the exact refractive error and to decide whether corrective surgery is required.

After the diagnostic and preoperative phases have been completed, the patient will need some time to recover and be fully recovered from the surgical procedure. During this period, the patient should strictly follow the postoperative instructions given by his ophthalmologist so that the postoperative complications are minimized and any complications that may occur during the recovery period are easily managed. The postoperative instructions should include the amount of fluid needed to be administered, the amount of medication taken and the time taken for the patient to return to work or to school. The patient will also need time for recuperation and rehabilitation to be able to resume normal activities.

Another important thing to note before and after refractive surgery is that the patient must be cautious not to wear any glasses for at least four weeks or more than six months prior to and during the procedure. This is because eyeglasses may cause damage to the delicate corneal tissues and the corneal flap when the eye drops some tears during the procedure. This may lead to damage to the nerves leading to vision and eventually to visual loss of vision. For the safety of both the patient and the eye surgeon, the patient must always wear the disposable contact lenses or glasses until the postoperative period has been completed.

There is no need to worry about complications related to corrective surgery. Although there will be some risks and complications involved, there are usually few such risks and complications associated with refractive surgery. Also, there are a lot of benefits that are accrued from corrective surgery such as the improved quality of life that a patient will experience once the procedure is completed, the improvement of vision clarity, reduction or elimination of eye discomfort and many more.
