Can Xi'an Ophthalmic Astigmatism Surgery Be Cured Completely?
Ophthalmic astigmatism is a kind of common ocular refractive abnormality, and the patients appear blurred when they look at objects at close range. Many people often choose surgical treatment after suffering from astigmatism in order to get a complete recovery. So, can Xi'an ophthalmic astigmatism surgery be completely cured? This article will elaborate on the operation principle, operation effect, postoperative nursing and risk.
Operation principle
The astigmatism surgery in Xi'an mainly adopts laser correction. The cornea is reshaped by laser to change the focus of light on the retina, so as to correct astigmatism. Laser surgery can eliminate or reduce astigmatism by changing the curvature of the cornea, so that patients can obtain clear vision when looking at objects at close range.
During the operation, the doctor will use professional laser equipment to accurately etch the cornea according to the patient's corneal topography and diopter data to change it to the ideal curvature. The whole operation process usually takes only a few minutes. After the operation, the patient can immediately recover to a better vision, but it may take weeks or even months for the vision to gradually stabilize.
Surgical effect
The effect of astigmatism surgery in Xi'an ophthalmology varies from individual to individual, but generally speaking, most patients can obtain significant vision improvement and astigmatism correction effect after surgery. After vision recovery, patients can get rid of the trouble of relying on glasses or contact lenses, and improve the quality of life.
The durability of surgical effect is an important issue for patients. Research shows that the effect of laser correction is generally stable, and the vision of most patients after surgery can be maintained at a certain level, lasting for several years or even longer. However, a small number of patients may have vision regression and may need further corrective surgery or glasses.
Postoperative care
The postoperative nursing of Xi'an ophthalmic astigmatism surgery is very important. Correct nursing can help patients recover better and avoid complications. In a period of time after surgery, patients need to follow the guidance of doctors, and pay attention to the following points:
1. Avoid severe eye irritation, such as strenuous exercise, swimming, etc., to avoid causing inflammation or infection.
2. Use eye drops and ointment recommended by doctors to accelerate the healing of eye tissues.
3. Avoid rubbing eyes to avoid affecting the surgical effect.
4. Visit again regularly to monitor the recovery of vision and deal with any discomfort in time.
Risks and precautions
Xi'an ophthalmic astigmatism surgery is a safe and effective correction method, but there are still some risks and precautions:
1. The surgery may cause complications, such as dry eye, keratitis, etc., but the probability of these complications is low and can be effectively controlled through timely treatment.
2. Vision fluctuation or regression may occur after surgery, which may require further corrective surgery.
3. Individual differences are large, and the surgical effect and recovery speed will vary from person to person.
It should be noted that astigmatism surgery cannot completely eliminate the possibility of ocular refractive abnormalities. The diopter of the eyes may change with age, and further corrective surgery or glasses may be required.
Summary
To sum up, Xi'an ophthalmic astigmatism surgery can correct astigmatism to a large extent, so that patients can obtain good vision recovery and astigmatism correction effect. The operation principle is simple and clear, and the operation effect is generally lasting and stable, but postoperative nursing and regular follow-up are still very important. At the same time, there are still some risks and precautions in the operation. Individual differences are large, and the operation effect and recovery speed vary from person to person. Astigmatism surgery can not permanently cure ocular refractive abnormalities, but it can greatly improve the quality of life of patients and reduce dependence on glasses and contact lenses.
