Wuhan Laser Orthopaedic Eye Hospital: What are the sequelae of laser ophthalmic surgery?
Laser correction ophthalmic surgery is a common vision correction method, which can help patients get rid of the problem of relying on glasses or contact lenses. However, any operation may have some risks and sequelae. The following will elaborate on the sequelae of laser correction ophthalmic surgery from the aspects of vision recovery, dry eye, postoperative photosensitivity, and surgical failure.
1. Vision recovery
Most patients will have short-term blurred vision after surgery, and it will take some time for vision to gradually recover. This is a normal physiological reaction, which usually disappears within a few days to weeks after the operation. However, a few patients may have vision fluctuations, that is, postoperative vision is sometimes good and jet lag. This situation needs further evaluation and adjustment by doctors.
In addition, the patient's myopic degree may not be completely corrected to the ideal state, and there may be some residual ametropia. This situation can be improved through subsequent observation and adjustment.
It is worth mentioning that the patient's age will also affect the surgical effect. The growth and development of the eyeball will cause changes in the degree, but laser correction surgery cannot change the growth of the eyeball. Therefore, the surgical effect of adolescent patients may be relatively unstable.
2. Dry eye
Dry eye is one of the most common sequelae of laser ophthalmic surgery. After surgery, some patients may feel dry, painful, hot eyes, and even photophobia and eye fatigue. This is because a part of the cornea was cut off during the operation, which stimulated or damaged the nerve endings of the corneal tissue. Generally, this discomfort will relieve itself within a few months. Patients can relieve symptoms through eye drops, moisturizing ointment and other methods.
3. Postoperative photosensitivity
Laser correction ophthalmic surgery will change the curvature of the cornea and increase the focusing ability of light in the eyeball. Therefore, patients may be more sensitive to light after surgery, and even suffer from discomfort symptoms such as halo and night vision loss. This sensitivity will generally be gradually reduced within weeks to months after surgery, but a few patients may last longer.
4. Operation failure
Although the laser orthopaedic ophthalmic surgery technology has been very mature, there are still a few patients who may not achieve the desired effect or have surgery failure. The failure of operation may include the failure of vision to reach the ideal state and serious complications after operation. If the operation fails, the patient may need to be operated again or repaired by other methods.
Summary:
Laser correction ophthalmic surgery is a common method of vision correction, but there are also some sequelae. Visual acuity recovery requires a certain period of time, and may fluctuate within a few days to weeks after surgery. Dry eye is one of the most common sequelae. The surgery will lead to dry eyes, pain and other uncomfortable symptoms, but it will generally relieve itself in a few months. Postoperative photosensitivity is another common sequela. Patients may be more sensitive to light and need some time to adapt. Although the probability of surgical failure is low, there are still a few patients who may not achieve the desired results. Therefore, patients should fully understand the risks and sequelae of the surgery, and fully communicate and evaluate with doctors before carrying out laser corrective eye surgery.
