Understanding Side Effects After LASEK in Christchurch
LASEK, or Laser-Assisted Sub-Epithelial Keratectomy, is a refractive eye surgery that reshapes the cornea to improve vision. While it is a popular choice for those seeking to reduce dependency on glasses or contact lenses, it is important to understand the potential side effects associated with the procedure. This article will delve into several aspects of post-LASEK side effects, providing a comprehensive overview for individuals considering this surgery in Christchurch.
1. Immediate Post-Operative Symptoms
Immediately following LASEK surgery, patients may experience a range of symptoms. These can include mild to moderate pain or discomfort, a sensation of grittiness or sandiness in the eyes, and excessive tearing. Vision may also be blurry or hazy for a few days. These symptoms are typically managed with prescribed pain relief and eye drops, and they generally subside within a week.
2. Corneal Haze and Dry Eyes
Corneal haze is a common side effect of LASEK, characterized by a slight cloudiness of the cornea. This can affect vision, particularly in low light conditions. While it usually resolves on its own within a few months, in some cases, it may persist longer. Dry eyes are another frequent issue post-LASEK, caused by the surgery's impact on the corneal nerves. This condition can be managed with artificial tears and other lubricating eye drops, and it typically improves as the nerves heal.
3. Infection and Delayed Healing
Although rare, there is a risk of infection following LASEK surgery. This can lead to complications such as delayed healing or even vision loss. Strict adherence to post-operative care instructions, including the use of antibiotic and anti-inflammatory eye drops, can significantly reduce this risk. Patients should also be vigilant about monitoring any signs of infection, such as increased redness, pain, or discharge, and seek immediate medical attention if these occur.
4. Over-Correction or Under-Correction
In some cases, LASEK may result in over-correction or under-correction of vision. Over-correction occurs when the surgery improves vision beyond what was intended, leading to hyperopia (farsightedness). Under-correction, on the other hand, means that the desired vision improvement was not fully achieved. Both conditions may require additional treatment, such as glasses, contact lenses, or a follow-up surgery, to achieve the desired outcome.
5. Light Sensitivity and Glare
Post-LASEK, patients may experience increased sensitivity to light and glare, particularly in bright environments or while driving at night. This is often temporary and improves as the eyes heal. Wearing sunglasses and using anti-glare coatings on eyeglasses can help mitigate these symptoms during the recovery period.
6. Long-Term Outcomes
Most patients experience significant vision improvement within a few months after LASEK surgery. However, it is important to note that long-term outcomes can vary. Some individuals may continue to experience mild side effects or require periodic adjustments to maintain optimal vision. Regular follow-up appointments with an eye care professional are essential to monitor progress and address any ongoing issues.
Frequently Asked Questions (FAQ)
Q: How long does the recovery period last after LASEK?
A: The recovery period typically lasts about one to two weeks, during which patients should avoid strenuous activities and follow all post-operative care instructions.
Q: Can LASEK be repeated if necessary?
A: Yes, LASEK can be repeated if necessary, although this is generally considered only after careful evaluation and consideration of the risks and benefits.
Q: Are there any lifestyle restrictions after LASEK?
A: Patients should avoid swimming, using hot tubs, and exposing their eyes to dusty or smoky environments for at least a month after surgery to prevent infection.
Q: What is the success rate of LASEK?
A: LASEK has a high success rate, with most patients achieving significant vision improvement. However, individual results can vary based on factors such as pre-operative vision and overall eye health.
Understanding the potential side effects of LASEK surgery is crucial for making an informed decision about undergoing this procedure. By consulting with a qualified eye care professional and following post-operative care guidelines, patients in Christchurch can maximize their chances of a successful outcome and enjoy improved vision.
