LASIK, which stands for Laser-Assisted In Situ Keratomileusis, is a popular surgical procedure used to correct vision problems such as nearsightedness, farsightedness, and astigmatism. Astigmatism is a refractive error that occurs when the cornea or lens of the eye is irregularly shaped, causing blurred or distorted vision. Many people with astigmatism opt for LASIK surgery to improve their visual acuity and reduce their dependence on corrective lenses.
When it comes to the longevity of LASIK for astigmatism, it is important to understand that the procedure aims to permanently reshape the cornea to correct the refractive error. While LASIK is considered a permanent solution, it is essential to note that the eyes can still change over time due to age-related changes or other factors.
The long-term effectiveness of LASIK for astigmatism depends on various factors, including the severity of the astigmatism, the stability of the patient’s prescription, and individual healing responses. In general, LASIK has been shown to provide long-lasting results for astigmatism correction. Studies have demonstrated that the majority of patients maintain their improved vision for many years after undergoing LASIK surgery for astigmatism.
However, it is not uncommon for some patients to experience a gradual regression of their vision over time. This can occur if the cornea undergoes further changes or if new refractive errors develop. In such cases, a follow-up procedure called an enhancement or touch-up may be necessary to fine-tune the initial LASIK correction.
This additional procedure can help restore optimal vision and ensure long-lasting results for astigmatism correction.
LASIK surgery is an effective and long-lasting option for correcting astigmatism. While results can vary from person to person, the majority of patients enjoy improved vision for many years after the procedure. However, it is important to have realistic expectations and understand that ongoing changes in the eyes can occur over time. Regular eye exams and discussions with an experienced ophthalmologist are essential to monitor any changes and address them promptly to maintain optimal visual acuity.
Does LASIK Fully Cure Astigmatism?
LASIK is a highly effective procedure for correcting astigmatism, but it is important to note that it does not necessarily fully cure the condition. Astigmatism is caused by irregularities in the shape of the cornea or lens, and LASIK aims to reshape the cornea to improve vision.
While LASIK can significantly reduce astigmatism and greatly improve visual acuity, there is a possibility of residual astigmatism remaining after the procedure. The extent of residual astigmatism varies from person to person and depends on various factors such as the severity of the initial astigmatism, the skill of the surgeon, and the healing process of the individual patient.
How Is LASIK Performed for Astigmatism?
LASIK for astigmatism involves several steps to correct the irregular shape of the cornea. Here is a brief overview of the LASIK procedure for astigmatism:
The surgeon administers eye drops to numb the eye and uses a specialised tool to hold the eyelids open.
Creation of the Flap :
The surgeon creates a thin, hinged flap on the cornea using a microkeratome or femtosecond laser. This flap is then lifted to expose the underlying cornea.
Reshaping the Cornea :
Using an excimer laser, the surgeon precisely removes tissue from the cornea to reshape it according to the desired correction for astigmatism. The laser ablates the cornea in a controlled manner, guided by a computer program tailored to the patient’s specific needs.
Repositioning the Flap :
After the cornea has been reshaped, the surgeon carefully repositions the corneal flap back into place, where it adheres naturally without the need for stitches.
Recovery and Follow-up :
The patient is provided with post-operative instructions and scheduled for follow-up visits to monitor the healing process and ensure the best possible outcome.
Is LASIK Painful for Astigmatism?
One of the most common concerns of individuals considering LASIK for astigmatism is whether the procedure is painful. Fortunately, LASIK is typically not painful. Before the procedure begins, numbing eye drops are administered to ensure the patient’s comfort. The surgeon may also offer a mild sedative to help the patient relax.
During the procedure, most patients experience a sensation of pressure or mild discomfort, but not pain.
The entire LASIK procedure for astigmatism usually takes only about 15 minutes per eye, and any discomfort or mild irritation typically subsides within a few hours or days after the surgery. Following the surgeon’s post-operative care instructions and attending all follow-up visits is crucial for a smooth recovery and to minimise any potential discomfort.
What Is the Cost to Perform LASIK for Astigmatism?
The cost of LASIK for astigmatism can vary depending on several factors such as the geographical location, the reputation and experience of the surgeon, the technology used, and any additional services or warranties offered by the clinic.
On average, the cost of LASIK for astigmatism ranges between ₹60,000 and ₹80,0000 per eye. It is important to note that this cost typically includes the pre-operative consultation, the LASIK procedure itself, and the post-operative care for a specified period.
Some clinics may also offer financing options to make the procedure more affordable for patients. It is advisable to consult with multiple LASIK providers and inquire about their pricing structure, payment options, and any potential hidden costs.
LASIK is a highly effective surgical procedure for correcting astigmatism, but it does not guarantee a complete cure for the condition. Residual astigmatism may still be present after LASIK, although it is often significantly reduced.
The procedure itself is generally not painful, with most patients experiencing only mild discomfort or pressure. The cost of LASIK for astigmatism varies depending on various factors, and it is important to consider the quality of the surgeon and the clinic rather than solely focusing on the price. Consulting with multiple providers and thoroughly discussing the procedure, potential outcomes, and associated costs will help individuals make informed decisions about LASIK for astigmatism.
