Is Lasik Surgery Safe? - Success Rate, Dangerous or Not

The success rate of LASIK surgery is 96%, indicating it is quite safe. According to the American Society for Cataract and Refractive Surgery, over 90% of patients experience 20/20 vision post-LASIK surgery, and nearly 100% patients obtain vision that is better than 20/40. 

Who is an ideal candidate for LASIK surgery?

Before prescribing LASIK surgery, the doctor will check if the patient is a suitable candidate and also how safe is LASIK laser eye surgery for them. This is because, many a time, patient related factors may impact the outcome of the surgery. Hence, to ensure that LASIK is safe for the patient and produces successful outcomes, it is important to determine who is the ideal candidate. The general criteria that a patient planning to undergo LASIK eye surgery must meet include the following,

1. To achieve safe LASIK surgery results, the candidate must not have certain health problems such as immune system diseases or diabetes.
2. The patient must not be taking any medicines that can compromise the immune system, such as immunosuppressants.
3. It is not known how safe LASIK surgery is during pregnancy. Additionally, hormonal changes during pregnancy can affect the stability of a woman's vision, which could affect the outcomes of LASIK surgery. Hence, it is advised for pregnant women to wait until after the pregnancy period is over before they undergo LASIK surgery. 
4. LASIK may not be safe for patients having eye problems as it may affect the healing process after the surgery. Hence, the patient must be free from eye problems like strabismus, glaucoma, keratoconus, dry eyes or amblyopia. 
5. LASIK surgery is safe only when done in patients above 18. However, in some cases, the doctors advise the patient to put the surgery on hold until they reach the age where their eyes have matured, which may be when they turn 21.
6. For the patient to be an ideal patient, they must have a stable vision for at least 12 months. Noticing changes in the prescription for corrective eyewear could mean that your corneas are changing. As a result, the outcomes of LASIK surgery may not last very long.

Just like any other surgical procedure, LASIK surgery is also affected by several factors. These factors are important to be considered while determining The safety of LASIK surgery. 

Is lasik surgery safe or not depends on several factors, such as, 

1. Patient-related factors: In order to maximise the safety of LASIK and get successful results, the patient needs to be an ideal candidate. 
2. Preoperative testing: Comprehensive eye exams, such as corneal topography, wavefront analysis, and measuring the thickness and shape of the cornea, can help identify any potential issues or contraindications for LASIK. 
   1. Additionally, the doctor may also check the patient’s past surgical history, personal history and family history before LASIK surgery. 
3. Surgeon experience and skill: The experience and skill of the LASIK surgeon performing the procedure are essential factors in ensuring the safety and success of the surgery. Choosing a trained and experienced surgeon with LASIK and up-to-date technology can improve the chances of a successful outcome. 
4. Technology and equipment: Advances in LASIK technology have improved the accuracy of the procedure and have made LASIK safer. 
5. Postoperative care: Proper postoperative care, including the use of prescribed medications, avoiding certain activities, and attending follow-up visits with the surgeon, can help prevent complications and ensure the best possible outcome.

Like any surgical procedure, LASIK (Laser-Assisted in Situ Keratomileusis) carries the risk of potential side effects. These side effects are mostly temporary and will resolve in a few weeks. Rarey, LASIK may cause loss of vision in the patient. The various risks of LASIK eye surgery include the following,

1. Dry eyes: This is a very common side effect that can last for several weeks or for around six months after the surgery. This is because LASIK may cause a decrease in the production of tears. Artificial tears and other treatments can help alleviate the symptoms.
2. Glare and halos: Some patients may experience glare, halos, or other visual disturbances, especially at night. These symptoms usually improve over time.
3. Undercorrection or overcorrection: Certain patients may feel LASIK is unsafe due to the risk of under-correction or overcorrection. Sometimes, the desired outcome of LASIK may not be achieved, resulting in an under-correction or overcorrection of the refractive error.
   1. Undercorrection occurs when a laser removes very little tissue from the eye. Overcorrection occurs when a laser removes too much tissue from the eye.
4. Flap complications: When the flap is folded back or removed from the front portion of the eye during surgery, a flap problem may arise.  This problem may cause complications such as infection, inflammation, or detachment.
5. Astigmatism: Uneven tissue removal during the surgery may cause astigmatism, which may require another surgery or glasses.

LASIK is a safe procedure with several benefits, making it an ideal choice for people with refractive errors. The various benefits of LASIK include the following, 

1. LASIK surgery is painless.
2. The procedure typically takes less than half an hour to complete.
3. The vision correction achieved by LASIK is usually permanent.
4. LASIK can eliminate the need for glasses or contact lenses.
5. If there are any changes to the patient's vision over time, the doctor can adjust as needed.

There are certain practices to be exercised after LASIK surgery to ensure the eyes' safety, prevent pain occurrence and ensure quick healing. In some cases, the patient may recover within 6 to 12 hours after the surgery, whereas, in certain cases, it may take about 3-5 days to recover. However, with proper care post surgery after surgery, the patient may recover quickly. The tips to follow after LASIK include the following, 

1. Wearing the protective shield while sleeping for about 7 days after the procedure
2. Getting adequate rest during the recovery period
3. Wearing glasses or sunglasses to protect the eyes from dust, smoke, and sunlight 
4. Scheduling follow-up appointments with the doctor for check-ups, typically for around six months after the procedure
5. Immediately inform the doctor and seek medical help if there is severe pain after LASIK surgery.

Certain things are to be avoided after LASIK surgery as they may be unsafe and dangerous. These things include the following, 

1. Avoid rubbing your eyes to try to improve your vision
2. Don't use any cosmetics or other products that could irritate your eyes without your doctor's approval
3. If you experience any vision problems after the laser surgery, it's essential to consult your doctor rather than resort to your old contact lenses.
