Lasik : eye surgery at Laser
LASIK (Laser-Assisted In Situ Keratomileusis) is a type of eye surgery that uses a laser to reshape the cornea in order to improve vision. The surgery is typically used to correct common vision problems, such as nearsightedness, farsightedness, and astigmatism.
During the LASIK procedure, the surgeon will create a thin flap on the cornea using a special cutting tool or a femtosecond laser. The flap is then lifted, and a computer-controlled excimer laser is used to reshape the cornea by removing tiny amounts of tissue. The flap is then replaced and allowed to heal naturally without the need for stitches.
LASIK surgery is generally considered safe and effective, and most people who undergo the procedure experience improved vision without the need for corrective eyewear. However, like any surgical procedure, there are potential risks and complications, such as dry eyes, glare or halos, overcorrection or undercorrection of vision, and infection.
It is important to have a thorough discussion with an ophthalmologist or a qualified eye surgeon before undergoing LASIK to ensure that you are a suitable candidate for the surgery and it is essential to thoroughly comprehend the possible advantages and risks.
What is Lasik?
LASIK, which stands for Laser-Assisted In Situ Keratomileusis, is a refractive surgery technique designed to correct common vision problems like nearsightedness, farsightedness, and astigmatism. It involves using a laser to reshape the cornea, the clear front part of the eye, in order to improve the way it focuses light onto the retina at the back of the eye.
During LASIK surgery, a thin flap is created on the cornea, and a laser is used to remove some of the corneal tissue underneath the flap, reshaping the cornea so that it can better focus light onto the retina. The flap is then put back into place, and the cornea is allowed to heal naturally. The duration of the entire LASIK procedure typically lasts around 15 minutes for each eye.
LASIK is a highly effective and popular surgery for correcting vision problems, with most patients experiencing improved vision within a few days after the surgery. However, it is not suitable for everyone, and there are some risks and potential complications associated with the procedure. It is important to have a thorough discussion with an eye doctor to determine if LASIK is right for you and to fully understand the potential risks and benefits.
Lasik : what you need to know before you start
If you are considering LASIK surgery to correct your vision, there are several things you should know before you start.
Here are some key things to keep in mind :
- Consultation : The first step is to schedule a consultation with a qualified eye doctor who specializes in LASIK surgery. During the consultation, the doctor will evaluate your eye health and determine if you are a good candidate for the surgery ;
- Eligibility : LASIK is not suitable for everyone, and there are certain eligibility criteria that must be met. For example, you must be over 18 years of age, have a stable prescription for at least a year, and have healthy eyes without any conditions that could affect healing ;
- Risks and benefits : As with any surgical procedure, LASIK carries some risks and potential complications, such as dry eyes, glare, halos, and overcorrection or undercorrection of vision. It is important to fully understand these risks and weigh them against the potential benefits of the surgery ;
- Recovery time : You should expect to take some time off work or other activities after LASIK surgery to allow your eyes to heal. During the recovery period, your doctor will give you personalized instructions on how to properly care for your eyes ;
- Cost : LASIK surgery can be expensive, and it may not be covered by your insurance. Be sure to fully understand the costs involved before you commit to the surgery ;
- Follow-up care : After LASIK surgery, you will need to attend follow-up appointments with your eye doctor to ensure that your eyes are healing properly and your vision is improving as expected ;
By considering these factors and discussing any questions or concerns with your eye doctor, you can make an informed decision about whether LASIK surgery is right for you.
How is the Lasik operation performed?
LASIK surgery is typically performed on an outpatient basis and takes about 15 minutes per eye. The procedure typically involves several general steps, which may include the following:
- Numbing the eye : Before the surgery, your eye will be numbed using special eye drops to minimize discomfort ;
- Creating the corneal flap : The surgeon will use a specialized instrument called a microkeratome or a femtosecond laser to create a thin flap on the surface of the cornea. Next, the surgeon carefully lift the flap, revealing the underlying corneal tissue ;
- Reshaping the cornea : A specialized excimer laser is used to reshape the cornea by removing tiny amounts of tissue. The laser is controlled by a computer and is programmed to precisely reshape the cornea according to your individual prescription ;
- Replacing the corneal flap : Once the cornea has been reshaped, the surgeon will carefully reposition the corneal flap back onto the eye’s surface. The flap will then adhere naturally without the need for stitches ;
- Post-operative care : Following the procedure, your eye doctor will provide you with specific instructions on how to care for your eyes during the recovery period. This may include using eye drops to prevent infection and reduce inflammation, avoiding rubbing your eyes, and avoiding certain activities that could put pressure on your eyes, such as swimming or contact sports ;
Most people experience improved vision within a few days after LASIK surgery, although it may take several weeks for your vision to fully stabilize. It is important to attend all follow-up appointments with your eye doctor to ensure that your eyes are healing properly and your vision is improving as expected.
The after-effects of Lasik surgery
After LASIK surgery, it is normal to experience some temporary side effects as your eyes heal. Here are some common after-effects of LASIK surgery :
- Dry eyes : LASIK can temporarily reduce tear production, leading to dry, irritated eyes. Your doctor may recommend the use of artificial tears to help relieve symptoms ;
- Blurred vision : Blurred vision is common in the days and weeks following LASIK surgery, as your eyes adjust to their new shape ;
- Sensitivity to light : Your eyes may be more sensitive to light than usual after LASIK surgery, so it’s important to wear sunglasses or other protective eyewear as needed ;
- Glare and halos : You may experience glare or halos around lights, especially at night. Typically, this is a temporary condition that is expected to improve gradually;
- Eye discomfort : Some people experience mild eye discomfort or a feeling of pressure in the eye after LASIK surgery. Your doctor may recommend over-the-counter pain relief medication if needed ;
It’s important to follow your doctor’s instructions for post-operative care, including using eye drops as directed, avoiding rubbing your eyes, and attending all follow-up appointments. Most people experience significant improvement in their vision within a few days to weeks after LASIK surgery, and the after-effects generally subside within a few weeks. However, it’s important to contact your doctor if you experience any persistent or worsening symptoms.
