While you have to undergo Laser eye surgery for the first time, it is obvious to feel nervous about it. But the expectation before, during, and post-operation is entirely dependent on the individual patient. However, there are some basics that you need to know regarding the surgery. Read on this blog to know the preparation and basic expectation at the time of laser eye surgery.
Before Laser eye surgery
You cannot decide that you will undergo Laser eye surgery in London as a baseline or initial ophthalmologist evaluation is needed for that. Only an eye specialist can check whether you really need any surgery or not! Even it is assessed whether you are an ideal candidate for this type of surgery or not.
Here are some basic expectations about laser eye surgery. If you have to wear contact lenses then say “no” to them. You will be advised to switch to wear full-time glasses. This is so; because contact lenses forcefully change the cornea’s shape.
Once you stop wearing them the cornea will be reverted back to its own shape again. Otherwise, it can affect the outcome of the laser eye surgery. Not only inaccurate measurements it leads to improper surgical plan as well that may end up with poor vision in the end.
Measurements include the amount of corneal tissue that needs to be removed on your eye assessment before the operation. So, it is highly advisable to avoid putting on hard or RGP lenses. Otherwise, in case you wear;
- Soft contact lenses, it must be stopped 2-week before the eye appointment
- RGP (Rigid Gas Permeable) or toric soft lenses, it must be stopped before 3-week of the initial eye evaluation.
- Hard lenses, must be stopped about a month ago before the primary eye check-up.
The ophthalmologist must be informed about:
- Any medication you are allergic to
- The medication you are currently taking including OTC (over-the-counter) medications
- The previous and current eye and overall health condition (if any)
After performing an extensive eye exam the eye specialist will discuss regarding:
- Your role before, during and after the operation
- Your expectation before, during and post-surgery
- The alternative of this surgery along with its benefits and potential risks
- If you are eligible for laser eye treatment or not
At the time of consultation, you should raise all your queries. Devote much time during discussion as it will benefit you. You can come to know about several pivotal pieces of information about the laser eye surgery.
Moreover, the eye surgeon will answer all your queries before you are inclined to this surgery and signed the consent form to undergo the procedure. But no one is supposed to pressurize you about the surgery along with friends, family or the doctor too. Furthermore, the merits and demerits must be considered as well before you make the final decision.
Just the night before your surgery stop using:
- Perfumes and apparels
These products will leave residues and debris in the eyelashes that can complicate the procedure and heighten the infection risk post-operation. Scrubbing of the eyelashes is recommended for a few minutes just before the surgery to ensure that no debris and residues are left along.
You should arrange for transportation before the surgery as well. So, you can commute to the Laser eye surgery clinic and get the first follow-up visit easily. On your operation day, some medicines and sedation will be administered to make you feel relaxed.
As it makes the vision blurry and impairs the driving ability, you should take along anyone at the clinic. The person will incorporate you while returning home post-surgery.
During Laser eye surgery
Laser surgery rarely lasts for 30 minutes. You will be laid on the reclined chair on your back in the operation theatre equipped with a laser system. This room will be also featured with a big machine, a microscope, and a monitor to observe. At first, numbing drops will be administered to your eye and its surrounding areas will be cleared.
Then, the equipment commonly known as lid speculum is used for holding the eyelids open. A mechanical microkeratome (blade-like device) is used for cutting the flap in your cornea. With the use of a mechanical microkeratome, a ring is typically placed in the eye with great pressure for suctioning the cornea. The vision gets dimmed while there will be the ring.
Some slight discomfort and pressure are a normal part of the process. The ring will be attached to this suction ring. The blades of microkeratome are meant to be used only once for cutting the flap of the cornea. Sometimes, laser keratome (a laser device) is also used for cutting the cornea’s flap. Then the clear plastic plate will be used for flattening the cornea.
The vision will get dimmed similarly too by increasing the discomfort and pressure. Laser enables us to penetrate inside the tissue of the cornea resulting in producing thousands of tiny bubbles of water and gas. These will expand and get connected to each other naturally below the cornea making the flap. At last, the plate gets removed from the eye.
Vision will get corrected but there will be high fluctuation of the blurry vision throughout the process. At last, the eye surgeon will lift up the flap to fold it by the hinge so that the exposed tissue gets dried up completely. After positioning of the laser you have to ask to stare at it.
It is not the laser surgery but done for removing the tissue from your cornea. It mainly assists in keeping the eye fixed to a specific position so that the surgery can be performed properly. Moreover, you have to look at this for at least a minute. If you fail then you will not be eligible for the surgery.
Once the eye fixes at the perfect position, laser surgery will be commenced by the surgeon. During the procedure, you will get familiarised with several new smells and sounds. Ticking sounds of the laser is the most common among them. When the corneal tissue will be removed you can get an odor of burning hair.
Laser energy amount will be controlled by the computer before it is administered. Prior to the surgery, eye conditions will be evaluated for determining the tissue amount needs to be vaporized by the help of the computer system. Once vaporization of the corneal tissue is done, the flap will be put back to its own position.
On completion, a specific shield must be placed on the eye to protect it from further injury. It is done because no stitches are done in today’s eye surgeries for holding the flap back to its own place. This abstains from rubbing the eye and exerting much pressure on it while sleeping. Even it prevents the eye from being poked, hit or bumped until it gets healed completely.
After Laser eye surgery
Right after any eye surgery, burning or mild itching sensation is common for a couple of hours! Sometimes you can also feel mild pain or slight discomfort with your eyes. At that time, your eye surgeon will administer a mild pain reliever to you. Not only teary or watery but also the vision will be blurry or hazy as well.
Of course, there will be a high tendency for rubbing the eye but never attempt it. Additionally, the sensitivity of the eye will be increased to haloes, starbursts, glare, and light. Even the white viscose of the eye turns red like bloodshot. These conditions will eventually fade away although these are common.
In the meantime, you should take a short break from your daily routine including professional life. In case there is severe pain or much worse of your vision, you should schedule an immediate ophthalmologist appointment without any further delay. On completion of the surgery, the doctor will check your eye condition at regular intervals in the first 48 hours.
Later the follow-up check-up should be continued for 6-month. During the very first postoperative appointment, the eye shield will be removed and the vision will be examined by the doctor along with recovery. A few kinds of eye drops will be prescribed to you as prevention against further inflammation or infection. For lubricating the eye, sometimes you may be suggested to wear artificial lens.
But don’t wear it in the operated eye if you are still experiencing blurred vision. To commence any light exercise, you have to wait for 1-3 days however; the activity amount is entirely depended on your recovery rate and your surgeon’s instructions.
For protecting your eyes from infection, it is generally advised to wait for a couple of weeks post-surgery till doctor’s suggestion to use makeup, creams and lotions. Scrubbing of the eyelashes for a certain time period should be also avoided after surgery.
Using of sauna, hot tubs, whirlpools and swimming pool must be stopped for about 2 months. You must not attempt any strenuous sport activities like karate, football and boxing at least for a month. You should be responsible enough for protecting your eye from infection, bump or any hit.
- Fluctuation of vision is common for the first initial months.
- Stabilisation of vision may consume 3-6 months post operation.
- Persistence of driving difficulty at night, haloes, glare and other mild vision symptoms will be there during this period. If there is any need of further enhancement or correction, you should wait for at least 2 doctor visits or 3 months to re-operate.
- Though distance vision may get improved within much less days yet certain visual symptoms will need more time to get improved.
- There is no eye clinic that offers proper evidence regarding the effectiveness and safety of further enhancement surgery.
