You can begin by searching on the internet for an eye surgeon who has an established track record and proficiency in your procedure of choice. Cross check your findings with friends or relatives who have undergone the procedure as well as blog posts by those who have had the procedure done. The surgeon’s years of experience and track record of the clinic he practices in are further important points to consider.
astigmatism and presbyopia (middle-aged onset far sightedness).
SUITABILITY FOR TRANSPRK PROCEDURE
past three years. Parental consent is needed for patients who are 21 years old and below.
There is no maximum age limit, but those over 60 years of age may have underlying eye medical problems, for example cataract, and should undergo a medical eye examination first.
you are a suitable candidate for the procedure. The LVC evaluation would consist of detailed tests & eye measurements followed by a medical eye examination & consultation with the eye surgeon himself.
Some factors that will determine your suitability include your cornea thickness, cornea curvature, keratectasia risk, total refractive power, and any existing eye conditions such as glaucoma, cataracts,etc.
CXL is a simple two-minute procedure that involves 2 steps:
1. Riboflavin (Vitamin B2)* eye drops are applied to the cornea and left to soak into the cornea for 1 minute.
2. The riboflavin-soaked
cornea is illuminated with
ultra-violet A (UVA) light
for 1 minute using advanced
technology of the Avedro KXL® System, and this treatment cross-links the collagen fibers within the cornea, thus strengthening the cornea.
Your eye doctor is the best person to advise if you will need CXL or not.
You can see reasonably well after the procedure, but it is still not advisable to drive.
THE TRANSPRK PROCEDURE
the actual laser treatment time is about 10 to 50 seconds per eye.
POSSIBLE RISKS AND COMPLICATIONS
The most feared complication common to all the various laser vision correction techniques is infection. But with modern safety standards, the real on the ground experience is significantly less.
The next feared complication for TransPRK is corneal haze. Fortunately, this is unlikely to occur if the patient adheres strictly to the prescribed eyedrops regime, and wear sunglasses when outdoors in the sun, especially within the first month after the TransPRK procedure.
Other complications such as glare, halos and star-bursts complaints are now much less common with today’s modern lasers and techniques.
For TransPRK procedure, we are most concerned with complications from infection and haze due to exposure to uv rays. If the patient adhere to the eyedrops regime that is prescribed, keep good eye hygiene and stay away from excessive sunlight especially during the first month, the risk of complications that can lead to blindness is very unlikely.
It is important to wear your sunglasses and a cap when you are outdoors for the first month to reduce uv exposure to the eyes.
Most patients see well enough to return to work on Day 6.
Full vision recovery will greatly depend on the power corrected. Patients with low myopia power can expect to see very well by end of first month, moderate myopia power by end of second and those with high power after three months. Generally, most patients are discharged after the third or fourth month.
However, especially for the first month of the recovery period, you should remember to avoid exposure to the sun’s ultraviolet rays. Hence, engage in outdoor sports only before 8 am and after 630 pm.
known as middle-aged Farsightedness or “Lao Hua“ in Chinese. The most
common strategy is called “Mono-Vision treatment“, but I would personally prefer
the term of “Blended Vision treatment“. With this strategy, the dominant eye (yes,
we all have a dominant eye same as we all have a dominant hand and dominant leg)
will be corrected to see clearly for the distance, and the other eye (your non-dominant eye) corrected to see better for near vision. If the difference in the refractive power between the two eyes are kept at 1.50 Dioptres and below, the phenomenon of “Blended Vision“ occurs where for distance vision, the dominant eye helps the non-dominant other eye to see well for far also, and for near, the non-dominant eye helps the dominant eye to see better for near. Thus, rest assured that it is thus not a case of having only one eye see for far and one eye see well for far also, and for near, the non-dominant eye helps the dominant eye to see better for near. Thus, rest assured that it is thus not a case of having only one eye see for far and one eye see for near as the term Mono-vision Treatment suggests.
Nonetheless, always adopt the good eye care habits listed below:
1. Minimise eye strain
Placing too much strain on the eyes can cause discomfort and fatigue.
One of the best ways to prevent eye strain when doing near vision work
is to follow the rule of 20-20-20. This simply means that every 20 minutes of near vision work, you should look at objects 20 feet away for 20 seconds!
2. Do not hold reading materials too close to the eyes Maintain a comfortable distance between your eyes and reading materials. For reading, the ideal distance is 2/3 of an arm’s length away.
3. Work in well-lit areas
It is important for one to work in bright spaces with sufficient and suitable lighting. Whilst dim lights will not directly damage your eyes, they can tire them out more quickly and cause eye strain symptoms and headaches.
4. Your sitting posture matters
Maintaining a proper sitting posture while working is important as well. Refrain from slouching! You should adopt a correct but comfortable sitting posture with the back straight and shoulders relaxed.
5. Maintain a healthy lifestyle
To keep your eyes healthy, it is important to consume nutritious food or supplements that has beneficial effects for the eyes. Spent sufficient time outdoors daily to engage in exercise or leisure activities daily.
However, for some patients, the doctor may not be able to achieve full correction due to limitations brought about by their high myopia, astigmatism or thin cornea. This category of patients may require low-power glasses to achieve perfect vision.
lenses cannot be worn as they tend to slip due to the altered cornea curvatures.
