LASIK is one of the most popular eye laser procedures used to correct refractive errors and eliminate the need for contact lenses and glasses. Near and distant vision problems can be corrected quickly and safely by using the Supracor technology. The patient’s suitability for LASIK laser eye surgery is determined by a pre-op eye examination. Highly advanced ophthalmological equipment is used for this eye examination. The data obtained is then fed into the LASIK system and the cornea is shaped according to the type of refractive error. Suitability for the LASIK procedure depends heavily on the thickness and curvature of the cornea, the amount and type of refractive error and other factors. If the patients have realistic expectations from the procedure and understand the small risks associated with it, they will be fully satisfied with it.
What are refractive errors?
Several types of refractive errors exist, including astigmatism, myopia and hyperopia. These errors are measured in dioptres – the bigger the error is, the thicker the corrective glasses lens.
Short-sightedness or Myopia
If the lens and cornea are too strong or too thick or if the eye itself is too long, the light will come into focus somewhat in front of the retina. Patients see distant objects as blurred but they can still see closer objects normally. Myopia usually develops during adolescence or childhood when the eye is still growing and ultimately stabilizes when the body’s development is over. The causes of myopia are unknown but environmental and inherited factors play a role in the development of this condition.
Long-sightedness or Hyperopia
If the lens and cornea are weak or not strong enough or if the eye is simply too short, the light comes into focus somewhat behind the retina – objects in the far distance will appear blurred. As the patient gets older glasses will become necessary to see closer objects as well.
Patients suffering from astigmatism have different curvatures on their cornea – with this condition focusing becomes distorted or uneven and objects cannot be seen properly without glasses or contact lenses either up close or in the distance. Astigmatism is a very common condition and people suffering from hyperopia or myopia tend to have astigmatism as well.
Presbyopia can be confused with hyperopia since their effects are basically the same, but the causes of these two conditions are different – presbyopia is part of the natural process of aging and the person has trouble in bringing up close objects into focus. Presbyopia usually starts at around 40-50 years of age.
Other refractive problems
Focusing of the eye may be affected by other problems such as corneal scars and keratoconus and while these conditions may not be treated with LASIK, other treatment options are available for patients.
To this date, more than 30 million people from the whole world had LASIK laser eye surgery. Clinical trials have proved that the majority of patients achieved and enjoyed a decrease in unwanted glare, improvement in vision quality, better vision than with contact lenses or glasses, less night driving difficulty and very high patient satisfaction rates, which go well into the 98%.
The advantages of LASIK are rapid vision recovery after the procedure, no scarring, near-perfect vision without contact lenses or glasses and very little discomfort during the surgery and recovery period.
Patients suffering from myopia or short-sightedness can benefit greatly from LASIK eye surgery. LASIK is also a solution for patients that suffer from hyperopia and astigmatism.

Since LASIK is not an option for every patient, TransPRK has been created as a no blade surface based, non-invasive procedure that is suitable for almost all candidates, especially those that cannot have LASIK laser eye surgery.
TransPRK may be a good option for patients with a very thin cornea or patients that had complications following a LASIK surgery. Scars from LASIK complications can also be treated with TransPRK – it can also be a better choice for patients with very high myopia.
The difference between LASIK and TransPRK is that the TransPRK doesn’t need a cornea flap – the laser procedure begins with the surface of the cornea and leaves you with a stronger cornea once the procedure is complete. In cases of high short sightedness errors, the cornea can be strengthened even more through the crosslinking technique which can stabilize the surgery result, the cornea shape and its structural integrity.
The TransPRK technology first removes the epithelial cells with the excimer laser and then the laser is used to change and reshape the cornea according to the refractive error the patient suffers from. The TransPRK procedure itself is done in a very short time with minimal manipulation of the eye – this leads to less discomfort and greater surgery success rates for patients.
Photorefractive Keratectomy or PRK eye surgery is recommended for patients who are:
● Over 18 years old
● Not pregnant at the time of the procedure
● Suffering from myopia with dioptres between -1.00 and -12.00
● Suffering from a stable refraction error – it has not changed for at least 12 months
● Patients with a complete understanding of the procedure and its results
● Patients who have a pupil that’s 6 mm or less
PRK surgery is also recommended for patients suffering from hyperopia or astigmatism.
TransPRK is a type of refractive procedure so you will need to go through a few tests to determine if you are suitable for this procedure in order to correct your astigmatism or short sightedness. Once you’ve decided upon a date for your surgery, preparing for it is easy.
You should not wear contact lenses for at least 2 days before the surgery and if you have toric contact lenses for astigmatism, you should stop wearing them for at least 4 days before the procedure. If you use hard gas permeable lenses, you should not wear them for at least a week before the surgery. Two days before the surgery, you will be provided with 2 types of eyedrops – you should apply these at least 4 times a day – the eyedrops contain anti-inflammatories and antibiotics in order to prevent inflammation and infections of the cornea.
Once the procedure is done, your vision will greatly improve but some blur may still exist because the surface cells called Epithelium need to regenerate and heal on the corneal surface. A very thin transparent contact lens will be placed over the eye upon finishing the surgery – this is in order to protect the cornea and speed up the regeneration of the epithelial cells. Your vision will continue to improve over the course of the next week and you will be able to see the full results of the surgery at the end of this period – after one month, your vision will be excellent. The thin protective contact lens creates a discomfort free recovery period and also the setting for a healthy, natural healing of the cornea.

When the body is young, the eye can focus perfectly at distant or near objects. This is due to the flexibility of the natural lens of the eye. With age, the eye loses this elasticity and flexibility and we experience a decline in the ability to focus on near objects.
Generally, people over 40 begin to notice slight problems when trying to focus on near objects such as book, newspapers or labels. This is a common ageing process known as Presbyopia – the deterioration of reading or near sightedness and reliance on reading glasses.
PresbyMAX is a laser vision correction technique that can correct any errors in far and near vision simultaneously. The technique was created to help people that rely on bifocal glasses, distance glasses, reading glasses and even progressive glasses.
The PresbyMAX technology significantly improves near vision of presbyopic patients – the surgery helps the cornea enlarge the depth of focus and minimises any contrast losses. Laser treatment of existing astigmatism, hyperopia or myopia can be combined effectively with presbyopia in order to reach the desired result. The technique provided patients with excellent results and clear, near-perfect vision without the need of contact lenses or glasses within just 2-3 weeks from the surgery. PresbyMAX has been used extensively over the last few years and the clinical data collected after the laser surgery is very encouraging for patients.
Presbyopia treatment is recommended for patients over 40 who rely on glasses or contact lenses for reading purposes, and still have trouble in focusing on smaller objects or text.
PresbyMAX can be performed on both eyes at the same time - the procedure itself takes around 10 minutes to complete and after that the patient can return home. The patient may return to normal activities and work from the next day.
After a few weeks you can resume activities such as driving – no injections are required and there will be no pain, but you will need eye drops. PresbyMAX is a very quick, comfortable and safe procedure. For reading, you can use a reading lamp to get the best possible results.
Tube lights are not recommended for reading, due to their flicker. You should also use sunglasses in bright sun as they will make your eyes more comfortable during the first few months after the surgery. By using the lubricating eye drops regularly, your eyes will be more comfortable and make your vision sharper.
Overnight stay is not required
The complete treatment of both eyes takes about 60 seconds
