LASIK Eye Surgery & Treatment

Refractive surgery is the term used to describe surgical procedures that correct common vision problems like nearsightedness, farsightedness, astigmatism and presbyopia. This vision correction procedure will reduce your dependence on prescription eyeglasses and contact lenses. LASIK is the most popular refractive laser eye surgery performed in Dubai. Over the past 25 years, surgical techniques, tools, and procedures for vision correction have evolved rapidly. The ophthalmologists at Quirónsalud use laser techniques like Intralasik, iLasik and PRK/Lasek. Our Lasik eye specialist doctors will make a comprehensive review of your eye conditions before advising on the most appropriate procedure.

About Refractive Problems
Published estimates based on epidemiological studies indicate that myopia affects 1.89 billion people worldwide, and, if the current prevalence rates do not change, projections show that it will affect 2.56  billion people by 2020.

Myopia and high myopia is estimated to affect 27% (1893 million) and 2.8% (170 million) of the world population, respectively, in 2010.

A Singaporean survey found the mean cost of myopia approximately USD$709 per person per year.

It is estimated that about 153 million people around the world are visually impaired because of uncorrected refractive errors. It seems that these errors are the commonest cause of visual impairment and the second leading cause of treatable blindness.1

Poor vision may influence the child’s performance in school and has a negative impact on his or her future life in terms of affecting the child’s personality.1

A recent screening conducted in Dubai private schools revealed that the common error of refractions identified among the sample were myopia (9.8%), hypermetropia (4.8%) and astigmatism (43.9%).1

The most significant preventable risk factor for visual disorders in children is maternal smoking. Children of women who smoked cigarettes during pregnancy have higher rates of strabismus, hyperopic, and astigmatism.

Myopia in children has been significantly related to lower consumption of protein, fat, Vitamins B1 B2 and C and iron, besides the cholesterol factor as well as less exposure to sun.

FAQs
Are the surgeries painful?

All our surgeries are performed under anesthesia so the patient don’t have pain at all and the time of performance is very short. Laser surgeries or lens implantations don’t require aggressive anesthesia. The refractive surgeon will assess you about this.

When will I recover my vision for normal performance?

Depending on the procedure can be different, but most of our cases recover good vision in some hours to 2 or 3 days. In very few cases, can be later but the refractive surgeon will tell you before.

Are the results forever?

Myopia can increase with the time but very low frequency and amounts. If you need glasses again with the years, in most of the cases you can have an enhancement but this situation is very unusual

Are there any possible complications?

Refractive surgery is performed worldwide and is considered a safe surgery. It is normal to have some light disturbances as dry eye sensation, visual adaptation, sensibility to light, night halos or brighter lights during the first days. All of them tend to decrease with time. Severe complications are avoided with proper patient selection, correct surgical indication and adequate postoperative care. The refractive surgeon will explain it in detail before the surgery.

Can I become myopic again if I got pregnant?

Normally, pregnancy doesn’t increase myopia. In the unusual case of increases due to the evolution of pregnancy, they tend to be small and most of them return to the previous state after the birth.

What if I am pregnant now? 

We advise all pregnant woman to wait some months after the childbirth to have refractive surgery

Why LASIK Surgery Is Right for You?

Before you decide to have LASIK surgery, visit one of our eye specialists at Quirónsalud to talk about whether or not it is the right procedure for you. LASIK eye surgery might not be the best option if your eye glasses or contact lens prescription is still changing. People with thin corneas or with certain medical conditions, such as dry eyes, might not be good candidates for LASIK surgery either.

Our LASIK Center in Dubai

We offer a full range of corrective eye surgery procedures that are best suited for every pair of eyes. Our ophthalmologists are highly qualified LASIK eye surgeons in Dubai.

IntraLase

IntraLase is a new state of the art laser treatment that prepares the LASIK corneal flap by using a femtosecond laser. Usually, LASIK treatments use a mechanical device called a microkeratome which uses a blade to produce the LASIK flap. IntraLase is a “no blade” procedure a flap which is much more precise in depth, is cleaner, more accurate and is thinner.

Benefits of IntraLase Treatment Flaps

The primary benefit is that all suitable prescriptions can now be treated with bladeless technology, thus eliminating the induced distortion and possibility of serious complications associated with the creation of the flap by the manual blade. More patients achieve 20:20 vision or better; fewer patients lose the sharpness of vision. Both short term and long-term safety are improved upon. Increased confidence for both the doctor and patient lessens stress and anxiety. Both mechanical breakdown and human error are reduced.

How is PRK performed?

Initially, your eye surgeon will remove a central area of the corneal epithelium with an alcohol solution or a blunt surgical instrument. After this process, an excimer laser is used to precisely reshape the curvature of your cornea’s surface. The laser is computer-controlled and highly specialized which delivers pulses of cool ultraviolet light that remove microscopic amounts of tissue with precision. Later, a soft contact lens bandage is placed on the cornea to protect the eye. New epithelial cells grow back in about four to five days, after which the ophthalmologist removes the bandage contact lens.

LASIK Treatment FAQ’s

Are LASIK and PRK safe procedures?

Laser vision correction uses a cool non-thermal beam of light that is computer controlled. Many safeguards are in place to reduce the risk of error.

Can I have both eyes done at the same time?

Most surgeons perform a LASIK procedure on both eyes at the same time. It takes longer for clear vision after PRK so many surgeons will wait a week or two between eyes for PRK.

Does laser vision correction hurt?

You won’t feel any pain during LASIK or PRK because your surgeon will place anesthetic eye drops in your eye before the procedure. He or she may prescribe pain medication after the procedure if necessary.

How long does LASIK take?

The laser treatment takes less than a minute, but the entire procedure takes about 10 minutes.

Are there any side effects?

There are not many side effects, but some people may experience dry eye after LASIK, which can be relieved with eye drops does not last long.

LASIK

The LASIK surgery technique is currently the most widely used for the correction of refractive defects and is fully consolidated after more than 25 years in Dubai and worldwide. The main indications are myopia, hyperopia or astigmatism.

In the LASIK technique, a superficial corneal flap is lifted, and the excimer laser is applied for seconds to the superficial layers of the cornea, in order to reshape its curvature and be able to have clear vision.

In total, the operation lasts about 10 minutes and will be followed by a short rest period in the clinic, which the patient must pass before being able to go home.

iLasik Intralase

iLasik Intralase is the result of the refinement of the technique and it combines all of the latest LASIK technology in one efficient procedure. As any LASIK technique, we create a superficial corneal flap and the excimer laser is applied under it but it has some improvements.
The iLASIK Intralase procedure provides better visual outcomes due to:

  • Custom Vue analysis modifies laser pattern for better night vision.
  • LASIK Intralase enhances safety and predictability of flap creation.
  • Iris Registration ensures sharper vision by optimizing the placement of the laser treatment in a personalized laser vision correction procedure
What is the LASIK-INTRALASE technique about?

A corneal lamina of 100 microns thick is lifted with the extremely precise INTRALASE. This technology allows us to create a soft and regular surface that provides optimal healing conditions.Once we have the corneal flap created, we lift it softly to uncover the corneal plan where we apply the EXCIMER LASER. This laser reshapes the corneal curve in order to get the images focused. The EXCIMER LASER pulses have micron fraction precision.

After some seconds, the EXCIMER LASER finishes and the surgeon replace the corneal flap back on the cornea. No suture is needed. Only some caution for the patient so as not to brush or close strongly the eyes for some days.

PRK/LASEK

The operation with surface techniques (PRK/LASEK) consists of the separation of the epithelium, which is the most superficial layer of the cornea, using a special solution or a brush. In this case a corneal flap is not made.Once the corneal epithelium is removed, the EXCIMER LASER is applied to correct the curvature of the cornea and to correct diopters as we do in iLasik procedures.

After that, we cover the cornea with a therapeutic contact lens for a few days to let the epithelium heal. The recovery is delayed compared with LASIK but the final results are comparable.

PRK-LASEK is indicated for myopia or astigmatism in certain conditions to perform refractive surgery safely, mainly in persons with thin corneas or who practice contact sports.

Phakic intraocular lenses (ICL)

Patients with high myopia, hyperopia and astigmatism, thin corneas or low vision despite the best possible optical correction, we can get better results by implanting a flexible epicapsular lens compared with LASIK.

The intervention is performed under topical anaesthesia (drops), it takes around 5 minutes, and it is not necessary to patch the eye after surgery. The vision is recovered very soon.

Flexible epicapsular ICL lenses are able to correct up to 18 dioptres of myopia, and 8 dioptres of hyperopia, with or without associated astigmatism of up to 6 dioptres. For refractive impairment above this dioptre range, or in the case there is a residual refractive impairment, which is very rare, the patient may undergo a refractive adjustment procedure using the LASIK or PRK-LASEK techniques.

What is Presbyopia

Presbyopia is the main visual anomaly that affects people over 45 years. It happens when the natural lens of the eye loses part of its flexibility. This flexibility allows the eye to focus on different distances. Presbyopia is associated with aging of the organs and can not be prevented. Currently, we have very safe and effective surgical treatment to correct this problem.

When the eye is relaxed, it is also normally focused for far. No matter if the person is wearing glasses or not. When the person needs to focus a near object, the brain sends an order to some muscles around the lens to make it steeper. If we want to focus for far again, the muscles relax and the lens recovers its natural curvature. After 45 years old, the lens proteins start to become stiffer and despite the brain impulses, the lens doesn’t curve so much and there is a blurred near the image.

Presbyopia is progressive until 55 – 60 years old. The patient will have to use glasses or contact lenses to see nearby images. The amount of diopters needed will depend on the age and the working distance. Most of the presbyopic patients use reading or progressive glasses. With the increase in life expectancy, presbyopia prevalence will also increase. Around 80% of population over 45 years and almost 100% of those over 65 suffer from presbyopia.

Presbyopia Correction

There are several surgical techniques to treat astigmatism depending on the physiological characteristics of each patient but can be summarized in two kinds: implantation of a last generation multifocal intraocular lenses or laser treatments.Both techniques are aimed to eliminate or reduce the use of glasses and contact lenses for near distance, and also for far distance in the cases associated to other refractive problems.

It should be the ophthalmologist who, after a complete eye exploration and considering personal expectations, must indicate which type of operation is most appropriate for each case.

FAQs About Presbyopia

Can presbyopia be prevented?
All people will develop presbyopia sooner or later. Presbyopia can not be avoided, but certain measures can be taken to reduce the symptoms, as using glasses once the symptoms begin, work in optimal light conditions or take some breaks when working on the computer.What is the best age to have presbyopia surgery?
At any time if you have become high dependent on glasses or contact lenses for your daily life. There are diverse circumstances such as age, professional activity or associated visual problems that can cause greater discomfort. Each person is different and their motivations are different.If I have surgery for my presbyopia, will it stop or will it develop again?
If presbyopia is corrected with a multifocal intraocular lens, the new lens will not lose the focus ability. In case of laser correction, the presbyopia can be fully corrected but with the time, as we keep the eye lens, some amount of presbyopia can develop when aging. Despite this, some cases may benefit more of laser procedures rather than with intraocular lenses. The refractive surgeon will advise the best procedure for each individual case.

If I have surgery for my presbyopia, will I develop cataracts?
If presbyopia is corrected with a multifocal intraocular lens, we can also correct other refractive problems (myopia, farsightedness and/or astigmatism) and, as we change the eye lens, the patient will not develop cataracts when older. In case of laser correction, cataracts can develop as we keep the eye lens. The refractive surgeon will advise the best procedure for each individual case.

What is Myopia

Myopia is a problem of refraction manifested when the patient perceives fuzzy far objects with nearer than normal vision due to a longer than normal eye or because the cornea, the lens or both are too powerful.

Despite the bad far vision, myopia is not a disease in most of the cases. The patients develop normal life but they must wear glasses or contact lenses at any time. Only in some cases, myopia is related to bad vision due to anatomical problems, normally in cases with high number of diopters.

Symptoms of myopia may occur from infancy and may increase over time as changes in graduation occur. As a rule, myopia tends to stabilize from the age of 18 years and once the evolution has stopped, further increases are very spare. It may present with other refractive defects, such as astigmatism (myopic astigmatism) or presbyopia.

 

Types of Myopia
Two types of myopia are usually distinguished: simple myopia, which is usually less than 6-8 diopters and the patients keep good corrected vision. On the other hand, and due to excessive elongation of the eye is myopia magna, high myopia or pathological myopia. Such bigger than normal eyes can develop degenerative changes of ocular tissues, mainly at retina, that can lead to low corrected vision.Simple myopia is the most common type of myopia and can’t be prevented, although it should be detected in time through a complete ophthalmological examination and corrected by the use of glasses, contact lenses during evolution, and once it is stabilized, myopia can be eliminated with refractive surgery.
Myopia Correction

There are several surgical techniques to treat myopia depending on the physiological characteristics of each patient but can be summarized in two kinds: laser techniques and intraocular lenses implantation.

It should be the ophthalmologist who, after a complete eye exploration and considering personal expectations, must indicate which type of operation is most appropriate for each case.

FAQs About Myopia

Can myopia be associated to other refractive problems?
Myopia may appear alone but normally is associated to astigmatism. Myopic patients also develop presbyopia during their 40s. A person can never have both myopia and farsightedness because they are opposite. The association of myopia with other refractive problems is not a problem for refractive Surgery because all the problems can be arranged with the diverse techniques available today.

Is there any diopter limit for myopia correction?
The correction limits with laser surgery are usually 8 to 10 diopters of myopia. These limits may vary depending on the characteristics of each patient. For higher amounts of myopia, an intraocular lens should be implanted. It should be the Refractive Surgeon that assesses whether or not a patient is a good candidate for refractive laser surgery and which technique should be applied in each case during the preoperative consultation.

Is myopia a genetical disorder?
Myopia has a very important familiar background but some personal factors may influence.

What is Hyperopia

Hyperopia or farsightedness is when a patient has blurred and uncomfortable vision at close range, although, from a certain age, far objects are also seen blurred. It is caused by a shorter than normal eye or because the cornea, the lens or both are less powerful than average.

Some early-onset cases are associated with strabismus (ocular misalignment) and amblyopia (low vision in one eye). During the first decades, most patients can compensate this natural defocus with an extra effort with the lens but they can complain of headaches and blurred vision after some time, especially when reading. This can cause school delay.

Hyperopia affects most of the newborns since its visual system is not yet fully developed (physiological hypermetropia), but during the period of growth tends to be corrected. Hyperopic patients tend to have refractive surgery earlier than myopic ones.

 

Hyperopia Symptoms

The main symptom of farsightedness is that the patient perceives fuzzy objects nearby, although this signal may not appear or be attenuated if the patient is young and retains his ability to accommodate. Other possible indicators of hyperopia can be: headache, eye pain, eye fatigue, school delay …

Early onset cases are associated to high hyperopia and can cause strabismus and amblyopia. These cases should be referred to a strabismus ophthalmologist (squint) as soon as they are detected. Early treatment can recover the lost vision and improve the visual outcome. Ignoring this signs, can limit adult vision.

Hyperopia Correction

There are several surgical techniques to treat hyperopia depending on the physiological characteristics of each patient but can be summarized in two kinds: laser techniques and intraocular lenses implantation.

It should be the ophthalmologist who, after a complete eye exploration and considering personal expectations, must indicate which type of operation is most appropriate for each case.

FAQs About Hyperopia

Can hyperopia be associated to other refractive problems?
Hyperopia may appear alone but normally is associated to astigmatism. Hyperopic patients also develop presbyopia during their 40s although the symptoms are similar. A person can never have both myopia and farsightedness because they are opposite. The association of hyperopia with other refractive problems is not a problem for Refractive Surgery because all the problems can be arranged with the diverse techniques available today.

Is there any diopter limit for hyperopia correction?
The correction limits with laser surgery are usually 3 to 4 diopters of hyperopia. These limits may vary depending on the characteristics of each patient. For higher amounts of myopia, an intraocular lens should be implanted. It should be the Refractive Surgeon that assesses whether or not a patient is a good candidate for refractive laser surgery and which technique should be applied in each case during the preoperative consultation.

Is hyperopia a genetical disorder?
Hyperopia has a very important familiar background but some personal factors may influence. Many patients report similar familiar cases.

I have always had farsightedness and I have seen evil from close up, but now I am beginning to see evil from far without glasses. Why does this happen?
Farsightedness usually affects the vision of nearby objects. Many hyperopic patients keep good uncorrected far vision meanwhile the lens is young and only use glasses for near activities (reading, computer, etc.). As we get older, it is quite common that it also begins to affect the vision of distant objects due to lens increasing rigidity.

What is Astigmatism

Astigmatism is a refractive problem that occurs when the eye refractive surfaces (mainly the cornea although can be the lens or the even the eye shape) does not have the same curvature in all its areas. Can be associated to myopia or hyperopia.

This curvature difference makes that light entering the eye has no focus point but a stretched focus zone that produces a blurred image.

The main symptom of astigmatism is the blurred or distorted perception of both distant objects and nearby objects. It is also common the difficulty to perceive small details at all distances. In cases where astigmatism is associated with farsightedness, it is common for the patient to suffer visual fatigue, itching redness and stinging of the eyes, dizziness or headaches due to the overexertion of the eye to focus the images.

 

Types of Astigmatism

Simple (It affects only one axis), compound (Associated with myopia or farsightedness) and mixed (One axis is focused in front of the retina and the other axis behind). It all depends on the eye shape and size.

Those associated with myopia usually increase with the growth. The others tend to be less evolutive. As all the other refractive defects, astigmatism can be operated when demonstrates stabilization.

Some astigmatisms are related with ocular pathologies (mainly keratoconus). We must suspect this disease in case of a progressive evolution and decrease of vision. With a deep ocular examination, these cases should be diagnosed and refractive surgery must be avoided.

Astigmatism Correction

There are several surgical techniques to treat astigmatism depending on the physiological characteristics of each patient but can be summarized in two kinds: laser techniques and intraocular lenses implantation.

It should be the ophthalmologist who, after a complete eye exploration and considering personal expectations, must indicate which type of operation is most appropriate for each case.

FAQs About Astigmatism

Is there any diopter limit for astigmatism correction?
The correction limits with laser surgery are usually 6 to 8 diopters of astigmatism. The key for all astigmatism treatment is to reject for surgery all the cases related with ocular pathology, as keratoconus or astigmatism associated with corneal scarring. In case of corneal pathology, an intraocular lens can be implanted once we have checked the refractive stabilization

Is astigmatism a genetical disorder?
Astigmatism has a very important familiar background but some cases are related with corneal disease (keratoconus) or corneal scarring (corneal herpes, accidents,…).

How is its evolution?
Astigmatism is usually the most stable of all refractive problems. When associated with myopia, usually there is more evolution in the myopic part than in the astigmatic part. When associated to hyperopia or in mixed astigmatism, the evolution is very small. If it increases slightly, it is common to stabilize at 20-25 years.

Can astigmatism be prevented?
Astigmatism can not be prevented, but it can be detected through a complete ophthalmological examination and subsequently corrected by the use of glasses, contact lenses or different types of surgical techniques.

Is the surgery more difficult if I have another problem associated with astigmatism?
No, it isn’t. With the current laser surgery or with the available lenses, we can treat all the refractive problems a patient have with the same excellent results. It should be the Refractive Surgeon that assesses whether or not a patient is a good candidate for refractive laser surgery and which technique should be applied in each case during the preoperative consultation.
