Questions about Presbyond
What happens if I can’t get used to the vision after Presbyond?
Presbyond laser vision correction can be reversed with a 2nd laser treatment.
How do I know if Presbyond will work for me?
A detailed ophthalmic assessment would be carried out to assess whether a not you can adapt Presbyond. Most people have no difficulty adapting to Presbyond vision.
Is Presbyond the same as multifocal implants surgery?
No. In Presbyond natural lens is left in place in the surgeon does not enter into the eye. The procedure is carried out by laser on the cornea.
What if I have Presbyond and later develop cataracts?
Having Presbyond surgery in no way affects cataract surgery if it is required at a later time. After the cataracts are removed the vision should return to normal and you should remain independent of glasses.
Questions about SMILE
Can I engage in contact sports after SMILE?
Yes, the cornea is stronger and there is no flap that might get displaced if there were a direct trauma to the eye.
How much time off work would I need if I have SMILE vision correction?
The preoperative assessment usually takes about 2 hours and your vision will be a little blurry until the drops wear off. This takes normally 6 to 8 hours. Many patients return to work the day after the surgery itself but many prefer to treat themselves to a little time off.
Can I have both eyes treated at the same time?
Yes. It is usual for both eyes to be treated at the same session.
How long does it take for my vision to become clear?
The vision is clear immediately and continues to improve in the days afterwards.
I am an organ donor and if I have laser vision correction would this mean that I cannot donate my eyes after I die?
Laser vision correction does not prevent the eyes being suitable for transplantation.
Questions about LASIK
Is Lasik still used today?
Lasik still has some applications today but the advantages of SMILE mean that it is the treatment of choice for the majority of patients. Presbyond is a modification of Lasik.
Questions about PRK
Is PRK still used today?
Photo Refractive Keratectomy, or PRK, is rarely used today but there are occasionally situations where it has advantages. A variant, Photo Therapeutic Keratectomy, is frequently used to treat an uncommon condition called recurrent erosion.
Questions about Paediatrics
I had a squint as a child, should I get my child checked?
Squints are often hereditary so that it is important to have your child checked as early as possible either if parent had a squint.
I have a lazy eye, should I get my child checked?
Yes, having a lazy eye can be inherited. Have your child checked as early as possible.
What can I do to avoid my child needing glasses?
Emerging evidence is beginning to show that spending time outdoors in the very early years of life protects against developing myopia. What the child does outdoors doesn’t matter, just being outdoors is enough.
Questions about Cataract Surgery
How active can I be after my cataract operation?
You should take things easy for the first few days. You may bend and stoop but it is probably better to avoid heavy lifting for about ten days. You may wash your hair. The greatest danger is poking or rubbing the eye, as this can cause the valve to open, making the wound leak. Because some people rub their eyes in their sleep, we advise you to wear a protective shield (provided by the clinic) at night in bed for the first week only. After this time, you may gradually get back to full normal activities.
Can cataracts come back after surgery?
Once a cataract has been removed, it cannot recur. However, the fine membrane on which the implant rests can occasionally become cloudy, causing the vision to deteriorate again. If this happens, we can remove the cloudiness with a laser. This is done in the outpatients department; the treatment is painless and takes about 2 minutes. There is a misconception among some people that this laser can remove a whole cataract; it cannot, but it can remove the cloudiness that sometimes comes after the operation.
When can I drive after a cataract operation?
Most patients’ vision is adequate to drive the next day. Many patients prefer to rest for the first few days.
When can I wash my hair after cataract surgery?
Within a few days.
When can I bend and stoop after my cataract operation?
The self-sealing incision allows patients to bend and stoop straight away.
When can I fly after cataract surgery?
What should I do if complications arise after my cataract operation?
Call us immediately and tell us what you feel is wrong. We will see you immediately if necessary. We can be contacted 24 hours a day every day.
What happens if I move during the cataract operation?
Many people worry about this, but it is not a problem.
Is surgery the only way to treat a cataract?
Just because you have a cataract does not mean that you have to have it removed. Cataract surgery only becomes necessary if you are not happy with your vision and want to see better. Talk to your doctor if you have any questions or concerns about your vision.
Does cataract surgery hurt?
Thanks to numbing drops, this procedure involves minimal discomfort.
Will I be asleep during my cataract operation?
Since this procedure does not take very long, it is not necessary to put you completely to sleep with general anaesthesia. Instead, your surgeon will use a local/topical anaesthetic to numb your eye and you will remain awake during the surgery.
How long will I be in the hospital after my cataract operation?
Patients commonly spend only a few hours at the hospital or surgery centre, and are allowed to go home the very same day.
How long will my vision take to return to normal?
Every patient and every eye is different, but patients commonly see well enough to drive the day after receiving cataract surgery. Ask your doctor how quickly he or she expects you to recover.
Are there any risks of having cataract surgery?
While cataract surgery is very safe, there is a risk of an infection getting in the eye. This can generally be treated effectively with antibiotics if it is noticed in time. There are also some small risks of retinal detachment or waterlogging. We strongly believe that living with cataract is far more dangerous than having the operation itself.
Can the cataract lens be replaced if it doesn't work?
Although this would be unlikely, the IOL can be replaced with a different one if needed. Ask your surgeon how they would handle this situation.
What precautions should I take after my cataract operation?
Every patient is different, so be sure to ask your doctor for advice on caring for your eye after the procedure. Your doctor may ask you to refrain from rubbing your eye or engaging in any strenuous activity for a few weeks after surgery.
Questions about Glaucoma Treatment
What happens if the pressure in the eye does not fall below my target pressure?
There is a much greater risk of losing vision.
What does target pressure mean?
It is the pressure below which further damage to the vision is unlikely.
How do I find what my target pressure is?
The ophthalmologist looking after your case will work out what your target pressure is by assessing your eye and family history.
How do I know if the treatment is working?
Your ophthalmologist will tell you when the target pressure is achieved.
Can I live a normal life with glaucoma?
Yes. There are no restrictions on lifestyle.
I have glaucoma. Should my family be checked?
Yes. People with a close relative with glaucoma have a slightly increased chance of developing it themselves.
Questions about Macular Degeneration
What are the risks of getting macular degeneration?
Macular degeneration affects mostly older people and its incidence increases with age. About three people per 1000 over the age of 50 will develop macular degeneration.
It’s very rare in young people and it is usually due to an inherited abnormality.
Are there different types of macular degeneration?
Yes. There are inherited macular degenerations which affect mostly younger people but these are very rare. Most macular degeneration is categorised as “age-related” meaning that it occurs mostly in older people. In the age-related group there are 2 main types, dry and wet. The wet type is so-called because fluid leaks out of the blood vessels at the macular and this damages vision. However there is an effective treatment for wet type macular degeneration which involves injecting a drug into the eye. The dry type is characterised by a process best described as “wearing out” of the retinal cells at the macular so they no longer are able to see. Currently there is no effective treatment for the dry type.
What is the treatment for macular degeneration?
A group of drugs known as anti-vegF can reverse and improve wet macular degeneration. Currently, there are three different brands of these drugs, two of which are licensed. These are Lucentis and Eylea. Because they have been through the regulatory process they are far more expensive. Another drug of the same group known as Avastin is equally effective and equally safe. However it is not been through the regulatory process and therefore is much cheaper.
Can macular degeneration cause blindness?
Macular degeneration damages the central vision only. However, the central vision is very important and is the vision that allows us to read and to see fine detail. One way to imagine what it would be like to have macular degeneration is to remember the effect of someone taking your photograph with the flash. In the seconds after the camera flash you can see a black spot in the centre of your vision that moves around as you try to look about. Imagine a much larger black spot but instead of wearing off in a few seconds it’s permanent. This is the effect of macular degeneration. People who suffer from macular degeneration will always have enough vision to get about and will never be completely in the dark. However they may not be able to read or drive or to see the fine detail that they enjoyed previously.
Is there anything I can do to reduce my risk of developing macular degeneration?
Macular degeneration is more commonly seen among smokers and in people who have a poor diet. Diets rich in dark leafy vegetables such as spinach or kale contain nutrients that are believed to protect against the disease. Some practitioners advocate the use of supplements in the form of tablets but the evidence for their efficacy is very scant.
Questions about Myopia Control
How do I know if my child may have myopia?
If your child has myopia you may find that they have trouble seeing things from a distance. You may find that they sit too close to the television, squint or don’t pay attention in school because they can’t see the board from where they are sat. They may also complain about having headaches or tired like eyes when they are trying to focus on something from far away. Don’t ignore these signs and think they are just habits of children, early recognition and care can have a significant impact on the health of your child’s eyes.
Can myopia be cured?
Currently there is no cure for myopia. It’s a refractive error caused by the eyeball growing too long during childhood. When this occurs light entering the eye fails to form a clear focus on the light-resulting in blurry distance vision.
Can myopia be controlled? How?
Yes, there are proven methods that can be prescribed by an eye doctor to slow the progression of myopia during childhood. My iClinic will be introducing myopia control methods such as specially designed contact lenses contacts that are worn during the day in order to temporarily reverse myopia by reshaping the cornea. There will also be the option of low-dose atropine drops. Atropine has the power to slow down the progression of myopia and children all around the world have begun to receive treatment in clinics that have the drops. The lenses and drops that we prescribe can correct the blurry distance vision cause by myopia and relieve associated symptoms of myopia such as headaches, eye strain and squinting.
Will myopia control hurt my child?
No! As your child may be new to contact lenses or eye drops, sometimes there can be discomfort while he/she gets used them, this is natural. Over time they will become more comfortable with the treatment.
Are there any risks associated with low-dose atropine?
A study was undertaken to see if low-dose Atropine would influence the progression of myopia in young children, the children who took part in the study showed no side effects which furthermore proves that low-dose Atropine may be a solution to help slow down the progression of myopia in your child’s eye.
Will my child need an eye exam before starting treatment?
If you believe your child may be suffering from myopia you will need to schedule a consultation with our specialist. During this consultation, your child’s eye will be examined and you will be discussing the best course of treatment for your child as recommended by the consultant from the test results.
Do I need to bring anything to the appointment?
If you have any letters from previous clinicians then do please bring them along, other than that we just need the patient and any glasses they may wear.
