+ What cause cataracts?
+ Do cataracts lead to blindness?
Early cataracts may decrease the distance vision, while the near vision remains normal. As the cataract progress the vision deteriorates, but does not necessarily cause blindness.
+ What's the treatment for cataracts?
+ How is cataract surgery performed?
+ Can a cataract develop again?
Once a cataract is removed it will not develop again. At a later stage you may experience a decrease in vision, which is due to opacification of the lens capsule. The capsule supports the intra-ocular lens in the eye. This can be treated with a laser, at the consulting rooms of the doctor.
+ Are there any restrictions after surgery?
After the operation you may go home as soon as you feel comfortable. Driving is restricted for the first few days aftersurgery, but you may resume other normal activities. Special care should be taken not to press on or rub the eye during the first week after surgery.
+ Is cataract surgery always successful?
Even if the surgical removal of the cataract was uncomplicated, the vision after surgery may not be perfect. This is usually due to changes in the retina of the eye. The retina is the equivalent of a film in a camera. If the film is damaged a clear picture is not possible even if new lenses are added to the front of the camera. It is at this stage unfortunately not possible to treat some of the changes in the retina which older people experience, for example disciform macular degeneration or calcification of the retina.
+ Are different types of Glaucoma?
Yes, there are many different types, but there are two major types: Chronic and Acute. Chronic open angleglaucoma (COAG) is the most common form of glaucoma. In COAG the entrance to the drainage canals is open, but there is a clogging problem inside the drainage canals. The disease is slow, causes gradual loss of small patches of vision, it is a lifelong condition and responds well to medication and surgery.
+ Does Glaucoma run in the families?
Yes, if one parent has COAG the chances of children getting Glaucoma is 10 times greater than in a non-glaucoma family.
+ How i Glaucoma treated
Generally speaking, glaucoma cannot be cured, but it can be controlled. Once diagnosed, it requires constant, lifelong care. The major goal of glaucoma treatment is to keep the eye pressure in a range that prevents further glaucoma damage. This can be done with eye drops, pills, laser treatments and microsurgery.
+ What advise is there for Glaucoma patients
Follow your eye specialist's instructions, use medications regularly, know what your medications are, know their side effects, tell your doctors that you have glaucoma and what medications you are using, call your eye specialist about any unusual changes in your eyes or vision, go for regular check-up's.
+ What is retinal detachment?
A retinal detachment is a separation of the retina from the back wall of the eye. When there is a tear of the retina, liquid from the vitreous may pass through the tear, and detach/pull off the retina. As the fluid accumulates, the retinal detachment becomes larger. Detached areas of the retina lose their vision.
+ What are the symptoms of a retinal detachment?
Most people notice floaters and flashes before the retina detaches. As the detachment occurs, a gradually enlarging dark area may be seen. Some people have compared this to a curtain coming down, or a shade being drawn in front of the eye. The dark area may begin in any part of the field of vision. If the dark area reaches the centre of the field of vision, the eye will not be able to see fine detail.
+ Who may get a detached retina?
Although anyone may get a retinal detachment, they are far more common in some groups. These include short sighted people, those over 50, those who have had significant eye injuries, and those with a family history of retinal detachments.
+ How are retinal tears and detachment treated?
Retinal tears with minimal or no detachment may be treated with laser or freezing (cryopexy) procedures. Mostretinal detachments require surgery to reposition the separated retina against the back wall of the eye. There are several methods in use today. The type of surgery used depends on the type and extent of detachment, and the
+ Will I get my vision back?
With current methods, most simple retinal detachments can be repaired. Repeat surgery may often be required for more complex retinal detachments. Because the detachment may damage the retina, most people do not get back perfect vision. If the macula (the central, most sensitive part of the retina) was not affected by the detachment, about 2 out of 3 eyes will get back reading vision. If this area was affected, only about 1 out of 3 eyes will get back reading
+ What is wavefront technology?
There are two main types of wavefront technology used in LASIK. Customised wavefront laser is treatment individualised to your eye after measurements are done on an instrument called a wavefront analyser. This can correct tiny imperfections in the eye and may be required for eyes that have a large amount of higher order aberrations. Wavefront Optimised laser is a treatment which has been designed to minimise aberrations induced and it is the technique we use on most patients. Both these techniques have improved the quality of vision as compared to conventional LASIK and help to minimise night glare and halos.
+ Are all excimer lasers the same?
Like every procedure, refractive surgery changes all the time.
+ Is laser equipment regulated?
The excimer laser is a sophisticated piece of equipment. It is manufactured overseas. In the USA a device has to undergo rigorous testing and clinical trials to establish the safety and effectiveness before it can be FDA approved. The laser we use is FDA approved. We have a maintenance contract to ensure that the laser is compliant with all regulations and is safe and accurate at all times.
+ Is lasik painful?
Most patients do not find the procedure painful at all. Some do find it a little uncomfortable or have a feeling of "pressure". It is over very quickly. For most patients the fear of the unknown is worse than the actual procedure. Anaesthetic drops are used to numb the eye just before surgery begins and you may wish to use a mild sedative.
+ How long does lasik take?
Numerous checks are done before you are escorted into the laser theatre. Once you are in, the procedures will be completed in 10-20 minutes.
+ What will my recovery be like after the procedure?
Most LASIK patients see well the day following surgery and usually will be able to resume most of their normal daily activities. Patients with high prescriptions may recover more slowly. PRK patients also heal more slowly. The speed of recovery can vary between patients.
+ Are both eyes treated?
Most patients prefer to have both eyes treated at the same time. However you do have the option of treating them on separate days should you so wish.
+ What are the risks of lasik procedure
Almost everything you do in life has risks. All types of surgery have some degree of risk and refractive surgery is not excluded. However, the chance of having a serious vision reducing complication has been documented in a number of clinical studies to be very low. LASIK and PRK have been around for many years and countless studies have been done to improve the results and safety. Millions of people have had excellent results. Thus it is one of the most common operations done the world over. Some potential complications include conditions such as dryness, complications in making the surgical flap, night glare, under or over-correction, ectasia and loss of best-corrected vision.
+ Can I go blind after surgery?
Realistically there is no real chance of this (some say there is perhaps a chance of about 1 in 5 million – the same risk as dying in a plane crash).
+ How good will be my vision after the Lasik surgery
While laser vision correction has proven overwhelmingly successful in reducing dependence on glasses and contact lenses, the degree of improvement may vary among individuals. How well and how quickly your vision improves depends on how well you heal and the severity of your prescription.
+ What is monovision?
Monovision is an option where one eye is corrected for distance and the other for near vision. This arrangement suits some although most people prefer to have both eyes corrected for distance. Monovision is subject to individual adaptation. Should you be in the presbyopic age group (i.e. over 40 years) and wish to consider this, you would need to try it out with a contact lens trial to see if it suits you. Your optometrist can arrange this for you.
+ How soon after the procedure can I drive?
Most people have vision that is legal for driving without glasses the day after surgery. PRK patients take longer. Your vision is tested the day after surgery and we can inform you if you are indeed legal.
+ Do I need to take time away from work?
Usually you can return to work the day or two after your procedure. PRK patients may need to take a week off work.
+ Will my vision be corrected forever?
We look at the stability of your prescription prior to planning surgery. If your eyes are stable there is an excellent chance that you will have permanent correction of your refractive error. However some patients’ eyes do change with time. Some patients may need to wear glasses for some demanding tasks (e.g. for night driving) and others may need a late enhancement.
+ Will I be able to wear corrective lenses after LASIK or PRK?
Most patients do not require any correction after their procedure. However you certainly can should this need ever arise. Contact lenses can be worn 6 weeks after the procedure.
