Frequently Asked Questions
WHY DO PEOPLE WANT VISION CORRECTION SURGERY?
There are several reasons why patients want freedom from glasses or contact lenses. Glasses often induce distortion of the peripheral vision as well as a prismatic effect peripherally which people find interferes with high level performance activities such as sport and driving. Also glasses often steam up or smudge giving patients glare and haloes and a reduced quality of vision. Prescription glasses are not very good at correcting significant levels of astigmatism and this will lead patients to have a suboptimal level of vision even with glasses on. People often misplace or break glasses which leads to frequent frustration. Contact lenses result in a different set of problems. Their prolonged use deprives the surface of the cornea of oxygen resulting in the growth of blood vessels into the cornea and occasionally scarring. They also desensitize the cornea resulting in dryness and break down of the surface of the cornea. Finally their use can rarely be associated with sight threatening infections.
WHAT IS DIFFERENT ABOUT VISION CORRECTION SURGERY TODAY?
The evolution of technology combined with a properly trained modern cornea and refractive surgeon’s skill have resulted in a quantum leap of safety and success with vision correction procedures. There is now plenty of long term (20 years or more) scientific data supporting the use of laser vision correction, implantable contact lenses or refractive lens exchange surgery in appropriately selected individuals. This data shows long safety as well as long term stability. If done appropriately vision correction surgery should be of permanent benefit for the patient. The risks of laser vision correction have now reduced so considerably that the lifetime risk of contact lens wear is greater than the one off risk of laser vision correction.
HOW LONG DOES THE BENEFIT OF LASER EYE SURGERY LAST? WILL I NEED TO HAVE IT DONE AGAIN?
Providing the patients are properly selected and treated appropriately by the surgeon the benefit of laser eye surgery should be permanent. There is a small chance that an enhancement will be required within the first 2 years. For most prescriptions Mr Barsam’s enhancement rate is only 1%. The enhancement rate can be higher than this for the less common high profile treatments and if this is the case then Mr Barsam will inform you of this during your consultation. In patients who are approaching the age when reading glasses become necessary, Allon Barsam offers his patients either laser blended vision or a refractive lens exchange with a multifocal intraocular lens depending on what each patient requires.
ARE THERE RISKS INVOLVED?
All medical and surgical intervention involves risk. In fact much of what we do in life such as driving a car or travelling by plane also involves risk. Surgical procedures are no exception to this and the risks of complications vary greatly depending on the training and skill of the individual surgeon as well as by the type of procedure being carried out. Each person’s eyes are different and the risks may not be the same for one person as they are for another.
If you are considering LASIK surgery for example, it is sensible to be educated and informed about any potential LASIK surgery risks before you begin treatment. When you meet with Allon Barsam he will take a great deal of time to explain to you what the risks and benefits and alternatives are for the procedure that you want so that you can make a fully informed decision about treatment.
All technology for laser eye surgery, refractive lens exchange and cataract surgery is very advanced these days. Despite this uncommon complications can occur during the time of the operation or in the post operative period. The skill of the surgeon is critical to ensure that in the unlikely event that problems arise they can be managed safely.
In Mr Barsam’s hands for patients undergoing Vision correction or cataract surgery the risk of a significant complication is very low.
