Which refractive errors can we treat with Eye Surgery?
- Myopia (short-sightedness). Please watch our illustration Myopia
- Astigmatism (blurred vision). Please watch our illustration Astigmatism
- Hypermetropia (long-sightedness). Our illustration on Hyperopia
Laser Eye Surgery uses pulses of invisible, ultraviolet light to remove a microscopic layer from the front surface of the eye, changing the curvature of the cornea ever so slightly. To correct nearsightedness, the curvature of the cornea must be decreased — the cornea must be made flatter. To correct farsightedness, the curvature of the central cornea must be increased, which is accomplished by removing a donut shaped ring of tissue. To correct astigmatism, the curvature must be altered in one specific direction.
With the advanced laser eye surgery technology and surgical techniques we now have, there is virtually no limit to treating single errors, or combinations of errors. For extreme refractive errors, there may be a need for a combination of both Refractive Surgery and Excimer Laser technique.
In terms of age, patients must be at least 18 years old, and have stable vision. For people over 18, there is no age limit for laser treatment. Women of child-bearing age must not be pregnant or breast-feeding at the time of the operation. Please read FAQ: Are you a good candidate for Laser Eye Surgery?
We have corrected with Refractive Eye Surgery up to 27 dioptres with Myopia (the average is 2-5), 14 dioptres with Astigmatism (average 1-3), and 16 dioptres with Hypermetropia (average 1-4).
So, on average, we operate safely within an extremely wide variation.
(Note: A dioptre is a unit of measurement of the degree of refractive error. In other words, the degree to which the eye distorts an image.)
