Presby Lasik is an innovative Lasik eye correction procedure that allows patients to become less dependent on glasses and other reading aids that are the result of presbyopia. So, what exactly is presbyopia and is there such a thing as presbyopia reversal?
As we get older we lose the ability to focus at near and intermediate distances. As a result, after 40 years of age, a person’s ability to read starts to deteriorate and by the age of 50 nearly the whole population require glasses for reading and intermediate vision. This condition is called “PRESBYOPIA”. It is a normal age-related change of the eye that slowly progresses until the age of about 65. There is no medication or eye exercise to treat or prevent this condition. Bifocal, multifocal, or reading spectacles are usually prescribed to enhance intermediate and near vision. Up until recently this was the extent of presbyopia correction.
(Please note that Presby Lasik can also be used to treat patients with a wide array of refractive conditions including emmetropia, hyperopia, low myopia, and low astigmatism.)
Presby Lasik is quite similar to a standard Lasik eye correction procedure, but of course there are a few slight differences. The surgery is also known as ‘multifocal Lasik’ because the overall object of the operation is the same as that of artificial multifocal lenses.
Conventional Lasik procedures reshape the eye’s surface so it can focus better at either a near or far range, depending on whether you are farsighted or nearsighted. Sophisticated technology now enables multiple or progressive zones to be incorporated by reshaping the cornea into precise contours that alter the way light rays enter the eye to achieve focus.
Presby-Lasik corrects presbyopia in the following manner:
An excimer laser reshapes your cornea into different zones for far-, near- and intermediate vision. Your brain then selects which zone it needs to see through to get the sharpest vision, depending on whether an object is near or far away. In each zone, light is bent or refracted differently, allowing people with presbyopia to regain good vision at all distances – similar to how multifocal contact lenses correct presbyopia. Multifocal contact lenses (that rest on the surface of the eye) has the potential to move and cause visual distortions. Presby-Lasik on the other hand provides fixed, stationary zones directly on the eye’s surface.
A multifocal cornea is an attractive alternative to currently available multifocal and accommodating IOLs. Presby-LASIK is a truly promising technique that is used the world over with astounding results.
Benefits of Presby Lasik eye correction
- High level of effectiveness
- Long-term stability
- Relatively low cost
- Possibility of retreatment
- Low incidence of complications
- Low degree of optical side effects
- It can be performed at the very onset of presbyopia
Monovision is another way to treat presbyopia. Lasik can be used to fully correct your dominant eye for distance vision, while your non-dominant eye is corrected for good near vision. For many people this successfully makes them independent of spectacles for both far and near vision.
