Monovision is an optical relief methodology used to relieve patients of presbyopia symptoms. LASIK eye surgeons ensure that one eye of the patient is able to focus at a distance and the other eye is able to focus on near objects.
How does this treatment methodology work?
This treatment is based on the zoom function of the eye. The eye is able to accommodate objects in its focus at a distance when the virtue accommodation in the eye is fully relaxed. But the accommodative power of the eye increases in order to focus on near objects. The eyes are able to zoom in on the near object thus allowing the subject to get clarity.
The eyes accommodative power is at its best during childhood. As a person grows older, they lose this accommodative power. In their mid-forties and early fifties, eyes start losing this accommodative zoom power. After some time they are not able to see near objects clearly even if they are at arm’s length.
This accommodative power loss is called presbyopia. Presbyopia doesn’t happen to everyone in their forties or fifties. A person’s lifestyle and genetics determine their eyesight quality. Presbyopia makes it difficult to view small objects clearly. Individuals who have presbyopia increasingly rely on reading glasses that artificially stimulate this accommodative power of the eyes. A person with presbyopia loses their accommodative power in their eyes completely by age 70.
How monovision can help
Monovision is an optical correction method that helps a person overcome this problem. Laser eye surgery enables one eye to focus at a distance and one eye to focus on objects nearby. This process requires some time for the eyes to adapt, but the patient will eventually adapt to the difference in focuses in their eyes. The brain begins to assimilate this difference and is able to switch views based on context.
The patient may require reading glasses from some time even after monovision surgery, but after a while, the patient can completely relieve themselves of their dependency on reading glasses.
How is monovision implemented?
Monovision is achieved with contact lenses. Glasses may even be prescribed in certain situations, but it is avoided given that the differential thickness in the glasses can be bothersome for the person when looking through the edges of the glass. Monovision is achieved through a surgical procedure as well. Excimer laser refractive surgery (such as LASIK or PRK) is used for this purpose. Even Conductive Keratoplasty (CK) is used based on the surgeon’s discretion. During a cataract surgery, eye doctors implement monovision by implanting an IOL in both eyes for near and distant focus.
Considerations
An eye surgeon at Sugarland Eye & Laser Center in Houston would be able to provide more information on this. Generally, most patients adapt well to monovision. Some patients could experience stereovision loss, but it is generally inconsequential. Therefore, it is fair to say that monovision is a safe treatment option with assured results if done at a premier eye clinic such as Sugarland Eye & Laser Center.
