Monovision LASIK & Presbyopia
Are you starting to notice difficulty reading clearly? Do you find that you have to adjust your focus to achieve simple things like reading a menu? At around age 40, most people develop a condition known as Presbyopia that causes the eye to lose focus at close distances. For people with Presbyopia, objects that are at close distances are hardest to see clearly.
Presbyopia often begins in patients during their early 40s or 50s and increases until reading glasses or bifocals are required. Monovision LASIK was developed to correct presbyopia in patients by leaving their non-dominant eye slightly nearsighted. This allows the stronger eye to take over. This procedure is called Monovision LASIK and may be performed in a variety of ways, each personally customized, depending on each patient’s individual circumstances.
Monovision Can Be Challenging For Some Patients
Only 75 percent of the population can adjust to Monovision, though some patients cannot because it can decrease depth perception, impair night vision and make driving slightly more difficult. If you are interested in Monovision LASIK, during your free consultation you will undergo a typical LASIK evaluation, during which Dr. Green will evaluate your risk factors and determine what type of surgery would be most suitable for you.
In addition to undergoing the usual tests, patients interested in Monovision LASIK should test the effects of Monovision through the use of contact lenses that produce the Monovision effect. Also, you must take into consideration your occupation and lifestyle. For instance, people who operate heavy machinery, those who require acute night vision, such as pilots or truck drivers, or patients who perform sports and outdoor activities that require precise depth perception might choose to bypass Monovision LASIK.
Monovision LASIK surgery is similar to other LASIK surgery as far as the procedure. We recommend that you have a friend or family member on hand to drive you home after surgery, as you will still be affected by the effects of medication and will be unable to operate a vehicle by yourself.
The only difference between regular LASIK and Monovision LASIK is that Dr. Green must focus closely on the dominant eye. After surgery, patients must remain in close contact with Dr. Green, especially if side effects do occur. A majority of patients who test Monovision with contact lenses and adhere to Dr. Green’s recommendation do heal and adjust to their new vision perfectly.
Is Monovision LASIK Right for You?
The natural lens inside your eye is an amazing structure because it changes shape as you focus on objects near and far. When you look at things that are near, your lens fattens and when you gaze into the distance, the lens becomes thinner.
This system functions optimally until around age 40 or shortly thereafter when your lens gradually begins to lose its ability to focus, resulting in blurred vision when focusing on close objects. You may need reading glasses or need to switch to bifocals so you can see both near and far with one set of glasses. You may also notice a slight delay in changing focus from near to far. This condition is known as presbyopia and is the most predictable change in the human body.
Monovision contact lenses have been used for years and the concept is readily adaptable to Laser Vision Correction. With this system, your dominant eye is corrected for distance and the non-dominant eye is slightly under or over corrected (depending on whether you are nearsighted or farsighted to begin with), which means its primary focus is on nearby objects. Both eyes are still working constantly, but your brain soon learns which image to select. This system can reduce or eliminate the need for reading glasses for people with presbyopia.
For some patients, it may take several weeks to adjust to Monovision LASIK. During this adjustment period, your vision may seem less sharp as your brain learns to select and emphasize the clearer image. For many people, this is most noticeable while driving at night and may impair night vision. The length of the adjustment period depends on the individual, but people adapt much more quickly if they take their mind off the idea of Monovision and avoid comparing the vision in each eye.
Monovision will reduce the need for glasses in people with presbyopia by providing focus at near and far distances; however, Monovision LASIK does not guarantee that you will never need to wear glasses again. Some patients may still require glasses for certain activities, such as night driving and/or reading extremely fine print. People who rely on heavy use of distance vision, such as those who work outdoors, may opt to have both eyes corrected for distance and simply wear glasses for occasional close work.
We offer Monovision LASIK to people with presbyopia as a flexible, practical solution to reduce your dependency on corrective lenses. Most people who choose Monovision LASIK are happy with the results.
Monovision is a personal decision that must be made by each patient after careful assessment of his or her lifestyle. Ask yourself the following questions to help you decide if monovision is right for you:
- What percentage of my time do I spend focusing on nearby objects versus objects at a distance? Take into consideration your occupation, activities, hobbies, crafts and such habits as applying cosmetics, shaving or extensive reading or drawing.
- Do I work in an indoor environment or do I spend considerable amounts of time working on a computer or reading? Does my lifestyle require sharp long-distance focus for activities, such as flying a plane, driving or playing sports?
- Am I generally easily adaptable? With Monovision, one of your eyes will be slightly under or over corrected for vision at close range. However, Monovision LASIK works because your eyes normally work together. Those people who regularly compare the vision in each eye separately will not adapt well to monovision.
- Am I a perfectionist or am I somewhat flexible? Monovision is not a perfect correction, yet it may be a perfect choice for those willing to compromise a small amount of distance vision to gain the ability to see things up close without the use of reading glasses.
- Is my distance vision more important to me than my close vision? Is it critical to me to have the best possible distance vision? With Monovision LASIK, you may sacrifice a small percentage of distance vision to gain improved up-close vision without correction.
