Lasik monovision pros and cons

Nearsightedness and farsightedness are possible in people over the age of 40. When evaluating vision correction alternatives, you’ll need to keep both of these factors in mind. Patients who have trouble seeing both up close and far away may benefit from monovision LASIK surgery. Continue reading to find out about the procedure’s pros and cons.

What is LASIK Monovision?

Monovision LASIK, often known as “blended vision,” is a procedure that corrects presbyopia, or the inability to see up close. One eye is corrected for distant vision, while the other is corrected for near vision. Standard LASIK corrects both eyes to see far. Monovision LASIK corrects only one eye.

When you become reliant on readers, eyeglasses, and other vision-aid devices, it can become aggravating. If you lose them in some way, your capacity to interact with the rest of the world will suffer significantly. How many times have they vanished right in front of you on the counter, on your head, or in strange places?

Patients with presbyopia benefit from monovision LASIK because having one eye see at a distance helps when the other naturally reverts to being a little nearsighted. As with any medical procedure, there are some unique benefits and drawbacks that you should discuss with your doctor before determining whether or not this is the best option for you.

Lasik monovision pros and cons

How does monovision treatment work?

Many of us have dealt with the consequences of presbyopia by wearing a cheap pair of magnified readers (often known as “cheaters”). If you’re anything like me, you have a collection of them strewn about your home and car.

Monovision—and specifically, monovision contact lenses—is a less well-known but potentially more effective approach of correcting your vision to combat the effects of aging eyes.

Monovision contact lenses operate by putting a different lens in each eye. One contact lens is for seeing and focusing on distant objects, while the other is for seeing and focusing on objects up close.

Most of us have a dominant and non-dominant eye (the dominant eye is the one you prefer to use when gazing at something with one eye closed, if you’re not sure). You wear a lens on your non-dominant eye to correct near vision and, if necessary, a lens on your dominant eye to correct distance vision with monovision contact lenses.

Monovision contact lenses, also known as blended vision lenses, function by deceiving your brain into thinking the contact lenses are part of your normal vision. This forces your eyes to work together to improve your vision in both close and vast distances. Surprisingly, while this technique works effectively with contact lenses, it has not been proven to function with eyeglasses.

While monovision contacts may seem contradictory, most people find that their eyes respond well to them, and their entire vision improves as a result. While it may take a week or so for the eyes to acclimatize to wearing two different strength contact lenses, research from The Physiological Society shows that people who use monovision contacts report significant improvements in their overall vision. Most people are unable to distinguish between which eye is used for distance and which is utilized for up-close items.

List of the Pros of Monovision LASIK

  1. It is a quick and painless process.

For certain people, monovision LASIK is an outpatient treatment that might take less than 30 minutes. The majority of your time dealing with the operation is spent getting ready for the surgery. You will be awake throughout the procedure, though some patients may benefit from a Valium to help them rest while the laser is entering their eyeball. The laser cuts off whenever the eye makes any sudden movements for any reason, to prevent harm or an error in the correction process.

All LASIK surgeries have a very low complication rate of less than 1%. Over 96% of patients who pick this choice for any reason are happy with the results. Because of the difficulties in adjusting to having one eye with vision and the other without, monovision has a lower overall satisfaction rating. This benefit has been confirmed by over 7,000 peer-reviewed published studies.

  1. When monovision LASIK is used, the outcomes are fairly quick.

It does not take long for a patient to regain or attain clear vision for the first time. Within a few hours of the procedure, the majority of patients will notice a difference. By the next day, you’ll be seeing better than you’ve ever seen before. It takes the average person around 48 hours to resume their normal daily activities. Then you can appreciate the clarity of the colors and their vibrant colours in ways that are as good as, if not better than, what you’ve seen before.

If the surface of the cornea was remodded in some cases where LASIK-like surgery was utilized instead, a lengthier recovery may be required.

  1. You can place your contacts or spectacles in the drawer.

When you and your doctor agree that monovision LASIK is the best treatment for your vision problems, you can have life-changing outcomes in minutes. Patients are often able to participate in fundamental activities that were previously impossible for them due to their poor vision. The final straw is generally a trigger, such as coping with dry eyes all of the time or losing their glasses while driving or riding a bicycle and becoming trapped.


Although some individuals may need to use glasses or contacts in certain settings, the majority of people can get rid of them for permanently. After recovery, you have a 20-30% chance of achieving 20/20 vision, but it’s a good possibility.

  1. Patients do not need to make any conscious visual modifications.

When monovision LASIK is performed successfully, the dominant eye sees at a distance while the other handles close-up duties. Most people acclimate to this sort of vision in around 6-8 weeks, while some patients may take up to 12 weeks. With this treatment, you don’t need to make intentional choices to achieve better post-operative results. Even though your eyes are given separate responsibilities instead of functioning together, your brain will attempt to appropriately interpret the data so that you feel like you can see well.

  1. Medicare may reimburse the cost of the monovision LASIK treatment.

If your doctor determines that improving your eyesight is necessary to preserve or improve your quality of life, Medicare Advantage may reimburse the cost of monovision LASIK. Anyone with private health insurance would follow standard procedures for dealing with copays, deductibles, and coverage percentages.

If you don’t have health insurance, LASIK can cost anywhere from $1,500 to $3,000 if just one eye needs to be corrected.

  1. it’s possible that your contrast vision will improve.

If you choose monovision LASIK to correct your vision, you will notice a significant increase in contrast vision almost immediately. Because of this particular benefit, some people can even begin driving at night. Although you won’t be able to completely remove the eyeglasses, it can produce remarkable benefits and help some people to reclaim some independence.

List of the Cons of Monovision LASIK

  1. Some people are not candidates for LASIK surgery.

Most adults over the age of 40 are not regarded ideal candidates for LASIK monovision surgery. This disadvantage is caused by a condition known as presbyopia. It causes the lens of the eye to stiffen, which can make close-up vision difficult. Because this surgery affects the cornea rather than the lens, it won’t aid the patient’s eyesight.

A photorefractive keratectomy may be a better alternative than monovision LASIK if you have a thin cornea or a high prescription for your glasses. The treatment is similar to LASIK, but it does not require the “flap-making” that LASIK does.

  1. There are some risks that you should be aware of.

It’s fairly uncommon for someone who has monovision LASIK to experience dry eyes for up to three months after the treatment. Although the chances of this problem becoming permanent are slim, it is possible. The majority of people can manage their visual problems by utilizing artificial tears.

After your surgery, you may experience problems with halos and evening glare. The hazards are significantly reduced, and the treatment zone now encompasses the entire cornea rather than only a section of it. On a conventional eyechart test, about 0.6 percent of patients lose up to two lines of visual acuity.

  1. Monovision’s flaps are number three. Years after LASIK, the eye can be damaged.

In the classic monovision LASIK procedure, a thin, hinged flap is created in the cornea. It is raised to allow for the use of laser energy to reshape the eye. This result is achieved using a device known as a microkeratome. If you choose a practitioner who uses this technique (or if you had surgery before 2007), any harm to your eye could result in the procedure being reversed. It could be as basic as an eye poke or a scrape.

The first FDA-approved bladeless procedures, known as iLASIK, were introduced in 2007. If you want to avoid this potential disfigurement, Visumax, zLASIK, and Femtec are additional choices to explore.

  1. it’s possible that you’ll have to repeat the procedure.

This disadvantage is most likely to affect people who had a higher prescription previous to monovision LASIK surgery. Even after the treatment, a condition known as myopic reversion can cause small vision quality declines over time. The inclination to revert to the previous prescription will be less pronounced, but it will have an impact on a person’s way of life over time.

If you and your doctor determine that a second operation is necessary, you’ll have to weigh a whole new set of risks. To be happy with the results, most patients need 20/20 vision in one eye and J2 vision in their reading eye.

  1. It can only repair one eye at a time.

Patients who are qualified for monovision LASIK will only receive the correction in one eye because to the issue of presbyopia. It isn’t a perfect answer because it might cause issues with intricate close work, depth perception, and night driving, but it can help older patients who would otherwise be ineligible for the procedure. As a result, 85 percent of the time, the output is satisfactory and well-tolerated.

To discover if you can handle this unique process, talk to your doctor about trying monovision using corrective lenses first. If you can bear it for a short period of time, it could be a permanent treatment that enhances your vision.

  1. Some individuals require stronger lighting when reading.

Some people discover that their extended reading periods require stronger light levels as a result of the changes that occur following monovision LASIK. Trying to read text in low light or warm tones, such as those provided by a computer, can be uncomfortable. This disadvantage can be so bothersome that some people resort to wearing glasses to deal with it.

Some monovision LASIK surgeons even encourage wearing glasses for visually taxing occasions like a theater performance or driving at night.

  1. Monovision is not always well tolerated by patients.

Even after a trial time with monovision while wearing corrective lenses, some patients discover that having the genuine thing might be difficult in real life. Because the adjustments are difficult for doctors, they are sometimes asked to reverse or improve the outcome. Some people require up to three months to adjust to the shift in visual feedback, so there can be a lot of frustration throughout the recovery if clarity is not noticed right away.

  1. LASIK surgery is not covered by Medicare.

Any LASIK surgery is classified as an elective operation if you have original Medicare coverage. There are no benefits handed out to you even if your doctor thinks that the operation is required to improve your quality of life. If you have glaucoma or diabetes, and the procedure is medically essential as part of your treatment plan for those disorders, you may be exempt from this disadvantage.

That is why you should think about enrolling in a Medicare Advantage plan. Your Part A and Part B benefits must be covered by this policy, but many also provide extra coverage alternatives, such as routine vision care. If you’re concerned about the expense of LASIK, you should explicitly inquire about coverage.

  1. Some individuals report that their vision is hazy.

After obtaining monovision LASIK, which is identical to other surgical interventions for this type of eyesight, you can resume regular activities in about a day. During recovery, some people will have clear, bright vision, while others will have a “haze” that won’t go away completely. Consider the last foggy day you can recall and how it felt to see something from afar. Remember how the lights appeared while your vision was impaired? That description is a good match for what some people experience after undergoing this surgical procedure.

How long does monovision LASIK take to adjust to?

After 6 to 8 weeks, most patients adjust to integrated vision surgery. This is due to the fact that your brain must adjust to your new eyesight, which might take weeks or months. Patients who wore monovision contact lenses before LASIK may adapt to the procedure more quickly than others.

Why is my eyesight hazy after monovision LASIK?

Blurry vision might arise following monovision LASIK surgery. It might irritate you for a day or two, but it will go away. Blurry vision after LASIK is common and typically harmless.

Is it possible to reverse monovision LASIK?

Yes, LASIK for monovision can be reversed. If you can’t adjust to the treatment, your optometrist may suggest a near-eye improvement procedure. To conduct near jobs after the reversal, reading glasses will be required.

Is surgery for monovision a better option?

When it comes to monovision, the best approach to figure out if it’s right for you is to speak with your optometrist and try it out.

If you discover that monovision lenses restore your vision, you might want to seek monovision surgery or monovision LASIK as a more permanent treatment. Monovision LASIK produces the same corrected blended vision as monovision lenses, but without the need to wear them. Specifically, your dominant eye will be corrected for distance vision and your nondominant eye will be treated for near vision during a monovision surgical surgery.

The monovision LASIK technique, like regular LASIK, employs a laser to reshape the cornea to correct refractive abnormalities unique to your eyes. Because LASIK is an irreversible operation, it’s a good idea to talk to your doctor and try monovision contact lenses before committing to the procedure.

Conclusion on the Pros and Cons of Monovision LASIK

When you just require one eye for distance vision and the other for near vision, monovision is an option to consider. If you are above the age of 40 and have certain vision problems, this option becomes part of your treatment plan.

It’s a treatment that’s been used successfully with contact lens correction for over 20 years. LASIK allows people who are ideal candidates for this type of vision to achieve a permanent result. To achieve the most comfortable outcomes, this option allows the dominant eye to focus at a distance.
