Can You Get Lasik Eye Surgery In Just One Eye?

We have had many patients come to us who are very excited about LASIK and are excited that the surgery is being done on both eyes and look forward to seeing more clearly. For some patients, it’s not so simple.Patients often ask whether it is safe to have LASIK on both eyes simultaneously or whether one eye should be operated on first and then the other again later.

It seems logical to want to see good results with one eye before moving on to the other. Patients assume it is safer to treat one eye at a time, but on the surface, it appears to be a more conservative method.


Are there any cases in which only one eye surgery is done? 

Some patients are nearsighted, farsighted, or astigmatic in only one eye. Of course, if one eye is normal and the other looks blurry, treat only the eye that needs it.

It is one of the many reasons why scheduling your first LASIK consultation is so important. Some eyecare centres do not perform LASIK on patients without a thorough eye exam to ensure they are good candidates for LASIK.


What about Monovision LASIK? Do you mean to treat only one eye?

Sometimes Monovision means that LASIK has good near vision in one eye and good distance vision in the other. Usually, you identify your dominant eye and prepare to try contact lenses with distance vision in your dominant eye and near vision in your non-dominant eye.

If the patient is satisfied with the visual acuity achieved in this ‘experiment,’ suggest LASIK to achieve the same results.



Monovision is a clinical technique used to correct presbyopia, the gradual loss of the eye’s ability to change focus in close-up pictures that progresses with age. The purpose of monovision is for presbyopic patients to use one eye for distance vision and one eye for near vision. This method is used for fitting contact lens wearers and, more recently, for LASIK and other refractive surgeries. With contact lenses, presbyopic patients wear a contact lens in one eye to correct distance vision and a contact lens in the other to correct near vision. Similarly, in LASIK, a presbyopic patient has surgery on one eye to correct distance vision and the other eye to correct near vision.

As one eye is corrected for distance vision and the other for near vision, the eyes become uncoordinated. It reduces vision and reduces depth perception. These effects of monovision are most pronounced when performing tasks that require low light or very sharp vision. Therefore, when performing visually demanding tasks, such as long printing sessions, it may be necessary to wear glasses or contact lenses for full binocular correction.

Many patients cannot get used to the fact that one eye is always blurred. Find out if you can meet the driver’s license requirements.

We also need to consider how presbyopia may increase in the future. Unsatisfactory results from monovision surgery, expected to be unable to see near objects clearly without glasses or contact lenses or need a second surgery to further correct near vision. If you do, consult your doctor.


Bilateral Treatment:

You can choose to have LASIK surgery done on both eyes simultaneously or on one eye simultaneously. The convenience of having both eyes operated on the same day is attractive, but the risks are higher than two separate surgeries. If you treat one eye at a time, you and your doctor will decide how long it will take to operate. Another disadvantage of having both eyes operated on simultaneously is that after surgery, vision in both eyes may be blurred until the initial healing process is complete.


Why Get LASIK in One Eye?

In most cases, LASIK is done on both eyes simultaneously. However, there may be times when LASIK is in one eye, or the patient wants to treat each eye on separate days.


Vision Problems Affecting Only One Eye

LASIK can occur in only one eye mainly because of a refractive error, especially anisometropia (lazy eye). Refractive errors can occur in several eye conditions with LASIK surgery. You may be nearsighted or farsighted and have astigmatism in only one eye. Another visual impairment is presbyopia.


Patient Requests

Occasionally, patients want to get LASIK in one eye at a time, usually choosing to have surgery on the “bad” eye. The reason is that they want to see the effect of LASIK before treating the other eye. Some even believe that this is a safe method.

Bad eyesight is a widespread problem that every adult, including small children, faces. It can be a congenital disability or can happen if you put too much strain on your eyes. Typical eye problems are myopia (nearsightedness) and hypermetropia (farsightedness). In addition to this, older people can also have presbyopia or astigmatism. But carrying and wearing them every day can be a bit cumbersome. Thanks to modern medicine, we have a lot of permanent alternatives available. There are a lot of eye surgeries available through which you can permanently get rid of spectacles and get 20/20 vision. The surgeries differ in how they are performed; some involve reshaping the cornea, and others include implanting artificial lenses.
