Lasik Results & 20/20 Vision

LASIK Candidate


Do most people have perfect (20/20) vision after laser vision correction surgery?

Although there is no guarantee, most NVISION patients who receive laser vision correction surgery attain 20/20 vision or close to it.  Typically, NVISION patients receive the very best corrected vision they have when wearing glasses or contacts, only they now have it without the need for glasses or contacts.  At NVISION, our doctors care about restoring their patients’ most precious sense:  their sight.

What does 20/20 mean?

In the most common visual clarity test, an optometrist places an eye chart at a standard distance of 20 feet.  At this distance, the letters on the chart representing normal clarity on the eye chart are designated “20/20,” the smallest line that a person with normal clarity can read at a distance of 20 feet.  It is possible to see better than normal clarity, which optometrists designate at 20/15 or 20/10.  In laser surgery, it is the doctor’s goal to help your vision without glasses to be at least as good as it was with glasses before surgery.

What can laser vision correction do for me?

Laser vision correction has proven to be successful in reducing dependence on glasses and contact lenses and in improving clarity of one’s vision.  However, the degree of improvement may vary among individuals depending on the severity of the patient’s prescription and how quickly he or she heals.  Although no doctor can promise “perfect 20/20 vision,” most laser patients with mild to moderate prescriptions do achieve 20/20 vision or very close to it.  This means they no longer need glasses or contacts to drive, play sports, watch TV, or participate in careers that require excellent vision.

Will laser vision correction improve my night vision?

Many patients who have had custom LASIK report that their night vision is improved.  Because custom LASIK corrects the unique imperfections in each person’s vision, it also improves the overall clarity, especially at night.  At your pre-procedure consultation, your doctor will explain the range of your probable outcome based on your particular prescription, healing profile and expectations.  Research is collected from NVISION’s hundreds of thousands of procedures and shared across the NVISION network, helping our doctors to best ascertain what results are most likely for each patient, before surgery is ever done.

Can laser eye procedures treat amblyopia (lazy eye)?

Laser eye surgery cannot specifically treat a lazy eye; however, suitability for laser vision correction surgery with the goal of improving overall vision will depend on the best corrected visual clarity (with glasses or contacts) of the lazy eye.  Many patients with lazy eyes have successful outcomes after laser surgery.

Can laser eye procedures treat strabismus (eye turn)?

Laser eye surgery cannot specifically treat a strabismus problem (eye turn); however, suitability for laser vision correction surgery with the goal of improving overall vision will depend on the best corrected visual clarity (with glasses or contacts). Many patients with strabismus have successful outcomes after laser surgery.  However, if strabismus (eye turn) is due to amblyopia (lazy eye), laser surgery will not be able to restore vision beyond that which is attainable with glasses/contacts.

How long do the benefits of the laser vision correction surgery last?

The benefits of laser vision correction surgery can last a lifetime, depending on the patient’s condition and treatment. The NVISION for Life®® is NVISION’s promise that if an enhancement is needed to maintain vision results, clinically qualified participating patients will receive a same-technology enhancement procedure without charge at any NVISION Laser Eye Centers location across North America.

How is LASIK success measured?

Many patients who have had custom LASIK have reported being able to see more clearly than ever before because custom LASIK can improve not only what you see but how clearly you see it.  In the past, vision was measured using a standard vision chart.  With custom LASIK, doctors can focus on more than the standard vision number and are able to ascertain the quantity (a number, such as 20/20) and quality (clarity) of your vision.

What conditions are unsuitable for  LASIK?

There are certain corneal dystrophies or conditions that may not be suitable for LASIK.  NVISION offers alternative refractive surgery options for those individuals deemed as non-candidates for LASIK at their pre-procedure consultations.
