LASIK in Boston, MA

What is LASIK eye surgery?

Laser vision correction has revolutionized the field of ophthalmology, and LASIK is the most popular technique available. LASIK, or laser in-situ keratomileusis, has been helping individuals see more clearly for many years, enabling them to enhance their day-to-day lives and reduce the hassles associated with corrective eyewear.

What happens during LASIK?

During LASIK, you will receive numbing eye drops. There is no pain during LASIK, and the most you’ll feel is a slight pressure. LASIK involves reshaping the cornea so light can get through properly. Reshaping the cornea is what corrects refractive errors like nearsightedness, farsightedness, and astigmatism. To reshape the cornea, a small flap, like a trap door, is first created with a femtosecond laser.

After the flap is created, your surgeon will remove tissue from the cornea with an excimer laser. Once the cornea is reshaped, the flap is gently placed back down and left to heal on its own. There are no stitches required. LASIK takes about 10 minutes total to complete and involves no needles, shots, or blades.

Who is a good candidate for LASIK?

To find out if you’re a good candidate for LASIK, you’ll need to schedule a LASIK consultation. Here are some of the factors that go into whether you’re a good candidate:

  • you are in good health
  • you must be at least 18 years old to undergo LASIK
  • you cannot be pregnant or nursing when getting LASIK
  • your corneas are thick enough that LASIK is safe to perform on you
  • you must have a stable prescription that hasn’t changed in the last year or more
  • you don’t have any conditions that make it harder to heal after a procedure like LASIK
  • if you have dry eye, it is already being managed and is not causing injury to your eyes
  • you don’t have any conditions like dry eye that aren’t under control before your procedure

These are only a few of the factors taken into consideration, which is why anyone interested in LASIK must schedule a LASIK consultation. During your LASIK consultation, it is important to disclose your entire medical history.

Why LASIK at Nielsen Eye Center?

  • Speed: The Allegretto Wavelight laser is the fastest laser available in the world. Treatments are completed in less than 15 seconds per eye! Decreased treatment time promotes faster visual recovery, increases predictability and reduces the incidence of complications.
  • Optimization: Every treatment is customized to the individual’s prescription and cornea. On an older laser, all patients with the same
    prescription would get the same treatment. On the Allegretto laser, we make a map of your individual eye (your personal and unique nomogram created by your surgeon) and perform a custom treatment.
  • Precision: Eye-tracking technology ensures that the laser is lined up correctly with every pulse that hits your eye. It tracks the eye’s movement 400 times per second! It also uses a smaller spot size that allows the laser to treat the exact spots on the cornea that needs treatment.

How can I Prepare Before LASIK?

There are several best practices that help to ensure that the LASIK procedure goes as smoothly as possible, which your eye doctor will discuss with you prior to your surgery. If you wear contacts, your surgeon at Nielsen Eye Center will tell you when to stop wearing them for a period of time. Wearing contacts can temporarily change the shape of your cornea.

Another way to prepare is by drinking more water. Dry eye is a common side effect after LASIK, so being well-hydrated can make a big difference in ensuring your eyes are lubricated and healthy! You should also make sure to find a family member or friend who can drive you to and from your procedure. During LASIK, your eyes will be numb thanks to numbing eye drops. It is not safe to drive yourself home after LASIK, so find someone who will stay with you during your procedure.

What is LASIK recovery like?

Like any surgical procedure, there is a recovery process after LASIK eye surgery. In the first day or two after LASIK, it’s normal for your eyes to feel dry. This is temporary and goes away over time. Your eye doctor will prescribe eye drops to prevent infection and inflammation. It’s important to take these exactly as directed! If your eyes feel dry, you can use artificial tears. Whatever you do, avoid rubbing your eyes at all costs. Rubbing your eyes can lead to damaging the fragile flap created during LASIK.

At your follow up appointment the next day, your doctor will check to see if your eyes are healing properly. If your eyes look good, you’ll also be able to drive again. You should avoid any strenuous exercise for the first week after LASIK. For the first month, don’t go into any hot tubs, pools, or the ocean. You should be especially careful around bodies of water, and cautious even while showering. Water is a perfect place for bacteria to grow and cause an infection!

LASIK Step-by-Step

LASIK utilizes state-of-the-art laser technology to reshape the eye’s cornea and to allow for improved refraction of light. This can correct a number of refractive errors and help patients attain substantially clearer vision. The LASIK procedure is a quick outpatient treatment, and most patients begin experiencing clearer vision by the next day.


LASIK technology has continued to advance over the years, and our doctors are committed to providing our patients with the most precise LASIK techniques. Technology at our practice includes the Wavefront-Guided LASIK with Allegretto Wave® system, IntraLase™ all-laser LASIK treatment, and Flapless LASIK (PRK) for patients who may not be candidates for the standard LASIK procedure.


Monovision LASIK is a treatment that can help patients suffering from presbyopia – farsightedness caused by the loss of elasticity of the lens of the eye. Presbyopia usually affects individuals over the age of 40. This treatment is ideal for presbyopic patients who would like to reduce their dependence on bifocals in order to clearly see objects at near or far distances.

 Are You a Candidate?

If you are looking for an effective way to correct visual refractive errors and diminish your dependence on eyewear, you may be a candidate for LASIK. During your initial LASIK consultation, our doctor will evaluate the condition of your eyes and determine if this procedure is best for your needs.
