LASIK FAQS

Why LASIK?

LASIK, or Laser in-situ keratomileusis, and PRK, or Photorefractive Keratectomy, are non-invasive laser procedures that change the shape of your cornea to correct your vision to enable you not need glasses or contacts any more for vision correction.

What Is LASIK?

When light rays travel through your eye- they go through the clear cornea, lens and focus onto the retina and are then transmitted into neuro-electrical signals which are then sent to the brain. If you are nearsighted or “myopic,” your cornea is too steep and/or your eyeball is too long, and the light rays focus in front of the retina. If you are farsighted, or “hyperopic,” your cornea is too flat and/or your eyeball is too short and the light rays focus behind the retina. The goal of LASIK (and PRK) is to resurface the front of the cornea to make it flatter in the case of myopia, and steeper in the case of hyperopia, to enable the light rays to focus perfectly onto the retina and for you to see without glasses or contacts correction.
In LASIK, or Laser in-situ keratomileusis, a flap is created by a laser, the flap is then lifted, the laser resurfaces the corneal layer underneath, and the flap is put back down. The top layer, or epithelium is not removed during this procedure, and thus there is no discomfort in the few days after the procedure.

Am I a qualified candidate for LASIK?

There are certain criteria that you are required to meet in order to qualify for LASIK:
  • Over age 18, preferably older than 21 so that your prescription is stable
  • Stable prescription for over a year
  • A glasses/ contacts prescription that can be corrected by LASIK- the correctable prescription by LASIK is a narrower window than with PRK
  • Healthy corneas
  • Healthy eyes
  • You can have regular astigmatism, but not irregular astigmatism- irregular astigmatism can signify other issues (see blog post: https://www.manhattaneyenyc.com/what-is-astigmatism-what-is-regular-or-irregular-astigmatism/)
  • Your corneas need to be healthy and your overall eye health must be good.
There are also certain characteristics that disqualify you for LASIK/PRK:
  • A prescription that is changing and not stable
  • A prescription that is above the parameters for LASIK
  • History of overactive scarring
  • Certain dermatologic diseases that can affect healing
  • Uncontrolled dry eye or blepharitis
  • Corneas that are too thin
  • A history of recurrent corneal scratches
  • Eye diseases such as glaucoma, macular degeneration, retinal or corneal scarring
  • Visually significant cataract
  • Diabetes mellitus that is poorly controlled
  • Pregnant or nursing women
  • Keratoconus (cone-shaped cornea) (see blog post: https://www.manhattaneyenyc.com/what-is-keratoconus-and-how-can-i-treat-it-what-is-collagen-cross-linking/)
  • Family history of a corneal transplant/corneal disease

What Should I know Before My Evaluation?

If you are interested in finding out if you are a candidate for LASIK, or Laser-Assisted In Situ Keratomileusis, you need to come in for a full evaluation. You will need to remain out of your contact lenses for a specific amount of time before the evaluation. If you have a soft contact lens prescription with only a spherical correction (no astigmatism), you need to be out of your contacts for 10 days prior. If you wear soft lenses with astigmatic correction, you need to be out of your contacts for 21 days prior. If you wear rigid gas permeable lenses, you need to be out of the lenses for a week for each decade of contact lens wear. For example, if you wore rigid gas permeable lenses for 25 years, you need to not wear them for 2.5 week prior to the measurements.
It is important to remain out of contacts so that your cornea returns to its original shape and thus the measurements and calculations are accurate.
During the evaluation with Dr. Rapoport in the office, your prescription will be checked multiple times. Your current glasses will be measured, the manifest refraction (your best correction), and the cycloplegic refraction (the refraction after your eyes are dilated). The corneal curvature will be checked several ways. A Pentacam, a type of topographer, will image your cornea to check for any irregularities that would exclude you from the procedure. Regular astigmatism is allowed, but irregular astigmatism is not. Your medical and ocular history will be thoroughly discussed. A history of certain medical conditions, such as untreated diabetes, autoimmune diseases, will prevent you from being a candidate. Certain findings on the exam, such as corneal or retinal scars, corneal dystrophies, history of certain types of infections, will also preclude you from being a candidate. A family history will also be obtained, with particular care looking at history of keratoconus or corneal transplants. If you have any ocular surface disease (blepharitis/ meibomian gland dysfunction or dry eye) that will have to be optimized and your evaluation/ measurements rechecked before proceeding with the procedure.

What Should I Expect During LASIK Surgery?

Both LASIK and PRK are performed at a laser center.
You will be offered an oral relaxing medication to take ahead if time if you choose.
No systemic anesthesia is required.
You will start antibiotic drops 2 days prior to the procedure.
If you choose, you will take the oral relaxing medication 1 hour prior the procedure, and bring the other medication with you if you choose to take a 2nd dose.
Numbing drops, along with antibiotic and steroid drops, will be placed in your eye.
A suction ring is applied to the eye, and the Intralase laser is then docked and creates a 100-110 micron thick flap.
During this time you may feel a little pressure.
The flap is then lifted under the microscope, and the excimer laser then changes the shape of the cornea underneath the flap.
The excimer laser is preprogrammed with the specific measurements of your eye.
The flap is then placed back to its original position and the edges are smoothed into position.
The same procedure is then performed on the other eye. The flap will attach on its on within a few minutes, but it is very important that you do not rub your eyes the first few days after the procedure, and especially the first night.
A see-through shield is placed over the eye, which you sleep with for a few days.
The day of the procedure, you should plan to go home and take a nap or relax after the surgery and not use your eyes to read, use your phone or watch TV.
It is safe to resume normal activities of Daily Living the following day.
Exercise is limited the first week and contact sports and swimming are limited for a month.
Your eyes may feel scratchy or like they are burning for a couple of days.
