LASIK

LASIK

What is LASIK?

LASIK (Laser-Assisted In Situ Keratomileusis) is one of the most popular and well-known procedures for correcting myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. During this blade-free procedure, a laser gently reshapes the cornea – the clear window in front of the eye – to improve your vision and reduce your dependence on glasses and contacts. 

Am I A Candidate For LASIK?

In order to qualify for LASIK, patients must meet the following basic requirements:

  • 18 years of age or older
  • Nearsightedness, farsightedness or astigmatism which falls within range of effective treatment
  • Stable vision for at least 1 year
  • No eye health issues
  • No general health issues that can affect the eyes

If you meet the above guidelines, we invite you to come to our office for an evaluation with Dr. Nightingale to determine if you are a strong candidate for LASIK. 

Myopia (nearsightedness)

When the eye is too long or the cornea is too steep, light entering the eye cannot be focused correctly (focuses before the retina) which causes distant objects to appear blurry.

Hyperopia (farsightedness)

When the eye is too short, light entering the eye cannot be focused on the retina (focuses past the retina) which causes intermediate and near objects to appear blurry.

Astigmatism

When the cornea is irregularly shaped, light entering the eye cannot be focused sharply on the retina which causes blurred vision at all distances.

LASIK Evaluation

Dr. Nightingale and our staff will conduct a detailed analysis of your vision and eye health to determine if you are a strong candidate for LASIK. The evaluation will include the following:

  • Detailed measurement of your prescription and refractive error by the surgeon
  • Mapping of your corneal shape (cornea topography)
  • Corneal thickness measurement (corneal pachymetry)
  • Dry eye evaluation
  • Pupil size
  • Overall eye health review
  • Dilation of pupil for detailed evaluation of overall eye health
  • Custom LASIK measurement for patient-specific LASIK treatments 

After consideration of this extensive evaluation, Dr. Nightingale will be able to determine if you are a strong candidate for LASIK. In the event you are not a strong candidate for LASIK, Dr. Nightingale can determine whether you are a suitable candidate for other vision correction procedures like PRK or Refractive Lens Exchange. Vision correction surgery is not suitable for many patients and Dr. Nightingale will also inform you if you are not a good candidate for any vision correction procedure. 

How Do We Perform LASIK?

On the day of your LASIK procedure, your eyes will be numbed with anesthetic eye drops and you will be given a sedative medication (Valium) to help you relax. Dr. Nightingale will review the LASIK treatment plan with you.

LASIK involves two steps:

  1. Creation of a corneal flap. The flap will be created safely utilizing the Intralase femtosecond laser in a matter of seconds. We only perform advanced blade-free, all laser LASIK for corneal flap creation, which has reduced complications compared to the older microkeratome blade.
  2. Reshaping the cornea to correct your vision. We use the VISX Star S4 IR Active Trak excimer laser to safely and accurately reshape your cornea to treat your nearsightedness, farsightedness and/or astigmatism.

After the reshaping of your cornea is complete, the corneal flap is gently returned to its original position where it self-seals. You will be brought to a room to relax and Dr. Nightingale will review some post-operative instructions with you.

Custom LASIK vs. Conventional LASIK

What’s the difference?

Conventional LASIK involves using the standard method of measuring a patient’s glasses prescription as the input to the laser. Dr. Nightingale carefully determines your optimal glasses during your LASIK evaluation visit in order to determine the best LASIK correction.

Custom LASIK uses a special measurement device and computer to create a map of all the subtle imperfections of a patient’s vision. This is called a “Wavefront Map” and it is unique to each patient, much like a fingerprint. Custom LASIK utilizes these highly precise measurements, in addition to a patient’s glasses prescription, in order to form a patient-specific treatment profile. Dr. Nightingale prefers custom treatment to conventional. We utilize the iDesign suite and Star S4 excimer laser by Johnson & Johnson for our treatments.

Frequently Asked Questions for LASIK

This 20-30 minute procedure is painless. Anesthetic eye drops are used to numb your eyes. We normally give you a relaxing medication prior to the procedure to reduce any anxiety you may have during the treatment. After LASIK you can experience a few hours of light sensitivity, burning and tearing which are temporary and typically last around 4 hours and begin to subside.

Immediately after LASIK, you will notice that you no longer need glasses to see in the distance. The vision is blurry on the day of LASIK. Most patients find their eyes and vision feel fairly normal within 24-48 hours. However, the eyes continue to heal from LASIK over the course of 3 months so there is subtle improvement throughout that time. It is normal to have mildly dry eyes in the first few weeks or months after LASIK.

Most patients find that they can return to work the day following LASIK.

We ask that patients refrain from swimming, hot tubs, saunas and steam rooms for one week after LASIK. Light exercise is permitted the day following LASIK, but we ask you to refrain from vigorous exercise for one week.

In the event you are not a candidate for LASIK, Dr. Nightingale will inform you and evaluate you for other refractive procedures. These other procedures include:

  • Photorefractive Keratectomy (PRK)
  • Refractive Lens Exchange (RLE)
  • Implantable Collamer Lens (EVO ICL)
