LASIK Surgery


Laser assisted in situ keratomileusis, commonly referred to as LASIK, is a corrective alternative to glasses or contact lenses. Like glasses or contact lenses, LASIK is a method for treating refractive conditions including nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. At Sumner Vision, Dr. Sumner provides pre- and post-operative exams for LASIK and other eye surgeries. Call 303-321-1606 today to schedule an examination to see whether you are a candidate. We work with several premium professional refractive surgery centers in the Denver area.

Evaluation and Referral

LASIK (laser assisted in situ keratomileusis) surgery uses the latest advancements in technology to provide faster recovery times and precise results. LASIK surgery has been effective in treating myopia, hyperopia, astigmatism and other eye conditions. At Sumner Vision, we provide evaluations and referrals for patients interested in LASIK surgery. Dr. Sumner performs a complete review of your patient history as well as a full assessment of your eye health and vision. A current exam is important to determining if you are a candidate for LASIK surgery and if there are any other factors that may affect your results. The history review enables our optometrist to determine if your prescription is stable and you are healthy enough to consider surgery.

Once Dr. Sumner has performed the evaluation and determined whether you are a candidate for LASIK, you will be given a referral to the LASIK surgery center we have worked with on an ongoing basis. The center will perform advanced diagnostic testing and will evaluate your eligibility for surgery. Various surgery options will be discussed with you if you are determined to be a surgical candidate. We will be in correspondence with the center regarding your evaluation and surgical determination. If you are considering LASIK surgery, call us at 303-321-1606 to schedule a consultation.

Post-Operative Care

Once your surgery is scheduled, we will schedule follow-up appointments for you in our Denver office. Typically, you will begin these follow-ups the day after the surgery and continue at prearranged times over the following six months. After 1 year, a full exam is recommended to determine the long-term results of your procedure. Dr. Sumner is experienced in working with patients pre- and post-operation and will answer any questions that you have along the way. If you have questions about LASIK surgery, call 303-321-1606 to speak with our knowledgeable staff.

Advantages of LASIK

If you have worn glasses or contact lenses for a long time, you may have wondered if LASIK surgery is a good choice for you. While not everyone is a candidate for LASIK, it does have some great advantages. People who play sports, have allergies, or who are looking for simplicity will all benefit from LASIK.

High Order Aberrations Hoa Related To Lasik

High order aberrations (HOA) refer to complex imperfections of the optical system and are normally present in all eyes in minor unnoticeable amounts. However, as a result of optical refractive surgeries such as Lasik, unnatural and irregular shape of the cornea can result in increases in HOA and thus result in halos double vision, smears, and other visual disturbances. Improvement in lasers over the years has resulted in reducing HOAs but they are still present in some degree.

Measuring and Diagnosing High Order Aberrations
High order aberrations are measured with a wavefront aberrometer. We use the Izon Aberrometer to measure the distortions of light as they pass through the patient’s cornea.

Wavefront aberrometry helps in diagnosing both lower order and higher order vision errors based on how the light passing through the eye focuses or refracts.

These are some of the HOAs measured with our Izon Aberrometer.

High Order vs. Low Order Aberrations
Lower order aberrations are common vision errors like nearsightedness(myopia), farsightedness (hyperopia), and astigmatism.

High order aberrations are coma, spherical aberration, and trefoil. These aberrations result in visual disturbances like glare, halos, starbursts, blurring, double vision, etc.
