For us to see clearly, light rays enter our eyes through the clear cornea, pupil, and lens. These light rays are focused directly onto the retina, the light-sensitive tissue lining the backs of our eyes. The retina converts light rays into impulses that are sent through the optic nerve to our brain, where they are recognized as images.

Seventy percent of the eye’s focusing power comes from the cornea and 30 percent from the lens. While problems with the cornea (the clear front window of your eye) or the lens may prevent light from focusing properly on the retina, a refractive error may prevent us from seeing clearly in certain situations, despite having a clear cornea and lens.

Today, many people are choosing to correct their refractive errors with options other than eyeglasses or contacts. Various forms of refractive surgery — such as LASIK — improve vision by permanently changing the shape of the cornea to redirect how light is focused onto the retina. In some cases, instead of reshaping the cornea, the eye’s natural lens is either replaced or enhanced by an implanted intraocular lens (IOL) that helps correct vision.

We can help you make the right decision to correct your vision and thus improve your lifestyle and quality of life.

over 40? TOss the readers!

Many people around the age of 40 develop presbyopia, a condition in which the eyes gradually lose their ability to focus up close. Presbyopia can develop in patients who are farsighted, nearsighted, have astigmatism or have never needed any correction to see clearly (emmetropia). As presbyopia progresses, patients report some or all of the following:

  • Difficulty focusing when reading
  • Eye fatigue
  • Headaches or eyestrain after doing close work
  • Having to hold reading material farther away to see
  • Needing brighter lights for certain tasks
  • Having to remove glasses to see up close (nearsighted patients)

Reading glasses, bifocals, trifocals do provide correction. For some patients mono-vision or bifocal contact lenses are an option. However without surgical intervention, presbyopic patients are dependent on correction (glasses or contacts) to be able to see up close.

For the patient who:

  • Has never needed vision correction before, this means there is the need for a form of reading glasses or learning to use contact lenses.
  • Has worn glasses to see at distance, they now will need bifocal or trifocal or progressive lenses.

Fortunately there are now refractive procedures that can be performed to manage and/or correct presbyopia!

Monovision is a treatment option in which your dominant eye is focused for distance vision and your non-dominant eye is focused for near or intermediate vision. Your brain gradually adjusts to this using the visual information received from the dominant eye depending on where your vision is focused. Many patients already use mono-vision in their current contact lens correction.

LASIK or PRK can use the monovision method to provide freedom from glasses or contact lenses.

For greater freedom, Multifocal Intraocular Lens Implants (IOL’s) can correct both eyes to see distance, intermediate, and near.

Lasik

What is LASIK?
Wavefront LASIK (enhanced)

* Soft contact lenses need to be removed 2 weeks prior to pre-op and /or wavescan appointment(s)

* RGP contact lenses need to be removed 3 weeks prior to pre-op and /or wavescan appointment(s)

LASIK PREOP INSTRUCTIONS:

1. You may eat a light meal the day of procedure, but refrain from any caffeine

2. Remove all eye make-up and earrings the day of procedure

3. Abstain from wearing perfume, cologne, aftershave, or scented body lotions. Fragrances may interfere with the laser beam

4. Wear comfortable, loose clothing and low heeled shoes

5. You will need to arrange for transportation, preferably someone who can stay and wait with you

6. Expect to be at the facility for approximately one hour.

Go "Flapless" with PRK

What is PRK?

* Soft contact lenses need to be removed 2 weeks prior to pre-op and/or wavescan appointment(s)

* RGP contact lenses need to be removed 3 weeks prior to pre-op and/or wavescan appointment(s)

PRE-OPERATIVE INSTRUCTIONS

1. If you wear contact lenses (hard, gas permeable, or soft) remove them at least 3 weeks before your pre-operative appointment. The Doctor may give you more specific instructions for your individual care.

2. Remove all make-up and earrings the day of the procedure.

3. Abstain from wearing perfume, cologne, after-shave, or scented body lotions. Fragrances interfere with the laser beam.

4. Wear comfortable loose clothing and low-heeled shoes.

5. You may eat a light meal the day of the procedure.

6. Continue to take any of your routine medications.

7. You may have a prescription to have filled before the procedure. Bring this medication to the laser center with you.

8. You can anticipate being at the laser center for about 1-2 hours. We ask that you arrive 1 hour before the procedure is scheduled.

9. You must have a driver available to provide transportation to and home from the laser facility.

Cataract Surgery IN GILBERT, AZ

Multifocal Intraocular Lens Implants

There is a new generation of intraocular lens implant available that not only provides improved distance vision- it can provide improved intermediate and near vision too. These intraocular lens implants, or IOL’s, can potentially eliminate dependency on glasses or contact lenses for most activities such as driving, golfing, skiing, computer work, and reading.

For patients that HAVE been diagnosed with visually significant cataracts these lens implants are an alternative to receiving the conventional monofocal lens implants. Medicare and other insurance companies will cover the cost of cataract surgery (this includes a conventional monofocal lens) for patients that qualify(subject to copays, co-insurance, and deductibles). Patients electing for monofocal IOL’s typically have both eyes corrected for clear distance vision, but they have to rely on reading glasses or a form of bifocal glasses for intermediate and near vision. Patients have the option to upgrade to a premium multifocal IOL. The costs of upgrading to a premium IOL are not covered by Medicare and private insurance, but recent changes in Medicare law now allows patients to pay out-of-pocket for the additional costs associated with these IOL’s. Patients receiving multifocal IOL’s will no longer have the routine expense of purchasing glasses. They will now be able to wear fashionable sunglasses without a prescription and will be able to enjoy activities free from glasses or contact lenses!

For patients who HAVE NOT been diagnosed with visually significant cataracts this intraocular lens implant is STILL AN OPTION to consider if there is a desire to eliminate glasses. Before these new technology IOL’s were available, a patient’s only option was to have a refractive procedure (RK, LASIK, or PRK) that could not – and still cannot – correct both eyes for clear distance, intermediate, and near vision. In time, many of these patients would develop cataracts and their vision would decrease, and many would eventually require cataract surgery to once again improve vision. A clear lens extraction procedure is similar to cataract surgery. The difference is that instead of removing a cataract (a cloudy lens), the clear lens of the eye is removed and the multifocal IOL is used as a replacement. One of the benefits to this option is that patients who undergo this procedure will never develop cataracts in the future because the lens of the eye has been removed and replaced already. Another is that while Medicare and private insurance companies do not cover this option, patients do not find themselves paying out of pocket for a LASIK or PRK procedure then again paying the copays, co-insurance, and deductibles related to cataract surgery. Finally, patients that have had LASIK or PRK that now need cataract surgery have a greater risk for a “refractive surprise” and may find they need additional surgery or laser treatments to reach their refractive goal. A refractive surprise can occur because the natural corneal tissue is reshaped with LASIK or PRK resulting in altered corneal measurements. Corneal measurements are one of the measurements used in the formula to calculate the power selection for the intraocular lens implants (conventional or premium).

Surgeons cannot guarantee results with ANY surgery or procedure regardless of intended results. Risks, benefits, alternatives, and complications will be reviewed with every surgery patient individually.
